A few month ago I submitted a question to try have some feedback on the Congo Tele 500/9.5. Since none seemed to have used that lens, I will relate my first impressions after the first film test. <p> After some unsuccessful stories of trying to put my hand on a Nikkor T500 at a decent price, I finally grabbed a near new Congo at a used price. I was a bit anxious though as someone had suggested this was a piece of crap. Jeff at Badger was more than evasive when I asked him how it performed compared to the tenors from Fuji or Nikon but did not dissuade me. <p> So the very day it came on the post, it was mounted on my Technika for some test shots. I made some shots at close range (about four meters) and most at 100m to infinity. To have a comparison, I made the same shots with an Apo-Ronar 360. So here I have the Velvia's on my light table and I'm impressed! I dug out some 4x5 I made with a Nikkor T500 borrowed from a friend and, well, it appears to me that the Congo has nothing to want as far as resolving power and contrast are concerned. Under the 10x loupe, the 6x9 are as sharp as the Apo-Ronar's and maybe (but this is not a real lens test) sharper than the Nikkor's! The only flaw is a slight vignetting in the sky on a 4x5 but this should be easily corrected by mounting the lens on the right lensboard, as I used a lensboard that puts the lens off center. <p> For this is the concession to be made! The lens has only a tight coverage of the 4x5 format! No movements. But this is not too annoying for me for the kind of photography I want to use it for. As for other specs, the lens is a Tele-Xenar design on Copal 1, very light for a tele of this power: only 500g! Filter thread is 67 and length 15 cm. (yes a bit long compared to a Fujinon C 450! But when the bellows are not there...) It focusses infinity at 280 mm. It is multicoated, finish looks good. Perhaps a stain on the coating of an inner lens element, visible only under certain lighting (invisible when looking through the lens). Should not affect the quality at all and if this is the reason the price was so low, it is quite acceptable to me! Will have to work for a while to be sure the lens is really good but looks promising!
