I haven't used the G1X much I must admit. I planned on using it as my go anywhere camera but it's proving to be a little too big for that. I then went for the Panasonic GM1 which proved to be a perect size. I have two main problems with the GM1; the lack of a viewfinder which meand I have to put my glasses on to see what I'm framing on the viewfinder. My eyes aren't what they used to be . Secondly, and this was the killer point for me, that damn small wheel on the back. I use EC a lot and using that little wheel is just impossible. Everytime I want to adjust it some other function comes up because the pressure pad is just too soft.
Later I'll post some images that I managed to make with the GM1 using the minute 12-32 lens. Don't get me wrong, I'm impressed with what this camera can produce because it has the same sensor as in the GX7 and there's nothing wrong with the images I get from that camera. I've decided that I just can't get used to using the GM1 and since Panasonic have just announced the GM5 which, for me, solves both problems I have with the GM1 I'm going to upgrade to the GM5. I just need a viewfinder and the GM1 will be the last camera I purchase without an EVF.
I believe I digressed a little there because this post is actually about the Canon G1X (original version). The images I get are actually very good indeed. The sensor is first class and colours and contrast are top. Shame about the mini OVF which doesn't always work for me. Because of the OVF problem I looked hard at the second version Canon has brought onto the market but they've changed some things that I'm not really too happy about. Firstly they've taken the EC wheel away and put it on one of the buttons on the back of the camera. Secondly, they've put a dmn wheel on the back to change the EC value. This is why I'm going away from the Panasonic GM1. The Mark II is therefore not an option but I will hang on to the original G1X because of image quality.
