The lens we point a new EOS owner toward is almost always this one. Fifty millimeters is a comfortable place to learn: wide enough for a table of friends, long enough to flatter a face, and with an f/1.8 aperture that makes a dim living room shootable. At 5.6 ounces with a 49mm filter thread, it disappears into a bag and stays there.
What keeps us coming back is how much the aperture changes the photographs rather than the specification sheet. Backgrounds fall away at f/1.8, and the seven-blade diaphragm keeps the out-of-focus areas tidy instead of busy. The detail that surprises people is the close focus: 1.15 feet with 0.21x magnification, close enough to fill the frame with a plate of food or a flower without changing lenses.
Autofocus is the one place the price shows. The stepping motor is quiet and smooth, which is exactly why it works for video, and in good light it locks fast. In a dim room against a low-contrast subject it hunts, and it is not the lens for tracking a dog running at you.
It is one focal length, it isn't sealed against weather, and a wet shoot is not its day. What it does better than anything else here is teach: you move your feet to frame instead of zooming, and you learn what a stop of light is worth. On a crop body it frames like an 80mm, which is a fine starting point for portraits.
Pros
- f/1.8 aperture for low light and blurred backgrounds
- Light 5.6-ounce body that stays in the bag
- Quiet STM focus that suits video
- Closes to 1.15 feet for near-macro detail
Cons
- Hunts in dim, low-contrast light
- No weather sealing
This is the lens we tell every new EOS owner to buy first: a fast f/1.8 aperture in a body small enough to leave on the camera.
