Distortion based on Focal Length or FOV??
Mar 23, 2014

I've been struggling to find one prime focal length for people shots in dimly lit environment (birthday at a restaurant, etc) because obviously people's faces do look better with little longer length lens but group and ambient shots require wider lens.

One thing then came into the curious mind, let's say that

17mm olympus lens on m43 = 34mm FOV

18mm fuji lens APS-C = 27mm FOV

24mm Sony full frame obviously = 24mm FOV

Which number affects the natural distortion of people's faces, the lens focal length or the FOV?

Does this mean that using 24mm full frame will get better perspective while getting wider scene??

Forgive me if I have't used the correct terminology in the question, but I hope the question on the concept is clear.

Thanks!
