Hi
Is this just the focal reducer or is it a focal reducer and field flattener combined. the link seems to suggest it is an reducer only.
Does it produce an flat field to the corners of the frame of APS sized chips. Would be most interested if it is Red / FF.

Cheers
Jeff

As written on the 1st pic Jeff, Reducer & corrector & this is also written on the Bintel advert Lens photo aswell.
They just dont mention the word 'corrector' with this item anymore, this specific reducer for the ED80 scope is a corrector/flattener also.

Kind Rgrds ...
