I do apologize for asking so many weird questions.
Hi Aelindgard,
As a varifocal going from 4mm to 10mm, this lens would provide between a 22mm EQ FOV at 4mm to 55mm EQ FOV at 10mm and everything in between, so it would be considered to have a wide to normal range. There are different conventions that 35mm photographers have adhered to, so it really depends on who's opinion that you ask, but many will say that anything shorter than 35mm is a wide angle, 35-60mm is a normal, and anything over 60 is a telephoto.
In angles of view, for a 35mm format camera, 22MM gives @ 79° horizontally in the frame, and 55mm gives @32°. A a subject distance of 10 feet, this would give you approximate coverage of @ 16.3 feet wide at 22mm and @ 6.5 feet wide at 55mm.
There are not many photography related questions that are weird enough to feel compelled to apologize for asking here, so don't worry. . . we've all been there at some time. . .
