A question of optics
6 months ago
When I look at the view from old 35mm Nikon FG film camera with an 85mm lens, it is about the same as the view on my Olympus XZ-1 with the zoom lens at full tele, or 112mm,
Practically, it doesn't matter -- I can use the XZ-1 as a monochrome viewfinder for the FG without any problems... I don't need an exact preview match.
But I'm curious. 112 minus 85 leaves 27mm missing... more than differences caused by the FG's 93% viewfinder. What's going on?
I don't know optics. Am I incorrect to expect close angle-of-view similarity between two lenses that are very different in physical size? If so, why?
Thanks in advance for thinking about this...
