 | Learn aboutLens availability |
Snapsort provides the approximate number of lenses available for each brand of SLR. This includes lenses made by third parties, for example Sigma makes lenses that are compatible with Nikon DSLRs. This can be an important factor when buying a DSLR. People often own SLRs for many years, and as they improve their photography skills and knowledge they may find themselves limited by the kit lens, and start buying additional lenses. Snapsort does not include lenses that you can use with an adaptor in its counts, so often you can make use of more lenses than stated if you buy an extra adaptor.
Specialized Lenses
Here are a few types of specialized lenses you can buy for DSLRs.
Wide-angle
Wide-angle lenses, e.g. 24mm or lower, add an interesting perspective and let you capture huge scenes and/or great shots in tight spaces.
This photograph demonstrates the effect of a very wide-angle lens (14mm), while capturing a huge amount of the scene it also distorts, more so at the edges, taken with a Nikon D700 DSLR. Photography by realSMILEY via Flickr. f/5.6, 1/50s, ISO 200, 14mm. Telephoto
Telephoto lenses, e.g. 85mm or longer, let you get close-up shots of subjects far away from you, and are create flattering portraits of people.
Using a telephoto lens can get your close to the action without putting yourself at risk, this shot was taken (in a zoo!) at 500mm with a Canon 5D Mark II DSLR. Photography by Todd Ryburn via Flickr. f/4, 1/400s, ISO 1600, 500mm. Wide aperture
Wide-aperture lenses, e.g. f/2.8 or wider, capture a lot of light letting you get natural light shots you couldn't otherwise get, and have a narrow depth of field to blur the background (bokeh).
Here you can see only some of the leaves are in focus due to the narrow depth of field achieved with a f/1.2 lens using a Nikon D40 DSLR. Photography by jorritf via Flickr. f/1.2, 1/640s, ISO 200, 50mm. Macro
Macro lenses enable you to focus very very close to a subject, great for photographing details such as leaves on flowers or small insects
Here we small details made large using a macro lens which can focus very close to the ants, taken with a Canon EOS 350D DSLR. Photography by linh.ngan via Flickr. f/4, 1/800s, ISO 100, 40mm.

This is a very good idea but soon the grafic would be overcrouded.
Maybe if one represents just the largest aperture resulting in lines and dots it would be easier to read.
1) More lens is not necessary better than less
2) Some brands uses stabilization on the lens Nikon (VR), Canon (IS), Sony moves compensation inside the body.
3) Better motors, faster lenses and reasonable prices could be more important than the number of lens.
Now how to improve that?
I have an idea that is relatively simple to implement in a DB and could be a nice addition to sites like snapsort and lenshero.com.
Imagine a plane where the X axis represent the focal length and the Y axis the aperture. A fix/prime lens will be represented
by a vertical line connecting the two extreme points in the aperture. A zoom lens will be a rectangle covering the range
in focal distance and aperture for that lens. Collect all those geometrical objects and we can extract much better metrics
than the simple count of number of lens. For example
1. Coverage: Compute the convex hull (See wikipedia) of the superposition of the corners of those lines and rectangles and
you will get a fairly good idea how brand covers a wide range of focal range and apertures for a given camera.
2. Geometric density: Associate a width to each line in the figures before, make a fine grid and count the tiny squares that
the zooms and primes lens are covering. In this case the more overlapped a region is, higher will be the coverage.
3. What about Auto focus, stabilization, better motors and price? Add more dimensions to the plane, associate a weight factor to them.
and you will get a very rich and fairly complete metric that could help your visitors to decide if a specific camera/brand will
fit his/her expectations in terms of lens.
Do you want to go for the best?
Use a javascript tool such as D3.js to present the figure that I describe to you in a nice and interactive way. The quality of a website
like lenshero.com will shine even more than it is doing right now. With your filters as those you already apply on lenshero to target
prices, more or less lens will be covered and more or less lines and squares will pop up in your plot. Setting colors for DX or FX,
VR/IS vs Non-VR/IS will help visitors to visually understand how different brands try to cover a market full of complex and sometimes
cryptic codes.
Congratulations for your great sites (snapsort.com and lenshero.com) those data-based review sites are a great step forward
from the typical subjective consumer reviews that are so common on internet.
Thank you
availability" i supouse to see all lenses for those model . list at least, and no childish explanation
I have 4 of them and I would like to use the also with a mirrorless camera.
can somrbody advise me on it, thanx
I had not seen lenshero. That's a nice site. Thanks. Not quite as mature as Snapsort (I ran into a few errors in the first couple minutes of use), but still very useful. You may be interested in Dyxum as well -- it's a very similar site, but specific to Sony a-mount; it's more comprehensive, but not as well organized. It might give you some ideas.
On an unrelated note, the site also seems to over-weigh camera popularity, and not capture either ergonomics or ultimate image quality at all (better image processing algorithms are probably the primary reason Canon cameras are as good as they are relative to the competition).
Have you seen our sister site http://lenshero.com? We might integrate the two sites further, giving Snapsort more specific information on types and prices of lenses available for each system!
1) All lenses are stabilised. This substantially reduces the need for overlap in lenses. Canon makes a number of lenses in IS and non-IS versions. This makes no sense in a Sony or Pentax. This is not an advantage for Canon or Nikon, but your metric makes it into one.
2) I can get lenses for Sony and Pentax where I cannot have similar functionality for Canon or Nikon at any price. I do most of my shooting in low light, so I use fast prime lenses (mostly, an older Maxxum 50mm f/1.7). This gives me a high ISO sensor, fast lens, and image stabilization in one, cheap package. Neither Canon nor Nikon made any fast (f/1.8 or better) IS lenses until you get into telephoto. On Sony or Pentax, I can do f/1.4 or f/1.2 IS at any lens length. I cannot overemphasize how much of a win this is for the type of work I do.
Second of all, what matters is lens selection, which doesn't really come down to number of lenses. Sigma makes 4 superzoom lenses. Tamron makes 3. All of the major manufacturers make at least one. It makes little difference whether there are 10 superzooms for a mount, or just 1, so long as there is at least one good, reasonably priced model. Something major missing (such as Pentax's lack of a cheap 50mm) hurts. This should be weighed in some way. In the same way, not much of your reader base cares about the availability of Sigma's 200-500mm f/2.8 monster for $26k, and if they do, they'll buy a camera body to go with it. The key question is about having a good spread of available consumer-priced lenses, not just raw numbers.
Third of all, used lens availability and price matters a lot. Canon and Nikon have good availability, but high prices. Old Minolta lenses for Sony are very nice and extremely affordable, and easily found on eBay, but less easily found in stores or Craigslist. I have not looked at the others, but I would guess many of the declining brands will have great availability.
