This may seem like an odd question on the M4/3 forum, but I could use some thoughts and advice. I've been pining after the 17mm 1.8 since I got my OMD, however, I'm still using my 50D, and I've also been wanting to get the Canon 28mm 1.8. Since I can only afford one, I guess I'm looking for some thoughts to sway my decision one way or the other. I love the fact that both can be used for landscape and/or everyday street use and nice indoor low light shots. Any and all advice is appreciated.
