Hi, I bought this lens to mount on an Intrepid 4x5, the seller keep saying that is Copal 1 but the one i gor from Intrepid is just too loose. Anybody know the actual copal mount for this lens or how to measure to actually understand which lens board i would need? Many thanks for your help Filippo

No, i am doing this off camera, so not sure if the iris moves when i actually take pictures and yes, if i press it, it stop down indeed

Thank you Ben.... the lens is chrome but i don't feel comfortable on changing anything on my own....would just try to ask a local professional first. I noted that the more frames i shoot the less this problem happens and also i want to ask you something else, while i was playing with the 150 mm off the camera i noticed that if i was moving the f ring the iris was moving as well of course but after one full round from f 32 to f 4 it was not moving anymore and i had to click the stop down button to make it work again...is that normal?

Using a Hasselblad Carl Zeiss 150 mm 1 : 4 Sonnar Synchro-compur and i forgot to say that i tried with an 80mm too but i did not experience the same problem

Thank you very much for your help and time!

All right i just tested, no film in camera....camera is set at F11, i look in the viewfinder and is bright, i start to shoot, and the iris is fully open...after few shots i see the image in the view finder gets dark so i checked the iris and yes it is not open all the way anymore...so from what i understood i need to repair it requesting a CLA ? I see you are from NYC, nippon photo clinic is the place to go? one more question, when the view finder gets darker and the iris is not fully open...i suppose it means this effect the exposure when i shoot right? Thanks F

Hi Paul, what is a CLA? When you say to fire and to check the camera back, do you mean to remove the back and to check the curtains? Basically the first frame is clear in the viewfinder, then it gets dark for few frames and get back to normal.

Hi Ben, Basically when i start the roll, the image in the viewfinder is bright, then i shoot and the camera move the film to the second frame ready to be shot, at that point the image get darker...after few frames shot, it gets normal again. I don't change the aperture...will check know if it happens with a different lens too. Thanks for now.

Hi, I am playing with my Hasselblad ELM and i am using a A16 back for 6x4.5 images and a PM90 viewfinder. Inside the viewfinder the image is very bright as it should be but while shooting and getting ready for the next shot the image inside the view finder it gets darker...like if i pressed a depth of field button ( on a different camera ) or if i was closing the F. What it can be...a problem with the camera or am i missing something ? Please help. Thanks Filippo

Thank you very much!

hey there, i got a nice a16 back : ) so, do i need to add a mask too? I don't think so right? May be i just need a clear mask to see the actual crop when i frame the picture? Thanks again

Thanks, i wish i could : (

Thanks a lot! going to sell it to get an A16

Hello i just got this back, it is a A16 but i have a question. I thought that with this back i could shoot 16 and rectangular frames 6x4.5. I removed the dark slide sheet and i was expecting to see a rectangular frame, am i wrong? Do i need to add a mask or they just sold me a A12 for a A16? i am very confused...attaching image of the back. Thanks Filippo

It looks great, thanks a lot for sharing
