Myisin seuraavat Pentaxin objektiivit, olleet käytössäni K10D:ssä: SMC Pentax-FA 1:3.5-4.5 24-90mm IF&AL (* 270€ etu- ja takatulppa sekä vastavalosuoja FS: Pentax SMC FA 24-90/3.5-4.5 AL [IF] - PentaxForums.com SMC Pentax-FA 1:4 20-35mm AL 270€ Brief Comments SMC Pentax-FA 1:2.8 28mm AL 230€ etu- ja takatulppa sekä vastavalosuoja Brief Comments Tamron SP 17mm 1:3.5, model 151B (se uudempi), 170€ (ei sisällä Adaptall2 sovitetta) etu- ja takatulppa Tamron SP Adaptall-2 17mm F/3.5 Model 51B (huomaa, kuvassa vanhempi versio, teksti molemmista) Kaikki teknisesti erittäin hyvässä kunnossa, ulkoisesti 28millinen melkein kuin uusi, samoin 17millinen, kahdessa muussa hyvin pieniä käytön jälkiä kuoressa ja vastavalosuojassa. *) En saanut linkkiä Stanin sivuille toimimaan, joten tässä koko teksti: "Raimo - I just got my hands on the new SMC Pentax-FA 3.5-4.5 24-90 IF & AL. Looks quite good. Externally the mode of construction is similar to the current way of doing these things which means internal focusing (front lens does not rotate), no window over focusing scale and all plastic (except the lens mount, and glass). It appear to be very well built, better than Sigmas and even the 28-70 FA AL. It is quite chunky but handles well with MZ-5n and battery pack Fg. Manual focusing is well damped but the ring is thin - and it is VERY varifocal. It is quite light, too. . . [and a follow-up comparison from Raimo: this lens vs. the A 35-105 . . .] . . . The lenses have quite similar quality, the 24-90 perhaps having a little bit more contrast and sharpness. The difference is not big but the new lens is much lighter (due to more plastics) and much more versatile. The 24-90 is my new favourite, expensive but worth it. . . .24-90 is very good for general photography, for travel e.g. [and another comment from Raimo:] IMO Pentax 3.5-4.5/24-90 AF is a very, very good lens, but a bit expensive, though. Useful focal length range."
