On kyllä massiivinen vinjentti. Mielenkiintoista, että pesee jopa Otuksen reunoilla, kun himmentää. Eli optimi vehjes panoraamoihin.

I admit it happens for the first time in our tests that the results on the edge of the APS-C/DX sensor and full frame are, to an accuracy of the measuring error level, identical across the whole aperture range. What’s more important it is not the full frame edge which drags the MTFs down, quite the opposite is true, it evens the results on the edge of the APS-C/DX . As a result already at the maximum relative aperture these values amount to almost 30 lpmm so in fact are fully useful! Neither the Otus 1.4/55 nor the Sigma Art 1.4/50 by f/1.4 reached full usefulness on the edge of full frame.
The situation only improves on stopping down. Near f/4.0-5.6 the image on the very edge of the big full frame detector is simply sensational as the MTFs noticeably exceed 40 lpmm a noticeably better level than that of the Otus and the Sigma. We haven’t seen such a good performance on the edge of the frame for a very long time.
The idea behind the Milvus 1.4/50 becomes clear now. It is a lens which was supposed to provide an excellent image quality in the frame centre but without any record-breaking excesses, those are within the scope of the Otus devices. Instead you get a brilliant performance on the edge of the frame - in the range from f/2.8 to f/8.0 the images are excellently sharp practically across the frame. Mind you you can have it all for a price two times lower than the price of the Otus.
Olen ollut lukevinani, että Nikonin uusi 24-70VR on myös suunniteltu tasaisemmaksi toistajaksi koko kuva alalta mitä edeltäjänsä, siis vähän jopa keskiterävyyden kustannuksella.
