Hi,
Since it seems like there's quite a few different adapters out there, are any of them better or worse?
I can't tell if they're all the same and just branded differently, or if there are some of better quality.
New ones seem to pop up all the time on eBay...
It's for an Olympus E-PL1, if that matters.
Should I be spending $30 or $100?
Thanks for your advice!

I got mine from rainbowimaging off ebay, the marking on the lens doesn't line up to centre red dot on the camera (a little annoying).

I am not sure about infinity focus (not sure how to test it). I will try to find some time to use my manual lens (my pancake has been stuck on my GF1 for everyday use).

It is pretty secure overall though.

Infinity? Try a fill moon. Or a distant church steeple.
I have had good communication and experience with RJ. Off Ebay too.
