That\'s exactly right. ASTAT-NEX worked with my OM and C/Y adapters, so I thought I\'d be fine. Should have looked more closely at the images of the adapter. It\'s just like the Leica R and EF-M with the release button preventing the adapter from fitting. There\'s nowhere on an APO SOnnar you can fit any lens collar I know of. And there\'s nowhere on the Teacart either (I really hope than any future model of techart has a tripod foot attachment)
The rainbow imaging adapter that the other poster mentioned seems to have a release tab that *might* allow a collar (if the adapter will even fit TechArt, which we just don\'t know) But it does bend back a bit over the area the collar might have to fit. In which case the tab might need to be straightened, which would put it at risk of breaking. Might be worth the small expenditure to experiment. But if the release tab broke later, while attached to a hugely expensive lens, it would be sad..
In my previous post I was actually going to express the same hope that Techart releases a version of the TAP with an Arca-compatible tripod foot. But that wouldn\'t solve your problem with the 925g Apo-Sonnar because the TAP would still be bearing the entire weight of the lens.
But... I\'ve just checked the B&H page for the Apo-Sonnar 135/2 ZF/2 and it gives the diameter of the lens as 84mm. However, that is probably the diameter of the ribbed focus ring section so the diameter of the rest of the lens barrel is going to be less than that. Hopefully, 82mm since that is the interior ring dimension for the Canon Tripod Mount Ring C for the for 70-300mm f/4.5-5.6 L IS. The OEM model is USD179.00 at B&H but you can get a Chinese copy for a fraction of that amount on eBay. Might be worth a try.
Here\'s a Photography Stack Exchange page that explains the various Canon tripod mount rings.
Wow thanks for that suggestion! I had briefly considered such solutions, and rejected them thinking the lens diameter was too large. I *think* I may have an old third party canon Tripod Mount C in my parts box!!!!!! [Edit: sadly I don\'t seem to have one. But they aren\'t expensive!]
