Valid points, Rover. For myself, I wanted a 20mm on FF to get really wide close up ability and bought a Voigtlander 20mm f3.5 partly for that. Regrettably, the Voigtlander is totally not suited for that (due to heavy astigmatism close up). If the 20/24mm Tamrons would have existed for EF mount, I would have bought one of those instead.
