Deciding between a new Canon EF 50mm f/1.8 STM and a pre-owned 50mm 1.8? We compare price, features, and value to help you choose the right budget prime lens.
Quick answer
If you want the latest features and a warranty, choose the new Canon EF 50mm f/1.8 STM. If you're on a tight budget and don't mind pre-owned gear, the used Canon 50mm 1.8 offers the same classic look for less.
Price difference and what it buys you
The most obvious difference is price. The new Canon EF 50mm f/1.8 STM is priced at $1,627.26, while the pre-owned Canon 50mm 1.8 comes in at $1,199.25. That's a saving of over $400 if you choose the used option.
What does that extra money get you? The new STM version adds a metal mount and instant manual-focus override, plus closer focusing. These are practical upgrades if you shoot video or frequently switch between autofocus and manual focus.
The pre-owned lens is essentially the same optical design, so image quality is nearly identical. The trade-off is that you miss out on the newer build and features, and you should check the condition of a used lens carefully.
Build and handling: metal mount vs plastic
The Canon EF 50mm f/1.8 STM has a metal mount, which feels more durable and is less likely to wear over time. The older 50mm 1.8 II has a plastic mount, which is lighter but can be more fragile.
If you plan to keep the lens for years and use it heavily, the metal mount is a good investment. For occasional use or as a backup lens, the plastic mount is usually fine.
The STM also adds instant manual-focus override, so you can fine-tune focus without switching modes. This is a small but handy feature for portraits and macro shots.
Autofocus performance and video use
The STM motor in the newer lens is designed for smooth, quiet autofocus, which is a big plus for video recording. The older lens uses a micromotor that is noisier and less smooth.
If you shoot video on a Canon DSLR, the STM lens will give you much better results. For stills, both lenses focus quickly enough for most situations.
The closer focusing of the STM lens also lets you get nearer to your subject, which is useful for food photography or small product shots.
Trade-offs at a glance
- Price: The new STM costs $1,627.26, while the pre-owned version is $1,199.25. You save over $400 by buying used. If budget is your main concern, the used lens is the clear winner.
