Super zooms are intriguing lenses: nearly all focal lengths you may need into a single lens! But often, the price to pay is a so-so image quality and cheap built quality. The Canon 28-300 is an unusual super zoom: Nikon, Olympus, Sigma and Tamron offers lenses with similar range, but the specs are very different from the Canon. The 28-300 L costs four times more than any other superzoom, it weight three times the Nikkor 18-200 and it is twice as long. That's not all: it is also the only superzoom that offers weather sealing, professional built quality and push-pull zoom. All these peculiar characteristics make the Canon 28-300 a pretty unique lens! I already tried it in the past when I published the first short review, but now I have had the opportunity to try it for some weeks and to write a more in-depth review, with tests and samples.
