Roger at LensRentals.com has done a quick comparison of the EF 400 f/4 DO IS and EF 400 f/4 DO IS II as well as the EF 100-400 f/4.5-5.6L IS and EF 100-400 f/4.5-5.6L IS II.

“The difference in Canon’s computer-generated MTF charts for the 400mm DO and 400mm DO II is pretty striking, and I think our results confirm that difference shows up in actual optical testing as well as in the computer ray tracing. Canon also says the new design has much greater contrast, and I tend to believe that too, although we’ll all want to see images in a variety of lighting conditions.”

“The Canon computer-generated MTF charts suggest that the center of the image should be similar in both the old and new versions, but that the Mk II should be noticeably better off-axis and particularly in the corners. We do see that difference in the resolution tests, but I had expected the difference to be a bit larger. It’s certainly not nearly as dramatic as the DO difference.”

Bryan at the-digital-picture has completed his review of the brand new Canon EF 24-105 f/3.5-5.6 IS STM lens.
“As it stands, the Canon EF 24-105mm f/3.5-5.6 IS STM Lens is a nice lens overall. The size and weight of this lens are easy to handle for long periods of time and the lens shape is comfortable to use. For a moderate price, the 24-105 STM covers the full frame image circle with very good image quality. The modern STM AF system gets the job done nicely and the image stabilization system makes sure that camera motion blur is not detracting from that image quality. This is a good value lens.” ….
