Conclusions

This lens is a good steady performer. Used well stopped down results are excellent, but in the test frames at wider apertures there are some weaknesses - More than I expected having used the lens for a month or so now - I’ve been very happy with the results.   For a medium priced full frame lens with USM I’d still recommend the Canon 20-35 f3.5-4.5 USM.
