Title: Filter caps for 95mm, NO front threads.
Post by: rollei8is on July 29, 2013, 06:00:09 am
I have a B&W 95mm circular polarizer with NO front threads.

I am looking for a PUSH on lens cap, any suggestions.

I spent four hours yesterday at B&H but NO success.

I do not mind any anything like Pringle box cover etc.

Help

How about an Optech hood hat of the appropriate size?

On my DP2 Merrill, e.g.  (In my case I use it to cover entire lens assembly with OEM hood attached.)

4" PVC or ABS pipe cap, then line inside with weather stripping/felt, etc to get snug fit (95mm = 3.74" ) . I did it with a Mamiya 645 200/2.8 APO that I wanted to cap with the hood in place. Works wonders. They have a lighter/thinner blue cap, a temp one IIRC for 4" ABS that works well.

Also Profoto lamp bodies are 4" outside diameter. Could possibly due same with a flat D1 monolight cap.

I've done the coffee can lid thing with a Nikon 200/2 VR and it works, but something harder like PVC or ABS, etc is far more puncture proof and more consistent with a 'normal' lens cap.

I like Conner's idea. I will try it out and let you know how it went.

My pleasure. Liek you, I wnet nts trying to find a pre-existing product that would work - and not cost way in excess of it's intrinsic value. Much too much time on B&H site. then walking through local hardware store, looked over and thought "I wonder". A couple of pieces of self-adhesive weather stripping later and done. Fit like a glove.

I used the blue temp ABS cap. I later thought the blue looked a little too DIY so just covered it in gaffer tape... I also drilled a small air pressure equilization (for lack of better term) hole in the center of the cap - as with the well-known coffee can lid & 200/2 VR solution.
