Body comparison

The physical size and weight of the Olympus E-300 and the Sony H300 are illustrated in the side-by-side display below. The two cameras are presented according to their relative size. Three successive views from the front, the top, and the rear are shown. All width, height and depth measures are rounded to the nearest millimeter.

Size Olympus E-300 vs Sony H300
Compare E-300 versus H300 top
Comparison E-300 or H300 rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Sony H300 is notably smaller (9 percent) than the Olympus E-300. In this context, it is worth noting that neither the E-300 nor the H300 are weather-sealed.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the H300 has a lens built in, whereas the E-300 is an interchangeable lens camera that requires a separate lens. Attaching the latter will add extra weight and bulk to the setup. You can compare the optics available for the E-300 and their specifications in the Four Thirds Lens Catalog.

The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones. If you want to switch the focus of the display and review another camera pair, you can move across to the CAM-parator tool and choose from the broad selection of possible camera comparisons there.

Any camera decision will obviously take relative prices into account. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The H300 was launched at a lower price than the E-300, despite having a lens built in. Normally, street prices remain initially close to the MSRP, but after a couple of months, the first discounts appear. 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.

Sensor comparison

The size of the sensor inside a digital camera is one of the key determinants 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 associated with larger, more expensive camera bodies and lenses.

Of the two cameras under consideration, the Olympus E-300 features a Four Thirds sensor and the Sony H300 a 1/2.3-inch sensor. The sensor area in the H300 is 88 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 2.0 and 5.6. Both cameras feature a native aspect ratio (sensor width to sensor height) of 4:3.

Olympus E-300 and Sony H300 sensor measures

Despite having a smaller sensor, the H300 offers a higher resolution of 19.9 megapixels, compared with 8 MP of the E-300. This megapixels advantage comes at the cost of a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 1.19μm versus 5.30μm for the E-300). However, it should be noted that the H300 is much more recent (by 9 years and 4 months) than the E-300, and its sensor will have benefitted from technological advances during this time that make it possible to gather light more efficiently. Coming back to sensor resolution, it should be mentioned that the H300 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

The resolution advantage of the Sony H300 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the H300 for good quality output (200 dots per inch) amounts to 25.8 x 19.3 inches or 65.4 x 49.1 cm, for very good quality (250 dpi) 20.6 x 15.5 inches or 52.3 x 39.3 cm, and for excellent quality (300 dpi) 17.2 x 12.9 inches or 43.6 x 32.7 cm. The corresponding values for the Olympus E-300 are 16.3 x 12.2 inches or 41.5 x 31.1 cm for good quality, 13.1 x 9.8 inches or 33.2 x 24.9 cm for very good quality, and 10.9 x 8.2 inches or 27.6 x 20.7 cm for excellent quality prints.

The Olympus Evolt E-300 has a native sensitivity range from ISO 100 to ISO 400, which can be extended to ISO 100-1600. The corresponding ISO settings for the Sony Cyber-shot DSC-H300 are ISO 80 to ISO 3200 (no boost).

Technology-wise, both cameras are equipped with CCD (Charged Coupled Device) sensors. Both cameras use a Bayer filter for capturing RGB colors on a square grid of photosensors. This arrangement is found in most digital cameras.

E-300 versus H300 MP

Consistent information on actual sensor performance is available from DXO Mark for many cameras. This service is based on lab testing and assigns an overall score to each camera sensor, as well as ratings for dynamic range ("DXO Landscape"), color depth ("DXO Portrait"), and low-light sensitivity ("DXO Sports").

Review summary

So how do things add up? Is the Olympus E-300 better than the Sony H300 or vice versa? Below is a summary of the relative strengths of each of the two contestants.

ilogo

Reasons to prefer the Olympus Evolt E-300:

  • Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
  • Better image quality: Features bigger pixels on a larger sensor for higher quality imaging.
  • Richer colors: The pixel size advantage translates into images with better, more accurate colors.
  • More dynamic range: Larger pixels capture a wider spectrum of light and dark details.
  • Better low-light sensitivity: Larger pixels means good image quality even under poor lighting.
  • Easier framing: Has an optical viewfinder for image composition and settings control.
  • Faster shutter: Has higher mechanical shutter speed (1/4000s vs 1/1500s) to freeze action.
  • Faster burst: Shoots at higher frequency (2.5 vs 0.8 flaps/sec) to capture the decisive moment.
  • More flexible: Can take a variety of interchangeable lenses, including specialty optics.
  • Longer lasting: Can take more shots (750 versus 350) on a single battery charge.
  • Better lighting: Features a hotshoe and can thus hold and trigger an external flash gun.
  • Greater peace of mind: Features a second card slot as a backup in case of memory card failure.
  • More heavily discounted: Has been available for much longer (launched in September 2004).

ilogo

Advantages of the Sony Cyber-shot DSC-H300:

  • More detail: Has more megapixels (19.9 vs 8MP), which boosts linear resolution by 58%.
  • Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
  • Broader imaging potential: Can capture not only stills but also 720/30p video.
  • Larger screen: Has a bigger rear LCD (3.0" vs 1.8") for image review and settings control.
  • More detailed LCD: Has a higher resolution rear screen (460k vs 134k dots).
  • Ready to shoot: Comes with an integrated lens, while the E-300 requires a separate lens.
  • Less heavy: Has a lower weight even though it has a lens built in (unlike the E-300).
  • Sharper images: Has stabilization technology built-in to reduce the impact of hand-shake.
  • Easier file upload: Has wifi built in for automatic backup or image transfer to the web.
  • More affordable: Was introduced at a lower price, despite coming with a built-in lens.
  • More modern: Reflects 9 years and 4 months of technical progress since the E-300 launch.

If the count of individual advantages (bullet points above) is taken as a guide, the E-300 emerges as the winner of the contest (13 : 11 points). However, the pertinence of the various camera strengths will differ across photographers, so that you might want to weigh individual camera traits according to their importance for your own imaging needs before making a camera decision. A professional sports photographer will view the differences between cameras in a way that diverges from the perspective of a street photog, and a person interested in family portraits has distinct needs from a landscape shooter. Hence, the decision which camera is best and worth buying is often a very personal one.

E-300 13:11 H300

How about other alternatives? Do the specifications of the Olympus E-300 and the Sony H300 place the cameras among the top in their class? Find out in the latest Best DSLR Camera and Best Superzoom Camera listings whether the two cameras rank among the cream of the crop.

In any case, while the comparison of technical specifications can provide a useful overview of the capabilities of different cameras, it remains incomplete and does no justice, for example, to the way the E-300 or the H300 perform in practice. User reviews, such as those found at amazon, can sometimes inform about these issues, but such feedback is often incomplete, inconsistent, and biased.

Expert reviews

This is why expert reviews are important. The table below provides a synthesis of the camera assessments of some of the best known photo-gear review sites (amateurphotographer [AP], cameralabs [CL], digitalcameraworld [DCW], dpreview [DPR], ephotozine [EPZ], photographyblog [PB]). As can be seen, the professional reviewers agree in many cases on the quality of different cameras, but sometimes their assessments diverge, reinforcing the earlier point that a camera decision is often a very personal choice.

The above review scores should be interpreted with care, though. The assessments were made in relation to similar cameras of the same technological generation. Hence, a score should always be seen in the context of the camera's market launch date and its price, and rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. Also, please note that some of the review sites have changed their methodology and reporting over time.
