Sigma 18-35mm f1.8 DC HSM First Impression By The Phoblographer

The Phoblographer got their hands on Sigma’s recently announced UFO (Unbelievable F-stop Object), the amazing 18-35mm f1.8 DC HSM lens with a constant f/1.8 aperture over the whole zoom range. Moreover, the lens can be connected to Sigma’s USB dock to update firmware. The main points of The Phoblographer’s impression:

• very good build quality
• ease of use
• speedy and accurate focusing
• about image quality they write:
  • We weren’t allowed to put a card into the camera because this is a prototype lens, but the images that we saw weren’t so contrasty or punchy. It also seemed a bit soft wide open–and for that reason we’re going to blame that on it being a pre-production copy.
