Switched from an EF mount Sigma 100-400mm lens, and find this is so much more versatile and has slightly better image quality. Focus is a little bit faster & more accurate, but the main benefit is size and weight. IQ is a bit sharper and more pleasing, too, and it seems to auto-expose better on my Sony cameras. I don't really miss the extra 100mm to be honest.
Pros: - light, small - easy to carry around or have in the camera bag - good IQ, even without considering price - works very well with the Sony body, including in-body stabilization
Cons: - plastic - no zoom lock means it often extends when carried barrel-down - "slow" lens (narrow aperture) but completely expected given price point & weight
Highly recommended for a backyard birdwatcher or casual photographer looking to get a little reach in their photos.
(If you're curious about the birds, that's an Anna's hummingbird and a goldfinch that I think was either very lazy, overfed, or young. There was a female nearby working hard while he watched, and he wasn't a great flier).
