Originally posted by aurele I have a 28mm, 35mm 50mm, and i have to say that 35mm is a bit frustrating because it's wide but not enought or it doesn't bring you visually close enought (not enought zoom effect, and not wide enought).
I notice interesting progressions in my favorite focal-length lenses. I'll start with the Zenitar 16/2.8 which defishes to about 12mm. Next is a 24mm, twice 12mm. Next is a 50mm, ~twice 24mm. Next is 100mm, twice that. And next is 200mm, twice that. A slightly different progression goes 16-28-55-110-180mm, again almost doubling, but fitted to taste. The next progression goes by ~1.5x not 2x: 16-24-37-55-85-135-200mm. Do those of us with several lenses each have our own favourite progressions of focal lengths?
As for 35mm on APS-C: Like you, it's not my favorite. But I didn't really like its 135/FF 'equivalent' of 50-55mm either -- too long for normal view, too short for tele. My most-used primes now on my K20D are 16-28-(50-55)-(85-105). 28mm seems to capture a more natural view than 35mm, and 50-55mm are better for more concentration on a subject. But these aare for environments rich in nearby targets. If subjects are far away, it's the 500/8 mirror!

SOME primes are built that way. Some are just cheap.
My F35-70/3.5-4.5 does rather better at 50mm than does my Meyer Domiplan 50/2.8. And the Domi cost more!
Quote: I use a film body and a digital body, and all my lense fit correctly without vignetting on each body (exempt the kit lense 18-55mm.)
The DA10-17 vignettes rather severely on a FF body, but that's mostly because of the built-in hood-let. If I could remove the hood without trashing the lens, I'd have a WIDE fisheye! It would have FOV equivalent to 6.5-11mm on FF! Yow!
ObTopic:
The 'best' walkaround lens depends on where you walk, and how much you want to spend. My basic lens is the DA18-250, backed by the Tamron 10-24; all others are specialty tools. If I had the money and was in the right places, an f/2.8 around 16-135mm would be great. It all depends...
