With the launch of the GX8 and the recent and planned lens releases From both Oly and Panasonic, I've been reflecting on where the format is heading. a) We're seeing lots of high-end lenses - 42/1.2 Nocticron, 12-40 Pro, 40-150 Pro, 7-14 Pro, 100-400, 300 Pro etc. In all cases, the size and weight has gone up dramatically and in many cases they are approaching APSC and even FF equivalents. b) The E-M1, GH4 and now the GX8 are all pretty big cameras. The GX8 in particular is a bit of a surprise. These two trends point towards a move up-market; an aspiration for best IQ rather than where u43 started - a size/IQ trade off. This is confusing me since no matter how big you make the lenses and cameras, the sensor size isn't going to change; and sensor size of course is a big determinant of the final IQ. So, we need the sensor IQ to improve too. This brings me to the last observation: c) The new sensor in the GX8 has gone for more Mp over improved noise and DR. Based on early reviews and sample images, the noise is no better than the current 16Mp sensors. This seems absolutely crazy to me since if there's one area where u43 IQ suffers compared to its current competitors it's noise, not resolution. I've never, ever thought "I need more Mp", but I've very often found, even at base ISO, that noise creeps in when doing PP (e.g. shadow fill, sharpening, clarity etc). Doing any serious PP to images at ISO 1600 or 3200 is not a serious proposition. This is the first real sensor upgrade in over 3 years and I'm just amazed that we're not getting BSI or such like to improve noise. So, where is u43 heading? It seems it's losing its roots as a small size/great IQ compromise system - but going big isn't likely to convince anyone that the IQ is up to a Sony A7. Personally, I'd just like to see cameras at the E-M5 size with an upgraded sensor that delivers lower lower noise (plus improved CAF of course!).
