David Kilpatrick tested Beercan against Canon 70-200/4 L lens.
His conclusion:
"Most of all, comparing this lens with the relatively expensive and much larger Canon itís clear that the performance is either equal, or better."
Whole test is here

As much as I absolutely LOVE my 70-210 Beercan, enough to do this mod, Kilpatrick's test doesn't tell the entire story. The BC has a bit of field curvature which prevents super critical edge sharpness when using AF. I can get it with manual focus just fine. But the AF only wants to hit critical in dead center.

As well, that Canon f4, at 135mm has tests to prove it actually rivals the "L" 135mm f2. That's no small feat for a zoom lens. Alas, the low contrast colors of the Minolta are what pluck my heartstrings. They're just waiting for deep PP manipulation to squeeze the color out like juice from a cherry. Even if Sony updated this fine Beercan family, I'd have a hard time letting go of the one I have.

Good to see this comparison. Thanks for posting. It reminds me of one reason I left Canon and those clinical "L" colors behind. Yuck for skin tones.

It's nice to see that the Beercan can keep up with more modern optical designs. I'm shocked and pleasantly surprised by my results whenever I use it, and am especially happy that it keeps up with the dense pixel count of the a77. It's just such a perfect combination of image quality, size, and price.
