300 f/2.8 L IS, Sigmonster and 400 5.6L

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.

Regards,

Romy
