My wife and I both shoot photos on our trips. We just returned from 3 weeks in China. Current equipment is
10D, 20D, 16-35L, 24-70L, 100-400 IS L and a 1.4 extender.
We also have a 3 film bodies, a few primes and lower level zooms that are gathering dust.
The next serious trip will be summer 2011 but there will be plenty of photo opps in the meantime. Are we really missing anything by continuing to use the 10D and 20D bodies? If an upgrade is in order, I would probably be looking at a 5D MKII and a 7D. Is this overkill?
Also, should we be looking at updating the glass? The 100-400 IS L is from 2000. The other L lenses are from around 2003.
