Roger,


Thanks for the comments, your right I need to be more careful cropping.


I've used my lens in bright sun, cloudy days, fog and indoors occasionally. What I have found is that on heavily overcast days, or close to sunrise or sunset, it can be a little challenging to get a fast shutter speed. I have shot some outdoor soccer early morning, on a cloudy day and I had to push the ISO to 800 or 1600. Which one to get is a very hard choice unless you are flush with money. If you are going to be more than a hobbiest, I would prioritize like this, apeture first, IS second. Last time I looked the f4 IS and the f2.8 non IS were very close in price. If that was my price range I would get the 2.8 non-IS, given the shooting priority is soccer.


However, if cost is a major issue, as it was for me, you can get away with the f4 non-IS, just know that there are limitations.
