Some full frame digital cameras were and are relatively low resolution: The Canon 5D was 12.8 MP and was released after the 17MP 1Ds Mk II. The Nikon D3 and D3s were 12.1 MP. The D3s was introduced a year later than the 24.5MP D3X with twice the resolution. As of late 2015 the highest resolution full frame models are the 50MP Canon 5Ds (and 5DS R variant) ...


The only decrease in quality will be the likely performance difference between the Full Frame and APS-C sensor. In general FF lenses used on APS-C cameras perform slightly better than when used on FF cameras because the edges of the light circle cast by the lens, where most of the weaknesses of a lens are most obvious, are cropped off by the smaller sensor. ...


You won't be able to get the best results from just theoretically analyzing one or more effects that cause blurring. The best way to proceed is by measuring the blurring and then do deconvolution based on the measured point spread function. You can print a some black and white pattern costing of lines in different directions, or circles on a piece of paper. ...


Yes, the anti-aliasing filter on most digital cameras is an optical filter that blurs the light just in front of the image sensor. But for your purposes that is the least of your worries. The way a Bayer filter mask works on the overwhelming majority of digital cameras means that the actual resolution limit of cameras so equipped is about 1/2 the number of ...


Although Comparometer or other samples don't show any radical improvement in the image quality (even with high ISO values) and eyes of many users on discussion forums support that, there are other benefits. The stacked CMOS Sensor in DSC-RX10 II allows shutter speed up to 1/32000s (rolling shutter), continuous drive at 14fps and ...


From what I know ISO settings do not change in any way the sensor behaviour. The "magic" is done after the signal is read from sensor. There is amplifier, which amplify the signal with value of ISO change. And there is no way to change the power of photon as this is constant value


Many of the things you want to eliminate are actually important for answering this question in the real world. In practice, image quality almost never comes down to sensor characteristics. I'm a little reminded of this Monty Python sketch..... when you eliminate all of the image quality factors other than the sensor, sure, the sensor is the only spec left. ...


I ordered a sensor cleaner from eyelead in Germany. It's a gel pad on a stick, that the dust sticks to. The pad is then cleaned using adhesive paper which is more sticky than the pad. It's a bit tricky to reach into the corners because the pad has rounded corners, but other than that it works great to get dust away from the sensor. As there is no cleaning ...


Moire occurs because the scene is sampled at a discrete resolution which is the nature of digital imaging. There is nothing to do about that but reduce the frequency of the signal reaching the sensor. In fact, moire occurs in monochrome sensors too which have no sub-pixels. The matrix of pixels form a fixed grid to sample an image formed by incoming light ...


From the abstract of this article Color filter array for CCD and CMOS image sensors using a chemically amplified thermally cured pre-dyed positive-tone photoresist for 365-nm lithography Diazonaphthoquinone-novolak photoresist is used to produce these filters by successively depositing and patterning each color layer. My understanding of this quote ...
