What is the reason to reverse a Raynox lens.

Alan

Blew out the Sony A7Rii sensor and think it's ok now

Al

Thanks for that JH

Alan

Appreciate that Rik I can understand the Nikon D300 and the Sony A7s being dusty but the A7Rii is brand new,,,,maybe Chinese dust on the sensor, I'll clean them and have another go.

A 52 to 43 would be more use for reversing if both threads were female.
Then the 52 could take a flat objective adapter.

Chris would a flat adapter be better than a cone.

Strange you posted this Chris, about a week ago I asked him to make these for me and 2 of each are on their way to me. Hi Alan. Your adapters are finished: http://www.rafcamera.com/en/adapter-m42x1f-10mm http://www.rafcamera.com/en/sdr-m52x0-75-to-m43x0-75 http://www.rafcamera.com/en/adapter-m43x0-7...

I have 3 of them and in the process of setting up a new setup using them.
