Of all the luck...no sooner had I decided to stop messing around with too many Micro 4/3 cameras and pare my m4/3 kit down to my two favourite bodies (E-M5 and GH1), I get a dreaded memory card error message on my GH1 and a card that refuses to be ejected out the camera. The initial guesstimate to fix the camera (my preferred option) apparently might involve fitting a new main circuitboard which could be more expensive than finding another second-hand GH1 body. Of course my other option is to look at another m4/3 camera entirely but I have my doubts about replacing the GH1 with another model. Firstly, I'd want it to be a flip-screen Panasonic which limits my choices to the GH2, G3, and G5. Part of the reason that I like the GH1 so much is because of the dynamic range of the sensor, which rules out the G3 as an option. I do also quite like the multi-aspect sensor which shuffles the G5 to the bottom of the list. So that leaves just the GH2... I'm fairly certain that GH2 has improved performance at high ISOs and doesn't suffer from the same banding that GH1 can at ISO 1600+, but I'm not really looking at low light performance since I have the E-M5 to cover that. With more megapixels the GH2 offers a bit more resolution than the GH1, but other than that I'm unconvinced that the GH2 offers at step-up in lower ISO (200-800) performance, and the bare sensor numbers from each camera even indicate that the GH2 may be in fact be a tiny step backwards. My feeling at the moment is that I should stick with the GH1 because I've gotten to the point where I am very happy with the way that I can process the GH1 raw files to my liking, and that it gives an output that is unique compared to my other cameras. The question mark that I have is that if the GH2 sensor has a similar philosophy to the GH1 and produces similar IQ than maybe it is worth taking this opportunity to switch to a newer camera. BTW, video is not an issue for me. Has anyone else switched from a GH1 to a GH2, and how did you find the move?
