Recently picked up a T4i with standard 18-55mm IS STM kit lens for a steal. Now I'm looking to expand my lenses to include a wide angle and zoom lens. I'll probably be using this camera for 70% photos 30% video. I've also just gotten into photography, so I really don't know what to look for. I do a lot of backcountry skiing so big landscape photos/sick pow shots are what I'm hoping to be taking on the photo side, while for video I'll probably be shooting some urban/park footage plus the odd line out in the BC. In the summer Ive gotten pretty big into climbing so I figured a zoom lens would be best suited for that. For a wide-angle lens I've done some research and narrowed it down between the Canon 10-18 4.5-5.6 IS STM or the Tokina 11-16 2.8. Now from what I understand, the canon will be better for video because of the STM, but the tokina will be much better for night and action shots because of its f2.8. The tokina also seems pretty popular here on NS. I currently found some local ads for the Tokina for $400cad with a filter or the canon for $350cad with a filter and hood. As for zoom lens I really have no idea what I'm looking at and everything with small f/stops seem to be pretty pricey. I saw the canon 55-250 IS STM is pretty cheap but I also feel like its a cheap lens. My girlfriend's sister has an old 75-300 IS that I could maybe pick up for cheap as well. Would you guys recommend it anyways for someone just getting into photography? Finally, is there any other recommendations you guys have! Thanks
