Pentacon /Orestegor 500 & 300mm

[pwsonline]

Being a nature (bird) photographer, and having no money for expensive Nikkor AF-glass, I discovered the appeal of MF hardware.
These babies even have manual aperture, took a while to get used to, but it's great fun, and good I.Q.

This is the Pentacon 500mm F5,6 (in mint condition):


And here is the Meyer Orestegor 300mm F4 (heavily used, but still OK):



Just see these aperture blades (present in both lenses)!


Thanks to the Pentacon mount-adapters I can use these on a Nikon DSLR without a M42 adapter with correction lens.

Cool !

I still want one of those 300mm Meyers. One day I'll get a cheap one.

The big guy is too expensive for me !

I too have a 300mm Meyers and love it. Still looking for a 500mm Orestegor though. I love watching the blades of the iris open and close on these. Smooth and nearly a perfect circle.

Hello everyone, I joined to ask this question...
I have one of the 300mm f4 Pentacon (Meyer Orestegor 300mm F4) with the M42 mount and I'd like to use it on my Pentax K200D. Now, I know I can get it to work with an M42-K adapter, but I have to press the manual stop-down button. Since I want to use this on a gunstock mount with electronic trigger, I'd have to use in in Aperture priority mode. The means that I'd have to ensure that the body contacts are shorted out.
Therefore, I'm looking for the Pentacon-Six mount for the 300mm f4, so I can use a P6 -> K mount adapter so I can rig it to short the contacts and have an easier to use, more secure connection to the camera body.
Does anyone have one of these mounts they could part with to help a guy out?
