Otus85mm_SonyGM85mm

We will all agree the [shoplink 44778 ebay]Zeiss Otus 85mm f/1.4[/shoplink] is the world’s best 85mm FF lens. Right? So let’s compare the MTF graphs between the new Sony 85mm GM lens and the Otus (Sony is on the left and Zeiss son the right):

MTF

Notes:
– Zeiss has two MTF graphs (short focus and infinity). Sony doesn’t specify that but I assumed Sony measured those at short focus (based on the line typology)
– Zeiss measure the MTF graphs on real production lenses while usually other manufacturers do “calculate those” which for example doesn’t take into account diffraction.

Conclusion:
Of course this isn’t a 100% fair comparison as the exact test conditions are unclear. But it looks the Otus is still clearly the best lens. Of course it also costs twice as much as the Sony GM (and it has no autofocus). And the new Sony is “trimmed” to get a superb bokeh. And that’s where the lens could beat the new Otus…maybe.
