For an all in one superzoom, this lens performs really well. OK it won't stack up against the likes of Canon L glass or Sigma Art lenses but the IQ is very good and it certainly punches above its weight. Great for travel and if my main wedding lenses ever failed then I'd happily grab the 18-300 (it'll go on my EOS R with the adapter or I'd just stick it on my EOS M5 as the resolution would be better on the M5 as the crop mode on the R does reduce the image resolution to about 11 MP as opposed to 24 on the M5. A perfect lens for travel rather than carrying different lenses when weight is an issue.
