Hello.

I want to buy filter for lens and wondering about filter size. Is it 37mm?

Thank you

105mm f3.6 uses Series 6 filters with a Series 6 holder that just slips on over the outside edge of the front element. The internal threads of the front element are not for filters.
Site search series 6 or series six and select all the terms to bring up all the threads about the filters and holders.

Measure the Outside Diameter of the front lens barrel then look for a series 6 holder of that size. The Series 6 adapters were available for lens diameters from 1 1/4 to 1 21/32. Use series V for smaller lens, series VII for larger.

The actual filter diameter is posted in this thread https://graflex.org/helpboard/viewtopic.php?t=2052

In a filter thread someone posted that a series VI retainer thread is 43mm.

The Ektar 105mm f3.7 takes a 38mm series VI slip on adapter, a very common size that may be hard to find.
