|comment:||There have been several reviews on this lens previously. But I believe I am the first one reviewing it on A900 full frame camera.|
This lens will surprise you! It has been discontinued and selling cheap. However, its IQ is almost as good as Sony 24-70mm ZA!
It is a shame that there are currently no good travel lenses available for A900/A850 FF camera. The IQ of Sony 24-70mm is great. But it is expensive, heavy and bulky. It is also not long enough in many occasions. Minolta 24-105mm (D) seems to be a great choice, until you find the terrible light fall off and subpar IQ when aperture is wide open. Minolta 28-135mm is better than 24-105mm in terms of IQ, except that this old lens has disastrous flare control, and does not focus close enough. I tried Tamron 28-300mm Di LD. Its IQ also disappoints!
I finally tried this 24-135mm lens. I am very surprised that it works so well with the FF DSLR! The distortion is small at 24mm. The resolution is good even at wide-open aperture, and really excellent at f5.6~8.0! The color and contrast is vibrant. The performance on the corners is also more than acceptable on FF images. It is not digitally optimized, but flare is controlled very well. To tell the truth, just stopping its aperture down by 1/2~1EV, I already can't tell the differences taken by this lens and 24-70mm ZA in the same focal range!
The previous reviewer says that the focus ring rotates during focusing, which I do not think so. It protrudes out during zooming, but the front thread does not rotate during AF.
I wish this lens could be slightly smaller, and larger apertures (like f2.8-4.0). Maybe I am asking too much! Although it is not a perfect lens, this is the best lens you can get so far for travel or everyday use on Sony FF cameras!
