Sigma

Sigma, as always, is showing its broad lens range but this year augmented with a 'near-production' version of its DP2 large-sensor compact.

There are also new lenses on show, incorporating the company's OS optical stabilization system. The OS system is compatible with the image stabilized bodies from Pentax and Sony (with the choice of which system should be used for different situations). These include the new 18-50 F2.8-4.5 OS HSM, an intermediate-level stabilized upgrade over the kit lens bundled with many DSLRs. There's also a 50-200MM F4-5.6 OS HSM that offers an alternative to the second lens offered in many manufacturers' lens kits. Both lenses have a micro-motor type HSM that doesn't allow manual focus override while the new 10-20mm constant F3.5 HSM offers a ring-type focus motor that does offer the feature.
