Ah that explains it , so then when the rear element is very close to the sensor there should be a hot spot , do not have that with the 55 f1.2 which has a rather large rear element very close to the sensor , have n`t noticed anything sofar , but then the slrN has no AA filter , which makes it susceptible to moir¨ tho`.
It's not so much the closeness, as how flat the rear element is, the Nikkor 50-1.4 has a very flat rear element, from my limited experiments that lens has about the flattest rear element I have seen and I believe that is the problem. This is another aspect of 'optimising for digital' Film doesn't reflect in the same way as the LPF.
