I currently own a Canon 40D, but have thought of getting a backup camera. I realize the age of the Canon 1ds Mark II and its features mainly fullframe and the price of a refurbished unit at bhphoto is within my range. Or, do I go with another unit such as the 7D. I am not into the HD video on a handheld camera, feature that I would NEVER use. That feature belongs to those who likes to use handheld camcorders. Is it worth it to step back to this fullframe camera. I have the lenses for it, so that cost is already handled.
If I were you, I'd for sure go with the 1DS MKII. NOTHING beats a full frame and imho, the image quality you get from the 1DS MK II is far superior. Not to mention the built in grip, back up memory card and everything else.
That's a great question gren--I have been trying to decide this same question "crop vs. full frame" for a while myself. I would agree with Jay--just based on specs and not having used one. I've been looking for the 1ds Mark II or the 5d classic as both of these also fit my price range. I am still not sure about the necessity though as the my 40d does a great job. My lenses allow 16mm through 560mm--with the crop factor included. I think that my quest is for a lower noise and perhaps even wider field of view.
Recently had this lens fixed due to a problem with the Autofocus (warranty). Anyways, took some photos with it using my Canon 7D and they looked very sharp and crispy. Very nice lens as I expected. Now, the problem I had this past weekend when I printed one of the photos on my large format PIXMA Pro 9000 onto a 13x19 glossy paper, it looked very sharp, but I noticed a whole lot of softness toward the outer edges of the photo. This was a daytime photo (around 2:30PM) with the sun behind me. I have a polarizer filter. The settings were at f/3.2 -2/3 at 1/2000 using it in Landscape mode. I was somewhat discouraged by the softness. How can I correct this the next time I take this photo, at the same location, as long as the weather is sunny and scattered clouds.
