Olympus mZD 17 f2.8
A small gallery of the mZD 17 f2.8 pancake lens.
I find it quite reasonable, giving a 34mm equivalent focal length.
Not as good as the Panasonic 20 f1.7 lens. Having used this lens some more in recent times, I think I'll give the new Olympus 17 f1.8 a miss. This one is good enough for me.
