... I tried out Fa135 f2.8 a while back and its AF speed is incredible but its purple fringeing rendering to images is just too much to bear...
That is interesting. I have used my FA 135mm/2.8 a lot, and dont find such problems. Or is it only me and my eyes? What other FA135/2.8 users think?

I have found this lens being very sharp and having good contrast in *ist D and K10D. I cant find any purple fringing....

Usually purple fringeing is obvious after blowing up the size of image in prints. 5X7 inch would be large enough to see the fringe.

I posted a thread showing the fringe before. Though I love the sharpness of this lens and its AF is way much faster than Fa 77 ltd

I had both lenses and compared the AF speed, and found the 70mm to be much faster. As for IQ, I still prefer the bokeh from the 77mm.
