Olympus OM-D E-M10 Mark IV Sample Photos

Sample Photos - As expected with an Olympus camera, the JPEG output from this camera is very good, with excellent colour reproduction, and good levels of sharpness straight from the camera. You can leave the colour settings on Auto, and let the camera decide the best settings, or alternatively, you can set this yourself. You can also adjust sharpness, contrast and saturation for these.

Exposure is generally spot-on, and the camera does a great job of capturing dynamic range in images on default settings.

Panoramic shooting is available in the Advanced Photo mode menus. You'll also find Live composite, Live time, multiple exposure, HDR, silent, AE bracketing and more. Silent shooting is available in all shooting modes. There's a new Live Boost On2 settings designed to help at night, and the OI.Share mobile app now has a Night View mode.

Focus is said to be improved, and we didn't have any problems with focus when we were using the camera. Face and eye-detection AF works well, and we had 1 out of 12 shots where the camera slightly missed the eyes for focus (8%).

Lens correction is built-in to the camera, with this being automatically corrected in both JPEG and RAW images (and you're unlikely to see uncorrected images in most raw processing software). The lens you use will affect your results, and you will tend to get better results with a prime lens over some of the kit lenses available.
 

 

Olympus OM-D E-M10 Mark IV ISO test images

ISO Noise Performance - The standard ISO range is ISO200 to ISO25600, but this can be extended down to ISO100 (Low). This results in a slight loss of dynamic range.

Noise is low between ISO100 and ISO800, with some noise creeping in at ISO1600. Noise reduction does a good job controlling noise at ISO3200, however, fine detail has reduced at this speed. Noise at ISO6400 isn't too intrusive, and results could still be useful for use on the web (resized), depending on your needs. Noise becomes stronger again at ISO12800, and it's likely you won't want to use this speed, unless you have no other option. Colour saturation remains good however even at ISO12800. ISO25600 is best avoided.

You can adjust the noise reduction options, and you may want to set this to Low rather than normal/standard if you want a little more detail, albeit with a slight increase in noise. These photos were taken on the default settings.

 

Olympus OM-D E-M10 Mark IV White-balance test images

White Balance Performance - When using Auto White Balance (AWB), you can use the "Keep Warm" On or Off setting to set whether you want your shots to retain the warm ambience of the scene (such as candlelight, or warm tungsten lighting, with Warm On), or give a slightly more accurate white balance, which will be particularly useful for product shots (with Warm Off), however for best results the Tungsten preset works very well under Tungsten lighting. Under fluorescent lighting, the AWB performs very well, with the fluorescent preset giving a slight colour cast. AWB is excellent outdoors and it's rare that you will need to adjust the white balance.

 

Olympus OM-D E-M10 Mark IV Digital filters

Digital Filters - There are numerous art filters, including vintage (x3), and instant film, some of our favourites. You can also adjust further settings for most of the art filters, to create something different, with frame options, as well as vignette options (depending on the filter). You can also apply them to photos you've already taken with the in-camera raw editing option.

 

Video - 4K UHD video is recorded at 30/25/24fps, and the camera's in-body image stabilisation (IBIS) helps keep video stable and steady even when using the camera handheld. It certainly beats having no in-body image stabilisation, however, it doesn't quite match the image stabilisation on offer from the E-M5 III or E-M1 III. You can enable digital image stabilisation, although this will add a slight crop.

The lack of a microphone socket could be an issue for some vloggers, and the selfie screen will be blocked when you're using the camera on a tripod or monopod, or selfie-stick or vlogging grip. However, the ability to use the screen for vlogging certainly helps if that's what you want to use the camera for.

High-speed video is recorded at 720p, and 120fps, disappointingly not in FullHD resolution.

Video quality is good with good exposure, focus, and image stabilisation, producing a good looking image with pleasing colour reproduction, and there's plenty of detail in 4K footage. However, in low-light, the camera is likely to struggle compared to other cameras with a larger sensor, or larger pixels (like the GH5S).

With the latest rumours that JIP are going to focus on Pro stuff this rather special little camera line may be coming to an end. I do hope not and it is spared. It fixes the electronic shutter being exiled in to a special mode so more back on course.
