I like both 35mm and 65mm rendering actually. Cat eyes is disappointing but I don't expect they can get these right as size is priority. I haven't seen many lenses free of cat eyes problem. Onion ring is never a big issue for me as long as they are not aggressive.
I especially care 35mm rendering. Like many for 35mm, I don't need bokeh quantity but quality. More blur is not as important as smooth neutral rendering of scene. I think this sigma is at least as good as Nikon 35mm S in my eyes which is my 2nd favorite 35mm lens in term of rendering next to RX1. I don't need see more reviews myself to know this lens is a good buy. The Samples are enough for me to draw conclusion.
To my surprise, both are actually very high performance glasses. Cherry on top. It is so pity sigma FP doesn't have flip screen, otherwise FP with a few Contemporary glass is awesome setup for arm length shooting. Maybe get a S5 myself for that role, even I don't need a viewfinder
It's early to say but from the images I've seen so far, I don't see that super smooth transition zone the 45/2.8C is famous for, and that goes for both new 35mm and 65mm lenses. We should know more as more images emerge.
Having said that, I think they do better than the current options. Perhaps Sigma corrected SA a bit more for their faster f/2 lenses, which could mean more accurate focus at close-distance. (less SA)
Perhaps the 24mm will complement the 45/2.8 in look.
THere is slightly trade off I can see in term of optic performance and rendering. If you look MTF of both glass, they are in another league compare to 45mm. 45mm has one of rare balance in modern glasses, it has little CA, minimal FC and consistent sharpness even with SA. however, it will never offer super crisp sharpness even stop down compare to other top glasses I have but I don't really need that for it.
For both 35mm and 65mm, they are tilt to the balance of more toward to raw optical performance, in the meantime, it keep relative good looking background. I especially like Sigma pay attention to LaCA and LoCA for their budget line. Nikon did the same thing on their f1.8 line where Sony fail to do (in my honest opinion for both 35 and 85), I just care this much more personally than onion ring or cat eyes, especially WO shooting, I hate those bokeh fringing in far away background such as mountain and horizon line etc...ZM35mm f1.4 is another strong offender here come to my mind. This is also the reason I am quite disappointed with Panasonic new 85mm f1.8. It is just not enough somehow. I always have doubt about that lens since I preorder it anyway but samples were not good enough, especially compare to Nikon f1.8S one, this really frustrated me. This make me instantly put down my hope of their f1.8 line actually.
I dont know others, but most glasses can turn me off just by viewing DPreview samples. I do see a few extreme corner nervousness in 35mm images, but I know where I should limit my expectation
