Olympus E-P1 Review

Image Quality


All of the sample images in this Review were taken using the 12.3 megapixel Super Fine JPEG setting, which gives an average image size of around 7Mb.

During the review, the Olympus E-P1 produced photos of excellent quality. Noise is very well-handled, being virtually absent from ISO 100-800 and not being too obvious at the relatively fast speed of ISO 1600. At the fastest settings of ISO 3200 and 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.

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. Shadow Adjustment Technology helps make the most out of the shadows in a high-contrast scene, so you can safely expose for the highlights. The art filters quickly produce special effects that would otherwise require you to spend a lot of time in the digital darkroom, while the 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 camera 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. We did miss having a built-in flash - you'll have to buy the optional external flashgun to take advantage of the E-P1's various flash modes.

Noise

There are 7 ISO settings available on the Olympus E-P1. 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:

JPEG

File Quality

The Olympus E-P1 has 4 different JPEG file quality settings available, with SuperFine being the highest quality option, and can also shoot in RAW format. Here are some 100% crops which show the quality of the various options, with the file size shown in brackets.

SuperFine (7.5Mb) (100% Crop)

Fine (5.5Mb) (100% Crop)

   

Normal (2.4Mb) (100% Crop)

Basic (1.7Mb) (100% Crop)

   

RAW (11.8Mb) (100% Crop)

 
 

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)

   

Night

The Olympus E-P1 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 20 seconds, aperture of f/11 at ISO 100. We've included a 100% crop to show what the quality is like.

Image Stabilisation

The Olympus E-P1 has an Image Stabilisation mechanism built into the camera body, which allows you to take sharp photos at slower shutter speeds than other digital cameras. To test this, I took 2 handheld shots of the same subject with the same settings. The first shot was taken with Image Stabilisation turned off, the second with it turned on. Here is a 100% crop of the image to show the results. As you can see, with Image Stabilisation turned on, the images are much sharper than when it's turned off. This feature really does seem to make a difference and could mean capturing a successful, sharp shot or missing the opportunity altogether.

Shutter Speed / Focal Length

Image Stabilisation Off (100% Crop)

Image Stabilisation On (100% Crop)

Shadow Adjustment Technology

Similarly to Nikon's D-lighting, Sony's DRO etc., Shadow Adjustment Technology (SAT) brightens the shadows in a high-contrast scene without affecting the midtones or the highlights, with four settings on offer via the Gradation menu option. Although this option is always at your disposal, remember that it is meant to be used in strong, contrasty lighting at base ISO. Below you can see a comparison of Normal and Auto gradation; the difference is noticeable in the shadowed areas on the left side of the photo. Two other, special-use gradation settings are available on the camera, Low Key and High Key. The former is for photographing dark subjects against dark backgrounds, whereas the latter is for light-toned subjects against a light-toned background.

Art Filters

The Olympus E-P1 offers six 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. The six available Art Filters are shown below in the following series, which demonstrates the differences. Note that applying the Art Filters slows the camera down somewhat as the camera takes several seconds to process and save the image.

Soft Focus

   

Pale&Light Color

Light Tone

Picture Modes

Olympus' Picture Modes, similarly to Nikon's Picture Styles and Canon's Picture Controls, are preset combinations of different sharpness, contrast, saturation and colour tone settings. The five available Picture Controls are shown below in the following series, which demonstrates the differences. There is also an additional Custom style so that you can create your own look.

Vivid

Natural

   

Muted

Portrait

   

Monotone
