Get the Canon MP-E 65mmDo not be cruel with novice users in canonRumors.
Therefore, we asked the novice users to kindly inform what type of photos do (or want to), and which camera has.
Ah sorry about that, thought the op was kinda joking given the lack of info. Now we know a little more about your needs though, I'd second the 10-18 stm, it's cheap, has good optics and will open up a whole new world with your landscape shots! It'll also be pretty useful for street shooting too but it's slow [aperture not very wide], so you may want a fast prime to back it up. I'd recommend 35mm and under since you already have the longer end covered with the 70 -300. Some people have recommend a 50 which could work, depending on your style. I, however found the focal length [80mm on crop] really awkward for street, I usually always ended up needing something wider and the times I needed reach, 80mm was not enough. It just kinda sat in the middle for filling neither need. Hope this helps.
