Well I guess its just where my expectations are with the camera for the most part in the IQ department. The other aspects I'm extremely happy with.
I love the cameras small package, I love the lenses, I love how small the lenses are, I love the usability, I love the handling, I love how it makes you think about the picture before you take it instead of taking 20 pictures of the same subject, I still find it unique and interesting focusing with the RF system. Obviously it is really the only "mature mirrorless" system on the market.
What I'm not a big fan of is the promotion of how people compare the sensor to today's technology. The persona with the comments of "They [images] had a level of detail I haven’t seen before." I do not like. Sure the M8 can produce great images, a different look, with unique features not doubting that. It just doesn't appear to hold the technical capabilities of new technology. Based off what I have seen over the past 6 months of using the camera, the sensor doesn't hold its own as well as everyone claims compared to new tech. Rightfully so as it is almost 7 years old so I can't hold it against the camera.
I feel I am a technologist and I guess it is partly my fault for thinking my "attitude" of a picture could overcome the massive technology advancements between these types of cameras. I am looking at it from a perspective of this; if I carry one camera and I put my eye up to the viewfinder and hit the shutter button, which image am I going to want to work with? The 5d3 or the M8? If I'm out shooting for fun it doesn't matter, but if I'm out shooting with a purpose I can't justify using the M8.
I hate to leave the ecosystem as I love everything surrounding it with the history and the support for the M mount system but these things seem to big to overcome and it causes me not to pick up the camera. Maybe with the M9 I wouldn't have thought any of this and I wish I knew someone close that had one that I could try out but I don't. I'm still playing with what I want to do and I'll be thinking about it and considering what I want to do in the next week or so.
