I've had my epm-1 for a few months with the 20mm on it. I really really like this lens. My only gripe is the focus hunting in low light. The images in low light turn out great its just the focusing that's a bummer. The 14mm is nice and small and apparently focus' faster but it isn't really a low light lens. My questions is...Is there a lens out there with the same physical size that doesnt have the low light focusing issues and has the same image quality? Looking to buy some more lenses...I'm thinking the best overall setup is the 20mm, 14mm, and 45mm. But just wondering what you guys think.
