  • Tamron 28-75mm f/2.8 XR Di LD Aspherical IF SP AF

    5 out of 10 points and not recommended
    cheap, small, IQ
    mecanically weak

    I am a Pentax K10D user. I bought this to replace the kit lens.
    The first one had some kind of front/backfocus problem so it was sent back, the second i got after a week had some centering fault i beleive and now i am waiting for the third lens.

    I'we got my third lens and it was allright between 50-75 but between 25-50 very soft and the camera couldnt focus properly at distances over 2m on shorter distances i was ok. Even this lens was sent back.

    Now i have got both my camera and lens calibrated but it is not what i hoped for and not as good as the test here shows, its sharp in the center from f2,8 and from f4 its almost sharp overall but the contrast i not what i have expected.

    They who have problems with sharpness with this lens I would reccomend to calibrate both the camera and lens.

    After using my lens for several months now i have reeditet my review, the lens overall i a dissapointment, its useful but nothing to rave about

    I belive that the quality is very uneven, there can maybe be good lenses but there are many poor lenses too.

  • Tamron 70-300mm f/4-5.6 Di LD Macro 1:2 AF

    9 out of 10 points and recommended
    Very good at f8, small and light
    purple fringing, soft at the long end

    I use this lens on a Pentax K10D

    After reading much reviews i found out that this lens can be veery sharp if you use it the right way and produces very good images.
    Mostly i use it at f8 and 70-150 where it is at its best.

    A very nice lens i can reccomend, its not too heavy and the feeling is really proffessional.
