In my honest opinion after looking at all the past and present options of Micro Four Thirds camera I still find my Panasonic G2 and, my wish camera, GH2. The reason I bought into this system was not the light weight possibilities, not the diminutive size but the excellent ergonomics and the plethora of buttons and controls. Compare to Canon EOS 550D, Nikon D5100, Sony A450 and Pentax K-r witch where my option at the time I bought my Panasonic neither had so many controls that where, some, essential to me. The most buttons, dials, switches that I use are most at the top, least at the bottom: * ISO (obviously) * Metering (very often) * Drive Mode * AF Mode * AF Select * AF/AE Lock * White Balance The one thing that very few people talk about is the excellent exposure dial because so many entry level and even enthusiast DSLR and MILC camera have one dial that makes a bit cumbersome to use where Panasonic G1/GH1/G2/GH2 (I really don't know what other models uses them) has a clickable dial that should and is equivalent to 2 dials and it's even easier to just us one finger to change 2 types of exposure (Aperture, Shutter Speed, EV) and the additional zoom in manual focus/manual lenses by engaging. Although it's not as good as having two of them but is hell a lot better then one. And since 3 out of 4 lenses that I own are manual legacy lenses (50mm f 1.8, 135mm f 2.8, 70-210mm f 4-5.6 all M42 mount) it's really awesome that I can change aperture on the lens and and EV in A/S Mode and the shutter speed in M Mode and clickable zoom with magnification at a turn of the dial. Seriously I just love using my camera because of its no-meniu all buttons/dials control and ergonomics that may be keeping me from upgrading. Canon EOS 550D Canon EOS 650D Nikon D5100 Nikon D5200 Olympus OM-D E-M5 Panasonic Lumix DMC-G2 Panasonic Lumix DMC-G5 Panasonic Lumix DMC-GH3 Pentax K-r Pentax K-30 Sony Alpha A450 Sony Alpha A57 I know it's a mood point, a very personal preference but from all the options above Panasonic G2 and Olympus OM-D E-M5 has the most controls available to you. I always loved the Canon lenses option but not there cameras, I like Nikon's cameras but not so much the lenses, I love Pentax cameras and lenses but something really wrong with there QC and prices, I never liked Sony's cameras because the have so much empty space on them and button for most if not useless options but they do have a very good selection of lenses. All in all my dream camera is the infamous Olympus OM-D E-M5 but I think I'm going to skip this generation for lack of money and curiosity of what are Panasonic's next toys. And I'm really disappointed in Panasonic GH3 because of it's ergonomics, I do like that it's a bit bigger but they could have kept, at least most of, the previous layout of the buttons and dials because they where very very good, maybe moved the ISO button on top, a small dial for metering where is now the AF mode ? Well anyways what is your opinion of the controls and ergonomics on your camera, how do they compare to others, maybe the reason you chosen that camera and not another (from the ergonomics and controls layout and options) and what would you like to see in the future on your or other's DSLR/MILC.
