I currently have two cameras - Sony A77 and an RX100. I bought the RX100 as a travel/street shooter but really haven't used it as much as I thought - it is currently advertised for sale. I am tempted to sell the A77 and my selection of lenses, and buy an XPro1 and associated lenses and equipment. I have a neck injury so weight is a bit of an issue, so something smaller and lighter would be good. I have tried a Panny GF3 before with the 20mm f/1.7 - loved the lens, didn't love the lack of a viewfinder, which is probably the reason I didn't gel with the RX100. Does anyone have any experience with the XPro1? I have tried one briefly in a camera shop - but it wasn't enough of a test to make my mind up. I also tried the OMD which seemed pretty good, and have been looking at the reviews of the Panny GX7. Any thoughts?
