Hello photogs!


Recently I purchased off ebay an old Mamiya rubber hood, 67mm.


It is great. I say rubber, but it is reinforced with metal in the inner ring as well as the outer ring, that can even accept an additional, larger filter (duplicate thread). 


Unfortunately, these hoods are (were) not marked with the filter thread diameter (e.g. 67mm) but with the indication of the Mamiya lenses that the hood would fit. Since I am not familiar with the Mamiya 6x7 lenses, often I cannot pick from ebay listing the right Mamiya hood for my lenses.


So, a first question I would like to ask you is: do you know a list of the old Mamiya 6x7 lenses with the indication of the filter thread diameter?


However, I titled this message "95mm" - why?


Well, I am looking for a wide-angle hood (not petal shaped) for a lens that I have just purchased which has this rather unusual filter thread. I would like to ask you a list of lenses that you know to have this front filter thread diameter. In this way, perhaps, looking at the accessories for that lens, I could come with something for my lens (which, by the way, is a Zenzanon PS 40mm f/4). Perhaps even a Mamiya one or a push-fit one.


Thanks!


Marco

The Zenzanon PS 40mm f/4 has a diagonal angle of vision of about 90 degrees on 6x6cm , and a lens hood on this format would cause vignetting. I own a similar lens and use a compendium, which also allows the use of gel filters, but it is cumbersome. So I did try a lens hood once, but only once. However, if you are using this lens on a smaller format - 6x4,5cm- this problem would be reduced/eliminated.


Sorry this does not answer your question - it was just a thought.

Thank you anyway, Graeme. No, I'd use it on 6x6-


Whiteway, this document is gorgeous Besides the filter thread information. I really like it - you know, I am into "old" cameras. Would you know how to access the rest of the "SourceBookProPhoto" book? Is there an index on BH site?

It's not obvious how to do that. You could try contacting the site.
