It doesn't always have to be "Limiteds". Here's a photo taken earlier this year with a 30-odd year old Pentacon 4/300 mm lens on my K10D. Yep, that's Pentacon, not Pentax! Meyer Görlitz for those old enough to remember. Commie stuff! Originally made for the Pentacon Six. Mounted on the K0D with an adapter straight from P6 to PK.
http://the-real-fotoralf.blogspot.com/2009/09/pentaxcon.html Built like the proverbial battleship and with a tripod collar that makes everything more recent look like toys, the optical performance isn't to be sniffed at either. The aperture has 23 blades! Bought on ebay for 67 euros, eight years ago. The two lower images are crops from the full frame. You can click on them to view them at 1:1 pixel scale. I've left the trace of CA in the upper one just to show how little there is. Photo taken at the Arcelor steel mill in Dunkirk, France. K10D, Pentacon 4/300 mm, f11, 1/20 sec. Enjoy. Ralf -- Ralf R.
