About dustproof, water resistance, and simplified weather resistance

Dust-proof and water-resistant lenses

DA 55mm f/1.4 SDM, DA 300mm f/4ED [IF] SDM, DA 200mm f/2.8ED [IF] SDM, DA 16-50mm f/2.8ED AL [IF] SDM, DA 50-135mm f/2.8ED [IF] SDM, DA 60-250mm

f/4ED [IF]SDM

These DA lenses are dust-proof and water-resistant because each part is individually sealed. This makes it difficult for dust and water to enter the lens.

Lenses with simplified weather-resistant construction

DA 18-55mm f/3.5-5.6 AL WR, DA 50-200mm f/4-5.6ED WR

These lenses are made with a simplified weather-resistant construction by using DA lens sealing technology which makes it difficult for water to enter the lens.
