Okay, so after a lot of agonising about my equipment - after starting a new job I thought I'd finally sort out my digital gear to a proper standard - I think I've now settled. For now.
I was looking at m43 in general but my old GF2 and G2, while fine in the daylight, both have pretty poor high ISO performance. I was also missing a quality pocket camera - the film ones I have were generally better than the digitals, and their high ISO was okay _if I knew that I wanted to push beforehand_. T-Max 400 pushed two stops looks really great but you can't switch halfway through a roll. And carrying two pocket cameras for daylight and night time seems to defeat the point of pocket cameras.
I had been looking at the GX7 as an upgrade for a while but then splurged on the Ricoh GR as a birthday present. This was such a great camera that it changed my priorities. It's easily good enough to use as a main camera as long as you don't mind the fixed wide lens, and it's a stunning pocket camera too.
I used to put the Pana 14/2.5 onto the GF2 and use that as a wide body, backing up the G2 with a longer lens, when doing serious shoots, but now I have no reason to do that. In fact, I don't need another compact camera at all. A lot of the benefits of the GX7 are to do with its size but I have a quality compact now which is smaller than the GX7 would ever be.
So in the end I got myself a Lumjx G5 to replace the G2. It looks very similar and has an EVF, but it is very cheap nowadays due to being a year old (seriously wtf is up with the digital market - I got it for less than £300, when a year ago it was being called overpriced). Apart from the removal of a lot of the manual dials
it is a huge improvement over the G2 and has benefits over the GX7 - it has a proper grip, a big EVF and a _fully_ articulated screen i.e. can be pointed in any direction as well as fully closed to save battery. IQ at high ISO is decent and with the 20/1.7 prime I don't need to go past 1600 very often anyway.
I need a spare battery for it though. Mirrorless cameras eat power
So anyway that is my digital kit at the moment and unlikely to change much in the near future - a G5 with various lenses (14-42mm kit, 45-150mm, 20/1.7 and 14/2.5 primes, and convertors for manual lenses like the Helios 44M-4 which makes a great 116mm-equivalent portrait lens) and a GR as a wide angle and pocket camera. I'd take along the GF2 body in a side pocket as an emergency backup should the G5 fail.
