Fastest Speed of all 4x5/9x12 Sinar Norma

https://live.staticflickr.com/65535/...7eaa8211_z.jpgFastest Speed of All Sinar Norma Three Good Pairs 1 by Nokton48, on Flickr

After searching around and configuring what I can right now, I have come up with three perfect identical lens pairs for the Fastest Norma twin lens camera. On the left, are absolutely identical Schneider 150mm f5.6 chrome Componons. In the middle, two nearly identical (will do ok) 240mm f4.5 Schneider chrome Xenars. The viewing lens only works wide open, the iris is not working. But OK for viewing. I still have to plug the mickey mouse automation holes with aluminum filler. And on the far right, a perfectly matching pair of forward mounted Schneider 240mm f5.6 chrome Symmars. The taking lens is a Sinar Symmar, and have direct operating mickey mouse aperture mechanism (least amount of automation aperture board). It will take several hours of metal cutting to buzz down the flange diameter, and enlarge the hole size in the top hat. Then all will fit and I will have three nice workable pairs for this camera

that's what i was going to suggest, except you start with the camera raised to frame the shot and drop it before confirming focus and taking the shot.

Right, THANK YOU I wonder if anybody who used this in the 60s vintage studios back then is familiar how to operate with it. But thanks for all suggestions and interest :)

Richard Avedon used the automated Norma stuff for some of his commercial 8x10 work. Motion being captured in an extremely acute way, that appeals to me. Back then the advantages of automation were obvious and Avedon was easily talked into it I'll bet. I find it fun to get this stuff fully put together and fully operating as originally intended. That to me is a hoot for sure

Matching 240mm Sinar Symmars in matching forward mounted lensboards. Clamping mechanism above adds rigidity, could use some short rods, across the top metric stock from McMaster Carr will do the job. Twin Sinar Norma Bag Bellows on back with Sinar Norma Monocular Viewers works great. More matched pairs are coming in, 150 180 210 300 chrome Componons, 250mm H5.8 Rodenstock Imagon barrel pair, So I will be well prepared for high speed 4x5 portraiture and tabletop stuff.

Today a matching pair of these 300mm Componons came in, I mounted them quickly into identical boards. The view through the top lens is from a higher viewpoint, that is what I want. I can get matching views as close as possible, something I think I csn get used to with more practice. I like this camera, it's so different from anything I have used. 300mm is 2X on 4x5 and is about as long as you can go I have read regarding the Gowlandflex. Sinar says this camera will take any focal length.

Here the fastest Norma is set up to provide identical views, with the identical 300mm Componons. Top and bottom views are similar, of course the top taking lens has a higher viewpoint, so I am shooting slightly slightly down versus the view lens. Desirable for high speed B&W portraiture

Perhaps parallax is corrected with longer lenses to reasonable distorsion

Tin Can/All,

I've used TLR Mamiyas for weddings and portraits many years ago, I once had every model in the line at one time, and all the lenses and attachments. My fave was the venerable Mamiyaflex C2 but also loved the C33. It's taking some time to get my head around what Sinar was doing here, but after kicking the tires a bit I really do like this new rig a lot. It's different from the Gowland in that taking lens is on top, viewing on the bottom. Sure there has to be parallax, but the views can be made to be approximately similar by using the rise/fall moves on the Norma. Viewpoints without question have to be different through both lenses, but this is something I can get used to. I'm sure raising the top viewing lens on the Gowland up, to get approximate same framing, changes the viewpoint also between the two lenses, I'm sure through experience Gowland got this exactly where he wanted it. It is the same but different with Norma. The closer you move in, and the longer the lenses, the more space between them required for for approximate similar framing, although there is the viewpoint difference which increases as you move in. I could also reverse the lens sets, with the taking lens on the bottom (like the Gowland) but I think I prefer this configuration for my uses. I have another Norma Shutter coming from Germany, to dedicate to this camera, as well as three new Norma Rail Clamps, I'm going double clamp with this camera for brick house stability and easy balance with this new rig on my monster Plaubel Profia camera stand.

Glenn Evans in Chicago has configured a similar Sinar Norma TLR camera.

I admire your tenacity and goal of perfection

I use C2 or C3 Mamiya and prefer them to newer

Your Norma TLR gives me DIY ideas

IF they occur, I will post elsewhere

I read all your posts

Thanks Tin Can. Here I am in my covid bubble, happily tinkering with my old technical cameras, trying to get them to operate as intended. And having a blast doing it! :)

Here's the fastest speed Sinar Norma set up with twin 150mm f5.6 chrome Componons. Basically to use this camera, you adjust either front or back tilt, so that both screens are in sharp and in similar plane of focus. Rise and fall will produce nearly identical views during final framing and is quite accurate. Today I exposed four sheets of Fuji HRU XRay film, once with the top lens, and a second with the bottom 150mm lens pair. I then repeated the process with the 300mm f5.6 chrome Componon pair, again shooting with the top and bottom lenses to see the difference in prints. The negs look just great, and are drying right now. I will post B&W prints in the next few days. Entirely successful test as far as I can tell so far :)

It took four original Sinar Norma Bag Bellows to put this thing together. Notice also I have two Norma Base Rail Clamps attached now, for added stability.
