Sony's tiny APS-C macro prime with 1:1 magnification and a 30mm focal length.
The Sony E 30mm f/3.5 Macro (SEL30M35) is a native APS-C E-mount macro lens providing 1:1 life-size reproduction at 0.095m minimum focus distance — the shortest MFD of any Sony APS-C E-mount lens. At 138g and 49mm filter thread it is the lightest Sony E-mount prime, enabling a compact macro kit. The 44mm full-frame equivalent perspective is close to normal for APS-C, making it workable for both macro subjects and general photography.
The optical design uses 7 elements in 6 groups. Seven aperture blades. The 49mm filter thread is a small, common consumer prime size. At 138g the lens is extremely light for a macro prime. Minimum focus distance of 0.095m achieves 1:1 magnification — full life-size reproduction. Maximum aperture of f/3.5. AF motor enables autofocus at macro distances. APS-C-only image circle — attaching to a full-frame FE body activates APS-C crop mode.
The 1:1 magnification at 0.095m enables full life-size reproduction of small subjects — coins, insects, small flowers — at the closest focus distance of any Sony E-mount lens. The 138g weight makes it the most practical macro prime for weight-sensitive APS-C kits. The 44mm equivalent perspective means it can function as a standard prime when not in macro mode, unlike longer macro lenses that are less versatile for general photography. The f/3.5 maximum aperture is adequate for macro distances.
On the used market the SEL30M35 is affordable as a compact APS-C macro prime. Condition checks: AF response at macro distances, front element for marks, and overall barrel condition. The Sony FE 90mm f/2.8 Macro G OSS provides 1:1 macro on full-frame with 90mm working distance for photographers who have transitioned to FE bodies. Compatible with all Sony APS-C E-mount bodies; activates crop mode on full-frame FE bodies.
