Guys, try the eye piece extender for Canon. It helps me to see the full frame on my 5Dm2 and focusing on my Leica R glasses with adaptor is a lot easier. It's a cheap $10 modification so no harm trying it. My cheap China AF confirmation chip is pretty fast even without stopping down. I got a 35 n 50 crons f2 and a 50 luv f1.4 _________________________________________________________________ Share your memories online with anyone you want. http://www.microsoft.com/singapore/windows/windowslive/products/photos-share.aspx?tab=1
