Tokina 11-16mm f/2.8 AT-X116 Pro DX for Nikon and for Canon
Nikon’s DX zoom lenses like the 18-55mm start at 18mm (27mm after crop factor) which is just starting to get into the wide angle arena. Most of the time this gives you a wide enough field of view (FOV) and if you need to get more in then you can just back up. There are times though when you can’t or don’t want to back up. Sometimes you might want a wider FOV to get a different perspective in a shot. It’s not just about “getting it all in”, but rather looking at a shot differently and getting the composition you want.
I had never shot a DX lens wider than 17mm or one with a constant f/2.8 lens. We can see the difference in FOV between the Tokina 11-16mm, Nikon 18-200mm and Nikon 35mm:
11mm is wide, really wide. The test shots above were taken at about 5 feet from the TV. The first thing I notice in the 11mm shot is the perspective distortion, but that isn’t necessarily bad. The Nikon 18-200mm presents quite a bit of barrel distortion at 18mm. The Tokina gives nice straight lines, but going so wide starts to affect perspective. Things at the edge of the frame in this situation look stretched because of perspective distortion.
The best way I can describe perspective distortion is that the ultra-wide focal length allows you to move the camera forward into the scene. This has a large impact on the size of subjects depending on their distance from the camera. Subjects in the foreground will appear larger in size than subjects in the background. You can see this in the shot of Mt. Shasta below, the foreground right in front of my feet is balanced against the huge volcano in the distance. You have to use that foreground emphasis to your advantage and it is surprisingly hard to do. That’s about the best I can explain it, but you can read more about perspective distortion on Wikipedia.
The Tokina 11-16mm is a very interesting lens and can be considered special purpose. It’s definitely not for close up portraits as the perspective distortion can wreak havoc on your subjects’ faces if you aren’t careful. For a more distant portrait like my wife in front of Haystack Rock you can get away with it. Keeping the subject in the very middle of the frame helps avoid unflattering distortion like me with the moose in Coeur d’Alene.
The lens itself is very solid and well built. The focus ring pulls in and out to switch between autofocus and manual focus. I’m very happy with the lens and has whetted my appetite for more “pro” lenses, especially with a constant f/2.8. Overall this lens is a very good value.
For Nikon users, depending on your camera you might want to look at the comparable Nikon 10-24mm f/3.5-4.5. The Tokina does not have a built in autofocus motor so it will not be able to autofocus on bodies missing the motor to drive non AF-S lenses. The lower end bodies like the D5000, D3000, D3100, D40, D50, and D60 do not have the motor so the Nikon 10-24mm becomes your best option. The D70, D80, D90, D200, D300, and D7000 are all good to go.
Canon users will run into a similar situation if your body does not include an autofocus motor then you’ll want to consider the Canon 10-22mm f/3.5-4.5. The only problem with the Nikon and Canon versions is the higher cost, slower apertures and more distortion.
The Nikon version is about $600 from Amazon and the Canon version is about $700
