You do understand that the sensor significantly needs to "outresolve" the lens to get the most of the lens?
You will gain total resolution even with the worst available lenses by increasing the pixel density in the current pixel range FF sensors are at.
I am very keenly aware of this issue seeing as I've preformed real world testing to see it's effect and I've actually run the theoretical calculations on it aswell.
Due to the extremely low resolution of Nikon's lenses they stand to gain only 8% more resolution by going from 24 MP to 36 MP for their higher end lenses. Canon's lenses would stand to gain 25% more resolution by going from 21 to 36 MP on the higher end lenses. Theoretically speaking.
Can you explain to those of us less tech oriented - what you mean by saying a lens cannot "resolve 36 megapixels" ?? thanks
There are many ways to atempt to turn a resolution curve from a lens into a flat linear resolution. Two ways are to take the integral of the resolution curve and then average that over the area, or to take the resolution at the half way point of the area of the image and extrapolate it over the whole image. I use the latter because it's easier and the results are fairly representative result.
Would you care to clarify your argument? For example, are you referring to centre or edge of frame resolution? Where are you getting your resolution figures from? I hope that as an engineer you're calculating them from MTF charts and not using the LP/PH from Photozone, as this will change for each lens based upon the resolution of the sensor that the lens is tested with.
I am using the photozone data, BUT I am using the crop frame boarder (not extreme corner) resolution data and extrapolating it to the full frame data. This essentially mimics a 40 megapixel sensor at the half way point of the frame which is an extremely accurate way of measuring considering we're dealing with a 36 MP sensor. Most of Nikon's lenses are barley resolving two thirds the resolution at this point so it's safe to say that they wouldn't take advantage of 36 megapixels over the majority of the frame.
