I own both of these now Totally different cameras for sure. This is to be taken with a grain of salt, it is just my own poorly formed impressions Keep in mind I could be wrong about some of this as I am still learning the XE-1. So there is no fanboi-ism here, just my initial impressions. 1) Autofocus OMD's AF blazingly fast for single AF. It focuses in low light areas without the need of the focus lamp, very little hunting. The Continuous AF is not on par with the D7000. XE-1's AF system is best not tested after using the OMD, because compared to the OMD it is laughable. It hunts in low light even with the AF lamp. It seems to work well enough with some decent light around. 2) Customization The OMD is highly customizable, everything from the viewfinder, display, lens function, f1, f2, the list goes on. It is the most customizable camera I have ever had. Almost to the point of making things a bit confusing. It took a while but I now have it set to how I like it, and it is pretty easy to use. You can have the OLED and EFV display different things as well. The Fuji XE1 is nowhere near as customizable. It has ONE function button, but you cannot even use the scroll wheel on the back to control it, you still have to use the thumb pad which means you have to pull it from your eye, seems kind of pointless. I would say this camera is not very customizable, if it were not for the Q button where you can scroll through pre-sets, but I would argue this is not customization, this just enables fast configuration changes. The screen and EFV will show the same info 3) EFV The OMD has a decent viewfinder. It is not very sharp even when adjusted with the diopter, I know it is not my eyes because I read at 20/15 since my Lasik. Very little lag, even in low light. The eye sensor works ok but could stand to be a bit faster. It throws up a nice large image about the same size as the OFV on the D7000. Not sure why but you cannot have the EFV on non-stop, even when shutting off the rear display the EFV is off until the eye sensor is triggered. The XE1 has the same size viewfinder, but higher resolution and you can see the difference. Things look sharper and crisper, no doubt about it. However it is much laggier. The eye sensor is better though, and flips from screen to EFV faster. You can leave the EFV on non-stop with the back off if you like. Build quality The OMD nice solid construction. Not a fan of the dials, the dials do feel a bit cheap. Weather sealed which is awesome! The XE-1 also has a nice feel to it, but not as nice as the OMD. However the dials feel much better and more secure. Ergonomics OMD is not bad, it is a small camera, with small buttons a bit mushy because of the weather sealing but that does not bother me. Without the grip it is ok for lighter lenses. I have the Panasonic 12-35 on mine and it really needs the grip. Let’s talk about the grip too, it really helps, but the bottom corner of it sort of digs into my palm on the large area at the base of the thumb. The battery grip helps, but I have been considering machining out a plate to attach to the bottom with a curved surface to help remove the bottom corner. The memory card is on the side which I prefer so you don’t have to detach it from a tripod plate to swap out the memory card. Dials and buttons are well laid out in a nice intuitive manor XE-1 Better IMO ergonomically. The 18-55 kit lens has some heft to it, but it still seems to balance without the need of a grip. The buttons are larger, fairly flush but stick out just enough. It is pretty comfortable to hold. I like how the viewfinder is not in the middle like the OMD, this means I don’t have to bump my nose in the screen. The dials and buttons are very well laid out. The memory card sits in the battery compartment like the NEX, I don’t like this. it is also in the back next to the door and sort of annoying to pull out. Image quality This horse has been beaten to death. You can find TONS of sample images and pixel peeping online. Basically 95% of the time the OMD will be more than good enough for what you need. The XE-1 in my opinion IS better, but not by a substantial amount. However one area the XE-1 shines is HIGH ISO. 6400 is perfectly usable on the XE1, but not the OMD. In fact, ISO 12,800 looks pretty good on the XE-1. Cool stuff specific to each camera. OMD - Highlights and Shadows. How cool is this? it shows you live where you are clipping. I always have it ON with the OMD. I really like that feature OMD- Articulating screen. I was not a fan of the idea when this became popular, gotta admit, I have started to like it. XE-1 - DOF and manual focus bar. This is AWESOME. There Is a bar at the bottom of the screen/efv that indicates distance, there is a red line surrounded by a white bar that indicates the focus point. The red line is the exact center of the focus, the white bar shows you the depth of field. So when opening the aperture up the white bar expands to show the area that will be in focus. Using this you can manually focus in very low light with only knowing the approximate distance to the subject. XE-1 film simulation modes. I know I know, the OMD has Art modes. However to be honest, my personal opinion is most of the art modes are just stupid and I will never use them, they are too over the top, the only one I kind of like is the Dramatic Tone. The film simulation modes are just more subtle and does not look like it was heavily processed, it still looks like a natural photograph. XE-1 Pop up flash. I dig it, it is low powered, probably just enough to kick up shadows a bit in harsh sunlight conditions or to nudge up the shadows a bit on a backlit situation. It goes INTO the camera and gets out of the way. you can also use it for bounce in smaller rooms. The OMD just has that goofy/stupid attachment flash that requires you to remove 3 separate plastic covers which can get lost. XE-1 Aperture ring! yes! I love the way this camera is setup. The shutter dial, aperture ring, give it a very nice feel. XE-1 High end kit lens? Yes! This kit lens is awesome! it has a wonderful feel, metal construction, very very smooth and competent feel to the focus and zoom rings. Due to it being a variable aperture lens there is no hard stops on the aperture ring, but it does feel very good. In the end these are two very different cameras and do not make for a good comparison. The OMD is a Ninja, it is a Jack of all Trades and master of many, it is fast, efficient with excellent image quality. It is a finely engineered marvel of photographic joy. The Fuji XE-1 was clearly designed as a fun camera geared towards photographers. It takes more care and thought, and seems to have been intended with more of an artistic purpose. It has a lot of personality to it. The differences between the two really balance each other out, and I recommend them as a set. They are so different they almost feel natural together. As for which is better that depends on what you are into. If you need high speed system for fast changing environments the OMD is probably the better choice. The Fuji seems to be more of an artist’s tool intended for deliberate shooting. Even though I will probably use the Fuji more than the OMD, I will probably take far more pictures with the OMD than the XE-1. I feel the OMD us something I will "use", the Fuji will be something I "work with". If I were only allowed to keep one, it would certainly be the XE-1. It really seems to hit what I want to do with my photography which is very slow and deliberate. If you are into wildlife, sports, etc., the OMD would be a better choice. In fact, for many people I think the OMD will be a better choice.
