My birthday is coming up and I am looking at getting a new lens for my Canon camera. I have a few consumer lenses (28-135 IS, 75-300 IS, 50 f4) but after the last Blue Angels shoot, I have come to the conclusion that I need to have at least one good long high end lens and probably one good wide angle one as well.
The problem is that there are sooo many cool options. I played with the Zoom Telephoto EF 100-400mm f/4.5-5.6L IS at Glazer's today and it was pretty cool. The autofocus is much quieter, smoother and faster than the one on my 75-300 IS. The 100-400 is also sharper and, while we're at it, heavier. It is cool. Now I could also use the EF 70-200mm f/2.8L IS which is not nearly as long but it is clearly faster than the 100-400 and it should be sharper as well. They both have advantages and disadvantages.
User reviews of both of these lenses are very positive and either way it will be a clear improvement over what I have now, so perhaps I can't go wrong.
Then there are the wide angle zooms. Super Wide Angle EF 16-35mm f/2.8L vs. Super Wide Angle EF 17-40mm f/4L. I don't have anything that wide and I don't want to get the consumer lenses anymore but there is a pretty big difference in cost between these lenses. Looks like I've got more research to do.
