An increase in megapixel count has the potential to increase image noise, as smaller pixels are usually less light-sensitive. However, Olympus has mostly managed to avoid this pitfall, as the E-M10 IV's images contain similarly low levels of image noise to those from the Mark III, and indeed the APS-C Fujifilm X-T200 for that matter. Sony's A6100 doesn't fare quite so well, with its images containing noticeably more noise at higher ISOs. Verdict The OMD EM10 Mark III, like all Olympus OMD and PEN bodies, features built-in sensor-shift stabilisation that works with any lens you attach. The EM10 Mark III inherits the same five-axis stabilisation of its predecessor, which in turn took it from the original EM1; in theory this should offer four or five stops of compensation with almost any lens you mount.

On the upside, the EM10 Mark III also inherits the handy and unique options for long exposure fanatics. First is the ability to dial-in a shutter speed as long as 60 seconds in Manual, which is often long enough for basic long exposure work without the need for any accessories. Panasonic also offers this on its Lumix G cameras, and I find it invaluable. The E-M10 Mark IV certainly delivers in terms of focusing speed and perhaps more importantly accuracy too, with very few false positives in the Single AF mode. The E-M10 doesn't have all the enthusiast trimmings of the E-M1, but it is targeted to a slightly more serious or developing photographer, rather than a casual snapshooter. With a built-in viewfinder, dual control wheels and number of customizable controls, it's aimed for the photographer who wants to take some control over shooting settings, though it does have an Auto mode for shooters not yet ready to take that step. It presents all of the light-and-compact benefits of Micro Four Thirds, with a few more SLR-like touches (viewfinder and direct controls) that an enthusiast will appreciate. A very subtle change can be found on the rear, between the LCD and buttons. It's a small rubberized strip that gives you a little something to hold onto when you're holding the camera at arm's length taking selfies. USB charging
It would also be nice if Olympus made more use of the camera’s touch control system, so it can be used with more of the Super Control Panel and the main menu. The earlier EM10 Mark II offered a wealth of configuration options, including the number of frames from 3 to 999, and the focus differential from one to 10. Now on the Mark III it’s much-simplified: the camera will take eight frames, no more, no less with just the choice of whether the change of focus between shots is large or small. The goal remains the same as before though, to attempt to capture a sequence where the first and last frames are focused on the nearest and furthest points you’d like to be in focus, while also including a bunch inbetween. These should then be loaded into third-party software for assembling.

One of the key new features for the Olympus OM-D E-M10 Mark IV is the welcome addition of a 20MP Live MOS sensor, which is a boost from the previous generation’s 16MP sensor. This brings the E-M10 series in line with the latest versions of the E-M5 and E-M1 series, which are both also using 20MP sensors. The OM System OM-10 is the next camera expected to be announced. Following the transmogrification of the Olympus OM-D EM-1 and E-M5 to the OM System OM-1 and OM-5, now it's the turn of the Olympus OM-D E-M10 Mark IV to be reborn. Take the shot and when shooting RAW and SuperFine (top quality) JPEGs in tandem there's a wait of a more than acceptable one second before the shot is fully committed to the memory card. The E-M10 offers 24 scene modes as well as 12 Art Filters, along with 7 colour presets and custom colour slots – so there’s plenty of scope for experimenting. There are another seven picture colour modes, which sees the camera apply some filtering of its own.In terms of shooting information and guides, the OMD EM10 III cycles through a variety of views using its INFO button, overlaying a live histogram, dual axis leveling gauge, shooting information only, or a clean view. It’s also possible to overlay a selection of alignment grids and lines. In manual focus you can enable focus peaking with or without a magnified view that makes nailing the precise focus a doddle. I’ll discuss this more in the handling section later, but wanted to mention here that the wealth of information, views and guides exceed typical DSLRs and are also available when shooting with the screen or viewfinder.

What makes the Olympus cameras even more unique though are their Live Bulb and Live Time options which let you take regular peeks at the exposure on the screen as it builds-up to see how it’s getting on. This lets you stop the exposure early if it’s already perfect, or perhaps not going to work out. The interval between updates can be set to 0.5, 1, 2, 4, 8, 15, 30 or 60 seconds, and the maximum number of peeks depends on the ISO value: 9, 14, 19 or 24 times for ISOs of 1600, 800, 400 or Low respectively. Once you’ve used up your allocation of peeks, there’ll be no more, regardless of the exposure length. You can find the options to configure this in Custom section D2. The cheapest OM-D, the Olympus OM-D E-M10 Mark III is small, affordable, remarkably powerful and not just suited to beginners but enthusiasts too. If you’re just starting out, or you’re on a tight budget, this is the one to get. Shooting modes include Aperture priority, Art Filter, Manual, Program and Shutter priority, while one-shot echo and multiecho effects can be added to movies. There's also the ability to capture high-speed VGA footage at 120fps. The Olympus OM-D E-M10 Mark IV is a fantastic little camera with plenty to offer. With a new 20MP sensor and improved Continuous Autofocus, the Mark IV boasts some useful upgrades over its predecessor, the Mark III. While the other improvements are admittedly incremental, we’re still impressed with what the Mark IV brings to the table.
Conclusion
The EM10 Mark III also inherits the Keystone Compensation option of recent models which provides real-time correction of converging lines as you compose, although on the Mark III you’ll now find it on the AP menu. There’s nothing stopping you from performing similar skewing after the event, but Olympus likes to offer the chance to do it in the field and I appreciate the chance. Inevitably there’s some cropping of the image and juggling of pixels, but it’s nice to be able to make these corrections in-camera as you compose. Here’s a handheld before and after shot to show you the kind of thing that’s possible with a wide lens pointing upwards taken from exactly the same position, and with the same lens and focal length.

The menu system is similar to that of the professional OM-D E-M1. This is a complex, multi-level menu system that might not seem intuitive at first sight, especially to beginners, so reading the manual is a good idea before starting to explore it. To get started, install the free Olympus Share app on your phone or tablet; it’s available for iOS or Android devices and I tested the latter on my Samsung Galaxy S7. Next tap the Wifi icon in the top left corner of the screen (you may need to press the info button to see it), then the EM10 Mark III will display a QR code on-screen. Despite the increase in sensor resolution, noise levels have also improved a little from the E-M10 III. Noise first starts to become noticeable around ISO 1600, and while some softening is noticeable at ISO 3200, I still found it quite usable. ISO 6400 and 12800 are usable for smaller print sizes in a pinch, but quite a lot of finer detail is lost to noise reduction. ISO 25600 is best avoided for all but very small prints.Unfortunately the E-M10 Mark IV still doesn't combine the shots either in-camera or in the supplied Olympus software, so you'll need to use Photoshop or a specialized software program like Helicon Focus to combine all of the shots into one image. This is nearly as fast as using NFC (Near-Field Communication), a feature that the OM-D E-M10 Mark IV doesn't offer. The last option on this tool bar is an on-board shooting hints and tips manual, with the usual 'suspects' of photographing children and pets given the most prominence ('take a picture at their height level' being a summation of the level of advice imparted). We even get tips, as a bit of closet advertising, for attaching Olympus accessories, such as lens converters. With that being the case, the biggest reason to opt for the E-M10 IV's Raw file format is to allow you to pull up shadow areas in contrasty scenes. I found plenty of scope for correction, so if you're faced with a scene with a wide dynamic range – a sunset, for example – you'll benefit from switching to Raw. Something that hasn't changed much on Olympus cameras over the years are their interfaces. There's the Live Control, which is essentially a shortcut menu, and the somewhat overwhelming Super Control Panel (which can be navigated with your finger: a real timesaver). By default, the camera uses Live Control when you press OK, but you can have it go to the Super Control Panel instead. You can choose which interface is used for Auto, Art Filter, Scene and P/A/S/M modes separately.
