Thanks Scho,
Slippery indeed. I ended up returning it, it was a tough choice. In may ways, the 24-85 represented my first lustful feelings towards exotic alt glass. Before mirrorless, I watched somewhat amazed at what folks went through to get their lenses converted by Conorus. If I had found what appeared to be a reliable, manual focus adapter for a sane price, I would have stuck with it. If I had a waiting stable of CN glass, I would have probably gone in with the Fringer. That was a close brush with the lovely CN, sad that it was not to be.
