Does anyone have a good idea of which lens hoods work for the various 645 lenses. The lens database lists proper hoods for some of my lenses, but I don't think they are really available. When I go to B&H or Adorama, they have a few suggestions, but I don't know if they are appropriate.

I use the following:

- 35mm manual 645 lens with a 77mm thread
- 55mm manual 645 lens with 58mm thread
- 75mm autofocus 645 AF lens with 58mm thread

Just go to B&H and search 77mm hood, and you get a number of choices, rubber, metal, plastic, circular, petal. Obviously, you don't want blockage of the image.

I found an old Vivitar branded metal hood for my 75, works fine. In general, the hard ones are the wide angles, as with a telephoto you benefit from a longer hood but one made for a normal focal length will already help.

There are some lens hoods on ebay right now. One for the A 35mm (Item number: 310256530973) and some for the A 75mm (one is Item number: 220676417376).

Whoa EUR33 plus 15 shipping for a rubber hood feels a little bit steep...

It is the original Pentax hood.

Last time it was available in Canada the dealer net was over $60

Oddly, I just saw one for the 55mm, the RH-B 58mm, but it is advertised for the 75mm (erroneously I think). Here is the eBay no. : 310256529506. The 75mm is the RH-A 58mm. I also found another one for the 75mm: 170501770297 but way more expensive.

Yet the one for the 35mm above has gone (thanks Yurihuta...) as I was dissatisfied with my metal one. Steep price indeed, but that's not unusual, strangely, with the accessories—you only want one when you've got the item that goes with it, and then you really want one.

75mm: lnhm58 - Adorama.com

Does this help?

I used to have the A 35mm hood and it was pretty much useless as being too big and flopppy. Instead I hot glued a medium sized plastic bowl onto a 77mm Cokin adapter (using lots of glue), and cut it out for a rectangular photo. I'll post a pic if I can find it but am now using the FA 35mm with a proper hood that I had to buy from Japan.

The 55mm takes a RH-B-58 while the 75mm takes a RH-A-58 hood. But a generic will work fine for these non-wide angle lens. I wouldn't get one of those multiangle hoods for 55mm and 75mm because with the viewfinder showing only 89% or so you might end up with some vignetting on the neg or trans.
