Re: 24-70 2.8 L vs. kit lens...unexpected results?

I just went and compared the DXO measurements for these lenses.

Stopped down, the differences are greatly reduced - the wider aperture you go, the bigger the difference between the two lenses.

24mm at f/4 - there´s a huge difference between the two, more pronounced toward the edge of the frame but the L can shoot f/2.8 sharper than the EF-S can wide open.

35mm - f/4 v f/4.5 again the L kills the EF-s

50mm performance at f/4 matches the f/2.8 performance of the L, as you stop the L down to f/4, sharpness pulls ahead tremendously

70 v 80mm again, the L has similar performance wide open but pulls ahead dramatically as you stop down to the maximum aperture of the EF-S .

As you reduce aperture, the lenses perform closer to each other as to be expected.

The L does 3 things that the EF-S cannot - shoot wider, shoot at constant aperture and give you better subject separation. Sharpness is not the reason to buy this lens - contrast and physical ability is.
