i was fortunate enuf th snatch this for about $ 250 on e bay....... a friend played with the 57mm 1.2 briefly and instantly wanted one ,the next one he saw on e bay was like $500. yikes!......... the adapter is solidly built and finished and compliments the lens well .
It came to me in excellent condition all glass clear and clean, barrel in excellent condition a little shy of mint , the konica uv filter has some very tiny marks otherwise it was all good
shooting thru the filter seems not to show the near microscopic marks in the image ,but ive not checked too closely yet for them yet
i took it out in the day and it seemed just so much overkill, its a heavy lens , not crazy heavy, but noticeably so , as the meter called for f 8 and 11 , it seemed to me i was haulin this gem around for no reason , as the tiny contax g 45 f2 sat home unused
in the evening its a different story, by steetlamps i was shooting at at 1\80../. 100.. 250 of a sec!! holy moly.... i never experienced this before at lower iso`s, its a treat.
it really makes a difference over my nokton 50 1.5 a somewhat sharper lens wide open
but the 57 1.2 is plenty sharp for its speed much better than i had hoped,.. indoors without a flash this lens shines as well
ill post pictures shot with the lens shortly
