Sure, but all-plastic entry level SLRs are usually matched with lightweight AF lenses. I find such a combination one of the least damage prone, and I use them a lot because I'm too lazy/sensible to carry my professional cameras unless there's a very good reason. They function more like point and shoot cameras with a mirror box, than 'serious' cameras, something I'm grateful for.
