It's certainly a big call, but that's how this reviewer described the new Tamron 20-40mm f/2.8 lens. Take a look to see what all the fuss is about.
With every new release of quality third-party lenses, I think Canon owners shift a little more uncomfortably in their seats. I certainly do, especially as an owner of numerous Tamron lenses, a company which I think just tops Sigma for best in the third-party lens making market. Of course, you might disagree with that assessment and offer up some very reasonable evidence to make a claim for Sigma or any other third-party lens maker, but what I don't think any of us can dispute is the huge leap in quality that third-party lens makers have made over the last decade.
And that brings us to this great video by Stefan Malloch, in which he reviews the new Tamron 20-40mm f/2.8 lens for Sony E mount cameras and goes as far as saying it "just might be the best walkaround lens that there is." Its versatility and lightweight design are big pluses, according to Malloch, as well as its very affordable price of $699. One thing that's quite unique and interesting about this lens is that at 40mm, it is at its most compact, but as you rotate down to 20mm, the lens extends, as if it's almost backward engineered. However, I don't want to spoil everything for you, so take a look, and let me know your thoughts. Is Malloch's assessment fair, do you think?
