There is little difference between the high end modern (last 2-3 years) lenses made for Sony, and that is why responses cover a lot of lenses - what most have in common is 'recent year of manufacture'. Sony's GM 35/1.4 has near-incredible corners - at f1.4. The new Leica APOs are almost exactly the same everywhere in the frame, the better CV APOs too. At infinity, it has super on axis performance but fades in the corners, at best aperture. For example, just above we see reference to the Otus 85/1.4. What aperture do you want to use? What other aberrations can you tolerate, how much computer assistance are you happy with? APO lenses trade off leaving some 'easy to fix' lateral CA for superb longitudinal CA performance (not just my opinion, Peter Karbe says this too).įocal distance too, infinity or near distance. Then, sharp where - centre, midframe or corners, or a balance of these locations. It's a surprisingly complex topic, starting out with acutance, micro and macro contrast and resolution - there are trade-offs at the limit. The 135mm gm, 24mm gm, Sigma 35 1,2 and Sigma 85mm dg dn are less sharp. On this germans site '''' i was looking for the sharpest lenses from sony and sigma, the 50gm is with the 20mm the sharpest.ģ. I know the site, because of them i buyd the 20mm They have published MTF's for some Sony primes here. Lenrentals is probably the only place that could give you a reasonably scientific answer. Lenses that long are extremely difficult to test in a manner that allows for meaningful comparison to other focal lengths (if that is what you want to do). In native E-mount the FE 600mm f/4 is likely king/queen/emperor. So by default most long lenses (300mm+) are going to have higher MTF50 results over more of the image area than a wider lens. Generally speaking, it is easier to design a long focal length to be "sharper" (a term that deserves it's own debate) over the entire image area than a wide lens.
