Product Description

The OM-D E-M1 interchangeable lens camera is now the flagship of Olympus's Micro Four Thirds lineup. Rather than calling it the follow-up to the E-M5, Olympus says that the E-M1 is actually the 'successor' to the E-5, a Four Thirds DSLR introduced back in 2010. The E-M1's 16.3-megapixel Live MOS sensor has on-chip 37-point phase detection, which allows the E-M1 to focus legacy Four Thirds lenses (using the optional MMF-3 adapter) at much faster speeds than previous Olympus m4/3 cameras. When you're using Micro Four Thirds lenses, focusing is handled by the EM-1's 81-point contrast detect AF system.

The EM-1 is weather, dust, splash and freezeproof, with a large high resolution touch LCD and electronic viewfinder. It retains the E-M5's built-in 5-axis image stabilization, plenty of customizable controls, and Wi-Fi image transfer and camera controls via Olympus's Image Share 2.0 smartphone app.

Overall Score

In most respects the E-M1 does a good job bridging the gap between a traditional DSLR and a Micro Four Thirds camera. Its controls and customizability may overwhelm less hands-on users, but those who don't mind tinkering will love its flexibility. The improved autofocus tracking and performance with original Four Thirds lenses adds to the appeal of a camera with blazingly fast AF acquisition speeds with its native lenses.

Good For

Those who prefer viewfinder shooting, want a relatively compact system camera without sacrificing external controls of a DSLR.

Not So Good For

    About a month with EM1

    Some comments after about 1000 shots... Built is good, and also the ergonomics with bare hands. Not so much with gloves - but I have never used a camera that has been handy with thick gloves or mittens. Problem in wintertimes... Maybe the extra grip (coming somewhere) will help a bit. Focusing with FT-lenses is reasonable fast and reliable. So far I have used 9-18, 12-60, PL25, Zuiko 50mm macro, Sigma 50mm, 50-200 aone and with EC14. Fastest are the 9-18 and 25mm - no suprice there. But all ...

    EM-1 and FT 150 2/50 2: AF performance with static subjects and E-3/E-5

    I have posted parts of this in another thread but it may be worthwhile for other people less interested in the OP's issue. My first impression from an EM-1 Oly promotional event is as follows: - I had more FT lenses available but due to time constraints and the usual talks with Oly staff and other people I only tested the 150 f2 and 50 f2. - I started with S-AF and the 150 and felt somewhat unhappy in not so good light until I switched the EM-1 to eye recognition-AF and did some portraiture ...

    Olympus E-M1 from my POV

    I have this camera for about a month now and have been taking it to shoot on weekends to learn and get used to its new features and capability. This is the first mirror-less camera for me from the E-5 so I was overwhelmed with the way the menu and button customization work on these smaller space mirror-less. Simple task such as saving "Myset" took me some time to figure out with the helps from people on DPR forum. This does not work the same way the E-5 does; You have to assign the saved ...

    Zuiko FT + EM1 = Excellent

    Being an olympus user with many ZD SHQ lens, I have been waiting for this moment. An MFT with AF speed that can match FT lenses, with addition to image quality and other improvements. A perfect combination (yet, until EM2 born…).Definitely Improved: AF, IS sensor, Noise, Wifi, and many others. Honestly, Olympus should announce these improvement more open to the public. But as always, Olympus marketing never say much…. Anyway, I gave up my EM5, and start my day with EM1 and Fourthird lenses ...

Questions & Answers


E-M1 - how do you choose which face to focus on with face detection?

My dilemma is whether to use normal single AF point to focus on people or to use face detection. I'd like to use face detection but I can't choose which face the camera to focus on when it detects more than one. I may like to take two separate shots - with focus on the closer and on the further away face. Is there a way to guide the camera to the desired face? Sometimes I also have constant difficulty acquiring focus on people in low light (like f1.4, 1/200", ISO 1000-2500). In 50% of my recent shots at a particular ceremony I had constant back-focus with the 25mm f1.4  - 4-5cm behind the eyes. That is very disheartening because the contrast detect focus is supposed to be the most accurate. I had the same problem with the 75mm f1.8. The Panasonic 35-100 did flawlessly in this respect - tack sharp. If you have an advice on this issue as well, I'd very much appreciate your input.

This is probably not a great answer, but at a party the other night, I resorted to using the touch screen to focus on the right person and shoot. It worked pretty well and I think I may have appeared less intimidating while looking at the tilted screen. Continue Reading

I tried focusing with touching the screen but that overrides the face detection. I want to be able to use the cursors to switch between the marked faces. I think this is the best way to control it. Also it can be made to prioritize the face closest to the chosen focus point. Come on, Olympus! Aren't there any photographers to consult you on these things? It's important! Continue Reading

Olympus OM-D E-M1 low light auto focus performance

Hello, I recently bought a E-M1 and I am quite disappointed with the low light auto focus performance. The camera can basically focus to anything as long as there is a bit of light left but the speed gets down a lot starting at around EV 5 and darker. I compared it to my Panasonic Lumix GH2 that I still own and I posted a video at Youtube: Video Is my camera buggy? Is someone else also experiencing slow AF when using the E-M1 not in daylight? Is there a way to speed it up? AF light is set to on of course in the camera. Any help is greatly appreciated!

I have an EM1 and a GX7. While there are things I like more about the EM1 AF (face detection, for example, where the "near eye" focus option is just incredibly effective), the GX7 is notably more sure footed focussing in low light, particularly very low light, where the EM1 gives up well before the GX7. This is assuming the same lenses and apertures of course... Which is not to say the EM1 is anything other than excellent in low light - I haven't seen anything like the OP on this. But the GX7 is better... -Ray -------------------------------------- http://www.flickr.com/photos/20889767@N05/ Continue Reading

Yes they does ;) GX-7 focuses down to -4 EV. "The AF remains contrast-based, but is faster than the GX1 with a 240fps drive system and the GX7 will also focus in very low light down to -4EV." Source: Cameralabs.com Continue Reading

I believe that both the new GX7 and GM1 are also capable of focusing down to -3EV even if slightly slower than when brighter. Continue Reading

A7 vs OM-D E-M1 speed?

Hi, I am not a professional photographer but a keen amateur. Today I tried out the A7 and OM-D E-M1 primarily to see the size difference as I had read the OM-D was 'much' larger than normal m43 cameras but A7 reviews had failed to mention this. Anyhow, I was surprised that they were both almost identical sizes and I found both a joy to hold and use. The one thing that surprised me and I'd like to canvas opinion on was the speed with which the cameras were ready to take another shot. The OM-D was ready almost instantaneously and you could rattle off 2, 3, 4 etc. really quickly whereas the A7 took about 1 to 1.5 secs (rough guess) to be ready to take the next shot. Is this purely down to processing the extra pixels? It seemed odd to me and was a disappointment with an otherwise stunning camera. Do other A7 owners find this 'lag' or was something not set correctly on the store demo? Your input is greatly appreciated. Thanks, Tom

As far as back to back shots, I have no issue shooting RAW waiting on the A7. I have instant review turned off (blocks out viewfinder too long). To me it feels very quick. I haven't used the EM1. In contrast, my Samsung NX300 is comparatively slow shooting, a bunch of RAW shots in a row and the camera will be processing for some time before it is ready again (it is much better than the older NX cameras, not bad, but the difference between a consumer camera and a pro camera). So I don't think you would have an issue on the A7 shooting quickly, maybe not sports, but for firing off a quick burst of 5 shots during a portrait shoot (5 is just a random number, it will fire as quick as I press the shutter), and keep going without the camera freezing up.

No, it's normal. Steve Huff mentionned it in his review: http://www.stevehuffphoto.com/2013/11/29/the-sony-a7-and-a7r-camera-review-by-steve-huff/ "These cameras do indeed feel slower than an Olympus E-M1 or RX1 in use and I kind of compare them to shooting medium format. Slow paced and steady. Aim, compose, fire. These are not the cameras for sports shooters or machine gun blazing shutter crazies as they are not." "I like the build, the feel, the design and the features but I think the response is just not there when compared to my Olympus E-M1, which is lightning fast in response. I have been shooting that E-M1 like mad and when I switched it up to the A7 and A7r it seemed like I was working in slow motion..and I am not talking about AF, just overall response time of the camera."

I read ear some bad reviews on the a7 focusing and I was pleasantly surprised at how well it focuses and also in low light. As much has to do with the lens as the camera. The 75-300mm on my E-M1 in low light hunts a lot. To be honest I have no issues with the focus. I have had much slower over the years and got by fine. The high ISO pictures from the a7 blows the E-M1 out of the water. Full frame at $2000.00. It's a better bargain than the $1300.00 E-M1 Continue Reading
