YES!Is that a Canon 17mm TSE rehoused in a Copal/helicoid? Are the floating elements used?
Through the modification, adding focusing components, Large format lens shutter, the flange sleeve, realize the shooting.Any idea of the cost for the "Mini TC"? The only link I found has it for 8800 Yuan, which is a bit above $1300 US dollars.
Would be curious about the Canon lenses as well... How does one change the aperture on such lenses?
HiMy bad, have just had a better look at the image of the Canon lens and have seen it has been placed together with a Copal shutter...
Pricing for the Canon 24mm TS-E seems to be about 11,000 yuan which works out to be about $1650 US Dollars and 15,000 Yuan for the 17mm TS-E which is about $2250 US.
Not sure if that is right though
Any downsides to incorporating a shutter into a lens like this?
Obviously the downside to this design is that it can only be used on this camera, unlike the Cambo which leaves the original Canon lens intact...
Still, potentially a lot cheaper..
I would have liked to see either Contax 645 or Hasselblad H lenses with this technique, that would offer something that is not currently available..
HiDeng---you're a tease. Tell us more! Do you have this camera? Quality? Tolerances? Digital back compatibility? Details etc...
Copyright/patent infringement could be an issue, but this 17TSE modification is surely interesting - it is certainly a better solution than the Alpa 12 FPS. I never liked the idea of Alpa 12 FPS because it's heavy, bulky and its shifting capability is too limited (either no shift for Rodenstock wide angles or no back shift with the TSE lenses).
I am no expert in this area. I believe Nikon used to sue Sigma for some kind of patent infringement. Maybe at some point they can make gear like Tamron/Sigma without any patent infringement but as this area is too specialized for the minority no one really bothers with the grey areas.what patent has been infringed?
making a view camera with geared movements is not an exclusive right belonging to any one manufacturer?
I agree; but just what form that 'solution' takes can be protected by a patent.what patent has been infringed?
