Hi all, So tonight I was out shooting with my P20...and I realized something. Its focusing abilities (especially in low light) are perfectly fine, despite the bad rap it gets in many places. (Pics to come later, I have a ton of stuff on the go right now, but thought I'd quickly post this). I was out shooting in very dark places. My most common setting tonight was ISO 3200, f1.7, 1/6th of a second. Not much light at all...and yet, the lens (mounted on an E-M5) nailed focus without fail every single time. Every time. Did it take a split second? Yes. Did it rack back and forth before deciding where focus was? Yes. But that all happened in less than a second and it delivered results without fail. I started wondering...just how much light was out there. Let's say a decent day outside would yield you an exposure of ISO 100, 1/500s, f5.6. That's a pretty average daytime setting. If I'm doing my math correctly, that's roughly 15 stops more than what I had today. Doing the math on that (2^15) tells us that I had 1/30,000th of the light. That's right...1/30,000. Now, my frames weren't uniformly dark, and I did have some things to focus on (apartment windows, etc) that certainly helped...but just to give you an idea of the OVERALL lighting conditions. I'm just posting this because from what I read about this lens online before buying it, I was almost discouraged based on its AF performance. But...I would say that for non-moving subjects, it's a fine performing lens under any circumstance. For moving, I'm not sure...since, I never shoot moving stuff. Also, I would say that this lens outperforms most DSLR lenses, certainly in its price range, as far as AF performance goes (and then you get the bonus of a very fast aperture, sharp optics and great colours in a tiny little package). That's all...samples to come whenever I get to them. Have a great day, everyone!
