I want to do some wide-field imaging with the Canon 200mm f/2L lens and the Canon 400mm f/4 DO II lens.
Does anyone here shoot with Canon telephoto lenses similar to these that have the 52mm drop-in filter holder?
If so, can you use the the 52mm IDAS Nebula Booster Filter in this holder? If not, what are the alternatives?
If the 52mm drop-in filter holder is not the solution, what about the gelatin filter holder approach?
Thanks in advance!
