Nice 10x zoom lens. But no match to the Canon 28-300 L. Even the Tamron SP 200-500 outperforms this lens easily in almost all tests i did.
This lens weights a lot, due to a lot of glass inside.
If you look for an easy to use, affordable superzoom lens that delivers quality, this is your lens. With a smaller pocket the starters superzoom will be an option. A bit more to spend, take the Canon 28-300 L This lens is much better, but doesnt have 500mm. In need of 500mm, the Tamron is much cheaper, much lighter & with better results.
