I'm looking for a slightly wide (approximately 28 or 35 in 35mm equivalent) as a standard, walk-around lens to use on my Panasonic G5. I don't want to spend too much (I would absolutely love to get the new Panasonic/Leica 15mm, but it is way out of my budget at this time). The Panasonic 14mm 2.5 specs look interesting on paper, and the price is within my current budget as well. I understand that 2.8 might not be the absolute best option for low light work, but I'm used to using prime lenses at this slower aperture. Back in the "old film days" I used to carry a Nikon F3 with a Nikkor 35mm 2.0 AIS as my daily walk-around camera. On my DX format (Nikon D200), I discovered I like using a 24mm 2.8 as a daily, walk-around kit. In terms of field of view these lenses are roughly about the same imo. What are your thoughts on the Panasonic 14mm 2.5? I noticed there is an Olympus 17mm 2.8 in the same price range. Any major differences other than 3mm?
