It's small, inexpensive, sharp, and focuses almost right up to the front element. I have almost no complaints about the EF-M 28mm f/3.5 Macro IS STM. It's a nonissue at narrower settings when shooting JPGs. An f/3.5 JPG shows -1.2EV illumination at the corners, which is just outside our -1EV tolerance. If you shoot JPGs, your camera automatically brightens corners to make them closer to the center. For indoor and low-light shooting, the EF-M 22mm f/2 STM is a stronger option. The small size is helped by a rather narrow maximum aperture, f/3.5, which makes the lens a bit less versatile as an all-around prime. You'll need to twist the barrel while holding the unlock switch in order to telescope the center out a bit, adding about a half-inch of height. It's a collapsible lens, which means those measurements are logged at its smallest position. The EF-M 28mm measures 1.8 by 2.4 inches (HD) and weighs just 4.6 ounces. If you've got a Canon mirrorless camera, this is a lens to get, and easy to call an Editors' Choice. Images are crisp from edge to edge, and macro shooters will love its high-magnification design and integrated LED light. The Canon EF-M 28mm f/3.5 Macro IS STM ($299.99) is delightfully tiny, matching well with EOS M bodies. But lenses aren't always small, with some systems featuring glass that's quite large compared with the body. Mirrorless cameras are popular for photographers who want the image quality of an SLR without the bulk.
