Hi. One might think that a G5 vs. EM5 comparison is a bit long in the tooth. Both cameras have been in the market for over a year and all has been said and done... that's partially true but not complete. I also don't think both cameras are obsolete yet (the EM5 is still part of the king of the hill group and the G5 is so cheap that I think it's a viable choice when considering the more-than-double-priced G6 which isn't that much better IMHO). I had an EM5 for over a year and sold it with the grip for a nice sum towards funding the upcoming EM1 (mainly for the bigger EVF and better controls). But as the EM5 had it's quirks (and I never really liked that spiky form factor) I realized I do not want to spend that kind of money on the EM1. As the Panasonic G5 was sold with the kit lens for 350$ I figured I'll buy one and if I'm unhappy I'll just sell it for little to no loss. Turns out there are quite a lot of differences between the EM5 and the G5 and I figured I might as well list them in a post for the benefit of prospective buyers. I'll try to make this concise (though it is comprehensive so it won't be short) and list the important stuff as I see them. Just to clear things: I shoot RAW and am a glasses wearer (relates to EVF comments). With the EM5 I used (not all at the same time) the following lenses: 14-45 (old 'kit zoom'), 12-35 F2.8, 14-42 PZ, 7.5mm roknion fisheye, 20mm F1.7, 25mm F1.4, 45mm F1.8. I thinned down my collection to my 3 favorites: 12-35 F2.8 (best all rounder), 7.5mm Fisheye (can amazingly be transformed to rectilinear if wanted using the adaptive wide angle tool in Photoshop) and 14-42 PZ when I want to be more portable. With the G5 I only used the above 3 (12-35,14-42 PZ, 7.5mm). Sensor: Better on the EM5, more DR to work with in LR, less noisy in higher ISOs and visually much more pleasing in very high ISOs (2000+).The G5 sensor is also quite OK (better than the GX1 I have as a backup camera). @ less than ISO 1000 the differences in IQ aren't that major. Take note - the EM5/G5 IQ gap seems much larger with OOC JPEGS but when shooting RAW it's smaller. IBIS vs. OIS: Not to start a fight about this but the EM5 5-axis is better than any OIS I used. I got 100% success in blur free images at 1/2 second exposures with lenses upto 45mm in focal length. With OIS I barely get such results upto 1/5 second exposures in a consistent manner. As I was trolled about this in another thread I will not waste my time trying to support this claim. Anyway - a person can fabricate tripod mounted images at a given shutter speed as 'proof' so I'm not participating in such debates. What I wrote is based on my experience and I gladly share it with others but will not go overboard protecting the validity of my words. I cannot control people who choose do disbelieve what I write here but am really stating the truth here. EVF/LCD QUALITY: The EM5 has smoother fluidity (especially in dimly lit room etc.) and I can see the whole image in the EVF. With the G5 I cannot see the whole scene; the left and right edges are slightly hidden. The quality of the LCD is good on both units. The EM5 only tilts while the G5 is fully articulate - this is really a matter of preference (I have to have the screen sideways on the G5 when I want to only tilt it; some might not like this) but the G5 winds hands down for possibilities here (esp. in video taking). EVF/LCD in ACTUAL USE: Both cameras differ greatly in the integration between the EVF and the LCD. On the G5 you can switch from EVF to LCD and whatever was shown on the one screen is shown (with a very short lag) on the other. On the EM5 this works slightly differently; the lag is more noticeable and if you are already looking through the EVF in record mode and want to go to playback mode you have to press the 'play' triangle and THEN the EVF button (it defaults to show the image on the LCD). On top of this you also have to disable the EVF/LCD sensor to even make viewing the playback images on the EVF. VERY ANNOYING! Ergonomics: The EM5 is horribly uncomfortable without buying an extra grip attachment even when using small lenses (like the 14-42 PZ) - I bought the HLD6 and used only the vertical part. The EM5 is noticeably taller (and heavier) with the grip as well (even the vertical part adds more than 100 grams and 1 cm to camera height). With the grip the EM5 has enough place for 2-3 fingers but still feels forward-heavy and there's an indentation in the HLD6 vertical grip which digs into the index finger if you have a heavy lens attached. In the very limited times I've used the horizontal part of the HLD6 I noticed that the palm of my hand inadvertently caused the FN buttons on the grip attachment to be pressed and had to disable them. The G5 grip is much more comfortable for me without any added attachments. There's also the issue of the strap lugs; in the G5 they're relatively flush to the body and on the EM5 they're of the D-ring variety which might dig into your finger when holding the camera (less of an issue when using the HLD6). Menus and Buttons: I had the EM5 for over a year and the G5 for just a couple of weeks and from the very start I felt the G5 is much better both in button layout and in the menu system. I prefer the custom quick menu on the G5 to the SCP on the EM5. The EM5 has 2 wheels but they're not comfortable to use (when using the grip you tend to use the front wheel in an awkward position. This is hard to explain why but it just is) I prefer the single wheel + rocker dial on the G5 solution (and it also zooms the PZ lenses is wanted allowing one-handed control on the camera with zooming!). Another small but annoying quirk relates to when you magnify and image in playback mode and want to jump straight back to fit-screen; with the G5 you press the middle button in the D-Pad whereas the EM5 has no way to achieve this in a click of a button (it has various tweaks like jumping between detected faces and stuff but not this simple one button solution so common on many cameras). I will mention that when shooting RAW only, zooming-in the image with the EM5 you see actual pixels and with the G5 you see a lower resolution preview so it get's slightly pixelated enough to make you uncertain that the image is in proper focus (it looks more out of focus than pixelated). I think shooting RAW+JPEG in the G5 might fix it but haven't tried it as the AF is quite good and I can tell if it's properly focused even in the lower-res view (just don't go looking for sharp eyelashes in a portrait image!). Autofocus: The EM5 might be slightly faster (I have no way of measuring this) but is definitely better implemented. For example: I can be in central point AF but if a face is detected it overrides the central point. This is also possible with the G5 but it requires resetting this every time (you choose face detection and then choose to move to center but this setting doesn't stay stuck between modes (PASM) or switching off the camera etc.). The EM5 also has great eye detection which works wonders when shooting portraits with shallow DOF (45 F1.8 for example). The G5 doesn't have eye detection. Video quality: This one's easy - the G5 is much better (try shooting the EM5 with moving leaves, running water, kids running and you'll see the codec feels the frame with a buzzilion blocky artifacts). The EM5 however has the 5 axis IBIS which allowed me to shoot handheld videos with almost zero wobble. But the IQ messed up this advantage sadly. The AVCHD files on the G5 are also easier to combine automatically with short batch files using ffmpeg (the quicktime files from the EM5 sometimes got the colors messed up when combining). Shutter (and shutter shock): To start off I'll say I have no problems with double imaging etc. when shooting the 14-42 PZ between 1/60 to 1/200 shutter speeds. I have tested this and found zero problems @100% magnification on both cameras. But other than that the EM5 has a much softer and quieter shutter than the G5's. The G5 has an optional electronic shutter which is sometimes useful as the image capture is near silent but is limited in some ways (doesn't work with external flashes for one thing). AUTO WB: This might seem less of an issue for RAW shooters such as myself but it's not exactly so. In my LR workflow I have manually set automatic presets for each camera based on the ISO used in the file etc. For the G5 I have AUTO WB set by LR as the in camera auto WB is very 'cold'. On the EM5 I had LR leave the WB as set by the camera and have found that the auto WB done in the EM5 is more to my liking than the auto WB set by LR. Maybe this is part of why EM5 OOC JPEGS seem (and are) so much more pleasing visually than the G5 jpegs. Flash: I mainly use external flashes (I have the Metz 44 AF-1, 50 AF-1 and 24 AF-1). BTW the Metz 24 AF-1 is amazingly useful for indoor flash bouncing and I rarely use the larger 44 and 50 (bought second hand btw). So the lack of built-in flash on the EM5 is less of a limit to me and I also don't care much for the built-in flash on the G5 as it doesn't tilt upwards for a make-do bounce. The flash system is definitely better on the EM5; I can use HSS (with the Metz 50 AF-1), can use wireless flash with TTL (the 44 and 50) but as the wireless feature requires me to attach the clip-on flash (removing 2 covers in the process) I hardly ever used it. What I do like a lot on the EM5 is that I can set a limit for minimum shutter speed in AUTO ISO and even in preset ISOs this dictates the shutter speed when using an external flash without needing to use S or M modes. On the G5 it always uses 1/60 unless I override it using S or M modes. Conclusion: The EM5 is better built (weather sealed etc.), has better major components (sensor, 5-axis stabilizer, EVF shutter and more), has better auto WB and processing, is faster (9 FPS etc.) and by the numbers should be superior to the G5. But when it comes down to actually using one I find the shooting experience to feel less natural with the EM5. Believe me: after over a year I knew where everything was in the menus (from bracketing to anti shock to whatever else) of the EM5 but still find the G5 much easier to manage. The EM5 is so uncomfortable without an external grip (which costs a fortune if you buy the original) whereas the G5 is just fine (and after selling the kit lens which I have no use for) and costs roughly what the HLD6 costs without the camera itself... this alone is very annoying. The only real thing I miss on the G5 is the 5-axis IBIS; no more shooting dimly lit static scenes @ ISO 200, shutter 1/2 second... So anyways - this was a LONG post (don't think I'll be writing anything like this again:smile but I hope it helped as it contains many things not mentioned online and definitely not organized together in the way I wrote in my post. And as a side note: I also have the GX1 (used as a backup for small paid jobs) and find the G5 superior in just about everything except size which is less of an issue when attaching a lens.
