|comment:||I've just got it last week. After done some field test in reallife situation, it performs impressively.|
Many people say that this lens is very soft at wide open. Contrastly, I found that if the focus plane hit the correct position, the image will be very crisp sharp (with a bit dreamy soft effect at F2.8). For distortion, I think this lens rarely has it. Comparing to 235 AF II, distortion from 235 AF Pro is so far better than it's little brother. CA will often appear at every light situation by setting aperture to F2.8 and will be almost gone at F5.6.
In the same range as 270AF, it obviously lag behind the 270AF in term of sharpness at 2.8 and become closer while stopping down, finally as same sharpness as at F4 and above. That is only concerning of sharpness. For CA, no doubt, the 270AF beat it at every setting.
I just finished my test of this lens against AT-X 235 AF II

ps. I provided information in both Thai/English version. Enjoy reading.
After I used it with my A900.
F2.8 is terrible, CA is toooooooooooooo much and can't be corrected easily. At the corner of the image is terrible too.
Ah.... I miss my old AT-X 235 AF II T_T
