Best Of

In Canon crop format, I have both a Canon EOS 7D (first version) and an EOS 80D, plus I bought 2 - EOS M50 mirrorless bodies more recently.

I had been using an older Sigma 10-20mm f/4-5.6 EX DC HSM as my super-wide APS-C lens for architecture, interiors and vista landscapes. It's a pretty good lens but I decided to keep it as a backup and replace it with a Canon EF-S 10-18mm f/4.5-5.6 IS STM. (It adapts to the M50 bodies using a Canon Mount Adapter EF-EOS M, preserving autofocus accuracy and speed, and IS function as well.) It's definitely a "kit" lens with no weather seals and a plastic mount, but optically it performs nicely.

I don't have anything using the EF-S 10-18mm f/4.5-5.6 IS STM worth showing, but PBase has some examples.

The-Digital-Picture.com has a good review for the EF-S 10-18mm f/4.5-5.6 IS STM:
