I just purchased a Sinar Sinaron 150mm f5.6 Digital lens in a Copal 0 shutter. It is coming from Seoul, South Korea, so I am not sure when it will arrive. It is the same design as the Rodenstock 150mm f5.6 Apo-Sironar Digital (it is the same lens with the Sinar Badge as confirmed by Rodenstock in Germany) lens in a Copal 0 shutter. The lens is to add to my Sony A7r and Cambo Actus system. The lens will replace my Rodenstock 150mm f5.6 Apo Sironar S lens which I will sell to help to pay for the lens.
I was able to finally test my Rodenstock 150mm f5.6 Apo Sironar S on my A7r with my Cambo Actimaus and the lens is quite sharp even on my A7r. I tried to test the lens the cheap way by getting the inexpensive Sony E mount extension tubes from China. Unfortunately when using 2 pair of these units I got a lot of glare/flare from the lens with this combination on my Cambo Actus. So I flocked one of the pair of Extension tubes. These have the 35mm rectangular cut out and unfortuanely even though I was able to redue or elimate the flare, with the flocking in place I am seeing vignetting in the corners of the image. So, I went back to just the standard bellows and as I expected there is insufficient bellows draw to focus the lens. So I rotated the front of the camera 180 degrees and reinserted the lens standard and found I had enough bellows to focus the lens from about 10 feet to infinity. But, I will have little or no ability to use tilt/shift, swings, and rise and fall of the camera with the lens.
I could have kept my Rodenstock 150mm Apo Sironat S but it has the older 5 Iris Blade Copal 1 shutter. I could purchase a newer 150mm lens with the 7 Iris blade Copal Shutter (like a Rodenstock 150mm Apo Sironar N) which would have the right scales and swapped the optical elements, but that would have cost about $300. So, I decided to use that money toward the newer Digital version of the lens.
If I can not get sufficient movements with the standard bellows with the Sinar 150mm Digital lens, I will purchase the Cambo Actus long Bellows in the future when I can better afford it.
If anyone is interested in my Rodenstock 150mm f5.6 Apo-Sironar S, let me know. It is in outstanding condition (probably mint) and this is one of the finest large format film lenses ever designed to cover 4\" X5\" film.
