Having a love in photography is like on a path of self-destruction. Just when I had enough time to test out my 60D after a nice photowalk in Lucidity, my itch for 5D Mark II got a lot stronger. Most forums are saying the difference is not as much as your skill set (well,…of course, but I long for that clean crisp IQ that 5D offers). Finally found a good page:

“Even at ISO 100, the difference is obvious if you view at 100% but unnoticble if you reduce the size said to 2000 pixels. but 5D color rendition is still better. IQ is not noise or sharpness alone but many other factors. You need to view a photo as a whole.”

For the lenses to go with the 5D, I decided on the pricier 16-35 f/2.8 since I prefer a wide aperture when I can get it, more freedom for candid shoot than the 17-40 f/4.
I was gonna stop there until I realized that I won’t have a zoom lens in the mid range for the 5D. I was already planning on keeping the 60d+17-55 combo. The IS on the 17-55 is a life saver and I really like the 2.8 aperture. The only problem with that with the “office” look that most comedy shoot are going for, I need a zoom lens that can provide a good range. I notice that I don’t like the look of 17-24 on a cropped censor for shooting video, especially inside because of the distortion. But then I cannot zoom much at all from 24-55. I need(?) a longer zoom range.

I started looking at the 24-70 f/2.8 but it doesn’t have an IS! even though I love the the aperture, I finally decided that a shaky handy cam look is worse than a high-iso desaturated grainy look. Then suddenly the 24-105 f/4 came to the light. I was really torn until I saw this review.

The bokah won’t be as big of an issue for comedy or general purpose shot. And for the dreamy bokah cinematic shot, I would definitely put the camera on a tripod and use the 50mm 1.4 so that part is fine. It really is just a toss up between keep using the 17-55 f/2.8 IS as it is and not use the 5D for mid-range video zooming or get the 24-105 f/4 and crank up the ISO (which would be less of an issue for the 5D anyways)…..

The word is, I will get the 24-105 (what a deal if you get it with the 5D!) and try it out…..
