Image quality test results from the EOS 7D Mark II have been added to the Canon EF-S 10-18mm f/4.5-5.6 IS STM Lens review page.
The EF-S 10-18 is a very good value, with decent image quality, very light weight and a feature without comparison in this focal length range: image stabilization. If your kit is missing an ultra-wide focal length lens, it is very likely that you would find this lens worth adding.
B&H has the Canon EF-S 10-18mm f/4.5-5.6 IS STM Lens in stock.
