I might have to consider sourcing & purchasing the physical copy of the Sekor-Z Lenses repair manual which would be much more detailed diagrams etc... As there seems to be no digital version anywhere on the net that i have looked for. Like this: Mamiya-Sekor Z Lenses f/ Mamiya RZ67 Service, Repair & Parts Manual Reprint | eBay

Thanks for that info & links. Unfortunately the only 50mm lens in that manual has a different lens construction than what i have. My lens the "ULD" has an adjustable floating element. I am very confused as i have tried assembling the lens almost every possible way that makes any sense but when i put it on the camera & view through it the image is full of halos & soft focus areas is the best way to describe it. Is it possible that when i was cleaning the elements i rubbed off some special coating or something? :(

I need something like this but for 50mm ULD Does anybody have access to the Repair Manual for Sekor Z lenses that can send me a Photo or Scan?

Hi, i pulled apart the rear group of elements on my 50mm ULD to clean severe fungus growth. Stupidly i cant remember the order the elements go back together & its not very self explanatory as in the group can go back together many different ways. I need a diagram showing what order & orientation each element goes back together but nowhere on the net is there a diagram of any kind. Any advice appreciated! Thanks.

<p>I have been looking into the Mamiya RZ67 Lens System & have found that the Focal Flange Distance is 105mm. Although the RZ67 lenses do not have internal focusing, but instead Bellows Focusing which physically moves the entire lens further or closer to the film plane... So my question, is the Focal Flange Distance 105mm when the lenses are focused at infinity (the lens being closest to the film plane that the bellows allows) ???<br /> <br />Thanks in advance...</p>
