Background performance can be misleading if there is a periodic feature in it due to "spurious resolution". Spurious resolution

thanks. the reason why I ask is to see some consistency and more accurate representation. there are times that I see the the other lens is better at wide open but not so much stopped down. some of them seems to be not focused on the same image point for sharpness comparison (e.g. rose flower). this can be due to difference in DOF representation among lenses, but anyway could be better with more precise focusing. also the ST's bokeh seems to differ on the last image (maybe due to variable natural lighting condition. also I find the A50/1.2 sharper than the ST? also, can you tag each image of which lens were they take with? Thanks.
Sorry, Pentaxor, I never managed to redo the test like you've suggested. Partly because I got busy with the 35mm lenses and decided I didn't use the 50mm focal length much at all.

And now I've sold all but the Super-Tak which for the price and size is still fantastic and all I can justify keeping in this focal length.
