    MTF Charts vs. Sharpness in the field

    I have a 135mm f1.8 lens and a 400 f2.8 Lens. While the 400 f2.8 has "perfect" mtf charts and the 135mm f1.8 does not, the 135mm f1.8 shows way more sharpness in a field test. Im talking about the sony lenses here. I tested this with the 61mp a7r iv. I shot a testsubject and framed it the...

    Question about depth of Field with a 400 f2.8

    Can multiple (or dual) native iso technology be applied to photography?

    I have seen the technology in film cameras and used for video recording, but is it also possible to use this for photoraphy? Could this be a useful improvement for cameras like the 7d iii and idx iii?

    No 7d iii in 2019!

    Recently a list of camera certifications for 2019 got posted. There are only 3 cameras that "could" be the 7d iii: the K437 (32 mp dslr) the K435 (24 mp dslr) the K436 (24 mp dslr) It cant be the K437 because there is no way that they are gonna use a 32mp sensor for a high fps sports cam. And...

    Is it realistic for the canon 7d iii to match the image quality of nikon d500?

    When you compare Images of the 7d ii with images form the nikon d500 you can see two things in favor of the nikon d500: More sharpness Less noise at high iso I think that canon can match the sharpness of the images of the nikon d500 by removing the AA filter. But iso performance wise it is atm...
