As described, fitted perfectly to an older D3100, which then connected to the reducer/flattener on an ED80 Pro.

It's one of those must-have accessories if you want to couple your DSLR to a scope. This is well-made and does the job for a great price, and the packing and service wass, of course, FLO's usual high standard.

I purchased this to give the correct 55mm spacing for my SW ed80 flattener/reducer (also from Flo) Fits my eos very snugly unlike the cheaper eos adapter bought elswhere. From email query to arrival the servive from Flo was quick and professional. Very happy.

I use this to connect Canon EOS Camera to the William Optics Z61 field flattener. Nice tight fit, no movement
