So I've been doing a bit of research... and I would love to get a Canon 430exII, but I can't find a good deal on one right now and they're kind of expensive (especially since our Canadian dollar is so weak right now).
But I found a good deal on a Canon 50mm f/1.8 II for $90 Canadian. So I think I'll get that next. I have a birthday coming up so I'll ask my parents for that one. The f/1.8 should help a lot in lower light situations so I might be able to avoid using my stock flash.
I think that even if I eventually buy a more expensive lens, the 50mm f/1.8 II might still be useful because it's so small and light.
I was also thinking of getting a new camera strap because the one that came with my camera is pretty short.
I know that a flash is necessary for good indoor portraits, but I don't really like using a flash just because I think they're annoying... so even if I did buy a nice flash, I'm not sure I would use it too often. But that "nifty fifty" seems like a useful bit of kit to get and I guess it will take much nicer pictures than my stock lens.
Also, would it be an improvement to get something like a Gary Fong Puffer Pop-Up Flash Diffuser. It's only $13... so would that be an improvement over the stock flash?
