    There are many offers of 65mm for RB67, and some people say it's a great wide angle lens. It appears that there are 3 different lenses: a short sized one (35mm look like) , one that seems to end with a conical part and the long lens displayed as a current product on Mamiya website. Does anyone knows the difference in quality ? Are they all the same (I see that one is f4 versus f4.5 but that does not sy much) ?
    Thanks

    I use the RB mamiya-sekor C f4.5 lens on my RZ...always tripod mounted, and I can state that it is tack sharp and see no reason to buy a replacement. If you are going to be working off a tripod..why would you need a smaller lens or a faster lens? BUT...well, you understand.

    more precisions

    What is your 65mm the one with a conical end or the short one looking like a 35mm - see the 2 pictures

    I should preface my reply by admitting that I don't have this particular focal length. I do, however, have various K/L and 'C' - 37mm fish-eye, 50mm Sekor-C, 75mm shift, 90mm K/L, and 180mm K/L. Like you, I have this lens on my shopping list so here's my opinion - for what it's worth.

    The conical ended one I would avoid. It is the non-C Sekor, and does not have the multi-coating, and by reason of its age I would be nervous about the condition of the shutter.

    The one you describe as looking short would be the Sekor-C. The 65mm equivalent of the 50mm. It's multi-coated, will be younger, and I'm sure will give very good results. Given how cheaply you can pick up the K/L though, I would opt for that.

    Mine is the non-conical, short one and it is great.

    My (usual) advice would be to get the newest one that you can afford; even the new ones are inexpensive now- no real reason to pinch pennies unless you really need to. And get a hood as well.
