    EOS mounts is just bridge for MOST lens and PLUS enable 17, 24 TS.

    My idea added to rear shift scale.

    Thank you for your answer. I think that I'm beginning to get it : both the lens (front standard) and the back standard holding the camera are moving in a perfectly synchronized manner ? The goal is mainly to stitching several frames more easily (no parallaxe problem, since everything always move in the same plan and remember parallel).

    Did I get it correctly ? Then if the movements of the two standards (front and back) are perfectly synchronized it isn't exactly what we name a technical camera.. But still an interesting idea.

    Great set up! How much would it cost for a 645 Pentax lens plate and a APO Rodenstock enlarging lens mounting plate? What is the time frame for delivery and is there a warranty? When is the next model coming with more shift capabilities?

    Frt/Rr standard is perfect paralell that is my goal, too. I tested 2times during making, Both test checks parallax check especially final test.

    DennisHHH, I'm just a photographer. Not a machinist or maker.
    I will ask my machinist how much but if special order like you, it needs pentax645 parts like disassemble extension ring, it will be cost higher.

    Standard copal lens board is very easy to make but special orders, like pentax645, contax645 (I think it is one of the best for my concepts, however aperture set not convenient like eos aperture), hasselblad cf or H, are needs special parts so price is more up and up.

    Delivery times and others, please visit this cam site FAQ.
    http://chiek.co.kr/list/view.php?id=...2e02d083e57694

    This is just a concepts for technical movement photographer.
    Concepts design will be more generation. I added rear shift scale today.

    Any comments are welcome.

    Thanks for interest.

    Re: making compact technical camera for A7/A7r

    Hi Chiek,

    I am wondering, why would I want to attach a Tilt/Shift glass to your Tilt/Shift construction? What is the advantage?

    I know, probably a most stupid question, but if you never handled a technical camera, funny questions can pop up at times.

    Thanks!

    Re: making compact technical camera for A7/A7r

    Arca-Swiss has just released the Sony 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. It appears the 23mm and 28mm Rodenstocks are out. 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 and even on the Sony A7 may not work.
    The Sony A7 series, being mirror-less, allows much shorter lenses to be used, so more soon on this.
    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 to connect to 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 want to 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. And the Leica M mount is coming for the M240 crowd.
    Enjoy,
    Rod

    Re: making compact technical camera for A7/A7r

    For anyone wanting to squeeze out the last mm of shift/Imagecircle from the Canon TS-E 17mm and TS-E 24mm V2 we offer special mods to "reach parts other lenses don´t reach"........
    Especially for Chieks Camera, HCam-B1 and Alpa FPS and all others which can use TS-E with movements or larger than 24x36 sensors this is the way to get all around about 3mm + for the 17mm and up to 5mm for the 24mm !

    PM me for more infos and Pricings/procedures.

    Re: making compact technical camera for A7/A7r

    Hi,

    I have been following this concept very keenly, as it seems perfect for what I am after and much cheaper than any other options available...

    I just stumbled across this post where a photographer named Fred Greissing has done a similar thing but he has placed a GX680 front standard onto the rear, essentially giving him both front and rear full movements..

    https://secure.modelmayhem.com/po.ph...=896067&page=3

    This also gives him the ability to stitch on the back, both vertically and horizontally, giving a rectangular image greater than the Rhinocam.. He says the "Virtual sensor area will be 78x58mm"


    Just wondering if this is at all possible with your modification? Or is it really only possible with the original GX680 lenses to achieve this?

    He also talks about having a Ground Glass for viewing the stitched image but i cannot seem to find that link anymore..

    If it was the case that this back was not possible with shorter focal length lenses (like Canon 17mm and 24mm TS-E) would it be possible to have interchangeable backs? Yours when wanting to use shorter focal lengths and then one made up of a recycled front standard that has full movements for stitching?

    Ok, thanks so much again, great work!

    Re: making compact technical camera for A7/A7r

    Here is the link to the other forum where he mentioned having a separate focusing screen for what the final stitched image would look like..

    Fuji GX 680 View custom made 36 to 200 MP Tilt shift camera. - FM Forums

    Obviously, this setup becomes a whole lot more compact with the Sony A7R!

    Any thoughts on what he means by this comment "What is really nice is that the D800 sensor has an anti alias filter so even the 200MP captures will have minimal or no color aliasing artifacts, unlike my MFD backs had, not to mention far more resolution."

    Is this an issue with the Sony A7R due to the fact that it is lacking an antialiasing filter?

    Thanks again...

    Hi,
    Actually, I thought same idea, 3~4years ago. on LULA forum.
    http://www.luminous-landscape.com/fo...hp?topic=42041
    If rear standards is GX680, It may be stitching error during stitching movements. gear driven is more stable for image than standard movements.

    Vertical/Horizontal both… It will be complicated. so It may can't short flange back lens like 17,24TS.
    I want to keep short flange back to use the Best 35mm lens.
    and my design is being improved.
    now It is changeable, bellows reversing, so It can use ALL lens, short flange lens and MF, LF lens.

    Mirrorless is only answer of this case.
    I heard fuji developing FF mirror less but their system is more longer flange back than Sony Emounts 18mm. SONY win.

    typical adapter like below,


    because of deep lens mounts (includes mirror), It has limited movements.

    Re: making compact technical camera for A7/A7r

    Chiek,

    I just stumbled upon this thread and am amazed; I was just wondering why there was no bellows option made for many of our cameras, and was looking at the Fuji 680 as a potential solution. Can this be adapted for my Phase/Mamiya 645 camera? I would be interested in one, and if you cannot make the Mamiya adapter, perhaps the machinists at S.K. Grimes could make one.
    On the front standard I would want to attach the current Phase/Mamiya lenses.
    Thanks,
    John

    I will make custom technical camera using GX680 frt in near future.
    It has including larger shutter (copal 3 or ilex 4) and Medium format digital back mounts. I think It is almost lens Medium format, large format and 35mm lens (short flange back).

    It will be modular system, It means this concepts (a7/GX680 combo) will changeable to MFDB.

    It's my next project.

    Re: making compact technical camera for A7/A7r

    Hi Chiek,

    First I'd like to say you've done a wonderful job here!! Very nice project.

    I've never used a GX680 camera so i don't know that much on this system.

    I'd like to know if:
    1) we can rise front then stitch, considering the lens attached gets enough IC, MF or LF lenses for example when (if) you've got the plate. And how much rise "mm" is possible.
    2) Better: Rise back then stitch, a bit like an Alpa Max with level stitch adapter:
    ALPA Stitch Adapter Max - YouTube
    3) Rise the lens (so only TS) then stitch.

    As an Architectural photographer features 1) and 2) could make A7/R + "Chiek" system a real game changer

    Thanks
    Jérôme

    This camera enables not only rear X-axis shift, but also front rise/fall +/-13mm.
    So it can stitched X axis + Y axis by photoshop photomerge function.

    It can build up to over 20000px x 10000px, like rhinocam. But I don't like that because of lens standard shift. It means image may be produced and edited by software (photomerge).
    Only rear shift can make pure lens image, I like that.

    I agree (2) like alpa max, very difficult making because of short flange back.

    I'm thinking about this system + Y axis shift... Actually, it is not impossible but total price is more up and up because of complex design.


    I will test medium format lens with this cam, I have mamiya rz 50, 110, 180 and rod digital 60HR and old rodie 80mm digital lens.
    But now, I have not adapter or lens board for my lenses. :-)

    Re: making compact technical camera for A7/A7r

    Whoah! That is awesome! Very impressive!

    You mention that it is possible to have a back that stitches both vertically and horizontally and that it would be more expensive to make..

    Any idea how much more expensive? Would it be geared?

    I would be interested in this as I am mainly interested in a more rectangular end format, closer to 8x10 film..

    Ok, thanks again, great work!

    Full Stitching Test 214 MEGAPIXELS

    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, Image size is more larger but It is difficult to perfect stitching.
    It must use sturdy tripod, all movements lever locked during all shot, Cable release of self-timer needed…

    Hi Chiek,

    Wow it is great!!

    Some questions:
    . You said it was difficult to merge...like to be forced to make "strong" layers adjustments in Photoshop? Because of lens distortion? I have some kind of troubles to photomerge my 24 TS-E rise/fall stitches sometimes, specially with near objects, even using PT-lens first, that's why I'm asking.

    . What would you say about the focal length (35mm speaking) resulting from the sharp 70x50 stitch... 20mm?24mm? (it may exist a kind of calculation for this but it's not my cup of tea! )

    . Did you rise/fall max 13mm for the test? So bad GX680 does not front rise more!

    . RZ lenses are very nice, sharp and cheap, it's a good option for this system.Did you use a special plate?

    I'd enjoy trying this with Contax distagon 35mm 3,5 - 40mm CFE or Hartblei 40 T/S!!
    As Wallpaperviking say, it would be great to have an estimate price, as soon as you can, for a geared back X/Y stitch!

    Thanks again
    Jérôme

    70mm x 50mm is very similar to 67mm x 56mm, original 6x7 film size.
    so It is 20mm focal length to equivalent 35mm film.

    GX680 maximum frt rise/fall is 13mm , so I shot frt rise 13mm and fall 13mm. Vertical image size is 13mm + 36mm + 13mm = 60mm.
    Final cropped to 58mm.

    RZ lens board… I made by plastic for temporary testing.using RZ lens rear cap.
    If we make Rz lens board, It needs 1 RZ extension ring, disassemble and put GX680 board.

    I agree your opinion Contax 645 distagon 35mm or Hartblei TS40mm , It's best wide lens for medium format.

    Rear X/Y shift… It's my goal… Design is completed, Just Only in my thinking. but not yet.

    Thanks for interest.

    Re: making compact technical camera for A7/A7r

    Hi Chiek,

    Awesome work once again!

    I just had a quick question, was just wondering what the longest/heaviest lens is that you could place on your camera?

    Would a Canon 70-200mm be possible? It weighs 1570grams.

    I see the Fuji GX680 has some seriously heavy lenses including the 500mm f8 and the 100-200mm 5.6 zoom (which may need extra support).

    So I assume they have made the front standard strong enough to support quite a bit of weight..

    Am wondering if this would have any effect on the "shutter vibration issue" that many people have seemingly reported with the Sony A7R when using longer lenses?

    Ok, thanks so much, eagerly look forward to further progress with having a stitching X/Y back

    Thanks again!

    Yes, GX680 frt standard can support heavy lens, I guess It supports 70-200L. (I have not. )

    I see a7R's vibration issue. but my experience, I have not issue on Handheld / tripod shot.

    If I make rear Y axis Gear driven, I think it's size is more larger.
    Is it alright for many photographers?

    Re: making compact technical camera for A7/A7r

    I would be very interested in having a camera that enabled X/Y geared axis shifting! I was looking to purchase and then modify a Rhinocam for use on the Sony A7R but your concept seems to be a much more well rounded, complete package with a lot more options

    Coming from a large format background, one thing I do like about the Rhinocam, is the ability to "previsualise" the final stitched image by viewing the image on the supplied groudglass.. I do not know if that is at all possible with your concept but I think for landscape/architecture it is very important..

    Great work, look forward to the progress!

    ..hmm..i personally wouldnt have a problem with this design..

    ..i hope that my question is not too stupid..sorry in case i didnt get everything right: the rails that fix the "front standard" and the "rear standard", do they have to be that long ?

    ..if i imagine storing the camera in my bag i had more problems storing it because of the rails than because of the geared rear standard..

    ..just my 2c..

    ..even with gaining bulk i would prefer the geared rear standard..

    ..erik..

    Just Done my commercial shot with this camera.
    Many benefits for shooting. Very easy doing movements, live view with ipad and similar MFDB quality.




    I'm very pleased using my concepts cam for my job.

    Fantastic shot!
    I just emailed you with questions on the system I need it for fine art reproduction , so ideally it has to have shift in both axis, can you do this?
    Keep up the good work!

    1st Early birds 10 orders preparing to ship. Now, Final Testing.
    Thanks for purchase. but It is Very hard work. I hope to discontinue this… ;-)

    It is new design, I called version 1.5. changeable bellows systems so can accepts long flange back lens like GX680 telephoto or large format lens.
    Y axis not yet (version 2.0).
    actually, Design is completed but not make yet. I want to Rest.

    Re: making compact technical camera for A7/A7r

    Massive congratulations to you sir! That is all kinds of awesomeness!

    Please put me down as your first pre-order with gear driven Y-Axis camera!

    That is, after you have had a well deserved rest

    Just had a few more questions..

    * Will the new version have electronic contacts to enable communication with Canon lenses? It's no problem if not, changing the aperture is possible with the Metabones adapter I have but of course it would be more convenient

    * With the new gear driven Y-axis version, will it be possible to effectively stitch to the whole image circle of the original Fuji GX680 lenses with no parallax? Rear Y-Axis and Rear X-Axis?

    * You have previously mentioned using a Hasselblad X-Pan lens on it, given it is a rangefinder lens with a flange distance of 34.27 and the Sony E-mount is 18mm, is that enough distance to use and have movements with?

    Ok, thanks so much once again and congratulations on your great work!

    If anyone on this forum has ordered one, it would be great to hear your thoughts on it as well as seeing some sample photos..

    Version 2.0 summary




    But Not yet, It's future projects.
    I'm very busy for my job, commercial shot.

    How much do the price is fair , good price ? (X axis +/-50mm, Y axis +/-15mm).
    Actually, Some trouble in my job, commercial shot because of these making camera.

    Canon Electric aperture is tested but Not NOW. maybe version 3.0 ?

    Chiek,

    having "looked over your shoulder" from the very beginning to the final product shippment, I would like to congratulate you for a truly outstanding achievement. I can't wait to read the first user reviews and see examples of their work.

    You must be very proud in deed, besides probably being very tired too, to see the first final shippment leaving your place. This thread started in January this year and is one of the most interesting I had ever come across. You had a dream and you manifested this in a very short amount of time. I sincerely hope that sales exceeds your expectations multifold. You deserve it!

    Amazing accomplishment Sir!

    Best wishes
    Georg

    I'm very interest in What photographers wants.
    When I take a photographs for my job, I need some features like simply shift/tilt. and I hope to use GOOD resolution compact camera through my several brand lens.

    That's all.

    You understate.

    I understand that your development came out of your own requirements. However, don't sell yourself short, it is quite an achievement to pull that stunt in a few month and have a ready to be shipped product.

    Anyhow. Thanks for posting in the techcam examples thread!

    Re: making compact technical camera for A7/A7r

    Chiek, congratulations again. You are awesome man!
    I wanted to tell you that an EOS electronic mount would be perfection.
    I just returned a Rhinocam because I didn't like the results from my Hasselblad V CF lens. The 140 mp stitch produces a sharper more detailed image than one single (A6000) shot with the 20mm prime but the difference is not espectacular. Many problems can be seen as a general very subtle fog. I'm sure the lens is fine as it works great with film (not a surprise here, of course).
    I think the V glass is obsolete now as most MF legacy lenses.
    I'm pretty sure that I would get a comparable to the 140mp V glass Rhinocam (if not better) image using an A7r with TS glass.
    A lot less hassle and a lot quicker.
    My V legacy gear definitely goes now to the family memorabilia trunk in the attic.
    Best
    Eduardo

    Canon Electric aperture is tested but Not NOW. maybe version 3.0 ?
