How do you define "beat"? Both lenses have their upsides and downsides.
(referring to the original Tamron 150-600 -- not this new one -- below)
The L is sealed, has better AF, and is sharper up to 400mm.
I appreciate the L with the 1.4x is comparably sharp as the Tamron on the long end, but the Tamron goes to 560mm without the teleconverter limiting the AF. At half the price.
So I could see fans defend either lens as being better given what their needs are.
