Why do we not see super zoom lenses starting in wide angle?

In order to make ultra wide angle lenses, a retrofocal group is usually used. The retrofocal group is essentially a reversed telephoto at the back of the lens. Now, to transition from the ultra wide ...

Use a fisheye lens on APS-C camera as ultra wide angle

A fish-eye lens is not just a lens with a very short focal length, it also has a specific distortion (cf. fish-eye projection vs. rectilinear projection). So while you can use a full-frame fish-eye ...

Why use ultra-wide with short focus?

A very good way of using an ultra wide lens is to get really close and get something right in the viewers face. Using a wide angle lens to get everything in the frame often leads to very boring ...

How important are lens hoods on ultra wide zoom lenses?

It is going to depend a lot on the ultra wide angle lens. For Nikon for example both the Tamron 15-30mm f2.8 (comes in other mounts too) and the 14-24mm f2.8 have a non-removable lens hood to protect ...

How important are lens hoods on ultra wide zoom lenses?

I use lens hoods almost religiously. My 70-200mm never comes out of the bag without it. Ditto for any of my other zooms or primes above 24mm. Indoors in totally controlled studio lighting I sometimes ...

Ultrawide Micro Four Thirds lens: is it better to use a wide full frame lens with a Speed Booster or a native lens?

It's better to get the native lens. Because you will never find a low-cost 15-30mm equivalent rectilinear lens for MFT in full-frame glass. You do get, that even with a speedbooster at x0.71, that ...

Are there any off-the-shelf USB camera modules that can capture a very wide angle from up close?

The camera and lens will have some depth themselves so you need even more vertical space under the glass plate. My suggestion would be to employ a folding mirror. Place a mirror under the glass plate ...

Why do some lenses have a rounded front element?

It can see 180°. To achieve that it has to be proud of the barrel. All [or at least most] lenses have a convex front element - but they don't have a field of view so wide that their own barrel will be ...

Why do some lenses have a rounded front element?

The two basic shapes of lenses are convex (bulge outward) and concave (bulge inward). As light traverses a lens, the lens shape plus its hardness causes the light to change its travel direction (...

21mm + 28mm combination for backpacking purposes, is it too close?

The difference between 21mm and 28mm doesn't sound like all that much. But as focal lengths get shorter the difference per millimeter in focal length gets larger. In theory a 21mm lens should yield ...

How do you protect ultrawide angle lenses with a bulbous front element?

To protect the front element of my Nikkor 14-24 with protruding front element while actually shooting, I took a high grade sheet of clear plexiglass and dremmeled a disk out of it roughly 1.5" wider ...

Is there a sweet spot in distance to a subject when shooting with an ultra wide angle lens?

It has very little to do with focal length directly. Perspective distortion is caused by one thing and one thing only: Shooting distance. The reason we notice it more when using very wide angle ...

Crop factor gives an equivalent FOV/enlargement, not an equivalent perspective per-se as that is solely dependent on subject distance. Crop factor cannot account for lens specific distortions... i.e. ...
