I am planning a trip to Australia and New Zealand and need to upgrade camera bodies. I currently have a 10D and a 20d. We have 3L lenses that we have been using since film days (circa 2001).
16-35L, 24-70L, 100-400 IS L and a 1.4 extender. Also have a 50mm prime lens and cheap kit type zooms from 1999.
I could trade in one of the old film bodies through the Canon loyalty program on a newer refurbished body.
We do a lot of landscape and wildlife photos when we travel. Should we go for a full frame camera on the upgrade? Are these lenses still considered "quality"
Those are definitely some very good lenses, although the 24-70 does not have a good reputation for maintaining calibration, so it may need servicing. Landscape sounds like a good match for full frame but not wildlife. A lot depends on how close you can get to the wildlife and if it is moving or not. If we are talking about getting close to a perched bird, then a full frame camera, like the 5D Mk2, will be fine. However, for typical 'birds in flight' type action, something like a 7D would do much better.
Also, keep in mind that the 1.4X extender will only auto-focus on the 100-400L when used on a 1D series camera (except the new 1DX). The aperture of the 100-400L is too small when combined with the 1.4X extender to AF on a 5D Mk2 or a 7D.
