  • Sigma 10-20mm f/4-5.6 EX DC HSM

    10 out of 10 points and recommended
    build quality, sharp, wide, low CA
    on pentax no HSM, not available the MF while in AF mode

    As I bought this lens to my Pentax K10D, I was surprised by the sharpness. It's better than the manual prime lens I own. The color reproduction is great on this lense. With the low amount of CA I'm also very pleased. The focussing is quite quick and exact.

    However, the Pentax version doesn't have the HSM motor and you cannot use the MF ring while in AF mode.

    Generally for the price I gave for it, this is really a great value youl'll get and actually till now it's the best lense I own.

  • Pentax 55-300mm f/4-5.8 ED SMC DA

    8 out of 10 points and recommended
    Optical quality, build quality, focus range
    slow AF

    I replaced old Pentax F 100-300 4,5-5,6 with this new Pentax 55-300. The optical quality is very nice also on 300mm , low CA, good in backlight, but the AF speed is very slow even in comparison with the old Pentax 100-300.
    Anyway I like this lense for the great focus range and optical quality.
