Absolutely. The 1.3x is helpful for wildlife (turning my 400 f/5.6 into a 520mm lens) but does not destroy wide-angle capability, either.


For example, a 10-22mm lens becomes a 13-29mm lens. That IMHO is not bad.


I doubt you would notice the difference in angle, unless you HAVE to shoot 10mm landscapes.


The 1D4 is more expensive for a reason: better weather sealing, better-rated shutter, better ISO performance, ridiculously better AF (45 pt. vs. 9 pt.), and a whopping TEN frames per second. The 5D2 doesn't come close. IMHO, despite the 1.3x crop factor, if you can afford the 1D4 (I can't), don't think twice about buying it. The resolution of the 5D2, well, doesn't matter. You could do just fine with a 8mpix full frame camera. Megapixels, to a certain extent are marketing tools that deceive customers. oh well.[H]





Hope this helps...
