Ever since I first started on this forum I have been reading about the 20mm f1.7. I have the Olympus 17mm and liked it, but eventually decided I really wanted a faster lens. It was time to try the 20mm. It arrived yesterday and I am blown away: E-P1    ---    20mm    f/1.8    1/400s    ISO 200 I took a walk around the neighborhood today . . . E-P1    ---    20mm    f/1.8    1/320s    ISO 200 Stopped at the church . . . E-P1    ---    20mm    f/1.7    1/200s    ISO 200 Went to get my mail . . . E-P1    ---    20mm    f/1.7    1/80s    ISO 320 Took a look around . . . E-P1    ---    20mm    f/1.8    1/800s    ISO 200 and saw some interesting things. E-P1    ---    20mm    f/1.7    1/250s    ISO 200 I love this lens!! E-P1    ---    20mm    f/1.7    1/1000s    ISO 200 I suspect this is all I'll be using on my E-P1 for a while.
