Northlight has posted their initial review of the new Canon EF-S 10-18 f/4.5.5-6 IS STM lens. As you would expect the lens appears to be a very good deal at $299, although it's not going to set any benchmarks for optical performance. It is however, a great completement to your APS-C stills or video kit if you don't need ultra wide angle very often. If you do, there are better and more expensive options out there.
“If you're not used to ‘shooting wide' then this lens is a very welcome addition to Canon's line-up. At appreciably less cost than the EF-S10-22, the 10-18mm surprised me with its build quality and optical performance. The image stabilisation adds to its general purpose usefulness and partly makes up for its relatively restricted aperture.”
