Techart Pro has grown a lot since my original review and it is now widely avalibe (B&H Photo/Amazon/Adorama), but I haven’t seen a lot of great reviews of the adapter until now. Mirrorless Rumors did a great job reviewing the adapter in video form and Techart Pro seems to be endorsing the use of heavier lenses now in their latest promotional video. I look forward to seeing how this adapter continues to grow and I hope to see it on other camera systems soon.
