Canon EF 75-300mm f/4-5.6 III
Score: 35/100
Panasonic LUMIX G Lens
Score: 60/100Rankings
The Panasonic LUMIX G 25mm f/1.7 ASPH is a compact, fast-aperture prime that delivers sharp images and quiet AF, making it a strong value for Micro Four Thirds shooters. Its lack of IS and weather sealing keep it from harsher environments, but its portability and price are hard to beat.
The Canon EF 75-300mm f/4-5.6 III USM is a budget-friendly telephoto zoom that offers a long reach in a lightweight plastic body. It delivers decent sharpness in the mid-range and quiet autofocus, but lacks stabilization and suffers from softness at the long end.
