Just was taking a look at the 5D MKII and the general cost for it seems to be around $4,500 including a 24-105mm lens. The body alone is $3350.
The 18-135mm lens on its own is ~$699. That comes to $4,049, and has a longer zoom range on the lens.
How does this work? Do people pay more for convinience? Or will the stand-alone lens be of a lesser quality?
