Hi, Could anyone recommend a really wide angle (and sharp from corner to corner) lens that will work with the GF1? I am looking for something wider than the 14-45mm but not fisheye shaped. Maybe there is a DSLR lens that might be physically larger than a micro four thirds lens but would be good quality and do the job with an adaptor? The Panasonic 7-14mm looks great but it's really expensive so I am hoping to find something like that in an adapted lens that's more affordable . . . . . any suggestions appreciated.
