Sigma

Sigma demonstrated their commitment to the growing digital SLR market with a brace of new lenses making their public debut at Photokina. This was also the first time we'd actually got our hands on Sigma lenses with a 4/3 mount. New lenses include the 18-125mm F3.5-5.6 DC (digital only), APO Macro 150mm F2.8 EX DG HSM, 24-70mm F2.8 EX DG and an all-new 28-70mm F2.8 EX DG, which is expected to sell for under £300 (US pricing to be confirmed). Last but not least is a very nice new AF dedicated Ring Flash, the EM-140DG.
