Canon 20D vs Samsung NX30

The Canon EOS 20D and the Samsung NX30 are two digital cameras that were announced, respectively, in August 2004 and January 2014. The 20D is a DSLR, while the NX30 is a mirrorless interchangeable lens camera. Both cameras are equipped with an APS-C sensor. The Canon has a resolution of 8.2 megapixels, whereas the Samsung provides 20 MP.

Below is an overview of the main specs of the two cameras as a starting point for the comparison.

Body comparison

An illustration of the physical size and weight of the Canon 20D and the Samsung NX30 is provided in the side-by-side display below. The two cameras are presented according to their relative size. Three consecutive perspectives from the front, the top, and the back are available. All width, height and depth dimensions are rounded to the nearest millimeter.

Size Canon 20D vs Samsung NX30
Compare 20D versus NX30 top
Comparison 20D or NX30 rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Samsung NX30 is notably smaller (20 percent) than the Canon 20D. Moreover, the NX30 is substantially lighter (51 percent) than the 20D. In this context, it is worth noting that neither the 20D nor the NX30 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. Hence, you might want to study and compare the specifications of available lenses in order to get the full picture of the size and weight of the two camera systems.

The power pack in the NX30 can be charged via the USB port, which can be very convenient when travelling.

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 retail prices at the time of the camera’s release place the model in the market relative to other models in the producer’s line-up and the competition. The NX30 was launched at a markedly lower price (by 33 percent) than the 20D, which puts it into a different market segment. 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. Then, after the new model is out, very good deals can frequently be found on the pre-owned market.

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.

Both cameras under consideration feature an APS-C sensor, but their sensors differ slightly in size. The sensor area in the NX30 is 9 percent bigger. As a result of these sensor size differences, the cameras have format factors, respectively, of 1.6 (20D) and 1.5. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

Canon 20D and Samsung NX30 sensor measures

With 20MP, the NX30 offers a higher resolution than the 20D (8.2MP), but the NX30 has smaller individual pixels (pixel pitch of 4.30μm versus 6.42μm for the 20D). Yet, the NX30 is a much more recent model (by 9 years and 4 months) than the 20D, and its sensor will have benefitted from technological advances during this time that enhance the light gathering capacity of its pixel-units. Coming back to sensor resolution, it should be mentioned that the NX30 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

The resolution advantage of the Samsung NX30 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the NX30 for good quality output (200 dots per inch) amounts to 27.4 x 18.2 inches or 69.5 x 46.3 cm, for very good quality (250 dpi) 21.9 x 14.6 inches or 55.6 x 37.1 cm, and for excellent quality (300 dpi) 18.2 x 12.2 inches or 46.3 x 30.9 cm. The corresponding values for the Canon 20D are 17.5 x 11.7 inches or 44.5 x 29.7 cm for good quality, 14 x 9.3 inches or 35.6 x 23.7 cm for very good quality, and 11.7 x 7.8 inches or 29.7 x 19.8 cm for excellent quality prints.

The NX30 has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.

The Canon EOS 20D has a native sensitivity range from ISO 100 to ISO 1600, which can be extended to ISO 100-3200. The corresponding ISO settings for the Samsung NX30 are ISO 100 to ISO 25600 (no boost).

Technology-wise, both cameras are equipped with CMOS (Complementary Metal–Oxide–Semiconductor) 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.

20D versus NX30 MP

For many cameras, data on sensor performance has been reported by DXO Mark. This service assesses and scores the color depth ("DXO Portrait"), dynamic range ("DXO Landscape"), and low-light sensitivity ("DXO Sports") of camera sensors, and also publishes an overall camera score. Of the two cameras under consideration, the NX30 offers substantially better image quality than the 20D (overall score 14 points higher). The advantage is based on 1.6 bits higher color depth, 1.4 EV in additional dynamic range, and 0.5 stops in additional low light sensitivity. The adjacent table reports on the physical sensor characteristics and the outcomes of the DXO sensor quality tests for a sample of comparator-cameras.

Feature comparison

Beyond body and sensor, cameras can and do differ across a range of features. For example, the NX30 has an electronic viewfinder (2359k dots), while the 20D has an optical one. Both systems have their advantages, with the electronic viewfinder making it possible to project supplementary shooting information into the framing view, whereas the optical viewfinder offers lag-free viewing and a very clear framing image. The viewfinder in the NX30 offers a wider field of view (100%) than the one in the 20D (95%), so that a larger proportion of the captured image is visible in the finder. In addition, the viewfinder of the NX30 has a higher magnification (0.64x vs 0.56x), so that the size of the image transmitted appears closer to the size seen with the naked human eye. The following table reports on some other key feature differences and similarities of the Canon 20D, the Samsung NX30, and comparable cameras.

One feature that is present on the 20D, but is missing on the NX30 is a top-level LCD. While being, of course, smaller than the rear screen, the control panel conveys some of the essential shooting information and can be convenient for quick and easy settings verification.

The NX30 has an articulated screen that can be turned to be front-facing. This characteristic will be appreciated by vloggers and photographers who are interested in taking selfies. In contrast, the 20D does not have a selfie-screen.

The Samsung NX30 has an intervalometer built-in. This enables the photographer to capture time lapse sequences, such as flower blooming, a sunset or moon rise, without purchasing an external camera trigger and related software.

The 20D writes its imaging data to Compact Flash cards, while the NX30 uses SDXC cards.

It is notable that the NX30 offers wifi support, which can be a very convenient means to transfer image data to an off-camera location. In contrast, the 20D does not provide wifi capability.

Studio photographers will appreciate that the Canon 20D (unlike the NX30) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

Both the 20D and the NX30 have been discontinued, but can regularly be found used on ebay. The 20D was replaced by the Canon 30D, while the NX30 does not have a direct successor. Further information on the features and operation of the 20D and NX30 can be found, respectively, in the Canon 20D Manual (free pdf) or the online Samsung NX30 Manual.

Review summary

So what conclusions can be drawn? Which of the two cameras – the Canon 20D or the Samsung NX30 – has the upper hand? Is one clearly better than the other? A synthesis of the relative strong points of each of the models is listed below.

ilogo

Arguments in favor of the Canon EOS 20D:

  • Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
  • Brighter framing: Features an optical viewfinder for clear, lag-free composition.
  • Easier setting verification: Features an LCD display on top to control shooting parameters.

  • Better studio light control: Has a PC Sync socket to connect to professional strobe lights.
  • More heavily discounted: Has been available for much longer (launched in August 2004).

ilogo

Reasons to prefer the Samsung NX30:

  • More detail: Has more megapixels (20 vs 8.2MP), which boosts linear resolution by 56%.
  • Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
  • Better image quality: Scores substantially higher (14 points) in the DXO overall evaluation.
  • Richer colors: Generates noticeably more natural colors (1.6 bits more color depth).
  • More dynamic range: Captures a broader range of light and dark details (1.4 EV of extra DR).
  • Better low-light sensitivity: Can shoot in dim conditions (0.5 stops ISO advantage).
  • Broader imaging potential: Can capture not only stills but also 1080/60p video.
  • Better live-view autofocus: Features on-sensor phase-detection for more confident autofocus.
  • More framing info: Has an electronic viewfinder that displays shooting data.
  • More complete view: Has a viewfinder with a larger field of view (100% vs 95%).
  • Larger viewfinder image: Features a viewfinder with a higher magnification (0.64x vs 0.56x).
  • 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 (1036k vs 118k dots).
  • More flexible LCD: Has a swivel screen for odd-angle shots in portrait or landscape orientation.
  • Fewer buttons to press: Has a touchscreen to facilitate handling and shooting adjustments.
  • More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
  • Faster burst: Shoots at higher frequency (9 vs 5 flaps/sec) to capture the decisive moment.
  • Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
  • More compact: Is smaller (127x96mm vs 144x106mm) and will fit more readily into a bag.
  • Less heavy: Has a lower weight (by 395g or 51 percent) and is thus easier to take along.
  • Easier travel charging: Can be conveniently charged via its USB port.
  • More legacy lens friendly: Can use many non-native lenses via adapters.
  • Faster data transfer: Supports a more advanced USB protocol (2.0 vs 1.1).
  • Easier file upload: Has wifi built in for automatic backup or image transfer to the web.
  • Easier device pairing: Supports NFC for fast wireless image transfer over short distances.
  • More affordable: Was introduced into a lower priced category (33 percent cheaper at launch).
  • More modern: Reflects 9 years and 4 months of technical progress since the 20D launch.

If the number of relative strengths (bullet points above) is taken as a guide, the NX30 is the clear winner of the contest (27 : 6 points). However, the relevance of individual strengths will vary across photographers, so that you might want to apply your own weighing scheme to the summary points when reflecting and deciding on a new camera. A professional wedding photographer will view the differences between cameras in a way that diverges from the perspective of a travel photog, and a person interested in cityscapes has distinct needs from a macro shooter. Hence, the decision which camera is best and worth buying is often a very personal one.

20D 06:27 NX30

How about other alternatives? Do the specifications of the Canon 20D and the Samsung NX30 place the cameras among the top in their class? Find out in the latest Best DSLR Camera and Best Mirrorless Interchangeable Lens 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 says little about, for example, the shooting experience and imaging performance of the 20D and the NX30 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.

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 review scores listed above should be treated 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 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.
