Hi Jialong, thanks for reponding, now you made me make my 2nd post.
Most of the time the events happen in late afternoon after 4.00pm, when the light starts to dim. But on good days when the light stays later, I can still maintain higher shutter speed of 1/200~1/250 or even higher. The 55-250 at 150mm or above can isolate my subject pretty well, but the pictures as a whole just aren't as sharp as I would like them to be, comparing to works I saw in publications (I'm just afraid that my eyes are spoilt now, wanting to see sharper images). I tried going nearer to the very fast moving subject, it's easier to capture better images than when I was further away from it, but there are some angles and compositions that just won't allow me to do so... that said, even the 'sharpest' image that I got so far, though not far off IMO, are still not as sharp as other works that I saw no matter how hard I tried, I'm doubting my own ability , pretty sad now. So I feel like a "frog-in-a-well", not knowing how 'wonderful' all the lenses are in the market that could help me, or did I buy a wrong camera for my intended application in the first place? Although with limitations on my X3, I'd still like to explore it's 'hidden' potential that I may not know, by attaching 'better' lenses on it maybe? I'd seriously need some advices here. Thanks a lot, man!
