    Old thread, I know. An easy, inexpensive hood for Mamiya, TLR's, is to use step-up rings.
    Step-up the 46mm and 49mm lenses, up to 52mm. There are several sellers on the *Bay
    that sell cheap 52mm hoods; $3.50-$6.00 USD.

    If you don't all ready have filters for this 52mm size, that's fine. Now when you use lenses with
    either 46mm or 49mm, you will only need one size filter to work on both lens sizes for the Mamiya TLR.
    There were some older chrome lenses for the Mamiya, TLR, that have an even smaller filter size. (40.5mm IIRC (?)
    Same procedure; step-up those lenses to 52mm, too.

    The 52mm step-up rings, and hoods can remain attached to your lenses, as there is very little shadow vignetting
    visible in the viewfinder through the viewing lens. Step-up rings can be found for around $2.50-$5.00 USD.

    The best hood for the Mamiya C 55 mm lens is the Mamiya one because it was computed to be most effective for the optic and it's hinged at the top to prevent the light bouncing off it in strong sunlight and obscuring the viewing lens without effecting the viewfinder screen,http://www.flickr.com/photos/35521202@N00/521118826/ other options without doubt are cheaper, but it's worth getting the right thing.

    Ben, I guess I'll just have to agree to dis-agree. I think my way is much easier to use/change, filters/polarizers.
    (Tah-mah-toe, To-may-toe)!<grin>
    But, at least we seem to agree on using a hood in the first place.

    I wasn't able to find any comments elsewhere on the 'net about inconsistent quality for the 55mm lens (other than the normal fungus problems). This was my search. Could you find me some posts/evidence of people discussing this problem because I'm on the lookout for a 55mm Mamiya Sekor for my C330f and I'd like to know what to be mindful of.

    Thanks
