Re: 5DIII locks up with Kenko DGX Pro 1.4 and some lenses?

Thanks for the replies. I tried changing a variety of settings, including disabling AF-micro adjust and things such as staying in MF. None seem to resolve the problem.

The only lens that I have tried that the converter appears reliable with is the 70-300L. Even MF-only lenses such as the TS-E 17mm and non-Canon lenses such as the Sigma 50mm lock-up the camera when used with the converter. The problems seem to be specific to the 5DIII - older cameras appear to be ok.

I strongly recommend that anyone with the 5DIII avoid the Kenko DGX-Pro 300 until this gets resolved (maybe a future firmware update from Canon will change things). Meanwhile, I will look at lobotomising the adapter that I have.
