The first difference is that you need lenses that can project a larger "image circle" to cover the larger sensor. A lens for a 35mm full frame camera needs to project about a 43mm diameter image to cover the whole frame. But a 40x54mm sensor needs a roughly 68mm diameter image. As you might imagine, making lenses with larger image circles introduces new tradeoffs. And we might want an even larger image circle than the sensor requires to allow the use of perspective correcting shift movements.
