comment:I bought this lens a good few years ago to use with my film cameras and was always happy with it.
When I got the a100 I found it not quite wide enough and changed over to the 16-80 zeiss via the 24-XXX zooms.
Since getting an a900 last year , after working my way though my lens collection , this is back to being my walk about zoom lens again.
It feels very well balanced on the camera , a good build quality and feel.no zoom creep etc.
Range wise , 28mm on film/full frame is wide enough for general use without adding any noticeable distortion ,likewise 105mm is a good reach for most use . Close focusing is good at this range too with nice bokeh at the long end.
Colour and contrast is nice and rich , typical of the early Minolta lenses , rendering the images very much to my liking.
Sharpness is good throughout the range and is useable wide open.
I find it of more use in low light than my KM 28-75 f/2.8 and early Sigma 28-70 f/2.8. Both these lenses need stopping down a bit to the point where I can just use the 28-105 wide open and get better image quality .

Overall , if you can get the RS version , I would recommend you get one . Best used on full frame or film , but has it's uses on apsc .
There are two other lenses of this range , the original one with the smooth focus ring , and the xi one . Compared to them it is a bit better than the previous one with better brokeh , and much better all round than the xi one.

Edit ; very slight barrel distortion at wide end I have only just noticed ( on full frame ).
Nothing really to note , but it might be an issue for some users . Up till now , nothing I have used it for has shown this up .
I would give it a 4.5 if able to .
