I have a couple of Canon L-series lenses for my rig and a buddy of mine's 11 YO son wants to take up "wildlife photography". I let him use my 100-400mm L and of course he loved that... His dad has a Rebel and wants to get him an inexpensive longer-range zoom to take pictures of birds, deer, etc. while he practices. Money is a huge factor and at this age he does not need a $1000-2000+ lens.
Question--are there any kit-priced lenses that would do a decent job out to 400mm that the kid could have some fun with and once and a while get a great shot? I don't know this end of the market and could use some advice. Non-Canon is fine in this case.
Thanks,
Sean
