Originally posted by gokenin I was curious for the people that use prime lenses what is the usual gap between focal points that you have? I ask as I am wondering how large some collections have gotten with regards to primes. I was wondering also if people have multiple lenses of the same focal length i.e multiple 50's or if people have an auto and a manual lens of the same focal length? Just wondering if i was starting to get an advanced case of LBA to be honest

I would prefer to use primes exclusively, and have tried to keep focal length spacing to a minimum.

So, in primes I have all Pentax lenses:

14mm, 15mm, 17mm (fisheye), 20mm, 21mm, 24mm, 28mm (2), 31mm, 35mm (2) 40mm (2), 50mm (at least 8), 70mm, 77mm, 85mm, (2) 100mm (macro), 105mm, 150mm, 200mm, 300mm, 400mm, and 600mm.

In order to get wider than what Pentax makes in primes, I have the 10-17mm and 12-24mm.

I also have non Pentax 17mm, 58mm and 500mm.
