This subject has been covered a bit in prior threads, but I don't think my specific question has been answered. I am very happy with my OMD system, which routinely produces excellent quality in print sizes up to 16x20. I find that it fills the niche that used to be occupied by my medium format rangefinder system during the film era. I would like, however, the ability to sometimes print larger. This would be mostly landscapes, taken on a tripod at base ISO; essentially, the niche formerly occupied by 4x5. The Sigma DP1 Merrill seems promising for this use. The 28mm equivalent lens is my favorite focal length, the image quality is reputed to be incredible, and the handling and other shortcomings of the camera aren't very relevant in my planned application. My question is how much larger will I be able to print from the Merrill than from the OMD. I'd be interested in the views of anyone who has shot with and printed from both cameras. For example, how large can you print from the Merrill and get the same quality you would see from the OMD at 16x20? Thanks.
