For the last 35 years I've been shooting 4x5 and Hasselblad. Using the best lenses in both formats (I class in Hassie).
Just recently I bought a new Canon 1DS Mk II with the 16-35 L, 24 L TCE and the 70-200 L Canon lenses. All purchased brand new from Calumet and B&H.
This past weekend I finally had time to run tests on the 16-35 and the 24 lenses. I am very distressed with the resultant POOR quality of these lenses compared to what I've been used to. Canon should be ashamed of these lenses!
I took a real workd scene - waterfall, rock cliffs, trees - and set the 1Ds up on a tripod. Using the remote I shot one frame of every aperture. Came home, downloaded the images into Lightroom and began to study the results.
I was disgusted to find there is no aperture for either lens that is sharp in the corners or across the borders!! Identical for both lenses.
Forget sharpening filters - it just can't be corrected properly.
Now, I do find the fidelity of the array in the 1Ds decent and I'm wondering if the 50, 100 and 150 I class lenses I have on a Hasselblad 503CW would work on the Canon. Has anyone tried this with success?
PS: I am so disgusted that I plan to add a page to my web site with cuts of the test images so anyone contemplating these lenses can have a look to see what they will get for their money. Give me a couple of weeks to get to this addition.http://www.shadowsdancing.com
