 I bought this, knowing it was damaged, to see if it was repairable.  It has a fine ding in the focus ring, which can be turned only a few degrees - I fear that the focusing helix may have jumped a thread. I will have to see if I can dismantle this from the back. The beauty ring with its attached cone will not come out past the dent. |

 I partly dismantled the lens from the back, but there was no easy way to get at the focus ring. Instead, I beat out the dent using a wooden dowel, and moved it out far enough for the lens to focus. It looks a bit battered, still, but the glass is clean. A working lens! |

I also discovered why my pictures looked blue - I had the white balance on the Canon set to tungsten!

Good work, John, another M42 classic lives to fight another day!
Mildly bizarrely, I googled Oreston as I'd only vaguely heard of it, and got a load of links to Plymouth. Turns out that Oreston is a former village that has been subsumed into Plymouth.

Turns out that Oreston is a former village that has been subsumed into Plymouth. The Meyer Oreston was the middle quality standard lens for Praktica cameras, from the mid 1960s. It later became the Pentacon 50mm f1.8, and I believe it carried on into the bayonet lens Prakticas. I have a ton of them... The lower quality lens for Prakticas was the Meyer Domiplan, and the higher the Zeiss Pancolar. |

My Super TL had a Tessar f/2.8 The Tessar seems to have been replaced by the Oreston. |

The lower quality lens for Prakticas was the Meyer Domiplan, and the higher the Zeiss Pancolar. My first SLR (discontinued Exakta RTL1000 in 1974) came with a Zeiss Pancolar 50 mm F 1.8 (I still have some decent Kodachrome 64 slides taken with it). I recall the very smooth focus action and the unusually close focus. However, when I got a Pentax MX in 1980, its 50 mm F1.7 was much smaller and appeared to be of similar quality.
Good luck with the repair/rebuild - it looks like it's had a hard life. |

I have a Pancolar on my Exakta Varex IIb, and my RTL1000 has a Pentacon lens which is identical to the Oreston.
