Canon 50mm f/2.5 Compact Macro EF-Mount Lens {52}

Canon's 50mm f/2.5 macro: half-life-size reach, pocketable build.

The Canon EF 50mm f/2.5 Compact Macro has been in the EF lineup since 1987, and its longevity is earned. At 280 grams and 63mm long, it rides on any EOS body without upsetting the balance, and the metal barrel and mount hold up to the kind of daily handling that wears out plastic-bodied lenses. The 52mm filter thread keeps step-up ring costs low if you're already working with Canon's older glass.

The lens closes to 0.23 meters for 0.5x magnification, which covers most close-up work: product details, small flora, insects at rest, coins, jewelry. For true 1:1 you'd need the optional Life-Size Converter EF, but half-scale is enough for most shooting situations. Autofocus is handled by an internal micromotor, and both a distance scale and depth-of-field scale are engraved on the barrel, genuinely useful when you're working at close focus and need to know exactly how much depth you're holding at f/16 or f/32.

At f/2.5, it earns its place as a normal prime when the macro subjects have cleared the frame. That's two lenses in one body slot, which matters when you're traveling light or working out of a small bag.

Who It's For

Food photographers shooting tabletop work on a budget will find the 0.5x magnification and close 9-inch minimum focus distance give them enough detail for most editorial needs without the bulk of a dedicated 100mm macro. Travel photographers benefit from the 280-gram weight and compact 63mm length when every gram counts. Film shooters still running EOS film bodies get a native-mount macro that requires no adapter. Mirrorless photographers on Sony E, Nikon Z, Fuji X, Canon RF, or L-Mount systems can run this lens via adapter as an affordable close-up option with a proven optical formula.

FAQ

What's the closest you can focus with this lens?

0.23 meters (9.06 inches) for 0.5x magnification. That's half life-size, which handles product shots, insects, small flora, and jewelry without needing the optional Life-Size Converter.

Does this lens have autofocus?

Yes. It uses an internal micromotor for AF, which is standard for EF-mount macro glass of this era. Manual focus override is available by turning the focus ring, but there's no full-time manual mode.

Can I use this on both full-frame and crop Canon bodies?

Yes. It's Canon EF mount, so it works on any EOS camera-full-frame or APS-C. On crop bodies, the effective focal length becomes roughly 80mm equivalent, which actually improves working distance at macro magnifications.

What's the depth of field like at macro distances?

Shallow. At f/2.5 and 0.23m, you're working with millimeters of focus depth. The engraved DOF scale on the barrel tells you exactly how much you're holding at f/16 or f/32, which is critical when every millimeter matters.

Is this lens weather-sealed?

No. The metal barrel and mount are durable for daily handling, but there's no weather sealing, so keep it dry in the field.

How does this work as a normal 50mm prime?

At f/2.5, it's a competent standard prime for general shooting. The real value is carrying one lens that does both normal and macro work-two lenses in one barrel if your subjects vary between wide shots and close detail.

What accessories are available for this lens?

Canon offers a hard case (LHP-C10) and soft case (ES-C9/LP814). The 52mm filter thread is standard, so step-up rings are cheap if you're already using older Canon glass.
