I had commented about the Color Ultron AR 1.4/55 with Rollei QBM mount, it's a Rolleinar/Mamiya labeled Color Ultron for the Voigtländer Rollei QBM cameras, they are a multicoated copy from the CZ Planar 1.4/55 for the Contarex. The official data on this lens says it has a 49mm filter thread; last week I took the first photograph using it on the VSL3 -E without lens hood (I hate to take a photo without lens hood), it happened because I had a 49mm lens hood in my bag and it was small for the lens, there is an error in the lens specs, the filter thread is 52mm, I also have a 52mm lens hood and it fitted perfectly, my lens has the original lens cap with the word "Voigtländer", a different lens ring is not the problem. This was that first photograph without lens hood, taken a misty morning, Kodak ISO 400 Ultramax film: http://www.flickr.com/photos/itarfoto/6956286672/in/photostream This one was taken with the Rolleinar 2.8/150, it has a built-in lens hood: http://www.flickr.com/photos/itarfoto/7102354573/in/photostream/ Carlos --- Rollei List - Post to rollei_list@xxxxxxxxxxxxx - Subscribe at rollei_list-request@xxxxxxxxxxxxx with 'subscribe' in the subject field OR by logging into www.freelists.org - Unsubscribe at rollei_list-request@xxxxxxxxxxxxx with 'unsubscribe' in the subject field OR by logging into www.freelists.org - Online, searchable archives are available at //www.freelists.org/archives/rollei_list
