Call them EVILs (Electronic Viewfinder Interchangeable Lens), CSCs (compact system cameras) or MILKs (mirrorless interchangeable lens cameras), but these cameras all have a few things in common.  They’re small, and they’re meant to replace your big camera to a certain extent.  Yes some people are stepping up to these cameras from a P&S, but for the most part anyone reading this will be someone with a DSLR that’s looking to downsize for one reason or another.  All of these cameras offer “large” sensors and all but the fuji offer interchangeable lenses.  The reason most people want to get into a camera or system like this is because they offer most of the image quality of the larger DSLRs in a MUCH smaller package. Personally I’ve been shooting a PAD since 1/1/2008.  I’ve been posting them here on the site at first as dedicated PAD shots (photo a day), then as weekly updates, and more recently much more spaced out updates, but I’m still shooting my family daily.  Because of this I’ve learned to love a smaller camera option.  When I started this project I had a 5D with a 24mm 1.4 as my go to setup.  Great IQ but not a small package (but smaller than the 1Dii and 24-70 I came from).  Next came the GF1 with 20mm 1.8.  Loved the form factor and got hooked on EVILs with it, but it’s ISOs were limiting me inside with kids that don’t like flash…  Next came the NEX5 but it’s fastest small lens (which is unfortunately still true) was the 16mm 2.8 and even with it’s 3200 that wasn’t fast enough.  Then fuji announced the X100 and I was in love.  f/2, 3200, APS-C sensor and a dead sexy body with manual controls…. Until I got one and the AF (with the initial firmware) was terrible.  So bad in fact I only had it a month.  From there I went to the OMD which was amazing.  My only complaint with it was the size and or placement of the built in viewfinder.  I don’t use the optional viewfinders much (I don’t buy them if they’re an add on) and the OMD’s version makes it a rather tall camera for something meant to be small.  The buttons were also tiny but I learned to live with that.  But in the end I sold it and moved to the GX1 and have since also grabbed a EPM2 so I can try MFT with modern sensors but without the EVF…  For this review I’ve also borrowed a friends X100 (and updated it to 1.3) and another friends NEX5r with 24mm 1.8 Zeiss.  A big thank you to Preston Power and Matt Bailly for loaning me their cameras!!! So, how do they all stack up?  Let me just say up front there is not a bad camera in this test.  They’re all fantastic.  Yes, I know, I’m not really giving a great review initially by saying that, but they really all do produce wonderful results at this point.  BUT…  They all have their pros and cons so lets take a look at each system and see how they compare:
