Hi I haven't posted much on (in?) this forum so far, but I have been reading for some time and I like it a lot here. very interesting threads and I've learned a lot so far.
anyway I had an idea for a nice camera I'd like to share here (im not a native English speaker so I hope you understand what I mean).
the basic idea: a modular, mirrorless, sensorshift, sensorfocusing, interchangable lens mount camera.
the sensor: about fx size, however if I could decide I'd go with a 4:5 aspect ratio (but still ok to use with fx lenses), pixel density very high (probably higher than d800 (and more importantly an even higher dynamic range and even better colour), because it will of course take some time to finish the design of such a camera, thus at that time better sensors will be available
. no aa filter (because of the multishot feature)
sensorshift (the full shift range would use the image circle for 6x7 lenses):
1. for regular shifting and rising and so on
2. image stabilization
3. multishot (like the hasselblad mfd backs)
4. and of course for sensor shift stitching
well no mirror but a very nice evf with peaking
in combination with regular "lens focusing" for fine focus and as well as in combination with mf (tripod use you focus by hand with live view and then you use the touchscreen to tell the camera where you want the focus to be perfect) with short focal lenghts you will only have to focus with the lens when you want to use some sort of close range correction of the lens.
and of course for fast automatic focus stacking
interchangable lens mount: ef, F, leica m, mamiya 7? (do those lenses work well with digital sensors?, large format (for those nice digital lenses) and whatever you like
plus a new lens mount optimized for this camera (if the mamiya 7 lenses would work well, and if it would be at all possible and usable I would make the new lens mount to be compatible with the mamiya 7 lenses)
extra feature if possible: some lense mounts (those for large image circle lenses) could be mounted in two orientations, the normal orientation would place the center of the image circle at the center of the sensor (no shift or rise) the other orientation turned by 180° would place the center of the image circle of the lens at the center of the sensor when shifted to the lower right corner (when looking at the camera from the front) for more shift and rise and fall.
the lens mounts would also feature controls for aperture, exposure time
1: sensor modules: square!
1a well the sensor with the shift and focusing capabilities the attachment points for the lens mount and arca swiss style dovetails on top, bottom, left and right (for rock solid tripod mount) electronic contacts for the accessories. on all 6 sides, small battery.
1b high speed (video and still) lower resolution no shift sensor module
2: top, left, right or bottom mount accessories (slides over dove tail, very firmly attached, can be attached on all four sides)
2a viewfinder module: nex-7 style evf (same position, better resolution and faster, peaking, 3d), and basic control dials, wheels and stuff, shutter release, top lcd
2b right hand hand grip with shutter release, some controls, extra battery, you can even combine two of those (right, and bottom or left and right if your not sure whether you are right or left handed
2c battery, different sizes
2d non functional rubber protector lets say you want to use the camera hand held and with only one handgrip and the evf module attached you can put two of those on the to other sides. for better handling
3: backside accessory:
3a small lcd back (high resoltion "retina"), in combination with two handgrips and the evf the camera will look sort of like a pro dslr lots of physical buttons (except for the topsilde (lack of the prism...)
3b large lcd back (very very high resolution 4k or better) a few physical buttons but mainly touchscreen based operation. optional would be a lcd loupe (like the hoodman hoodloupe, very very high quality)
3c no lcd back, just some control dials (if you only want to use the evf), two versions one with battery and a very slim and light one without
3d wireless back (wifi and 3g, and what ever might make sense) the large lcd back can be used as a remote
everything (except some lens mounts) would be weather sealed and the touchscreen would be usable even if wet.
for one shot 3d just combine two sensor modules.
price: in three years: sensormodule, one lens mount, evf, one hand grip, one extra battery: less than $10k
new lenses: if the mamiya 7 lenses work, only some wide angle lenses would be necessary lets say a 35/4, 28/4, 24/5.6, 20/5.6 that cover maybe a little less than 6x7. very high quality and unfortunately probably quite expensive.
what do you think? I'm looking forward to your comments. am I completely crazy (do not hesitate to point that out, if you think that is the case), hopelessly idealistic, just plain stupid, very unrealistic or maybe not so stupid at all?
