the tripod picture was a test shot at the shop. i was shocked to see this

wasn't expecting this to perform this good. The AF-D was good but I don't recall it to be this sharp wide-open

the guy with the hat showed some veiling flare but not so bad really. the bokeh is very smooth! this is sharp enough to me.
at closer distances <1m, the challenge is to get things in-focus. some sharpness loss but not that much
the last picture is the minimum focus distance. very challenging to get it in-focus. same findings, small loss in sharpness at minimum focusing distance.
I took some portraits last night that I cannot share but it's perfect, sharpness and all (my subjects' faces) at around 1.5m to 4m away. i wasn't expecting this lens to be this good. mine might be a fluke. this lens feels like it's a bit delicate to put together like the 50/1.2 series so this may be the cause. very satisfied with this lens, no wonder it looked beaten-up when I got it. the previous owner shot and used this lens because he knew it was good.
