Thanks for the info, but the google couldn't help me to find the manual how to disassemble the Compur C00 shutter. Thus I posted the question here.

Hello,

I decided to return to the life my old Rolleicord I camera (okay, it's not the LF stuff, but here people know what Compur shutters are), but after testing speeds of its shutter I've...

Thank you all for your replies!



The dimensions of the lens elements of Ross No.3A in this book are the same as of my Ross lens.
But the difference of the focal length is still strange. I'll...

I already have found this ad somewhere in the Internet. But the scheme of the lens structure in this ad shows that the front and the back lens elements are equal in size. Mine ones have difference of...

Recently I aquired a big Ross Portrait lens. On the one side of the rack&pinion barrel there is a sign "Ross London 13766" and on the other side: "No. 3 A.P."

Do you know how to degauss them? I never heard of such procedure.

Thank you, but I made the cleaning by lighter fluid (but not oiling the gears) before I checked the speeds.

Jim, what surprises me is that I cannot find any screws on the aperture ring and on the exterior of the barrel on the whole. I guess that the barrel is molded thus it's impossible to disassemle it...

Here I attached the photos of the lens barrel. I removed all glass cells. The problem is that I don't see any ways how to disassemble the barrel in its middle to remove the iris without breaking it....

Okay, I'll think on your proposal :)

Seriously: how to remove this ring? I disassembled the lens but couldn't find any screws, etc. that let me remove it. From the front of the lens there is the...

Thanks for the idea! Unfortunately I'll have to add $40 for the shipping to USA and back. In total it'll cost me $90-115. Plus the cost of the lens itself as I got it $20. In total the lens will cost...

Hello friends,

Recently and by occasion I've acquired the old brass Taylor Hobson Cooke Anastigmat "Series III" 7 1/2 inches f/6.5 lens. The glass of the lens is in superior condition. In fact I...

Ole, if the Industar has the comparable optical performance to the Dagor, plus it has two advantages of one stop more and the coating, so why LF photographers...

Many thanks Joe! That what I was looking for! :)

Hello friends,
