Latest Review Posted | SMC Pentax-M 100mm F2.8 On a K10D my comparators for this lens are the Pentax DA 35mm f2.8 Macro Limited and Voigtlander Nokton 58mm f1.4, in which company the 100mm does pretty well (as far as I can tell, only had it a short while). Even though it is a recent purchase, this is a lens I can already see no reason ever to part with (unless I ever find a mint 'A' version)
It was purchased primarily for portrait shooting with increased working distance over the 58mm Nokton and came up at a price too good to ignore (mint £79 in spring 2013). An 'A' variant would have been nice but certainly wouldn't crop up near that price these days in the UK. An 85mm would maybe have been a nice choice but they usually cost considerably more. So in terms of value the 100mm M is very good indeed
I use it mostly used at f2.8 / f4 where it offers shallow depth of field and okay (fussy, definitely not outstanding) bokeh. Resolution is lovely for portraits but I would say this is not a high resolution lens in the terms I am used to, not even at f8. Strong contrast does cause some minor fringing issues, especially wide open but for portrait use it isn't an issue
couple of early images at f4 (note shallow depth of field in both and fussy bokeh in forest floor image) Some post process here as I messed up M exposure (RAW not on AND Green button not pressed - doh!)
