Hi Dirk,

Inspired by your great conversions I've sourced a Zeiss Nettar and a 47 SA and have begun building. Looking at the photos of your camera it looks like the lens is mounted in the center of the new lens board. The Nettar's film gate is offset down effectively giving you front rise on the lens if the lens is in fact centered on the front. If this is right is it intentional or just how the helical needs to fit? It would seem to me with such a wide lens some front rise is not a bad thing to avoid excessive foreground.

How did you mount the front lens panel to the camera body? I'm thinking of using epoxy to glue it in. If your are not wanting to give away all your secrets, I understand.

Cheers
Rick

SONY DSC by Nokton48, on Flickr

This is the handheld camera I used to photograph the digital tree photo just posted here. Great for testing and checking lenses, Makiflex Automatic #1 has the Makiflex Auto Iris 150mm Schneider Symmar. I have only seen this lens offered in Europe after decades of looking around. Anyways cock the aperture and it stops down just before the focal plane shutter goes off. Hence "Automatic". Loving the digital back, cost no money and works a treat. Fits interchangeably with my mini-me Peco Junior view cameras. "Poor Man's Medium Format Digital with Moves".

nitial test of Makiflex Digital Back! Auto Makiflex #1 150mm f5.6 chrome Schneider Symmar Auto Iris Plaubel Makiflex lens mount. Key Day F11 Easily hand holdable, great way to test all my lenses. Much fun ahead. If I want I can switch to film in 30 seconds, although the camera needs totally reset in that case. But so versatile.

  • I wanted a small incogneto digital back, to go on my new Plaubel Peco Jrs. So I took the $60 18mp Sony Nex C3 body, and JB Welded it on to a Peco Jr board with #0 hole. I put a popup hood generic type, with a moncular magnifier that folds out of the way, and viewing is very good with this! Great for lens testing, and eliminates the need for expensive Fujiroid instant material. Exposure readouts in the viewfinder great for determining base exposures through the lens. Shown here with the chrome 100mm Schneider Symmar, ina a later vintage Compur shutter. I am trying to collect the lenses that were originally offered in the Plaubel catalogs of the day. This will be a useful tool for me in the studio, also in the field. I can switch back and forth between digital and B&W film of allsorts in rolls and sheets. This will be fun to field test. Well... it's odd indeed, but could be quite useful.

Nice work again. How did you couple the range finder to the lens gear on this one?

Thanks! On the 2nd pic you can see an attachment on the rear lens group. There is a little plate that contacts the cam follower. Had to extend the latter because it expects a shorter lens.

Do you have a picture of how you attached the cam to the helical gear?

No sorry. There is a ring clamped on the rear lens group, to which the "cam" (just a flat plate) is attached. It doesn't turn with the helical but translates linearly with the lens. I had to modify the rangefinder cam follower for the coupling to work.

Here's me with my TardisCam - a Dora Goodman build in Tardis blue. Basically a soup-up SWC with 50mm Biogon and a Godox Retro flash

Fuji GX680 50mm f5.6 Seiko Shutter by Nokton48, on Flickr

My Plaubel Junior restored with New to me 50mm F5.6 Fuji GX680 lens, purchased broken, at a good discount, from Adorama in NYC. They also included the Gelatin Filter Holder/50mm Hood, it's worth some Dollars so a great deal. The view through the 50mm is AMAZING. Can't wait to shoot some test 6.5x9cm Makina Back Film. EVentually I will buy some type of Digital Medium Format Back. The Peco Junior has a Leica-like smoothness and feel. Plaubel advertised as "The Rolls Royce of Cameras" in the day. Works smoothly and tightly in a Leica-type of way. Also looked through my 4x5" Sinar Normas with this lens. It's amazingly sharp-looking and nice and contrasty view. This will get some use now, rather than becoming an interesting broken ornament. BTW I should mention that I bought the camera for 70 Bucks from Adorama. Another great price. And it included a lens board with a #0 hole

Getting There Set of GX680 Lenses Seiko Shutters by Nokton48, on Flickr

Getting there with my set of Fuji GX680 lenses, with Seiko #2 Shutters added. Mounted on PLaubel Peco Junior boards and Minolta SRT cable releases, Yellow Filters on each, and Hoods too. From the left front, the 50mm F5.6, then the 65mm F5.6, then the 80mm F5.6. On the far right front, the 100mm F4. Back Row, from the left, the 125mm F3.2, then the 150mm F5.6. Next the 180mm F3.2, and on the far right, the 210mm F5.6 Also adding the 250mm F5.6, should be tommorrow, got another Seiko Shutter coming. The 50mm front view reminds me of the HAL9000 fisheye in 2001: A Space Odyssey. It looks about the same LOL

Using Brass Hobby Modeling Screws I bolted a Plaubel 120x120 Adapter Board, to a Sinar Norma Uber Heavy Metal Homemade Machined Norma Board (heavily used) LOL. Always wondered what I would ever do with this thing LOL. So now all my Plaubel Junior mounted boards fit onto the Norma, which I can go up to 8x10, although with these 4x5 will do it nicely. This is the Schneider 135mm F3.8 Schneider Xenar, a not often seen lens, in the F3.8 version. Great to look through on the 4x5 Norma. The tripod is Shulman-inspired Leica Tiltall, modded with aluminum block. This tripod is in Shulman's books on Architecture and Interiors, which I studied intensely back in the Eighties.

50mm Biogon? Did you mean 53mm?

Hee hee, couldn't pass anything lens-related by APUGers I should have said "Biogon type". It's a Mamiya Press 50mm lens, that is... well, Biogon design. F/6.3 So relatively compact. Looks to be similar length as the 38mm Biogon but larger diameter

RICK!! So sorry for the delay, I missed your question. You are totally correct, on both the 6x9 and 6x12 bodies I'm centering the helical (except for one 6x12 actually at the customer's request) which gives you a tad more than a 3mm rise. The very first 6x12 camera I made was for myself because I couldn't afford the original 6x12 Technorama with a 65mm lens and a built in 8mm rise, so I opted to go with the 3mm rise on just about all the subsequent 6x12 projects.

You need more than epoxy, I make four angle aluminum brackets (one of them needs to be sidestepped a bit) and anchor to the top and bottom of the camera and and the face of the panel. Once the panel fits well and is square to the film plane, I metal epoxy over (and under) the brackets and all around to seal it. While 3D printed cameras are fantastic and offer so many affordable options the conversions that I make are truly built to withstand daily professional use if exposed to it. Let me know if you have any more questions, looking forward to seeing your final camera!

Thanks for the reply. That was the other possibility.
