Tokina AT-X PRO 28mm
Score: 85/100
OM System M.Zuiko Digital ED 12-100mm
Score: 84/100Rankings
The Tokina AT-X 16-28mm f/2.8 PRO FX provides a constant f/2.8 aperture with high optical performance and full weather sealing for Nikon full-frame shooters. Its heavy weight and absence of a filter thread make it less convenient for travel. Best suited for professional landscape and architecture work.
The Olympus 12-100mm f/4 IS PRO is a professional-grade, weather-sealed zoom offering razor-sharp optics and industry-leading 7-stop image stabilization. Its trade-offs are a slower constant f/4 aperture, some distortion at extremes, and a heavier package. It excels for hybrid shooters and travelers needing a versatile, rugged all-in-one lens.
