I was filming today with my new Sanyang 85mm f1.4 lens using the Kipon adapter when I noticed a movement in shot that I was not expecting, on closer inspection it was found that the Kipon adapter is now failing.
I had been warned that this relatively cheap adapter would begin to cause problems but in less than three months of very light use is not commendable.
What happens is that the lens you are using has a rocking movement in other words you can physically move the lens up and down which should not happen. I accept that this was always a stop gap till the Birger EOS mount becomes available but a tad worrying.
I must admit to putting my 70-200mm f2.8 Canon lens on the adapter which will certainly have not helped though thats only been less than 5 times and the lens was supported.
My advice if you have the Kipon adapter is not to put any large heavy lens on this adapter and to use it sparingly.
