Frequently asked questions
What's a rear filter holder good for?
On ultra-wide lenses, front-mounted filters can cause vignetting or mechanical interference with the lens hood. A rear filter holder lets you drop in gelatin or glass filters behind the rear lens element, avoiding those issues. Less common on modern lenses but useful on vintage wides.
