Few lenses in this guide will still fit a camera you buy five years from now; this one already fits the camera you bought ten years ago. The EF mount goes straight onto EF and EF-S DSLRs, from a Rebel to a 5D Mark IV, and on an R-series body it works through Canon's mount adapter, which is the only extra you need. Buying into a lens mount is the real commitment in this hobby, and this is the least expensive way to keep your options open.
Fifty millimeters on full frame is roughly the view of your own eyes, which is why the framing feels right before you know anything about composition. On a crop body it behaves like an 80mm and becomes a proper portrait prime. Wide open at f/1.8 the background falls away and the frame stays bright enough that the flash stays in the bag. Dim living rooms, birthday candles, a restaurant table at night: this is the lens we reach for.
At 5.6 ounces it lives in the bag without a decision, and the close focus is the surprise nobody mentions. It gets to 1.15 feet with 0.21x magnification, which is enough to fill the frame with a plate of food or a flower. That is a specification most shoppers never read on a 50mm, and it is the one that makes the lens useful on a table.
What it will not do is zoom. In a tight room you back into a wall, and from the back of a school auditorium you crop. That is the boundary of a 50mm rather than a flaw in this one. For evenings, portraits, and the first step up from a kit zoom, it turns an entry-level body into a camera that works after dark.
Pros
- Mounts natively on EF and EF-S DSLRs
- f/1.8 keeps dim rooms and evening portraits workable
- 5.6 ounces, so it rides along unnoticed
- Focuses to 1.15 feet for detail shots
Cons
- Manual focus is motor-driven and noisy
The lens we tell every Canon owner to buy first: it mounts on nearly any DSLR without help, works on R bodies with an adapter, and makes f/1.8 pictures that look far more expensive than they are.
