Just bought an Olympus 9-18mm f/4 from the Cameta deal via eBay (save $10 for Canadians). I sold my 12-50 this evening and decided I need a wide-angle. This lens sold me on its compactness and f/4 @ 9mm and that it can take filters, already have a variable ND @ 52mm. I'll likely only use it in good light so I'm happy with f/4. If I had a tripod with me I can open shutter for a bit indoors. Looking forward to the Olympus 60mm or the 35-100mm.
