>>3625526>Pantecks made some nice K mount lenses back then.pic related, this is ~$300 of glass and everything except the goofy third party 28 ($5) and the 80s budget 135 ($10) looks gorgeous.
Pen-A 50/2.8 Macro is razor sharp; nearly as sharp as a modern lens.
Pen-K 300/4 is reasonably sharp at F8, gives delicious creamy DOF at F4, and handles like a beauty
Tak 135/3.5 is very sharp and built like a champ
Tak 55/2 is new to me, not really sure what to think, not sure it was really worth getting but it was $50 so not like I broke the bank
Pen-M 50/1.4 is swirly and painterly at 1.4 and reasonably sharp (though far from clinical) at 5.6
Pen-M 50/1.7 is similar except with less of the swirly painterly end (duh)
"Takumar" Bayonet 135/2.5 is goofy and seriously flawed but I kind of like it anyways; wide open it's got horrendous abberations etc, but it's kind of a neat look (almost like a soft-focus lens) and it stop down okay.
>>3625527woah, sick diy framing mat.
