Originally posted by bdery Slow AF on the 60-250 is an overblown issue. It's slower than the newest lenses like the 70-200 and DFA50, but it's not "slow", per se.
The optical is a 60-250 / 4 very grateful lens, a fantastic range, the size is acceptable (all better than the FA 80-320 ), the lack of the focus speed (nothing faster than the FA 80-320 - slow as DA17-70 / 4), the new ff lens with the aperture f4 and the approximate range but with a faster focus, smaller body and better optics would be a big blow to the existing 70-200 / 2.8 which does not have a small body, I doubt,
a shorter range of 60-250 as 70-200 / 4
with a faster focus and a smaller body but with weakened optics of 60-250 / 4, especially from 70-200 / 2.8
wil be the likely reality, I hope I'm wrong, and that will be a greater range of 70-200, faster focus of 60-250, a little body of 65-250 and optical as DA * 60-250 , of course with all and a price between 60-250 / 4 and 70-200 / 2.8 , modest and realistic
