p.5 #1 · The Lens is Not More Important Than the Camera
The lens and camera act as a team and any weakness in either will effect the end result. I do not really recall reading anyone commenting that the lens in more important than the body, however I have read many posts saying to get glass before a replacement body for a couple of reasons
1. Glass holds it's value longer than a body.
2. Getting a different focal length offers new composing opportunities.

I like to shoot macro with my 1Ds3 + 100/2,8 macro or Sigma 150/2,8.
what $ 600 body beats that combo
Or what what $ 600 body beats the 1Ds3 + 17-40 when I like to shoot superwide landscape
Or the 1D4 + 70-200/4 for sport
Hence the word extreme.... there are exceptions but there are things you can't do with shitty lenses no matter what body you have.

I used to shoot groups/teams with an old Yashica twin Lens reflex...google it if u have never heard of it. The center people were razor sharp and the edge people were not sharp due to what I think was spherical abberation.....Stopping down to f8 didn't even help. When I first went digital about 2001-2, I used a 20-35 f3.5-4.5 Canon which is a pretty cheap lens. Edge people were as sharp as the center people at F8. I also used a 17-40 L lens at the same aperture and i could not tell the difference in group pictures....Both lenses were great at F8.....So I will say stopped down, inexpensive lenses can match L lens. Wide open is where the L lenses shine but my group shots demanded depth of field so wide open was not desirable. In these cases, my D30 pictures were excellent...My new 7D would have a finer pixel structure and probably would look better at high magnification. There are a lot of variables as to what is more important.....I tell my kids in my summer College for Kids class on photography that the photographer and his/her use of light is the most important factor in a good picture. Editing in photoshop has helped me more in photography than any lens or camera. Sorry if I've thrown more variables in the question but it is more complex than just camera and lens....the mind of the photographer is critical in composition which is critical in the picture taking process.
I'm not saying pinhole cameras could match todays cameras and lenses but new digital cameras and lenses can all take great pictures in the proper hands.
