Quick answer
Yes, the Canon EF 50mm f/1.8 STM is a fantastic portrait lens for Canon DSLR users, offering a bright aperture for beautiful background blur and sharp, natural-looking images at an affordable price.
Why the 50mm focal length works for portraits
On a full-frame DSLR, 50mm gives a natural perspective similar to human vision, making it ideal for head-and-shoulders and half-body portraits. On APS-C cameras, it becomes roughly an 80mm equivalent, which is even more flattering for tight portraits.
Trade-offs to consider
The f/1.8 aperture is bright but not as fast as f/1.4 lenses, which gather more light and offer even shallower depth of field. The plastic build feels less durable than metal-barreled lenses, and the focus ring is small and not ideal for manual focus. Also, there's no image stabilization, so you'll need a steady hand or a tripod in low light.
Frequently asked questions
- Can I use this lens on a crop-sensor Canon DSLR?
- Yes, it works perfectly on all Canon EF-mount DSLRs, including APS-C models like the Rebel and 90D. The effective focal length becomes about 80mm, which is great for portraits.
- How does the STM autofocus compare to older versions?
- The STM (Stepping Motor) provides smooth and quiet autofocus, especially beneficial for video. It's faster and more accurate than the older DC motor in the f/1.8 II version.
- Is this lens good for low-light photography?
- Yes, the f/1.8 aperture is about 1.3 stops brighter than a typical zoom lens at f/2.8, making it a solid choice for indoor or evening portraits without a flash. For very dim conditions, consider a tripod or a faster f/1.4 lens.
- What is the build quality like?
- The lens is mostly plastic with a metal mount, keeping it lightweight and portable. It's not weather-sealed and feels less rugged than L-series lenses, but it's durable enough for everyday use.
