Nice lens. Not too big and not heavy with a very good build quality.
Possibly not quite as crisp IQ-wise as the Sigma 85 Art however the difference IMO is negligible.
I have yet to find any CA at all.
Price is attractive in comparison if you shop around and the VC is a bonus as well as AF that initially appeared consistent however as I looked further into the AFMA using Reikan Focal it quickly became apparent that this lens has a focus shift issue. This has been mentioned in other non-POTN reviews and it is by no means a subtle issue as the variation in AFMA values throughout the aperture range is significant.
In a nutshell my copy of this lens front focusses wide open and back focusses stopped down and I don't think it's a fault, more a characteristic.
The range of values from f1.8 to f6.3 is +15 to -7 respectively in my copy of this lens. I didn't stop down any further as by the time I had finished the range that I did I was losing the will to live - it's time consuming.
However all is not lost - well I would say that would I not, seeing as how I have purchased one of these - as the actual images produced are very good. I have set my AFMA value at +6 but where focus is absolutely stonkingly critical then I'll use live view on my 1DX. I'm not a pro but I expect occasionally I will use live view for when I think I need to.
At approximately 1/3 of the cost of the new Canon 85mm f1.4 it's good value as long as you can live with the focus shift. I have not decided whether I shall keep mine or return it as I haven't had it long enough.
I've posted a couple of examples, neither is very exciting, more later if I do in fact keep it.
Follow up: After extensive real-world tests, ie I took a fair few photos, around 220, and spent quite a time checking out the results I have decided to return the lens as I found I was faffing too much changing settings on the move. I have still given an overall rating of 8 mainly because the results were good when everything was set right but I can't in all honesty recommend it as confidence is low as they say.
