Discussion in 'Adapted Lenses' started by Speedliner, Mar 28, 2016.
purchased this from Adorama and received it last week. I was a bit leery after all the horror stories I read on various sites but went ahead and bought it anyway. I have not used it a whole lot yet but so far it works great. Autofocus is fast with and without a 1.4x extender. At times will hunt a bit but nothing major. I use the canon ef 300mm IS f4.0 and the canon ef 500mm f4.5 on an Olympus omd em1. The extender is a Tamron. The first time I put each lens on it the screen would go black from time to time. I would disconnect the lens each time and that worked. After doing that a few times it seems to have gone away. So no complaints (so far) with this and I am very happy.
