Schneider-Kreuznach Retina-Curtagon 50mm f/2.8 lens?

Proof it exists. Schneider Kreuznach Retina-Curtagon 50mm f/2.8 https://www.flickr.com/photos/27748767@N08/18171512658/in/dateposted-public/ Bizzybody (talk) 21:04, 1 June 2015 (UTC)[reply]

Your photo shows a Schneider-Kreuznach Retina-Curtagon 35mm f/2.8. This undoubtly exists and is documented all over the place. But for the second time you added a "Schneider Kreuznach Retina-Curtagon 50mm f/2.8" to the list of lenses, which is not listed anywhere else. Hence my question.

Anyway, it seems not to exist. --Matthiaspaul (talk) 14:06, 2 June 2015 (UTC)[reply]

Rodenstock Retina-Heligon or Retina-Ysarex 50mm f/1.9?

Here's another one: Various sources in the net document either a Rodenstock Retina-Heligon 50mm f/1.9 or a Retina-Ysarex 50mm f/1.9. While it is possible, that the lens formula (Heligon and Ysarex indicate the basic arrangement) was changed over the years of production (if not by the labelling it should be possible to determine by counting the number of reflections in the lens), it is more likely that this is the result of some kind of "copy and paste" error by someone long ago and than carried over in other lens lists. Needs to be sorted out. --Matthiaspaul (talk) 14:06, 2 June 2015 (UTC)[reply]

Found a photo of a Rodenstock Retina-Heligon 50mm f/1.9 in DKL-mount, so this one exists for sure. Still unsure about the Rodenstock Retina-Ysarex 50mm f/1.9. --Matthiaspaul (talk) 02:17, 3 June 2015 (UTC)[reply]

Lack of understanding?

It seems that many sections have been edited by people who don't understand the Retina cameras and the difference between the viewfinders and rangefinder models. Both types were offered in parallel from the 1930s, though the first several models were strictly viewfinders. Only the last 2 generations of rangefinder cameras used the convertible lens system IIc, IIC, IIIc, and IIIC (III had metering - Big C had advanced features). The Ib and IB were the last of the folding viewfinder models; ironically, the convertible lenses can be installed on the Ib/IB camera-mount, but won't function properly without a rangefinder.

Only the first Retina Reflex shared this system, and beginning with the Reflex S lenses were fully interchangeable. This was never offered on the folding models.

Also the reference to the Contaflex having a similar exchangeable front cell beginning in 1956 was wrong. All Contaflex cameras from the Contaflex I of 1953 had this feature. East German Contax SLRs used the M42 screw mount, but West Germans Zeiss-Ikon didn't offer fully interchangeable lenses on an SLR until the Contarex of 1958/59 (introduced/delivered).--Kevin Murray (talk) 14:20, 14 April 2020 (UTC)[reply]
