Tokina ATX-i 100mm
Score: 82/100
Sigma 18-50mm F2.8
Score: 82/100Rankings

The Tokina ATX-i 100mm f/2.8 macro delivers true 1:1 reproduction, a fast aperture and a 55 mm filter thread in a compact package. It lacks an internal focus motor, causing autofocus limitations on some Nikon bodies. Perfect for macro photographers needing high sharpness and decent working distance.

The Sigma 18-50mm F2.8 DC DN Contemporary is a compact, constant-aperture standard zoom for APS-C mirrorless cameras, offering sharp optics and close-focus capability. Its lack of image stabilization and reduced corner performance on very high-resolution sensors are notable trade-offs. Ideal for travel and street photographers who value portability.
