Olympus Zuiko OPTM5020M43O 50mm
The Olympus Zuiko Digital 50mm f/2 Macro lens is highly praised for its exceptional sharpness, bright aperture, and solid build quality, making it a favorite for macro and portrait photography. Users note its compact size and splash-proof design, but many find the autofocus slow and prone to hunting, often treating it as a manual-focus lens. While it delivers stunning image quality with minimal chromatic aberration, its 1:2 magnification ratio and telephoto equivalence on 4/3 cameras limit its versatility for group shots or walk-around use.
Pros
- Exceptional sharpness
- Bright f/2 aperture
- Solid build quality
- Compact size
- Splash and dust proof
Cons
- Slow autofocus
- AF hunts frequently
- Not true 1:1 macro
- Lens hood blocks manual focus when reversed
- Telephoto equivalence limits group shots
