Olympus E-PM1 Review

Image Quality


All of the sample images in this Review were taken using the 12.3 megapixel Fine JPEG setting, which gives an average image size of around 5.5Mb.

The Olympus E-PM1 produces photos of excellent quality. Noise is very well handled, being virtually absent from ISO 200-1600 and not being too obvious at the relatively fast speed of ISO 3200. At ISO 6400, noise is easily detectable when viewing images at 100% magnification on screen, but the images are still perfectly usable for small prints and resizing for web use. The fastest setting of ISO 12800 looks good on the specification sheet, but proves much less so in reality.

Colours were vibrant without being over-saturated in the default Natural picture mode, and you can always choose Vivid if you want even more punch. The 6 art filters quickly produce special effects that would otherwise require you to spend a lot of time in the digital darkroom, while the various Picture Modes provide a quick and easy way to tweak the camera's JPEG images.

Image stabilisation via the camera body is a very useful feature that works well when hand-holding the E-PM1 in low-light conditions or when using the telephoto end of the zoom range. The 12.3 megapixel images were a little soft straight out of the camera at the default sharpening setting and ideally require some further sharpening in an application like Adobe Photoshop, or you can change the in-camera setting. The built-in flash takes full advantage of the E-PM1's various flash modes, with good exposure and no red-eye.

Noise

There are 7 ISO settings available on the Olympus E-PM1. Here are some 100% crops which show the noise levels for each ISO setting, with JPEG on the left and the RAW equivalent on the right:

Sharpening

Here are two 100% crops which have been Saved as Web - Quality 50 in Photoshop. The right-hand image has had some sharpening applied in Photoshop. The out-of-the camera images are just a little soft at the default sharpening setting and benefit from some further sharpening in a program like Adobe Photoshop. You can also change the in-camera sharpening level to suit your tastes by changing the Picture Modes.

Sharpened (100% Crop)

   

Flash

Here are some portrait shots. As you can see, neither the On or the Red-eye Reduction settings caused any red-eye.

Night

The Olympus E-PM1 lets you dial in shutter speeds of up to 60 seconds and has a Bulb mode as well for exposure times as long as 30 minutes, which is very good news if you are seriously interested in night photography. The shot below was taken using a shutter speed of 15 seconds at ISO 200. We've included a 100% crop to show what the quality is like.

Image Stabilisation

The Olympus E-PM1 has an anti-shake mechanism, which allows you to take sharp photos at slower shutter speeds than normal. To test this, I took 2 handheld shots of the same subject with the same settings. The first shot was taken with anti shake turned off, the second with it turned on. Here are some 100% crops of the images to show the results. As you can see, with anti shake turned on, the images are sharper than with anti shake turned off.

Art Filters

The Olympus E-P3 offers 6 different Art Filters, which allow you to quickly apply an artistic effect to a photo before taking it (JPEG images only). The most useful of these is Soft Focus, because the FourThirds system lacks a dedicated soft focus lens, and the effect would require advanced knowledge of layers, blurring methods and blending modes if you were to reproduce it in post-processing. Note that applying the Art Filters slows the camera down somewhat as the camera takes several seconds to process and save the image.

Picture Modes

Olympus' Picture Modes are essentially pre-set combinations of saturation, contrast and sharpness, except for the i-Enhance mode that aims to optimise each photo individually. You can tailor each Picture Mode to your needs. The following examples demonstrate the differences across the available Picture Modes.
