comment:Purchased used. I also considered the Sony SAL 35mm 1.8.
I opted for the Sigma because of the larger aperture, metal mount and 45mm versus 52mm field of view on APS-C (since on APS-C a normal lens would be a bit shorter than 50mm equivalent).
The lens is sharp from 1.4. Focusing is accurate in Spot & Local modes. Colors are well saturated and crisp. The lens is heavy and feels substantial in the hand but the plastic casing and hood , while adequate, could be more sturdy. I have not noticed any distortion. I have encountered lens flare.
The Minolta 50mm 1.4 is great but too long for some uses. The Minolta 24mm 2.8 is also a great lens but is too wide and slow on cropped sensor for available light shooting indoors. Neither is a normal lens on the A700.
The Sigma 30mm 1.4 allows me to unobtrusively capture images that reflect my natural field of vision. No compression of distant objects or stretching of edges.
The pictures look wonderful. The subject achieves an impressive separation from the rest of the composition. The out of focus areas are rendered smoothly and attractively in the background.
A used copy costs more than the SAL 35mm 1.8 brand new but much less than any full frame lens available new or used.
Bottom line - you cant blame your camera for not being full frame with this lens on it because the large aperture allows similar control of depth of field and lots more light to boost image quality.
It doesn't disappoint.
