It seems like I'm the only person on earth that's interested in the performance of the new 20mm lens. Everyone is talking about the EP5 and the GX7... and that's all they talk about. I shot with the original v1 of the 20mm for 1 day on my OMD, immediately returned it the next day. The focusing speed is just ridiculous. I don't mind if it's a bit slow, but the lens would hunt for focus a lot. I'm a very experienced user of mirrorless cameras and using single AF point, I know where to point to help the camera's CD focus system. But to me, that speed was just unacceptable especially because it's hard to use manual focus override on the pan cake lens. Part of the appeal of the current generation of the m4/3 system is the faster AF speed compare to NEX and other APS-C systems. So I was not willing to deal with that. Anyways long story short. I got my v2 lens today from Amazon. It's quieter, but still the same slow performance in AF. If you are happy with the speed, good for you. But please don't be delusional about it and say it's normal. Because, it has to be the worst current generation lens in terms of AF speed. I had high hopes for this version, but it's going back in the box. Frankly this is quite a joke on Panasonic's part for releasing something with so little improvement. They could've had a real winner here.
