Really lovely sharpness and bokeh. This looks like a lens I'd trust to stand in for and even better some primes.
@ Richard: Excellent sample image! Add some post processing and you have fine art and a great lens evaluation :-)
And i am really, really impressed with this lens. Object close to corner at f/1.8 and still very sharp considering open aperture. The charismatic aberrations can be cleaned up in post processing which will increase the perceived sharpness even more.
There are some very bright highlights and they show no any purple fringing. It is possible this thing is better than my 35 mm AL f/2. Really impressive!
does NOT have freakish looking corners .GREATi am sold. Just waiting to buy one :)
