Considering selling my 17mm 2.8 pancake lens and getting the new Panasonic 20mm 1.7... If I ditched the Viewfinder (which I never use) and wide converter (which fits only on this lens), I'd break even at least...
Extremely torn on the issue.
Pros:
1. Faster f number means more shutter speed, and more "Bokeh" (background blur) when I want it
2. Panasonic lenses apparently have better Autofocus speed than Olympus ones
Cons:
1. It's much bigger than the Olympus lens
1a. doesn't look as cute and retro on the E-P1
1b. people might notice (be wary of having their picture taken) the camera more with the bigger lens on (however, right now I use mostly my huge old FD lenses and it hasn't been a problem so far)
2. I'd break up the lens kit, might hurt if I ever try to resell the camera.
Neutral:
1. The Olympus pancake lens already has some image quality quirks, so it probably wouldn't get much worse (and I'm getting better at fixing them)
2. I trust Panasonic to make good cameras - my last 3 point & shoots have been Lumixes and they were great.
What do you think?
