Most jobs I will take both cameras - the RX1R and the A7R with the Zeiss 55mm f1.8 lens. For onsite cafe, restaurants & markets shoots, I can easily get away with only the RX1R, truly amazing camera. Add the Sirui carbon fibre tripod, lots of memory cards, spare batteries and my 13" Apple Macbook Air, I am ready to go.
The Fotodiox grip is a must for me for fppis.com as the work is mainly onsite, in confined spaces and mostly 'handheld'. The Sony Electronic Viewfinder is stunning for framing and seeing the shot as it is and the LHP1 lens hood is great for protecting the lens in the tight spaces I shoot in.
The A7R is ideal for my work and travel. It is compact, light, full frame, high IQ, great in low light and the controls are well designed. Together with the RX1R, I have the near perfect pair.
