I have tamron 90 and don't like it.. maybe it's just my sample but in manual focusing, while turning the focus ring you can feel stiff friction, kind of like plastic on plastic. it is also very loud.. it feels cheap too.

I wish I'd go for pentax 100 instead or at least sigma 105.

it also seems to have PF at borders in contrasty scenes, but i don't know if other 2 have it (i think some tests don't consider PF a CA for some reason thus all reviews list low CA)

hi all,

i saw there is a A 50mm macro f/2.8 manual lense, since it is A it is a newer version than 50mm f/4 macro right? 'A' means it can use on digital pentax with aperture mode.. but anything else that make this 2 lenses different?

how is the quality of that f/2.8? a bigger aperture isn't a must for macro but can be useful to use as some kind of potraits lense.

if both quality wise are the same, it seems the A 50mm macro f/2.8 should be a better choice as the price difference of 2 are $50-100..

any opinions? thanks.
