Voigtlander Vitomatic IIa filter size

[Merlijn53]

Hi,
I have a Vitomatic IIa with Ultron lens.
According to the information I found, the filter size is 40,5mm.
I do have some filters of that size lying around, but none of them seems to fit. The filter thread seems undamaged.
Do I have to look for the original Voigtlander filters?

Where did you find the information?

Voigtländer had a great weakness for 40mm, so it may be that someone "measured" it and plumped for the nearest size they knew. I'm not saying that is the case: I'm just saying that I have some 40.5 filters that don't fit on at least one 40mm-filter Voigtländer lens I own.

Cheers,

R.

On the Bessamatic they have 40,5 push fit filter on the Vitoret LR and the Vito CSR I have 32mm push fit filter.

The vitomatic with Ultron might use the 40,5 or the 54 push fit which are used on the Septon for the Bessamatic.

This german site gives quite a lot of information on this camera: http://www.udo-afalter.de/voigtlaender/vitomatic/vitomaticiiaultron/index.php
Think I look out for one of the original filters.

Problem solved. There appeared to be an almost invisible dent in the filter ring.
The viewfinder needed to be cleaned and the shutter was sticky, so I sent it away for a full cla and they solved this as well.
