Now this may sound subjective, but I completely understand Panasonic skipping the numbers from 2 to 6. I may not care much about the EVF (yet), but just on the outside, the tilting lcd, the double wheels and the AF/MF switch makes it another machine altogether! Another thing I did not notice being mentioned too much, but which I found extremely useful, is the WYSIWYG mode in manual - finally! On the GX1 I had to use the aperture/shutter preview, but now it can be enabled right away and kept on all the time (why just in M leaves me clueless). More - there's the option to raise ISO limit just by turning the front wheel when needed - very very handy. (BTW ISO 3200/6400 look much better!) I am finding the level of options that can be customized fantastic - as an example, I was not very happy in having the on-screen magnification in manual focus mode on at all times - now it can be turned off and assigned to one of the buttons. I use peaking, and if needed- click - here you have it! Same goes for the ability to recall and remove the histogram and the level assist. Oh, and the e-shutter is great! From the limited use so far, I can confirm the low light focusing having vastly improved over the GX1. I hope to post some pics and real-life experience next week if the weather decides to calm a bit for the weekend. Some negative notes to balance a bit the post - I liked more the flash on its previous position - it's much harder to tilt now that's in the middle of the body. Another migration that leaves some question marks is the lens mount - now the body feels unbalanced to the left with the 12-35, and unless I find a way to work around it, goodbye one-handed shots, and fast lens changes. Those are my 2c for now, hope someone may find them helpful.
