It looks like the Sony 70-400mm f/4-5.6 G SSM may have slipped out a bit early. The PDF manual for this new 105-600mm equivalent has surfaced on the web. Notable in the specs is that the zoom is a twist rather than a push-pull zoom seen on similar super-telephoto zoom lenses like the Canon EF 100-400mm L.
This could be a killer telephoto zoom when matched with the Super SteadyShot IS on Sony Alpha DSLRs. Check out the full specs below and stay tuned to Photography Bay for the latest on digital cameras and lenses as we approach Photokina 2008.
