There is a new lens kid on the block: The Samyang 3.5/24mm TS  – a tilt-shift lens. I settled for this piece of glass because I didn’t want to spend close to 1800 Euros for the the Canon eqivalent plus the 400 for the Metabones adapter to put it on my Sony A7 bodies. Is it inferior compared to the Canon lens – certainly! But see for yourself -stopped down to f 8 on the Sony A7r – no sharpening applied in Lightroom. Certainly good enough for the enthusiast who doesn’t have to make a living out of architectural photography…saving more than 1000 bucks compared to the Canon rig and no adapter needed….
