| price paid: | 350AUD (new) |
| positive: | Great old lens pretty cheap, even when new |
| negative: | Not as sharp on digital as it was on film. Rubberised coating tends to fail after about 15years. |
| comment: | I have had this lens from new, one of my original set of AF lenses when I moved to Minolta AF gear. I would rate its sharpness as 4.5 for film, but less than that on digital (probably better as a 4.2 rating overall). It disapoints a little on digital as does the Tokina compared to. But colour and bokeh is good. Overall the Minolta and Sigma compared to do a better job. When new I thought the rubberised finish was great, but a couple years ago it started to deteriorate and I had a tough time removing it as it got sticky as it deteriorated. Hence the 4 build rating, otherwise a tough lens. Also seems to have more flare issues on digital than on film, hence the 3 rating (probably should be 3.5). Needs to be used with a hood for best flare and contrast, especially on digital. |
