Personally, I was very disappointed that GPS was not included with the 5D. I was really expecting my next camera to double as a SatNav system for my car as well. Ah well, maybe the 5DmkII will include the long awaited Matter Transporter so I won't even need my car. Damn Canon for their lack of technology. ;-)
Anyway, back to reality. This forum may not be very active, but it's great to have a forum where the people here are actually PHOTOGRAPHERS and not just argumentative techno-freaks.
I did get a 5D last week, though I have to wait till next week for the Ee-s screen to be available in the UK.
I have actually found it reasonably easy to manual focus with the Ee-a, certainly more so than the 20D with original screen, I'll see how I find the Ee-s, and if not much of an improvement, go for a Katzeye when they're available.
For those who want to use Zeiss C/Y lenses on the 5D, I thought it might be useful to know that although elsewhere it has been said certain lenses can't be used (85/1.2 135/2) I have use all my C/Y lenses (listed below) without issue, and without the need for modification to lens or mirror.
21mm f2.8, 25mm f2.8, 28mm f2, 50mm f1.7, 85mm f1.2, 100mm f2.8 Makro, 135mm f2, 28-85mm f3.3-4, 70-210mm f3.5, 100-300mm f4.5-5.6.
I caught this rather pretty moment on Monday evening near my home. The .jpg couldn't handle the full exposure latitude, but using the same frame in raw I created one underexposed and one overexposed .tif and combined them. This 5D's raw latitude really is impressive.
P.S. On the original raw/tif at 100% the window frames can be seen on the biggest white cottage!
