I use the 17-40 f4, 24-80 f2.8 and 70-200 f2.8 with the CANON 1Ds. Both W/A
zooms show barrel distortion and the 70-200 vignetting, wider than f5.6 and
pincushion distortion, though not too badly.
Expecting a 17mm zoom lens to show no barrel distortion seems a little optimistic to me. I have found this lens to be amazingly good considering its range and low price and would agree that Panotools will correct things but add to the workload. I compared the 16-35(?) f2.8 to a 24mm prime and found the newer zoom to be superior in every respect. Principally the prime showed slight fringing. The key seems to be to go for new design lenses. I believe Canon are improving their lenses to cope with the phenomenal potential of the digital cameras and so contrary to my original assumption the new zooms are in fact better than at least some of the older primes.
e 1Ds has a great chip but I dislike some of the functionality , the small
wheel by the shutter has too many functions, two wheels to adjust focus
points, the distortion on the lenses and the hard to use 550EX. The
solution would be Canon body with Nikon lenses and flash but I fear that's a
fantasy too far.
I was waiting for a Nikon as I prefer the feel if the lenses but must say I do not regret staying with Canon, although I have had to start fresh with lenses. The ease of handling of the Canon system was one of my original reasons for converting from Nikon some years ago and once the wheels are mastered it is far quicker than messing about on the top plate of a Nikon.
