fast lenses Lexass
when choosing a fast lens would /p/ prefer:
a shorter focal length with a slower aperture or
a longer focal length with a faster aperture
for example: 35mm f/2 or 50mm f/1.4

both in the same price range

50mm. Works for almost anything, while portraits with 35mm = fail.

false.
i got a 35/2 for $150.
Plus, 35 on a 1.6 crop body = 56mm of awesome.
That's enough space to crop the portrait as you wish.

I bought one after my 50/1.8 shattered, and now I'm happy that I don't have to take 5 steps back to take a street scene.

Portraiture can be done effectively with any lens, ultra-wide to ultra-tele. Be creative.

35mm's suboptimal for portraiture on full frame. It's perfectly fine on a crop.

If you can afford the 50/1.4, I'd say get the 50/1.4.

I'd think that if you had a full frame, you'd actually buy a 85/1.8 or 85/1.4 for nikon? Anyways,>>122179is right. Who gives a fuck.
