CCD versus ?

[dee]

Thanks again.
Monochrome on the A290/390 has some depth too - I must concentrate upon this pair one for B/W and the other for colour .
I guess that the Minolta 35-80 4 and 35-80 3.5-5.6 in silver are adding to the results.

I'm surprised no one has mentioned the CMOS sensor jello effect yet 🙂

Depending on the application (I'm thinking flourescence microscopes for research work here), a CCD sensor is absolutely the preferred choice of imaging sensor, and if you have an EM-CCD sensor in your camera, limitations due to high ISO noise no longer exist either 😉

Clearly the aesthetics of the final result are most important. People like what they like. Different people like different renderings and different people like different cameras.

It is ironic that both CCD sensor assemblies and CMOS sensor assemblies use pinned photodiodes solid-state electronics in order to convert light energy to electrical charge via the photoelectric effect.

All camera sensors are CCD devices.

What people refer to as CCD sensors are simply an out-dated manufacturing process. They are out dated because using separate electronics components in a camera's data stream results in more noise than having all the data stream electronics on a single, integrated circuit. The higher manufacturing costs of a CCD assembly is aesthetically irrelevant, but it is another reason why CCD sensor assemblies are out dated.

The M240 uses a CMOS sensor assembly and its color rendering is excellent. Conversion from light energy to electrical charge is not the step that is determines color rendering aesthetics. It is not necessarily the step that determines signal-to-noise ratio or dynamic range.

If only Dee was contemplating buying an EM.

It turns out the CCD technology you mention is limited to 1024 X 1024 pixels and must be cooled to -100 C.

Never know. His day job might be researcher of biological processes in light starved environments 🙂

Seriously though, I certainly don't think anyone here is contemplating buying an EM, and the technology is obviously never going to be used for consumer camera sensors. But its interesting technology to contemplate nonetheless. Lighten up a little.

There is nothing simple about it. Trying to make it simple you will inevitably generalize inaccurately.

Pretty mich every different people talk about when they say they prefer a CCD sensor has to do with the CFA and the color balance chosen by the manufacturer. This can of course, be profiled on any modern CMOS sensor. There is no difference in clarity, etc, etc. just a myth.

 

[dee]

... so it's a bit hit and myth ?

Amen!!!

I very much prefer CCD, and I have older digital cameras that 'draw' color and pixelation more to my taste and I prefer them over newer cameras.

However, CCDs are subject to cosmic ray damge and the they way they record means that one damaged pixel will lead to the rest in it's line not being read. Nikon had a big problem with this, Leica had it to some degree. The sensor has to be remapped.

Here is a crop from my Monochrom

I've had this same issue with my M-E. My camera is in for its second sensor replacement and this time I've been offered the upgrade option. So its interesting to see the CCD vs CMOS thread pop up again.

Fascinating !!
Way over my head !
