Extra wide angle Lenses

**seawolf66** · 10-Aug-2012, 15:01

I have seen some lenses use 1-8. and some use 1-12. and there are those that use 1-16 for being wide angle lenses
any body know what is a true extra wide angle lens in the angle aspect : lets stay around 100mm nothing below that please

Did you mean 108, 112, or 116 degrees?

just looking for information, since I do not know: I have a Wollensack lens which is 100 mm f-16

Lauren, maximum aperture has little to do with whether a lens is a wide angle. What are you trying to find out?

Focal length itself doesn't specify wide-angle, either... It's the angle of view that will determine image circle-- and format coverage-- for a given lens length. For instance, the are 90mm lenses as normals that barely cover 6x7cm format, 90mm lenses that cover 4x5 that are moderately wide, and 90mms that are wider still which will cover 5x7.

so you can have a bunch of 100mm lenses and you could have a variety of field of angle
on each one , thank you both for your help: I know I am dense

You don't even have to have more than one lens. A 100mm lens will have a different angle of view on every different format you stick behind it. A hundo is a pretty long lens on 16mm film but a very wide angle on 8x10 if there is even one that covers 8x10.
