They're wide because they capture a lot of what is in front of you. It's mainly useful for landscape and architecture shots. My photo on 30 August was taken using a wide angle:
valerie--awesome question, and i appreciate the responses! vikdaddy--that shot was amazing! and dorrena, i checked out each of these links and they are so helpful. thanks all!!
I shoot with an ultra wide Tokina 11-16 and I love it for landscapes. I haven't used it as much in the manner that that Ken Rockwell discusses but I've only had it a few months.
Here are some shots that I have taken recently with it:
And this one shows what the Rockwell article talks about a little bit:
someone should take and post two photo's of the same subject from the same spot one with 50mm and one with wide angle that would show one of the differences
Justin, how wide does a lense go before it is called a fisheye?
Richard,
Regarding the fisheye, I'm not really sure. I think Nikon sells a 10.5 mm fisheye, which is only a 0.5mm difference from my ultra wide. I think it has more to do with the distortion of the lens rather than the mm.
Just to muddy the waters a bit more. Don't you also have to take in account your Camera's sensor and it's crop factor for the field of view. On a cropped sensor camera a wide 28mm lens behaves much like a 50 mm lens would on a full frame sensor camera. So, for a more faithful wide shot on a cropped sensor you need to go down to the 20-15 mm range..correct?
I heard that too, David. I wasn't impressed when it actually meant that my 18mm was more like 27mm! Haha. But it does mean I can get away with cheaper telephoto lenses... Kind of. :)
they fit in alot more then the standard lens fits in .. i love my 10-22mm . i love landscapes so it works well for me .. depends on what ur passion is in photography .. But truely i love mine !!!
@ Richard R Tuckey, they are fisheyes because the distortion is maintained instead of corrected within the lens. Theoretically you could have a fisheye in a 20mm but there wouldn't be that much distortion, so if you go down to 10mm like my Canon ultra-wide angle lens but maintain the distortion it would act very much like a fisheye.
@ David Michaels, yes you're right, my 10-22 is in effect a 16-35mm(ish) on my crop sensor.
A true fisheye lens should give you at least a 180 degree diagonal field of view. A lot of the fisheye attachment lenses are true fisheye lenses because the field of view is a lot narrower than that, they just introduce a lot of barrel distortion.
The widest non-fisheye lens that I know of is the Sigma 12-24mm f/4.5-5.6 EX DG HSM on a full frame sensor or a Sigma 8-16mm f/4.5-5.6 EX DC HSM for a 1.5x crop sensor. Those are crazy wide.
A few examples from my sigma 12-24.
When working with infrared, you've gotta pick your lens carefully since many wide angle lenses have bad hot spots. The sigma 10-20mm DC, sigma 12-24mm DG, and Nikkor 12-24mm DX all have really bad hot spots. My Nikkor 17-35mm performs great in IR with no hot spots.
