I currently have the kit 18-135 and the efs 55-250, both are working well for my family events and family/grandkid sporting events. A little more speed would be nice at times, but not enough to justify going to the 70-200 IS f4 or f2.8 options. A few years ago we were planning a vacation and for that the 100-400L was on the short list but plans change and the budget went elsewhere.
We're now planning another vacation so I'm back to lens option shopping. I'd like more reach with acceptable resolution for birds and wildlife and general vacation shots. I don't believe that I can use a converter with the 55-250, otherwise I'd try to find a 2x converter.
What other options do I have that I probably don't know about. Right now the 100-400L version 1 is out of budget reach. I figure that right now my limit is probably $300 which won't go far. I could sell the 55-250 but that would only add $50(trade-in) to maybe $100 (on craigslist on a good day, maybe).
So, what is a good option to consider? In the mean time I'll be practicing my foot zooming and wildlife stalking skills.
Thanks for any ideas, or links to other threads that I haven't found yet.
