One of the problems with Digital Single-Lens Reflex cameras (DSLRs) with the usual APS-size sensor, is that because of the "digital multiplier" effect from the smaller sensor the focal length of any lens is, in effect, half again as long as it would be on a full-frame DSLR or film SLR. That means that an 18mm lens, for example, which was considered a really wide angle lens on a film camera, is effectively a 27mm lens on an APS-sensor DSLR. A 28mm lens, wide-angle on film, is 42mm on APS - nearly a normal lens.
In recent years zoom lenses have become available which have a low end of 12mm, which is equivalent to the 18mm full frame wide angle. I've had a Tokina 12-24mm for several years. This picture was taken at 12mm on that zoom:
I gave my old wide zoom lens to my daughter-in-law when she and my son visited on New Years Eve, and replaced it with a new Nikon 10-24mm zoom. I have to say that I really like it. The lens is light and smooth operating, and seems quite sharp.
The difference between 10mm and 12mm at the low end doesn't seem like much, but it really is a big difference in terms of angle of view - 99 degrees vs 85 degrees horizontal, and 76 degrees vs 66 degrees vertical.
These are the first pictures I took with the new lens - They were taken from only a few inches away from Natasha, and you can see the exaggeration of scale which such proximity at such a wide angle causes:
Of course, that distortion makes this something less than desirable as a portrait lens...
