What is the purpose of this 0.8x wide angle? I mean, you get wider image, but isn't that the same if I just go some steps back? No, it is not the same. A wider angle lens (whether due to a front- …

Generally no. The camera on most cell phones provides a field of view equivalent to a 28mm lens on full frame, give or take. That's roughly like the field of view of the long end of 10-20mm on an APS- …

Here's three possibilities I can think of, in order of increasing grasping at straws. However, we only have your subjective impression to go on, and that's kind of vague, so I can't really weigh in me …

One option is to use a zone plate optic with a wide-angle converter lens in front. An off-the-shelf solution is Lensbaby's zone plate optic + wide angle 0.6× or super-wide angle 0.42× conversion kit. …

No, that lens won't work with a D3000, because it's for the new "Nikon 1" system, which uses a smaller sensor and a different (smaller) lens mount. (And, because of that system's smaller size, note th …

To fill the frame with your subject with a wide angle lens, you have to be really close. Perspective — the way lines map from 3D reality to a 2D surface like a photograph — is naturally strongest with …

When a field of view is described as 120°, that refers to the total angle. So, 60° to the left of center and 60° to the right. Most camera lenses show a very restricted subset of the field of view pe …

Generally, in 35mm film terms, a lens around 35mm is considered to be "wide angle", and when it gets below 24mm, then we say "ultra-wide". There's no formal, official rule for this, but it seems to be …

There is overlap between the two terms, as you'll see as you browse the lists of both at LensHero. Basically, they're two different directions from which to approach the problem of narrowing down lens …

This is easy math, fortunately. 28mm is 1/6th larger than 24mm, and correspondingly, your selfie taken from the same position will be 1/6th wider. If you stay in the center of the frame, you gain an a …

There are several web sites which collect information on camera models and provide convenient ways to narrow down to specific options that fit what you need. My favorite is part of the the Neocamera s …

Wikipedia gives a very specific — but unsourced! – definition: a lens is considered wide-angle when it covers the angle of view between 64° and 84°. I think they're back-calculating that from the fiel …

Traditionally, lenses wider than 24mm on full-frame are "ultra-wide". On a smaller-sensor Canon DSLR, a 15mm lens provides that same field of view (16mm on Nikon, Pentax, or Sony; 12mm on Olympus/Pana …
