Title: making compact technical camera for A7/A7r
Post by: chiek on January 29, 2014, 03:08:07 am
It will make H/V position revolving and can X-axis shifting +/- 20mm.
I thought gear driven shift mechanism first time but It will cost more, so Thinking insert stopper to -20mm / 0 / +20mm.

It can delivers on A7R,
1 shot (36mm x 24mm / 24mm x 36mm, 36.4Mpx)
3 shot
Horizontal 76mm x 24mm , (approx 75Mpx)
Vertical 64mm x 36mm, (Over 80Mpx)

A huge image size, It's over than I expect.
It can using various lenses, Hasselblad V, telephoto MF nikkor lens, any other Perspective Control lens as EF24TS-II, EF-17TS, olympus shift etc.
Personally, I hope to use Xpan lenses but It's hard to find in Seoul.

I have not A7/A7R body yet. I'm watching Body price. It's price has down and down… ;)
disassemble EF lens to sony nex adapter with electric contacts, fit to GX680 lens boards and my custom A7 body mounts…. then It can live view focusing in technical movements and work electric aperture.
So comfortable for still-life photographers !

I think It can sells worldwide.

I'm importing EF-nex adapter and Other materials are ready to making.
and thinking to buy 7" high resolution HDMI monitor for larger live view and composition.

Note.
It needs GX-680 I/II/III body but NO GX680-IIIs. <--- It can't technical movements.

Any comments are welcome.

My goal is under US$1.5K including
modified GX680 body
standard bellows
1 x copal 0 lens board
X axis gear driven a7 camera mount.

I need a money for making, modifying, plastic mock-ups… (almost for machinist)
CROWD funding ?  :)

It will make for Sony A7/r body and canon EF lens mounts.
H/V position rotating.
Gear driven X axis shift range is approx 100mm (+/- 50mm)

Being able to mount perspective control lenses is listed as a feature. Seeing as Canon TS lenses can currently be mounted onto a Sony A7(r) using a basic adapter, how does this proposed technical camera improve upon this existing option?

Would it be possible to build something like a RhinoCam that tilts?  If the ground glass feature of a RhinoCam was removed, and a tilt feature was added, that would interest me. The RhinoCam sells for $300. If adding tilt is possible, maybe that would bring the cost up to $500?

No, Edmund.
I want 35mm full frame + some more movements (1.5 ~2x image circle)

Many good lenses have larger image circle than 36x24mm, olympus Om, leica R, mf nikkor.
And these lens are own special character as bokeh, color, etc...

I just want to use it.

the lens mount adapter is simply not good enough.
you need to mount the sony directly on the rear bearer (instead of the former film frame) and to manufacture a custom bellow with Sony lens mount, in order to be able to use shorter lenses and bigger movements.

I've been using my A7r on my Cambo Ultima for almost 2 months now and its been great.   I am running the camera off the AC adapter, tethered to Sony RCC which then goes directly into C1 7.2.   I also have a 22 monitor on a rotatable VESA mount next to the camera stand for a larger live view.   

Sorry for the crappy iPhone pics

How did you attach it? Where did you get the adapter, is it on a lens plate? Can you use wide angle lenses?
Thanks!

Its attached directly to the Ultima 35 bag bellows.   I started by purchasing a Macro extension tube on EBAY for the E Mount - took it apart to get the actual metal mount and retaining ring off of it.   I unscrewed the nikon mount from bags, centered the new E mount on the bag hole, punched new holes for the new screw pattern and screwed it into the retaining ring which is on the inside.   Removed the rear mount and inserted one of my 35mm horizontal canon mounts which is screwed to a Hejner L bracket Base 4 and a Side 3 with the camera mounted on a Nikon TA-N100 spacer to raise the center of the sensor. 

Simple to rotate from H to V by just undoing the bellows at the lens standard and rotating the L bracket. 

Works great with my 28 digitar and 35 & 45 Biogons - no need for a recessed board and I can get the rear element all the way to the body.

Sony a7 has very short flange back so It can accepts Most lens. so I designed for shortest flange DSLR, Canon EOS.

Seriously, it's the best choice by far. Not only shortest flange but also the biggest diameter mount in 35mm.

Thanks, Edurado.
Many people interested and asked functions. so I will generate for upgrade idea.

I think If this camera enable EOS AF & aperture control, like metabones3, It will be better.

I tried it and I think It can make it. but Very difficult work so Price will be very higher…



My idea added rear shift scale.

Arca-Swiss has just released the bellows for their DSLR2.  And we have redesigned the mounting to make it fast and easy to use.
The mount will allow the use of wide angle lenses down to at least 35mm and we are testing to see how short we can go with movement.
The rear of the lenses, especially on the Rodenstock's is so long that it contacts the body of Nikon's and Canon's below 70mm.
The Sony A7 series, being mirror-less, allow much shorter lenses to be used.
I will have pictures soon this week.

Additionally to make it easy to use, the bellows mount works as follows. Mount is pulled off from bellows.  That's right, pulled off.  It is a magnetic rear lens mount with a finger cutout to make it easy to rotate on the body.  Mount the bellows to the the front frame of your DSLR2 and reconnect the two rings via the installed magnets. As the two rings nest inside a perfect seal and light trap is created.  Turn on your body and you are ready to make images.  If you switch to vertical or vice-versa, you merely need to reorient the body and the bellows mount will rotate in place.  You now have an extremely precise camera capable of using wide angle lenses on your DSLR with ease.

All three mounts will be supplied in this form in the future.
Enjoy!

Post by: Rod.Klukas on April 29, 2014, 04:08:58 pm
Still not sure.  I am trying to get the lens mount to sensor distance on the Sony.(depth of body...)
The 32mm has a 22.3mm distance at infinity behind the rear edge of the lens to the sensor for sharp focus.
The 23mm and 28mm Rodenstocks are both 16mm ...

Post by: lelouarn on April 29, 2014, 05:11:11 pm
So in this case, do you remove the rotaslide spacer from the lens to get more room between the camera body and lens's rear element ?

Also, any idea when this thing will be "available" ? Sometimes A/S products take their sweet time to be delivered. Also, I assume, we will be able to see it at the photokina ?

Since the 32mm is my widest lens, it's important for me that it fits that lens (on a Factum body). Using the A7R + my set of HR lenses would be really nice !

The setup is designed to use digital LF lens so they can be moved.  Rise/Fall or Shifted or tilted.
A zoom for Canon or Nikon, or any DSLR is designed to cover 24x36mm Sensor, except for T/S lenses.
So there is no reason to mount the Zooms etc, as they do not allow for movement on this setup.

Many reputable lenses are larger than 36x24mm
Contax C/Y 50 and 85mm are almost 2x larger than 36x24mm and edge image quality is very good. olympus OM does, too.
Generally, zoom lens set from wide to tele, Image circle are larger. We need just select Good edge lens.

Like me, product / sometimes interior photographer needs some movements, not a 3x, 5x, 10x movements.

If we need more movements, Just use Rod. digaron or Sch. digitar, so do I.

Of course, almost all medium format lenses are fitted.
 
I'm thinking how to set aperture contax 645 lenses.
it can do like canon eos lens.

from this camera site FAQ,
http://chiek.co.kr/list/view.php?id=6807&page=1&sn1=&divpage=1&sn=off&ss=on&sc=on&select_arrange=headnum&desc=asc&no=4 (http://chiek.co.kr/list/view.php?id=6807&page=1&sn1=&divpage=1&sn=off&ss=on&sc=on&select_arrange=headnum&desc=asc&no=4)

5. Can I set EOS EF lens aperture ?
Yes, Very Easy.
First, attaching your lens to EOS body (film or digital).
Second, set the aperture you want
Third, push depth of field preview button and holding and unmount it.
You will see your lens setting aperture.
and mount this cam.
--------

but I want to set aperture whenever free setting, not above.
so I will get contax645 lens and disassemble in near future.
I guess it is very easy and recoverable.

If possible, it's killer lens on this camera. contax645 lens price is very low on image quality.

Full Stitching Test 214 MEGAPIXELS

Mamiya RZ 50mm set to F11, 4sec ISO400 (5 x 2 shot stitching)
cropped image size is 17895 x 11988 pixels. (88mm x 58mm)

front rise with stitching 5cut + front fall with stitching 5cut

Edge Sharpness is NOT GOOD.

Effective sharp image size is approx. 70mm x 50mm.

Because of Front Lens standard movements, It is difficult to perfect stitching.
It must use sturdy tripod, all movements lever locked during all shot, Cable release OR self-timer needed…

Many people wants +Y axis geared shift.
but I think it's size is more larger.
like this, below pictures.

I don't like larger camera. Just Only wants compact technical camera.

Is it alright for many photographers?
How about your think?

Hi Chiek,

I'm a photographer from Toronto, and am very interested in your setup.  Will be one of your first customers when you have production cameras available.

Do I presume than using my Cambo mounted Rodenstock lenses can't work here? I'm not just thinking of mounting, but of flange depth and distance to sensor etc.

This concepts can use almost lenses because of very short flange back.
if you want to use standard copal lenses, you can buy extra copal lens board.

short flange lenses, like 35mm lens, are mounted on rear face of front standard.
standard flange lens, like medium format or largeformat lens, are mounted on front face of front standard.

please check this camera concepts,

On the "Chiek system" (great work!), does the lens move for incremental focus or is it the sensor? I would surely need the sensor to move, not the lens.

Very easy switchable.

You can select 2 types,
1. stick front(lens) plane and Rear(camera) move.
or

2. stick Rear(camera) plane and Front(lens) move. Same as Original GX680.

Very interesting concept. I like it a lot.

Can I use my Schneider lenses from my Cambo WRS tech camera on this? They al have the proprietary Cambo mounts.

I dont know WRS lens board size. but I guess it's larger than gx680 board.
but gx680 system can fit standard copal 0 lensboard so you can put your lens, unscrew front/rear elements  from wrs board.

I take it if someone owns a Sinar system already and is not looking for portable or more compact alternative, there isn't much this is offering?
Or am I missing some point Chiek? I ask this as I am unfamiliar with the core of the Fuji system.
Thank you

Easy Changing to MFDB instead of a7 camera.
