Your right, my fault, it says it takes advantage of the in-camera image stablization... here's the copy from sony's page...
An ultra-bright standard lens for fast, accurate shooting by available light. For quick candid shots that capture the special moment, the SAL-50F14 lens provides superb clarity and visual accuracy, even when shooting at fully open aperture indoors, in low-light or twilight conditions. Mounted on your α (alpha) DSLR-A100 camera, this lens provides midrange telephoto 75mm focal length (35mm equivalent)-and takes advantage of the in-camera Super SteadyShot® image stabilization system to minimize blur from camera movement.
Superb Sharpness in Available Light
In conjunction with the Super SteadyShot® image stabilization system of the Sony ± (alpha) DSLR-A100 camera, this lens achieve pinpoint sharpness even working with hand-held camera by available light.
Bright f1.4 Aperture
The ability to capture more light in dark environments gives you a superb lens for hand-held shooting without flash, to preserve the mood or in locations where flash is not permitted.
Circular Aperture
Conventional lenses close their apertures with blades that can create multi-sided shapes -- but the aperture blades of this superb wide-angle lens form a near circle at the wide openings youll use for low-light shots, so spot-light sources have a pleasing circular defocused effect.
Here's the specs given for the Minolta, no age though...
These are becoming very rare to find. Minolta maxxum AF 50mm f1.4 prime lens- One of the fastest and best quality portrait lenses around. This is the original metal barrel AF lens, not the plastic version. Works like new and the optics are good, free of scratches, blades snap fine and are free of oil. Excellent for portraits and low light shots. Comes with both original front & rear lens caps, UV filter and its hard case. In good condition-light signs of wear-consistent with a lens of this age. Functionally perfect. Will work on all minolta maxxum cameras and sony alphas- A100, A200, A300, A350 and A700.
Do you think this statement is true for the Minolta? "One of the fastest and best quality portrait lenses around"
My intended use will be for quality portraits.
Thanks
