Source of High Quality 27mm Filters...

[P. Lynn Miller]

I am looking for a source of very high quality 27mm B&W filters to use with my CV Collapsible Heliar 50mm f3.5. This size filter seems to be a rare commodity, where have other owners of this lens found filters?

I normally use B+W or Heliopan filters, but neither of them make a selection of B&W filters. Looking specifically for a yellow, green, orange, red and blue.

Any recommendations would be appreciated...

I have a set of 4 Canon bw filters:Red, orange, green and yellow. Mount is made of solid chrome, very thin, flat and threaded on one side only. All mint, except red filter that has two very, very faint concentric marks that do not impair image quality. Each one in its original Canon engraved 27mm plastic case. US$ 65.00 plus shipping from New York. For Pay Pal, please add 3%. You may email me: jubano@earthlink.net
PS: Thank you for the valuable comments and photographs that helped me choose the 28/2 Ultron.

Does this means that the hood and cap can no longer be used when these filters are used? Any alternatives for caps then?

Cheers,

Since I am not familiar with the Heliar lens, I cannot comment. I obtained this filter set as part of other unrelated equipment. All I know is that they are beautifully made (light yet solid chrome rim) and in great condition.
