This is a phenomenal camera - it works in every situation I've needed it to. The controls are laid out perfectly for my hands and the fact that the placement is identical for both vertical and horizontal shooting is a major plus! (And one of the reasons I chose this model.) The weather sealing is a feature which can not be oversold. I've shot in both heavy rain and in a blinding snow storm in just the first few months I've owned it....and it held up way better in the elements than this old photographer did. For my purposes I can't imagine how this camera can be improved upon but I'm anxious to see Olympus try!

I have owned a number of different cameras in various formats over the years, including full frame. The Olympus OM-D E-M1X is simply the finest camera that I have ever had the pleasure to use. The ergonomics and handling are outstanding. Even though the E-M1X is considered ‘large’ by micro four thirds standards, it is extremely comfortable to use for extended periods. I have never seen in all my career a camera that addresses pretty much all photographic situations (high res mode: handheld and tripod, super fast processing with dual processors, live ND, the best of the best weather sealing in the industry, robustness, accurate and lightning fast focus acquisition and the best IBIS in the industry. The 20MP sensor in the E-M1X is excellent and bring about the right balance between image quality and file size. If I need more resolution, high res mode is there to support me. I must also say the the Olympus PRO lens are in a different class as far as craftsmanship and resolution. I own the 17mm, 25mm and 45mm (all f1.2) plus the 40-150mm f2.8 and I am absolutely amazed by the ergonomics and file qualities wide open. <br /> <br />I highly recommend the Olympus OM-D E-M1X. It's a piece of equipment that I will keep using in any conditions with pride and confidence.

Update: After 6 months of ownership I have been completely satisfied with my first OM-D E-M1X. After considering various OM-D options for a back-up camera for my client video business, I decided to purchase a second E-M1X. This is simply the finest, most capable, and innovative camera that I have ever owned. Nothing else compares. <br /> <br /> <br />--- Original Review: A superb camera in so many ways --- <br /> <br />I have owned a number of different cameras in various formats over the years, including full frame. The Olympus OM-D E-M1X is simply the finest camera that I have ever had the pleasure to use. <br /> <br />The ergonomics and handling are outstanding. I am out with my camera regularly for 6 to 8 hour time periods doing client video/photo assignments or my own field work for personal projects. Even though the E-M1X is considered ‘large’ by micro four thirds standards, it is very comfortable to use for extended periods. I never get fatigued even after full days of hand-held use. <br /> <br />It is true that a micro four thirds sensor does not have the low light performance, dynamic range or colour depth of a full frame sensor. The 20MP sensor in the E-M1X is excellent, and more than good enough for my varied needs. I have no hesitation at all shooting my E-M1X up to ISO-6400 in RAW. <br /> <br />I love the overall design of the E-M1X. This is a camera that was engineered by folks that understand what professional photographers want and need. The dual grip design is excellent and provides comfort in both landscape and portrait orientations. Button placement is logical and very functional. Even though I have never owned an Olympus camera before I was able to become accustomed to the control placement by the second day of use. <br /> <br />The E-M1X is a technological chameleon. I absolutely love the flexibility of this camera! The E-M1X is packed with special features like Live ND, Keystone control, Pro Capture and the Hand-held Hi Res Mode. Some reviewers view these as little more than gimmicks. From my perspective these are all wonderfully practical features that allow me to do my work faster and better. <br /> <br />Of special note are Pro Capture and Hand-held Hi Res. Without a doubt Pro Capture has allowed me to capture photographs of birds that few other photographers can get with confidence. I regularly use the Hand-held Hi Res Mode for landscape, flower, still life, birds and other animal subjects. I’ve even been able to get very good results when shooting hand-held hi res macro images with the M.Zuiko 60 mm f/2.8 macro lens. Obviously timing and technique are important… but this is a fantastic feature that gives photographers the ability to create 50 MP hand-held hi res images when they need them. If you do tripod work the Hi Res mode produces wonderfully detailed 80 MP images. The hi res modes also do a wonderful job dealing with noise, even at ISO-6400. <br /> <br />The auto focusing is quick and accurate. The E-M1X is the only camera I’ve ever owned that made me feel confident when photographing swallows in flight. The AF point joystick is quick and easy to use. Battery life is excellent and I have been regularly able to capture more than 2,500 bird-in-flight images and still have plenty of battery life left. The frame rates are ideal for the work that I do, and were important purchase criteria for me. <br /> <br />I’ve read some reviews that complain about issues like the resolution of the rear screen and EVF. These strike me as quite petty complaints given the other amazing capabilities and features of the E-M1X. <br /> <br />The OM-D E-M1X is the first interchangeable lens Olympus camera that I have ever owned. I married it up with the trio of M.Zuiko PRO f/2.8 zoom lenses, as well as the 60 mm f/2.8 macro. Overall, my kit is relatively small and light. It provides me with all kinds of flexibility when doing personal as well as client work. Having this much photographic/video power in a kit that weighs less than 3 KG in total is incredible. <br /> <br />For photographers/videographers like me who hate to use a tripod and other camera supports, the E-M1X is a godsend. The IBIS in the E-M1X is simply superb and far surpasses anything else that I’ve used. When using M.Zuiko lenses like the 7-14 mm f/2.8 and 12-40 mm f/2.8 multiple second hand-held images are easily done. The E-M1X makes shooting hand-held video a practical reality. <br /> <br />Overall build quality of the OM-D E-M1X is superb. As soon as you hold this camera in your hands you can feel the quality and ruggedness. No doubt… this is a professional piece of kit. <br /> <br />Pigeonholing the Olympus OM-D E-M1X as a ‘sports and wildlife’ camera does it a great disservice. The E-M1X is an incredibly well-rounded, time saving, professional piece of gear that excels with all kinds of subject matter… in all kinds of shooting conditions. <br /> <br />It is impossible to fully appreciate the capabilities and ergonomics of the Olympus OM-D E-M1X until you actually hold it in your hand and use it out in the field. When you do… you will understand the power of this camera. But… be forewarned. If you do use the E-M1X for a little while you stand a very good chance of getting hooked on it! There simply is nothing else out there that can do everything that the OM-D E-M1X can do.
