The Mark IV also features a compact in-body image stabilization unit with up to 4.5 EV steps of compensation and 15 fps high-speed sequential shooting. There’s also improved Continuous AF precision for continuous focusing on moving subjects. Meanwhile, the Face Priority/ Eye Priority AF is now able to focus on faces in profile or looking down, which should help ensure that users can capture sharp portraits even at unconventional angles. The Olympus OM-D E-M10 is the third camera in the company's OM-D range and represents another tier in the lineup - sitting below the E-M5 and the even more expensive E-M1. It uses the same 16 megapixel Four Thirds sensor as the E-M5, though doesn't offer that camera's weatherproofing. From the E-M1 it gets the latest TruePic VII image processor and built-in Wi-Fi connectivity. Clearly, the E-M10 leans on some highly capable genetics. However, the things the E-M10 adds are rather nice - the rear screen is a noticeable improvement, as is the inclusion of the 'Adaptive Brightness' viewfinder technology first introduced in the E-M1. This brightens and darkens the viewfinder panel, based on the ambient lighting conditions. As a result, the viewfinder ends up being bright in bright light without then being blinding in low light. It's a little thing (to the point that you don't necessarily notice it happening), but it helps provide a more OVF-like experience.

In a bid to make the OM-10 cheaper, Olympus compromised on several quality aspects. This includes building the camera with a less durable body, which made the camera more susceptible to damage. Also known in some markets as the OM-PC, the OM-40 had a program mode that automated the selection of both the aperture and the shutter speed. The nucleus of the system was a series of compact bodies divided into an advanced series and a later consumer-oriented series. The first model was the all-mechanical M-1 which, after pressure from Leica (which already had an M1 model), was renamed OM-1. At the same time the M system was renamed OM System. The camera included a full-aperture TTL Cadmium-sulphide (CdS) exposure meter, and a bayonet lens mount of relatively large diameter. By the end of the 1970s it was joined by the semi-automatic OM-2 and consumer-oriented OM-10. Olympus continued the naming pattern with the 'professional' OM-3 and OM-4, and the consumer-level OM-20, OM-30 and OM-40. The cameras were accompanied by a series of Zuiko-branded lenses, as well as a generous selection of accessories. The majority of OM bodies and lenses were manual-focus only; the OM-707 of 1986 was the only true autofocus model. In any case, though, when it comes to image quality, the lens with which you choose to shoot is just as important as the sensor and processor. In this review, I've used the E-M10 IV body with three lenses: The M.Zuiko Digital ED 14-42mm F3.5-5.6 EZ zoom which is available in the E-M10 IV kit version, plus the separately-available 17mm F1.8 and 45mm F1.8 primes. One guy told me that I could basically use more or less any flash, but if I was interested, he wanted to sell me the flash that originally came with the camera. He also had some extra lenses for sale. So, that's how I ended up buying a gorgeous 28 mm f/2.8 wide angle and a 100 mm f/2.8 telephoto for it! I didn't pay much for them, just around €60-70, I think. I didn't buy the flash since I wanted to use my Diana flash with it instead.

Features of the OM-10

Just like its predecessor, the Olympus OM-D E-M10 Mark IV is incredibly lightweight and compact. However, Olympus has managed to shave 27g off the Mark IV, making it even more portable. The trade-off with a light camera tends to come down to the body material used to construct it. The Mark IV is made out of plastic, compared to the metal body of more expensive cameras, such as the Olympus OM-D E-M1 Mark III.

I would love to focus on this being an unapologetically shooting-oriented camera, that puts the fun in photography rather than specs on a spec sheet. I would love this to be a camera I can buy for my girlfriend, so she can join me on days out taking photos without resorting to her phone. OM System has already given us the latest version of the professional Olympus OM-1 in the form of the OM System OM-1, along with the semi-pro OM System OM-5. But the OM-10 was arguably the most beloved of the heritage Oly SLRs –so the inevitable OM System OM-10 is a fresh opportunity to take the principles that made the old film camera great and apply it to modern mirrorless technology. The OM Series lenses had the aperture control ring located at the front of the lens barrel. This was done to move it away from the shutter speed control, which was a ring on the camera body concentric with the lens mount. OM lenses also featured a depth-of-field preview button on the lens, in contrast to most other SLR camera systems, in which the button was placed on the camera body. Being a system, Olympus made numerous accessories for professional portrait, photo journalism, sport photography and scientific photography. [7]

The camera's built-in light meter provides accurate exposure readings through the viewfinder, ensuring well-exposed photographs. It features a center-weighted metering system, which analyzes the light from the entire frame but gives more importance to the central area. If you’re just starting out, there’s certainly nothing wrong with the OM10 but if you want to step it up a level then there are far better SLR cameras out there. What Kind Of Photography Is The Olympus OM10 Best For? Pushing the camera’s ISO sensitivity to its limits, the results were usable, although details begin looking smudged past ISO 6400 when viewed at 100%. The ability to take better pictures in low light is further supported by the camera’s five-axis in-body image stabilization. This manages to keep images sharp when shooting handheld as slow as 1/8th of a second, which is a significant advantage for dimly lit scenes. In 1986 the OM-4 was improved to a tougher OM-4Ti (OM-4T in USA) version, with titanium top and bottom plates, improved weatherproofing and high-speed flash sync. This last version was discontinued in 2002.The OM-2000 had a mechanical, vertical-running shutter in contrast to the traditional OM cameras with their horizontal-running shutter. This allowed the OM-2000 to synchronize an electronic flash at 1/125s. Many photographers found this capability an advantage for the use of "fill flash" in daylight. In 1972, Olympus released the first camera of the OM SLR series, the OM-1, which was followed by the OM-2, OM-3 and OM-4. In 1979, they released the first of their more consumer-targeted series, the Olympus OM-10 which was seen as a less ‘professional’ camera. Not that this mattered, as the camera did in fact go on to be a success, and I can see why. The OM-10 is a manual focus, aperture-priority camera. That means, you’re in charge of focusing and choosing the aperture setting, and the camera figures out what the shutter speed should be. Of the various automatic modes, I find aperture priority the most useful. That’s because I usually don’t care about the shutter speed so long as it’s not so slow that I need a tripod to avoid image blurring. What I do care about though is depth of field, which is selected by changing the aperture of the lens. You might have a different preference, but this is mine.

You could also use a 28mm Zuiko lens or 35mm Zuiko lens depending on how why do you want your shots to be. Either way, these are all brilliant options for the Olympus OM10! Is The Olympus OM10 Fully Manual? I cannot recommend the Olympus OM-10 enough – especially to anyone starting out with film. The only teething problems I had were down to a faulty lens and then having to get my head around shooting with the built in light meter. Aside from those issues, which neither were really the fault of the camera itself, I have had a great experience shooting it. I rate it highly to anyone who asks, it has definitely given me some of my all-time favourite images. 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. The changes to the front grip may be subtle, but it's more secure and keeps your hand positioned further up the camera for additional stability. The thumb grip is substantial and is positioned to keep you from accidentally pressing buttons. The original Olympus OM-10 only had one exposure dial…so why not do it again?

While the E-M10 Mark IV can be used to capture attractive looking video, it's not heavily geared towards video shooters.
