If so, what are your thoughts/preferences? I would like a 40mm FF equivalent compact prime, and I happen to have a Fuji body and an Olympus body, so either Fujifilm 27mm f/2.8 or Panasonic 20mm f/1.7 II would work. I'm aware of the differences in their basic specifications and the benefit of having IBIS with my Olympus body and one lens being "brighter" than the other, but I'm more curious about the rendering differences between the two lenses. I don't know if both are a "wash" in terms of optical performance or if there's a preference. (Oh and both are approximately the same price for the units I'm looking at). I know neither one is an AF speed demon, and the Fuji lens is chattery/louder in operation--I'm not looking to shoot video with either lens; only a portable solution for stills for daily carrying. Could owners of both of these lenses (at the same time or at different times) please chime on? Thank you!
