Bought this to go with my brand new A7III as I wanted a standard prime to go on it when I put the camera in my messenger bag. As tempted as I was by its bigger brother the 50mm f/1.4 its a much larger and heavier lens and not as practical for just tossing in your bag and carrying around with you
Optically its fantastic, Sharp as a tack and has excellent color and contrast right from the gate at f/1.8 which is very impressive. The Bokeh, while a subjective thing, to me brings to mind my Sigma 50mm "Sigmalux" which has legendarily good bokeh. The more expensive and heavier f/1.4 is better due to the extra aperture blades, but again, its at the cost of significantly more weight and bulk. A lot of reviews have trashed this lens VS its bigger brother but I think its honestly unfair, and in my opportunity to test both of them side by side honestly, there isnt a huge difference between the two of them, especially when you account for the huge price differential. The lens has so far done a marvelous job and delivered multiple shots with fantastic color and sharpness for me, The autofocus is extremely fast and accurate on the A7III and I've had little to complain about.
Build wise the lens uses a lot of metal and screams "quality", the lens hood is likewise metal with a slight rubber coating on the end of it where you might knock it against something, a really nice touch.
If I had to complain about anything, id say i dislike the minimum focus distance and maximum magnification, but thats pretty much equal for all 50mm lenses across the board, simply put, i wish the lens focused closer and had a bit more in the maximum magnification department. But again, No other 50mm-class lenses that arent macros do either so its not something I see as a big deal.
Oh and Sony's rear caps kind of stink compared to well..everyone else ive ever used (Nikon, Canon, Micro 4/3) I dont know what it is about them, but I dont like them very much..
Overall though, those are very tiny complaints and I feel this is probably the best general purpose 50mm-type lens in Sony's lineup right now. Dont hesitate to get one if you're in the market for or want a lens in this class.
