Favourite lenses...40mm Limited F 2.8 Pancake...on both ASP-C and K1 DSLRs, 28-105 and 100mm Macro F 2.8 on the K1 and for film K mount...my A 35-105 Macro Zoom....a truly fine lens.
My all time favourite lens...probably my A 35-105 Macro zoom. I've used it on film cameras of course and also my digital. Pix taken with it, have a lovely quality about it...hard to explain...but a creamy background, great clarity and build quality out of this world....tank like and I mean that in the best sense of the word.
Another lens that I'm becoming increasingly enamoured with....don't know if it's merely infatuation at this stage.... or the real thing...is the 18mm (28mm) fixed lens on my newly acquired Ricoh GR ll. Externally it doesn't look too impressive but the results are exceptional from this wee lens.
So far my pix with this Ricoh are darn good...if at the end of the summer they continue to improve as I get used to it...the lens may move up to top status...which is @#$% good !
Pardon my vulgarity.
