  • Sigma 28-105mm f/2.8-4 Aspherical IF

    5 out of 10 points and recommended
    cheap, internal focusing
    large filter size, build quality

    I used this lens with analog Minolta 505 Si Super.

    Image quality is OK for postcard format photos.

    Auto focusing is slow, noisy and sometimes lens hunts to focus. Manual focus is not to precise due to looseness of focusing ring and small range of movement between infinity and minimal focus distance.

    Zooming ring is too tight and moves not to smooth.

    On positive side is internal focusing which helps using polarized filters. However due to filter size (72 mm) filters are rather expensive.

    Overall this lens is average but for its price (especially second hand) this lens is quite good.
