I stand corrected on the link. I didn't think to look for a link to this thread on their downloads page, just on their main page and their FAQ page. Fred, I understand that you returned your TAP due to the wobble issue. Did your replacement develop the wobble too? If it's a flawed design, that's what one would expect. If so, we may get them replaced under warranty, but the replacements would likely then develop the same wobble unless the design flaw is corrected. As far as the likelihood of that, I agree with David's comment re saturation of a limited market. Interestingly, I think B & H, Amazon, and Adorama are all still selling the Techart Pro on their websites. I guess we'll see how all of this ultimately shakes out. I do enjoy using the TAP and I hope mine stays wobble-free for at least a while longer! ...Show more →
As I wrote a couple pages back, the 'lens carrier' is not properly supported towards the top section of the adapter. Eventually, that area will get some play and depending on usage, it will likely get worse. That's what happened with both of my adapters. The first didn't have any play for a while (I would say 5 months). Then the first signs of wobble started and it quickly became quite severe. (the one in the video)
Techart promptly replaced it and the new copy was perfect for a while but eventually developed the same issue. I still have it but do not use it much because it's wobbly.
For the record I only used light lenses on them. (ZM 35/1.4, ZM 50/1.5C, Leica 90/2.5 and ZM 85/4).
The adapter will work even with a severe wobble so it will never be unusable. However, mount parallelism is very important, and therefore I would not use it for critical work.
