Canon EF 24-105mm f/4L IS USM

24-105lisusm
Review Date: Nov 26, 2005 Recommend? yes | Price paid: $1,249.00 | Rating: 7 

 
Pros: focal length range, IS, build, very quiet USM
Cons:
distortion at 24mm, too soft above 70mm.

I sold my Canon 24-70 2.8L before getting this lens. What a mistake! The 24-70L beats the 24-105L hands down. The distortion at 24mm is unacceptable for a 24mm focal length.
The softness I am seeing at 105mm is due to front focusing. At the price paid and the slow F4 aperture this is inexcusable from Canon. This lens is being used on a 1DMKII CPS calibrated body. I will definitely have this lens calibrated.
I like the zoom range, the Canon color quality and build. The focus doesn't hunt. I must express overall disappointment with this lens at the price paid.


 
Sigma 150mm f2.8 APO Macro DG EX HSM

Review Date: Jul 28, 2005 Recommend? yes | Price paid: $539.00 | Rating: 10 

 
Pros: Quality optics. Professional build. Tripod collar and lens hood included. Full time manual focus available that is smooth and precise.
Cons:
None so far!

This lens is a best buy for the price! it compares favorably with my Canon 180L Macro and is better optically than my Canon 100 Macro at 2.8. On the 1 series bodies it balances beautifully for handholding with the bonus of quick tripod attachment. Sigma did it right with this lens!
