Mamiya TLR Lens Hood Question.

[marcmarc]

Hi Everyone,
So I picked a few Mamiya TLR bodies and some lenses. I am going to use the 55mm and an 80mm chrome version most often. I understand that the chrome lens has a different thread size then the newer black versions. Did Mamiya make lens hoods for these chrome versions? Whenever I look at lens hoods for sale online it doesn't specify if they are for the newer black lenses or the older chrome lenses. Will it be necessary to use a step up ring to use the same hood one would use for the black lenses? Also, there seems to be two kinds of hoods if I understand correctly, with one being an adjustable one that seems to cover both the viewing lens as well as the taking lens. This is the kind of hood I'd like to find but so far I've only seen the individual hoods that screw onto the taking lens. I suppose it would be nice to have a hood for the viewing lens as well as that might cut down on the amount of glare making its way to the ground glass, correct? It also seems that one can use generic hoods but that comes with the risk of vignetting with some of them so it just seems to make sense to try and get the factory made hoods. Thanks for any advice you can give me.
Regards,
Marc

I don't think there is a different filter size for the same lens depending on if it is the chrome or black version (although I am not for sure on that with the 80mm lens). But, there are different filter sizes between different lenses. My 65mm has a 49mm filter and my 135mm has a 46mm filter. I just ordered step-up rings to 52mm for both of them so I can use all the filters and hoods I already have.

Check out this page. There is a section on the lenses with all their filter threads (and even a section on lens hoods if I remember correctly). Hopefully it will help

There were some massive (as in large dimension) lens hoods for the early lenses. Basically two stacked boxes, and a clamp that fits around the lens barrel.

A lot of the later hoods were square with a tilt-able upper flap to minimize glade and reduce the intrusion into the viewing lens. They all clamp to the outside of the lens, so you will typically see them quoted as 42mm (for 40.5 filter thread lenses, 48 for 46, and something like 50mm for the 49mm threas (the rims are really thin).

Unless you have very thin filters, the hoods will not slide over them. Back when there were actual camera shops, I used to dive into the bargain bins looking for screw-in hoods with the right thread and angle. Regular hoods are not that much of a problem in the viewfinder - and better some decent lens hood that waiting around to find the ideal. All lens hoods are really too shallow (compendium types excepted).

These days it might be easier to calculate an ideal cone for the lens and 3D print a hood, epoxying it to a suitable empty filter ring.

if you look at page 43 of this document http://www.butkus.org/chinon/mamiya/mamiya_c330f_prof/mamiya_c330f_prof.htm you'll see that the chrome 80mm lens takes a 40.5 screw in filter and a 42mm slip on hood that Mamiya made specifically for this and the 105mm chrome lens. Search "butkus mamiya camera manuals" if the link doesn't work correctly, it will get you close.

I have a copy of all the black shutter lenses except the 250, and mostly have used the dedicated lens hoods for my TLR lenses, but in the past have been happy using a 46-49mm step up ring and a screw in metal hood on the 46mm lenses other than the 55. Unfortunately the Mamiya hood for the 55 is rather hard to find. As somebody mentioned, the Mamiya hoods are slip on. I use the normal 80mm hood on the 80/105/135, and the 65mm hood on the 65 and 180 super. Only the 65/180/250 lenses require thin ring filters that are almost impossible to find. Those lenses take 49mm filters. Standard filters fit normally, and the hoods usually fit over them for the lenses that take 46mm filters.

I think the two stacked boxes were earlier versions of what you see in the system chart. They were discontinued by 1982 when I first got one of these cameras.
