Hello everyone, Oly 45 is one of the first lenses I bought when I switched to micro 4/3. I use it regularly and I'm satisfied with it. I've got this silly idea from a few weeks now, to replace it with the Panasonic 42.5 f/1.7. The main idea is to get a stabilized lens to work better with my GM5 (I also have an E-M10 for which IBIS works fine with the O45). One other good things is the minimum focus distance, better on the P42.5. I tried to read reviews and comparisons and the conclusions seems to be that the P42.5 is also sharper wide open than the O45. I find my copy O45 to be quite soft wide open. However, it's totally usable at f/1.8 and renders quite well. One of the amin concerns I have about the P42.5 is the bokeh. On several examples, I found the bokeh quite busy with this lens. It may be due to the background and not the lens... hard to say. One other concerns is CA (purple fringing). I shoot in RAW so it's not corrected automatically whatever the body. O45 is not perfect on this matter, I wondered if the P42.5 would be better of worse... Has anybody already switched from Oly 45 to Panny 42.5 or the opposite?
