Early curiosities and findings:
– New 16-35mm GM lens has a new fly by wire focus ring mechanism. Optimized for manual focusing!
– 12-24mm is surprisingly resistant to flare (unusual for such a wide angle zoom)
– 12-24mm lens weights half compared to the Sigma 12-24mm and Canon 11-24mm lens competition
