Rear Lenss Cap for CV 21mm f/4?

[the.ronin]

Anyone know where to get or the part number for a rear lens cap for a Voigtlander 21mm f/4?

The rear lens cap I have for my Summicron 40mm and Elmar-C 90mm (part #14051) does not fit it.

I'm not sure what the problem is. Is this an M mount or LTM lens? I have an LTM version with an M adapter on it, and a standard M rear cap works on it.

If you are using the LTM version then...

HANSA makes a Leica L-Mount rear lens cap in 10, 14, & 17mm depth (silver & black)

In Japanese: ハンザ ライカLリヤキャップ17ミリ

if for the LTM version ( on M version any Leica M rear cap should fit ) and having to get it from Japan, you also could try Tokiwa camera, at least some 4 years ago they had the original Voigtlander, both rear and front caps, of the various Voigtlaender wide angles right in stock in their shop, weren't even expensive: ( in the link provided there is the "contact" email address, they speak English well ) http://www.tokiwa-camera.co.jp/index.html

Regarding rear caps for M mount lenses, my experience over the years is that those made out of harder plastic (Zeiss, Minolta, Voigtlander, genric Chinese ones) don't fit as tightly as those made by Leica, which are made of a bit softer plastic.

There also seems to be some very slight dimensional/tolerance differences in the rear mount of lenses (including leica lenses over the years) such that some lenses have a tighter fit of the rear cap than others.

I just bought two deep voigtlander caps, LTM, from the Head Bartender, who is a Voigtlander dealer

The correct part number is 10105
😀

Actually an R4A/M is more appropriate...

Or a Jupiter 12 rear cap does the trick for the LYM version.
