300 f/2.8 L IS, Sigmonster and 400 5.6L
Feb 14, 2006

Ever wondered how these lenses, though not in the same weight classes (if this were boxing), would fare against each other when shot side by side?

I did.... and this curiosity forced to me earlier today to drive over to my friend's place to borrow his 300 2.8 L IS for a shootout.

I actually did a test between the Sigmonster and the 300 2.8 L IS a few months ago, but in less controlled conditions. This time, I made sure that focusing errors would be minimized - I took 5 AF and 5 MF shots per setting and selected the sharpest pic.

Here are the crops:


Again, the results apply only to the copies I have used.
