Although the lens is designed for asp-c with a small image circle, zoom lenses will cover the ff sensor at some point as you zoom towards the long end. The image circle expands creating a larger image on the sensor, loke a tele-converter. My Pentax DA 16-45 zoom covers the FF at 20-45mm. The Sony 10-18 zoom covers FF from 11-18mm. See you may just get lucky. You need the fancy adapter for EF lenses because they don't have an aperture ring. You can also force the A7 to FF with a crop lens. In the menu under the gear, select # 5, item 2. On off or auto. Aps-c capture size.

Sony A7 Pentax K5ii Canon 5D

Thank you for your in depth answer. Can you recommend and 18200 full frame lens that can work on an EF adapter? The Sony range won't hit the market till end of 2015.

Thanx William
