I had a missing retaining ring for a Nikkor 10.5cm rangefinder lens one time and found something that would work to keep the rear element in the right place in the retaining ring bin at my local Ace Hardware store. It might be worth a trip to you local hardware store.

I was lucky to get one for a good price. If I'm ever able to cobble an adapter together, I will post the details here.

Thanks for the reply! I have the 100mm 2.8 and was wondering if it would be interesting on my Nikons as a portrait lens. I couldn't quite come up with a way to attach it. I do have the Mamiya extension tube set, but I could never figure out the thread size of the tubes that are threaded. But that might push me out beyond infinity anyway.

Orsetto, I was wondering what do you use to connect the Nikon K extension tube to the Mamiya press lens when you attach it to your Nikon DSLR? Thanks!

Hi all. After working normally for awhile, my Bronica EC now raises the mirror every time I wind it on to cock the shutter. Something in the mechanism must be out of sequence. Has anyone ever experienced this with their Bronica EC, S2, S etc,? It's like having mirror lock up on every shot. Maybe there is a simple fix.... Many thanks!

<p>Thanks for the advice guys. I was able to partially disassemble it from the mount. I was able to get to the helicals and apply a little solvent which did not really help. I can't disassemble it any further without taking the shutter out. I will try and warm up the lens with the sun and see if that helps. I was hoping it was dried up grease.</p>

<p>By the way, I'm located in the United States.</p>

<p>Hi all. I just acquired a nice Mamiya Press 250mm f5 lens. It's in great condition except for the focusing. It is completely jammed at infinity. Can anyone recommend someone that works on Mamiya press lenses? Many thanks!</p>

<p>Just a side note about the accessory lenses for the iiic is that they can all be used on the first Retina Reflex SLR (type 025). Since you focus through the lens on the slr, you just focus and shoot. I have a iiic, type 025 slr, and all the lenses. They are all fun to shoot with.</p>

<p>I actually called Nikon with just this question about a year ago when I was considering buying a used D600. They indicated that shutter sensor servicing would still be honored on a used D600. I would call to double check that it is still the case. I ended up buying a used D610 in the end though due to the price differential being fairly small. Best of luck! </p>

<p>Thank to everyone for their input. I appreciate it!</p>

<p>Here is a better photo. The red arrows point to where I am seeing the marks. It looks almost like the black paint has been rubbed off under thee edge of the front element. Thanks for any ideas!</p> <p> </p><div></div>

<p>Sorry, it was a quick cell phone photo I took last night. The two circular lines are under the outer edge of the glass near the rim. They run from about the 11 o'clock position to the 8 o'clock position in the photo. I will take a better photo tonight. I normally would not mind something like that, but I am planning on selling it and want to make sure I describe it well and am not passing on an issue.</p>
