Olympus E-400 versus Olympus E-300

The Olympus E-400 and the Olympus Evolt E-300 are two digital cameras that were revealed to the public, respectively, in September 2006 and September 2004. Both are DSLR (Digital Single Lens Reflex) cameras that are equipped with a Four Thirds sensor. The E-400 has a resolution of 10 megapixel, whereas the E-300 provides 8 MP. Read on to find out how these two cameras compare with respect to their size, their sensors, their features, and their reception by expert reviewers.

Body comparison: Olympus E-400 vs Olympus E-300

An illustration of the physical size and weight of the Olympus E-400 and the Olympus E-300 is provided in the side-by-side display below. Three consecutive perspectives from the front, the top, and the back are presented. All size dimensions are rounded to the nearest millimeter. If you prefer, you can also use the toggle button to switch to a comparison in percentage terms (in this case, the camera on the left side – the E-400 – represents the basis for the calculations across all the size and weight measures).

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Olympus E-300 is notably larger (6 percent) than the Olympus E-400. Moreover, the E-300 is substantially heavier (43 percent) than the E-400. In this context, it is worth noting that neither the E-400 nor the E-300 are weather-sealed.

The above size and weight comparisons are to some extent incomplete since they do not consider the interchangeable lenses that both of these cameras require. In this particular case, both cameras feature the same lens mount, so that they can use the same lenses. You can find an overview of suitable optics in the Four Thirds Lens Catalog.

Concerning battery life, the E-400 gets 500 shots out of its BLS-1 battery, while the E-300 can take 750 images on a single charge of its BLM-1 power pack.

The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators. If you want to switch the focus of the display and review another camera pair, just select a new right or left comparator from among the camera models in the table. Alternatively, you can also move across to the CAM-parator tool and choose from the broad selection of possible camera comparisons there.

The price is, of course, an important factor in any camera decision. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The E-400 was launched at a somewhat lower price (by 13 percent) than the E-300, which makes it more attractive for photographers on a tight budget. Usually, retail prices stay at first close to the launch price, but after several months, discounts become available. Later in the product cycle and, in particular, when the replacement model is about to appear, further discounting and stock clearance sales often push the camera price considerably down. Then, after the new model is out, very good deals can frequently be found on the pre-owned market.


Sensor comparison: Olympus E-400 vs Olympus E-300

The imaging sensor is at the core of digital cameras and its size is one of the main determining factors of image quality. A large sensor will tend to have larger individual pixels that provide better low-light sensitivity, wider dynamic range, and richer color depth than smaller pixel-units in a sensor of the same technological generation. Furthermore, a large sensor camera will give the photographer more possibilities to use shallow depth-of-field in order to isolate a subject from the background. On the downside, larger sensors tend to be more expensive and lead to bigger and heavier cameras and lenses.

Both cameras under consideration feature a Four Thirds sensor and have a format factor (sometimes also referred to as "crop factor") of 2.0. Within the spectrum of camera sensors, this places the review cameras among the medium-sized sensor cameras that aim to strike a balance between image quality and portability. Both cameras feature a native aspect ratio (sensor width to sensor height) of 4:3.

Sensor size

While the two cameras under review share the same sensor size, the E-400 offers a higher resolution of 10 megapixel, compared with 8 MP of the E-300. This megapixel advantage translates into a 12 percent gain in linear resolution. On the other hand, these sensor specs imply that the E-400 has a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 4.74μm versus 5.30μm for the E-300). In this context, it should be noted, however, that the E-400 is a somewhat more recent model (by 1 year and 11 months) than the E-300, and its sensor might have benefitted from technological advances during this time that at least partly compensate for the smaller pixel size.

Neither the E-400 nor the E-300 offer Live View, so that they cannot project the live image that the sensor receives onto the rear screen. Moreover, both cameras are still-image focused and cannot record videos.

Feature comparison: Olympus E-400 vs Olympus E-300

Beyond body and sensor, cameras can and do differ across a range of features. The E-400 and the E-300 are similar in the sense that both have an optical viewfinder. The latter is useful for getting a clear image for framing even in brightly lit environments. The table below summarizes some of the other core capabilities of the Olympus E-400 and Olympus E-300 in connection with corresponding information for a sample of similar cameras. If needed, the dpreview camera hub, for example, contains further detail on the cameras' specs.

Both the E-400 and the E-300 have been discontinued, but can regularly be found used on eBay. The E-300 was replaced by the Olympus E-330, while the E-400 was followed by the Olympus E-410.

Review summary: Olympus E-400 vs Olympus E-300

So how do things add up? Is there a clear favorite between the Olympus E-400 and the Olympus E-300? A synthesis of the relative strong points of each of the models is listed below.


Advantages of the Olympus E-400:

  • More detail: Offers more megapixels (10 vs 8MP) with a 12% higher linear resolution.
  • Larger screen: Has a bigger rear LCD (2.5" vs 1.8") for image review and settings control.
  • More detailed LCD: Has a higher resolution rear screen (215k vs 134k dots).
  • Faster burst: Shoots at higher frequency (3 vs 2.5 flaps/sec) to capture the decisive moment.
  • Less heavy: Is lighter (by 189g or 30 percent) and hence easier to carry around.
  • More affordable: Was introduced into a lower priced segment (13 percent cheaper at launch).
  • More modern: Is somewhat more recent (announced 1 year and 11 months after the E-300).

Reasons to prefer the Olympus Evolt E-300:

In any case, while the comparison of technical specifications can provide a useful overview of the capabilities of different cameras, it says nothing about, for example, the handling, responsiveness, and overall imaging quality of the E-400 and the E-300 in practical situations. User reviews, such as those found at amazon, can sometimes inform about these issues, but such feedback is often incomplete, inconsistent, and biased. This is where reviews by experts come in. The following table reports the overall rankings of the cameras as published by some of the major camera review sites. The detailed reviews can be accessed, respectively, on the websites of cameralabs.com, dpreview.com, ephotozine.com, imaging-resource.com, and photographyblog.com.

The above review scores should be interpreted with care, though. The assessments were made in relation to similar cameras of the same technological generation. Thus, a score needs to be put into the context of the launch date and the launch price of the camera, and comparisons of ratings among very different cameras or across long time periods have little meaning. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
