View Full Version : An Old Master with a New Trick

After going through my share of cameras, I decided some time ago that I needed to find an 8x10 that I might hopefully stick with the rest of my camera-toting days. But there are a lot of cameras to choose from. And there's no such thing as a perfect camera. Each one is its own set of compromises.

Based on earlier experience, I'm very fond of the Kodak Master, aka Kodak Master View or KMV. The ergonomics of the Master suit me. It sets up quickly. The front extensions are simple slide-and-lock. It uses rear focus (which I prefer) with rack & pinion gearing. Movements are adequate. In fact, this camera has very generous front rise at 4 1/2 inches. Weight is reasonable (about like a Deardorff). And it has enough vintage-ness to it to keep the romantic in me happy.

The Kodak Master has a few drawbacks as any camera does. Most objectionably it uses those odd, difficult-to-find lens boards. Modern CNC replacement lens boards are available, but they're very expensive. And besides, I've pretty much standardized on Sinar and Technika lens boards. So I decided to look into having a KMV modified to accept Sinar lens boards.

But I wanted more. I wanted this camera to not only take Sinar lens boards, but to take a Sinar/Copal shutter as well. And I wanted the shutter to mount behind the front standard as it does on the Sinar camera. This would require not only fabrication of new parts, but a new bellows as well. The bellows would have to utilize a Sinar bellows frame at the front to be compatible with the shutter.

After some hunting around I found a clean KMV with a tired bellows that needed to be replaced anyway. As it turns out, the KMV is a really good camera for what I wanted. The design and the dimensions of the front standard allow for a Sinar shutter to mount behind the standard so that it does not interfere with the operation of the standard. And because the front standard uses base tilt, the shutter doesn't inhibit that, either.

The metal parts were very straightforward. The original Master uses a lens panel which rides in a groove in the front standard. This panel allows the lensboard to attach to the front and the bellows to the rear. A new panel was made which was slightly thicker to accommodate the deeper light trap design of the Sinar board. The new panel is a direct replacement for the original.

Wanting to retain as much of the character of the original camera as possible and all the function, the bellows hooks were transplanted from the original. But the lens board retaining hardware, intended for those thin-lipped Kodak boards, did not provide a secure grip on the Sinar boards (which have a slightly chamfered front edge). So new retaining hardware was made. And a new bellows was ordered from Custom Bellows utilizing the Kodak rear bellows frame and a Sinar front bellows frame.

The result is a solid, functional 8x10 camera with enough vintage appeal to keep the romantic in me happy. My Sinar-mounted lenses fit directly. Technika-mounted lenses fit with an adapter board. Unmounted lenses can sit in a lens chuck. And barrel lenses now have a reliable, accurate shutter. Even some lenses with funky shutters now have an accurate shutter.

The Kodak Master isn't the lightest 8x10 around. It's roughly the same weight as an 8x10 Deardorff. And the shutter adds weight to the kit. But the camera works in the normal fashion without the shutter, of course. It's still a KMV, after all. The camera folds just as before, but with the shutter removed; it won't fold up inside the camera.

Overall the camera is exactly as I hoped it would be. It's very versatile. The biggest problem is probably going to be deciding which lenses to leave at home.

I think you just made it! :cool:

Will,

It's a beauty! The loud majesty of that fat Cooke lens matches the quiet elegance of the Master perfectly!

Dear OP: will you build one for me? :D

I modified my KMV some years ago to take standard 6x6 lensboards, so my boards all fit on my (8x10) KMV, 2D, B&J, and my (5x7) Rembrandt and Noba. But I think with the addition of that shutter, you've taken it a significant step farther! Congratulations on a great creation, and use it well! :)

I appreciate very much the many positive remarks!

Kodak Master with both 8x10 and 5x7 backs: $1600. Machine work: $500. New bellows: $350.
Ability to use Cookes, Heliars, Darlots, Petzvals and a multitude of other lenses on a field camera with a reliable shutter: priceless.

Outstanding modification Will. I especially like that you can effortlessly remove the sinar shutter to use lenses already mounted in operational shutters. Great flexibility; ingenious. Congrats!

That's my old camera- you can see the bellows patched with 'liquid electrical tape' in the first photo. Brilliant concept, Will, and great execution. Best of luck with it!

No kidding! Thanks for the detailed photos. I almost purchased a KMV last year, and now, I'm kicking myself!

I'm not familiar with Sinar system so I'm sorry for my silly question, but that rear of the front standard (which is able to attach either bellows only or the shutter) was a part of Sinar front standard or you made it?

"A new panel was made which was slightly thicker to accommodate the deeper light trap design of the Sinar board. The new panel is a direct replacement for the original."
From the original post.
Will designed it and had it made at a machine shop.

Will, I want to restart this thread.

Can you post the lost pictures or send them to me?

I also like the smooth rear focus.

Thx!
