Wide angle lenses for small sensor APS-C DSLRs

Published by: Photo.net       06-26-2005        Read Complete Article
Article Summary

One of the disadvantages of small sensor APS-C Digital SLRs (basically everything but the Canon 1D and 1Ds series cameras) is that the 1.6x "multiplier/crop" factor makes all your existing 35mm wideangle lenses into "not so wide" angle lenses. Nikon cameras are slightly better, with a 1.5x "multiplier/crop", but still basically suffer from the same problem. On a 20D or Digital Rebel XT your 24mm lens has the same field of view as a 38mm lens would have on a full frame camera. Your wide 20mm becomes a moderate 32mm and even your superwide 16-35 zoom becomes a mid-range 26-56 lens. Even the widest rectilinear prime lens you can get for 35mm a 14mm - turns into only a 22.5mm lens.

So what can you do? Well , you have to turn to one of the new ultrawide zooms made specifically for small (APS-C) sensor digital cameras. While Nikon and Canon have had their own wideangle lenses for a while, there are now also four "3rd party" alternatives available.....Read Complete Article

Canon EOS 20D, 30D, 5D or Nikon D200?
Many potential buyers of a new Canon mid-range DSLR will now be wondering one of (at least) four things:

  • Is it worth upgrading from (or to) an EOS 20D to an EOS 30D?
  • Should I get an EOS 30D/20D or an EOS 5D?
  • Should I get an EOS 5D or Nikon D200?
  • Should I get an EOS 30D/20D or a Nikon D200?<......

Comparing the EOS 5D and the EOS 20D
"You might think that it would be pretty easy to compare imags from a EOS 5D (full frame) with a EOS 20D (APS-C), but it's actually more difficult than you might think. You need to compare apples to apples, not apples to oranges and that's not quite so easy as it sounds. There are perhaps four different ways that you could use to compare image qual......

The writing on the wall
Like it or not, digital rules. Digital Audio, in the form of CDs and MP3 players, have taken over the roles previously occupied by vinyl disks and analog cassette tape. TV and radio are going digital, more so in Europe than in the US, but the US will surely follow. Cell phones are digital. Computer data is digital. Why should photography be any dif......

A Photographer's Guide to Ecuador, the Galapagos, and Peru
Ecuador and Peru offer the possibility of, within just two or three weeks, simultaneously challenging your wildlife, landscape, architecture, and people photography skills.

In the Andean highlands you can photograph a civilization built on the slopes of granite mountains where people can look up 3000' from their frontyards to the snow-capped ......

Sunday Morning Photographer: Keeping Up
Good morning. You know, every now and then I start to write one of my characteristic little rants about how annoying it is to wait for vaporware. We all have stories - well, most of us - I'm sure; with me lately it's the Sigma 30mm that was announced way back in February and that Sigma told me would be out by the end of May. I'm not exactly hot to ......

Comparing the Canon EF70-200mm F2.8L IS with a 1.4x and 2.0x Extender
I purchased Canon's current (as of early 2005) 1.4x and 2x teleconverters for three purposes:

  • To get a bit longer reach from my kit, so that I could (hopefully) dabble in wildlife and bird photography in 2005;
  • to learn longer-lens techniques inexpensively;
  • to delay the purchase of a long telephoto until I could determin......

Sunday Morning Photographer: Why 40mm?
40mm has long been my favorite focal length for 35mm cameras. I got "turned on" to the focal length when I interviewed Sally Mann for Camera & Darkroom magazine in the 1980s. She told me she had supported her artwork by doing lots of small freelance jobs, including many for the local military academy. She said she used Olympus OM cameras, and that,......

Canon EF 300 vs. EF 75-300mm Lens Review
I see a lot of "users" commenting in on-line forums that the Canon EF 75-300 lenses are very soft, especially at 300mm, sometimes commenting that the lens is "unusably soft". While I agree that they aren't the sharpest lenses, I often wonder just what these users are seeing. I wonder if some of them are just repeating "conventional wisdom", which i......

Tokina AT-X124 Pro DX 12-24mm F/4 Review
With the increasing popularity of digital SLRs with smaller than full frame digital sensors, there has come the demand for wide angle lenses specifically designed for this format. The Tokina AT-X124 Pro DX is one of several new lenses intended to fit that need. It's field of view when used on a Nikon DSLR and other 1.5x crop cameras, is equivalent ......

The affordable 7" Digital Camera LCD Viewer
In the 'old' days we used to pass Polaroids around the studios to clients, art directors, teachers, etc. Now that I have switched to DSRL I really don't feel like passing around my camera nor do I enjoy holding it while everyone has a chance to look at the image(s). So, I set out to find a solution that would allow instant playback with an image la......

Tamron SP AF28-300 Review
I dare say 28-300mm zooms feel the same way. They don't get no respect either! There seems to be a "knee jerk" reaction whenever they are mentioned on photo forums. No sooner does someone ask about one than the disparaging remarks start up. So does the Tamron 28-300 deserved respect? Read on to find out.......

Using Image Calibration to Reduce Noise in Digital Images
This article is about a method of reducing noise in images taken with digital cameras - especially long exposure and/or high ISO images taken with digital SLRs. The simplified workflow presented here is derived from more advanced techniques of noise reduction (known as calibration) that are used in scientific and technical imaging. Because of limit......

Pixel Peeping Part I
Since digital cameras (and especially DSLRs) first became popular there has been an epidemic of what might be termed "Pixel Peeping". Pixel Peeping is a secretive activity practiced by some photographers in their basement and involves repeated photographing of resolution charts and grey cards, followed by manipulation far beyond the bounds of norma......

Field of View - Fisheye and Rectilinear Lenses
With the advent of digital cameras having non-standard sensor sizes there seems to be quite a lot of confusion concerning focal length, field of view and digital multipliers and how they relate. This article is intended to try to clear up some of that confusion.......

The Future of Digital - Full Frame or APS-C
There's lots of discussion these days on whether digital will move to "full frame", meaning sensors which are 24x36mm, or whether a smaller frame size will "be good enough". The smaller frame format is usually called APS-C and is the typical "1.6x multiplier" format used by many manufacturers (Canon, Pentax, Minolta and Nikon - though Nikon have a ......

Canon's New EF-S Lenses
The first, and to me possibly the most interesting, of the new EF-S lenses is the EF-S 10-22/3.5-4.5 USM. 10mm is the widest lens available for a small sensor DSLR. Sigma make a 12-24/4.5-5.6 EX DG (with full frame coverage) and Nikon have an AFS 12-24 mm f/4 G ED IF DX (with coverage for their 1.5x sensor). Of course the angle of view with a 10m......
