Tokina lenses from Japan are a budget photographer's great friend. If you own a Sony E mount, Sony A mount, a Canon or Nikon camera but don’t want to splurge on a dedicated lens, you can trust Tokina lenses to offer comparable performance at a slashed price. The reason Tokina is able to offer lower-priced lenses (along with superior build quality) is because of the more affordable SLD glass they use. This special low-dispersion glass has low chromatic aberration and lets the lens stay always in focus. You can take your Tokina camera adventuring and test out its solid build quality at the click of a button with Diamond Cameras.
