Steve, I am about to buy the same camera from a US dealer....do you know if your guys are shipping the ibis5A chip yet...my guy in the US only has the ibis5 chip, it's older and not as good as the 5A...I am doing a conversion of a 16mm film camera with the single chip.

Obin, they sell one chip monochrome and color cameras, I am not sure whether they ship chips separately, you might want to contact them yourself, they are one of the most polite on the market

info@sumix.com

I am getting bad feedback from the IBIS5A chip that the color is not that good...what have you heard Steve? do you have test images from it in color?

No, Obin, they haven't sent me images from the cameras. If we go on with the camera development, there will be no use of getting color information from the CMOS imager. Only monochrome stream will be used.

Steve do you know what size image sensor would be needed for use in a 16mm film camera?

I think you can use any sensor as long as it's resolution is satisfactory to your needs; but then you'll need an Aldus mechanics so popular on this forum. If you want to skip the "mechanical manufacturing" :) step, try to find a sensor which dimensions would be close to the 16 mm :) Simple as that.
I might be wrong but I hope this is as close to the truth as I think it is :)

I hope so too! I am banking on that...I wish we had some sample pictures from that chip before I slap $1,000 down for it!

Steve, looks like chip size is fine...it will be like shooting with a digital slr you have crop factor to deal with..lenses will not be as wide but the imge quality will be very good...IF your lens is to small for the chip/film size then you get dark corners in your image....I NEED IMAGES from the IBIS5A chip that show how well it shoots color!! I have searched the net high and low..still nothing..

Steaming on!

Dear all, judging by responses from sumix, the company went on with the development of the cam.
Possible cost of the camera is estimated to be around US $3000 but you will need your lens and a powerful computer - RAID 5 double XEON 2.4 (or greater) to capture the stream. I just replied a letter from Vladimir, - electronics engineer at the company, he's open to any positive input.
We are considering an electronic RGB filter for the camera.

Please, if you are indifferent, write what you think here, the company is aware of this discussion.

Steve are you still talking about a 3ccd/cmos system?
Steve you really need to use 2/3 inch chips IMHO BECAUSE you get a much more film-like image with the DOF
