Can A Samsung S6 Camera Lens Be Repaired
Despite buying cameras which have been specifically designed to have and make use of different lenses, a large number of photographers just always use the kit lens that their DSLR or interchangeable lens camera came with. Only information technology'due south really not that surprising, picking the correct next lens tin can be daunting, which is why we're going to try to help with our guide to life subsequently the kit lens.
Lenses are arguably the near important part of your camera ready-up, they make or pause your pictures. They control the image that'south projected onto your imaging sensor, and ultimately what photos you are taking home. As such, many photographers would prefer to shoot with an okay camera and a cracking lens, than a groovy photographic camera with ho-hum glass attached. But knowing the importance of adept glass is ane affair, it'southward another to know what lens volition requite you the creative liberty to capture the photos y'all want to get.
To the uninitiated, lenses are baffling tubes of glass with numbers and confusing acronyms printed on the side. Hopefully, this guide will assist you understand which lenses can be used to achieve what, why others tin price more than than a family motorcar … and how there are some sub $150 bargains which could change your photography forever.
Which lens should I buy side by side?
If you currently merely have the kit lens your camera came with, the brusk answer to this question is that as soon as you lot have the cash available, y'all should go out and become a fast normal prime lens or a telephoto zoom. The longer and more considered answer is that you need to think about the blazon of photographs you currently take. You lot demand to understand how different lenses could amend your current photos and allow you to accept ones that you currently tin can't. If that all sounds a bit disruptive, read on.
Decoding the lens jargon
The almost sentence-long drove of letters and numbers on the side of a lens barrel tin tell y'all all sorts of things virtually a lens. But the details which you should probably pay the virtually attention to are those which particular the focal length, maximum discontinuity, lens mount and format type.
Focal length
Focal length is expressed in mm and a higher number means a bigger zoom, while a lower number mean the lens can be used for wider shots. Every bit a crude reference, the man eye is said to see about the equivalent of 30-50 mm on a total frame photographic camera (more than on that later). A number lower than 30-50 mm will have in a bigger view than you lot naturally see, while college numbers mean focus will be on a smaller aspect of your view.
If the lens has a focal length range with two numbers (say 24-lxxx mm) this means it's a zoom lens and is capable of zooming and beingness used at any indicate across that range. Yet, if at that place is a single focal length number (l mm for instance) it'due south a prime number lens, so taking in more or less of the view volition crave you to become closer or further away from your subject. Traditionally, primes have been considered to exist optically superior to zooms, because trade-offs have to be fabricated when producing zoom lenses. But that'south not to say that some zooms are not amend than some prime lenses.
To brand understanding focal length more difficult, the aforementioned focal length lens gives different views on cameras with diverse sensor sizes, because of the crop factor (the sensor but takes up function of the projected image). Every bit a upshot, many manufactures give a 35 mm-format equivalent on lenses designed for cameras with smaller sensors and in this article descriptions are based on on 35 mm-format. Therefore, if your camera has a smaller sensor, and at that place'due south a adept chance it does, you'll demand to consider this when deciding which lens yous need.
If y'all're using a full frame camera in that location's no calculation needed, a lens volition give you the field of view yous'd look from its number. If your camera has an APS-C sensor (Nikon DX DSLRs, Sony NEX…) it has a ingather factor of one.v - meaning you multiply the lens focal length by 1.5 to get its equivalent 35 mm-format focal length. For Canon APS-C cameras that number is 1.6, for Micro Four Thirds cameras it's ii.0 and for the Nikon 1 serial information technology's ii.vii.
That means a 35 mm lens would give a field of view equivalent to 56 mm on an APS-C camera similar a Catechism 70D and equivalent to seventy mm on a Micro Four Thirds photographic camera similar the Olympus OM-D E-M1. On a Nikon ane it would deed like a 95 mm lens does on a full frame camera.
Maximum Aperture
Maximum Discontinuity is shown in a number of ways, simply whether it's f/2.8 F2.8 or 1:two.8, it all means the same thing and refers to the the maximum corporeality of calorie-free which the lens can gather. Lenses with larger maximum apertures (slightly confusingly these are the ones with lower numbers) are capable of gathering more light.
As a F1.eight lens is able to use more light than an F4 lens, this means information technology could be used in lower-lite situations without having to use a wink, and is capable of producing a shallower depth of field (the function of the image that is sharp) equally shown below.
Some zoom lenses have a variable maximum aperture pregnant that it changes depending on focal length. And then, while a 18-200 mm F3.five-5.6 lens would have a maximum discontinuity of F3.5 at eighteen mm, it would be be F5.6 by the time you zoomed to 200 mm.
Lens Mountain
It goes without maxim that you want to purchase a lens that will attach on your camera, and this is known every bit the lens mountain. Camera manufacturers mostly make lenses with proprietry mounts which will only fit their devices, sometimes having multiple lens mounts for different camera lines. The major exception to this is Micro Four Thirds lenses which can be used on respective Olympus and Panasonic cameras. Third party manufacturers also make lenses with mounts to fit various brands.
It'due south important to know which mount your camera uses before heading out to purchase a lens. Example lens mounts for DSLRs include the Nikon F-mountain, Catechism'southward EF or EF-S, the Pentax K and Sony'southward Blastoff (A) mountain. For mirrorless interchangeable lens cameras, these are things similar the Canon EF-M, Fujifilm XF, Nikon 1, Sony E, Samsung NX and Pentax Q. Every bit mentioned earlier, Olympus and Panasonic Micro Four Thirds cameras have whatever Micro Four Thirds mount lenses.
Format
In addition to being able to mount the lens on your camera, you need to be sure it volition produce an image big plenty to comprehend the image sensor. Considering different cameras use different size sensors, manufacturers produce specific lenses to work with them.
For example, while Nikon DSLRs come with full frame or APS-C sensors - and both have F-mountain lenses - its DX lenses only produce an image big enough to cover the smaller of the two sensors. Meanwhile, FX lenses comprehend the full frame and can also be used on DX and even Nikon 1 cameras (with an adapter). This is washed considering lenses designed for smaller sensors tin can be physically smaller and lighter themselves.
Different types of lens
Lenses are more often than not categorized past their focal range or specific role if they're a specialist lens. Below we've taken a look at a few of the nigh mutual types of lens, thought about the characteristics their images are said to have, and considered how they can be used.
Ultra Wide
What they are: Ultra Broad angle lenses have a focal length of around less than 24 mm (in 35 mm-format), this means they can take in a wider scene than is typical, though they're non just about getting all of a subject into a shot. Rectilinear ultra wides help keep straight lines, just that, while fisheyes will reproduce buildings with curved walls.
Epitome characteristics: Because of the wide field of view, shots with ultra wide angle lenses typically characteristic a big depth of field. Images tend to pull in subjects that are close, and button away more than distant ones making them appear further apart. Perspective distortion of ultra wides can give falling-building-syndrome (where vertical lines converge) only this tin be corrected in postal service-processing, or minimized with good technique.
What they are used for: While oftentimes seen equally a specialist lens, ultra wide angles tin be used in a number of ways. Typical uses include landscape, architecture and interior photography. Even the distortion can exist used creatively, specially when using fisheye lenses.
Wide Angle
What they are: Typically roofing a focal length betwixt 24 mm and 35 mm, Broad Angle lenses are available every bit primes or zooms and come up with either variable or fixed maximum aperture. Offering a broad field of view, they often as well avowal close minimum focusing distances.
Prototype characteristics: Wide angle photographs can magnify the perceived distance between subjects in the foreground and background. Wide angles suffer less baloney than their ultra broad counterparts, simply yous even so get an exaggeration of lines and curves which can be used artistically.
What they are used for: Many people simply reach for a wide angle lens when trying to get the whole of a subject area in frame, whether that'due south a building, a large grouping of people or a landscape. However, while those are perfectly adept uses of one, they tin can also exist used for interesting portraits where yous want to place a bailiwick in a situation. Just be conscientious not to distort faces unflatteringly by shooting besides close.
Standard / Normal
What the are: The kit lens your DSLR or interchangeable lens mirrorless camera came with is probably an example of a standard zoom lens, roofing a focal range of around 35-seventy mm. Ones with better optics and faster maximum apertures are likewise available. Many photographers consider a 50 mm prime (in 35-mm-format) as a normal lens, as it's said to reproduce an image with a angle of view which feels "natural" and like to what you see with your eyes - even thought this isn't technically true.
Image characteristics: Standard zoom lenses and normal primes sit between wide angles and telephotos in terms of image characteristics and are much more than like you lot see with the man eye. Normal prime lenses tend to have faster maximum apertures which can allow for a shallow depth of field and lower lite shooting.
What they are used for: As their name would advise, normal or standard lenses are versatile lenses which tin can be used for virtually all sorts of photography whether street, documentary, landscape, or portrait. Because normal prime lenses tend to feature faster maximum apertures, they let you to shoot with a shallower depth of field and in lower low-cal.
Telephoto
What they are: Telephoto lenses are those with a focal length in excess of 70 mm, though many people would contend that "true" telephoto lenses are ones which exceed 135 mm. They focus on a much narrower field of view than other lenses, which means they are proficient for focusing in on specific details or distant subjects. They are generally larger and heavier than equally specified wider lenses.
Image characteristics: Because they have a narrower angle of view, telephoto lenses bring far away subjects closer. They can also take the issue of compressing the sense of distance in a scene and making objects appear closer together. A narrow depth of field means that a bailiwick can exist in focus with a blurred background and foreground.
What they are used for: In improver to beingness used to photograph subjects you can't (or don't want to) get close to - like sports or wildlife - telephoto lenses tin be used for shooting portraits and even landscapes where their normalization of relative size tin exist used to requite a sense of scale.
Superzoom
What they are: Superzooms are exercise-it-all lenses which embrace focal lengths from broad to telephoto. They tin can be proficient for uses in situations where you tin can't or don't desire to be changing lenses and they normally change in length as yous zoom.
Image characteristics: Because compromises take had to exist made producing a do-information technology-all lens, superzooms exercise non have the same prototype quality of more than dedicated lenses and oft have slower and variable maximum apertures.
What they are used for: Offering a ane-lens package, superzooms come into their ain if you can't (or don't want to) change lenses. This could exist when in situations where it wouldn't be safe to switch lenses, or when travelling - you lot don't necessarily desire to exist weighed down by five lenses when on holiday with the family.
Macro
What they are: One of the more specialist lenses, marco lenses are technically those which are capable of reproduction ratios greater than 1:1. Nonetheless, the term is oftentimes used to refer to any lens which tin can be used for extreme close-upward photography. Macro lenses typically have focal lengths somewhere between 40-200 mm.
Image characteristics: Macro lenses normally have first-class image sharpness, though it's worth noting that when working at close distances they likewise have a tiny depth of field. You can often terminate upward with a shot of an insect where only a fraction of it is in focus.
What they are used for: Though normally used for close-up photography (at which they excel), macro lenses can also be peachy for portraits thanks to their typical sharpness and focal lengths.
Other things to consider
Size, weight … and price
With changes in focal length and maximum aperture come up some other set of lens changes, namely size, weight and cost. Ideally we'd all be wielding a sixteen-600 mm F1.eight lens. Unfortunately, non just does physics dictate that such a lens would need to exist huge and very heavy, it would likewise cost a fortune to produce, if it was fifty-fifty possible.
Equally such, any lens is going to make compromises to fit into a package of a size and weight which suits its users. Extreme focal lengths and larger apertures mean bigger and heavier lenses, which along with the bigger price-tags is why they are typically used past professionals who can justify purchasing them.
Prototype stabilization, build quality and video
There are a number of other features which y'all may want think most, regarding your next lens. Prototype stabilization allows for use of slower shutter speeds without suffering camera milk shake (though some brands incorporate this into photographic camera bodies rather than the lens). Stabilization is also very handy if yous're shooting lots of video, in which example yous might also want to call up near lenses with ability zooms which can zoom at adaptable speeds.
Weather-sealing means you lot can utilize your lens (bold your camera is every bit atmospheric condition-sealed) in extreme conditions conditions and commonly also means a higher level of build quality.
Other considerations include the utilise of special lens elements and coatings which tin amend sharpness and reduce paradigm problems such as chromatic aberration. Information technology'southward too worth thinking about whether y'all would benefit from a college number of discontinuity blades which tin give a more pleasing bokeh, and if you need lenses with internal focus motors, or indeed but manual focus.
Third party manufacturers
While the majority of photographers buy lenses from the aforementioned firm as their camera, in that location are a number of third political party manufacturers such as Sigma, Tamron and Tokina which produce lenses for DSLRs and mirrorless interchangeable lens cameras. Traditionally seen equally a less desirable selection, some of the newer 3rd political party lenses are as good if not meliorate than their Catechism/Nikon/Sony counterparts. They are oftentimes also considerably cheaper.
Examples of what lens to purchase
Below are a number of typical situations that kit-lens-toting photographers oft notice themselves in. For each case, we've highlighted some of the factors that should exist considered when trying to find the right lens for the job. While these are factors which are relevant any camera and lens system you're using, in each example we've as well highlighted a couple of lenses that would exist a skillful pick for specific set up-ups without blowing the budget.
I want an all-day / travel lens
When you're on holiday or traveling, you probably don't desire to be lugging several lenses and cameras effectually with you – unless yous're the most defended of photographers, that is. It's frequently the same if y'all're trying to savor a solar day with the family unit and don't want to spend all day changing lenses and moaning about your back.
Equally such, a good all-twenty-four hour period or travel lens would be i that was easy enough to carry effectually, merely yet offered you the freedom to capture shots from landscapes to portraits, and zoom in on distant objects. For Micro Four Thirds shooters, that could exist something similar the Panasonic Lumix One thousand Vario 14-140 mm f/3.five-5.6, or the AF-South DX NIKKOR 18-200 mm f/three.5-5.6G ED VR II if a DX Nikon is your DSLR or option.
I desire to do street photography
Street photography can be done with nearly any lens, though a 300 mm F2.8 might enhance a few eyebrows from your subjects. However, a focal range of around 35-50 mm is oftentimes seen equally the ideal for capturing the moment in urban areas.
Unless you desire all of your subjects looking direct at the camera, you'd probably be best served by something discrete. It'due south also of import that street photography lenses feature a fast maximum aperture for lower-lite situations. This ways that something similar the Fuji XF 23 mm f1.four R Lens would be a bully selection. The Sigma 35 mm F1.4 DG HSM has too been very well received by many DSLR street shooters.
I struggle to photograph my kids running effectually in the garden
Many people shell out for a DSLR or mirrorless interchangeable lens camera when they take a kid, but by the time that child starts running effectually, the kit lens struggles to continue upwards, both in terms of aperture and focal range. This is especially true if yous're trying to photograph the kids running effectually in the garden or on the sports field.
This means y'all need something with a bit more reach, merely probably without the bulk and weight that a professional lens would bring. A zoom lens will allow you to keep your shots framed every bit you want while your subject moves around in front end of you. And then, if yous feel yous simply need some added reach, the EF-S 55-250 mm f/four-5.6 IS Ii could become you closer to the action. But if you lot desire a scrap more speed (and to exist the best equipped parent at the game), at that place's the Canon EF seventy-200 mm f/4L USM.
I want to take landscape photographs
While the kit lenses which come with well-nigh cameras are surprisingly good at the broad bending stop, you could find that they don't quite get in enough for some of the mural images you endeavour to have. And so, unless you're able to keep moving backwards, you lot're going to demand a new lens.
Focal length is key hither, and yous'll only get some landscapes if you've got an ultra wide bending lens. Y'all could go for either a prime or a zoom, but most people in this situation are probably going to be best-served by a zoom. A lens like the AF-South DX NIKKOR x-24 mm f/3.5-4.5G ED could exist skillful for APS-C Nikon shooters, while the Olympus 9-18 mm f/4-5.6 ZUIKO would do the task on Micro 4 Thirds cameras.
I desire a lens which will make me amend as a photographer
After a while you might detect that you lot've simply outgrown your kit lens. Y'all suddenly find that it's stifling your creative ambitions and preventing y'all from taking the photos that yous want, even if they are within its focal length reach.
This is the ideal time to go yourself a fast prime lens, and the good news is that you don't have to spend a fortune to do information technology. Getting something like a Nikon AF-Southward DX NIKKOR 35 mm f/ane.8G or the Sony E fifty mm f/one.8 OSS will hateful yous can play around with shallower depths of field, and shoot naturally in conditions that would have otherwise required a flash. Because they are primes, information technology also means y'all need to zoom with your anxiety, which volition in turn probably mean yous spend more fourth dimension thinking nigh how you compose shots. Never a bad thing.
Summary
Equally nosotros've seen, different lenses can give photographers the creative freedom to take all sorts of images. It's no understatement to say they are as important, if not more so, than the camera y'all're using. This is why it's such a shame to see photographers buy cameras with the ability to modify lenses and and so never exercise then.
It's worth remembering that lenses can often last longer than your camera, because they volition continue to work on the next generation of cameras, and the one after that, probably. This is why many photographers are willing to spend more than on an individual lens than their camera.
Notwithstanding, ownership new lenses doesn't have to hateful spending a fortune. We've seen how relatively cheap primes like the nifty-l (50 mm F1.eight) tin can change your photography forever. There are also thousands of 2nd-manus lenses which will work just as well as new ones out at that place – especially for DSLR shooters, where yous tin can often use a 20-twelvemonth-one-time lens. You never know, your begetter might even have some lying around in the attic.
Hopefully this commodity hasn't made y'all feel compelled to buy more and more lenses, as that actually wasn't the aim. If you lot're non sure if you demand a new lens, you probably don't. Instead, we hope this has helped yous empathize what to look for when yous experience that your current lenses are preventing y'all from being the photographer you want to be.
