Filter use on 135 4.7 Xenar

[Paul Palka]

Hi, I recently purchased a Crown Graphic and a Xenar 135mm f/4.7 lens. How can i use filters on this lens? It has theads but i heard they are non standard and i couldn't just screw in a filter... Do I need an adpter or something? Any help i s greatly appreciated, Thanks

A 42mm slip-on adapter for series VI filters fits. Since it has metric threads, unlike the Ektar and Optar lenses, I believe that a screw-in filter may work, probably 39mm or 40.5mm.

It should take a 40.5 mm filter, readily available at B&H and most other large suppliers.

The 135 Xenar takes a 40.5mm filter. Filters of this size are often hard to find and often more expensive than regular sized filters (49,52,55, etc.)To work around this situation I got a 40.5-49mm stepping ring (about $12)on which I mount readily-available 49mm filters. It also allows me to use filters on my 90/6.8 Angulon, a tiny lens which also has a 40.5mm filter size. I hope this helps.
