I just picked up a like-new copy of this lens, and so far, am loving it.
One the positive side:
1. Solid, Beautiful lens.
2. Image quality is great!
3. Zoom is a huge advantage over prime 300. I can cover home plate and first base from the same location.
4. Internal focusing, and zooming.
On the negative:
1. Heavy, more than a 300mm f2.8 prime.
2. Focus does not seem quite as fast, well vs my Canon 70-200 f2.8, which is VERY fast.
3. Zoom ring requires some effort. You can't spin it with one finger. it's big.
