Fujifilm X-M1 vs Olympus E-620
The Fujifilm X-M1 and the Olympus E-620 are two digital cameras that were revealed to the public, respectively, in June 2013 and February 2009. The X-M1 is a mirrorless interchangeable lens camera, while the E-620 is a DSLR. The cameras are based on an APS-C (X-M1) and a Four Thirds (E-620) sensor. The Fujifilm has a resolution of 16 megapixels, whereas the Olympus provides 12.2 MP.
Below is an overview of the main specs of the two cameras as a starting point for the comparison.
Going beyond this snapshot of core features and characteristics, what are the differences between the Fujifilm X-M1 and the Olympus E-620? Which one should you buy? Read on to find out how these two cameras compare with respect to their body size, their imaging sensors, their shooting features, their input-output connections, and their reception by expert reviewers.
The side-by-side display below illustrates the physical size and weight of the Fujifilm X-M1 and the Olympus E-620. 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.
The X-M1 can be obtained in three different colors (black, silver, brown), while the E-620 is only available in black.
If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Olympus E-620 is considerably larger (56 percent) than the Fujifilm X-M1. Moreover, the E-620 is substantially heavier (58 percent) than the X-M1. In this context, it is worth noting that neither the X-M1 nor the E-620 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. A larger imaging sensor will tend to go along with bigger and heavier lenses, although exceptions exist. You can compare the optics available for the two cameras in the Fujinon X Lens Catalog (X-M1) and the Four Thirds Lens Catalog (E-620). Mirrorless cameras, such as the Fujifilm X-M1, have moreover the advantage that they have a relatively short flange to focal plane distance and can thus use many lenses from other systems via adapters.
The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators. If you would like to visualize and compare a different camera combination, you can navigate to the CAM-parator app and make your selection from a broad list of cameras there.

Any camera decision will naturally be influenced heavily by the price. The manufacturer’s suggested retail prices give an idea on the placement of the camera in the maker’s lineup and the broader market. The two cameras under review were launched at the same price and fall into the same market segment. 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.
The imaging sensor is at the core of digital cameras and its size is one of the main determining factors of image quality. All other things equal, a large sensor will have larger individual pixel-units that offer better low-light sensitivity, wider dynamic range, and richer color-depth than smaller pixels in a sensor of the same technological generation. Moreover, a large sensor camera will give the photographer more control over depth-of-field in the image and, thus, the ability to better isolate a subject from the background. On the downside, larger sensors are more costly to manufacture and tend to lead to bigger and heavier cameras and lenses.
Of the two cameras under consideration, the Fujifilm X-M1 features an APS-C sensor and the Olympus E-620 a Four Thirds sensor. The sensor area in the E-620 is 39 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.5 and 2.0. The sensor in the X-M1 has a native 3:2 aspect ratio, while the one in the E-620 offers a 4:3 aspect.
With 16MP, the X-M1 offers a higher resolution than the E-620 (12.2MP), but the X-M1 nevertheless has larger individual pixels (pixel pitch of 4.80μm versus 4.29μm for the E-620) due to its larger sensor. Moreover, the X-M1 is a much more recent model (by 4 years and 4 months) than the E-620, and its sensor will have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixels. Coming back to sensor resolution, it should be mentioned that the X-M1 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.
The resolution advantage of the Fujifilm X-M1 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the X-M1 for good quality output (200 dots per inch) amounts to 24.5 x 16.3 inches or 62.2 x 41.5 cm, for very good quality (250 dpi) 19.6 x 13.1 inches or 49.7 x 33.2 cm, and for excellent quality (300 dpi) 16.3 x 10.9 inches or 41.5 x 27.6 cm. The corresponding values for the Olympus E-620 are 20.2 x 15.1 inches or 51.2 x 38.4 cm for good quality, 16.1 x 12.1 inches or 41 x 30.7 cm for very good quality, and 13.4 x 10.1 inches or 34.1 x 25.6 cm for excellent quality prints.
The Fujifilm X-M1 has a native sensitivity range from ISO 200 to ISO 6400, which can be extended to ISO 100-25600. The corresponding ISO settings for the Olympus E-620 are ISO 100 to ISO 3200 (no boost).
Technology-wise, both cameras are equipped with CMOS (Complementary Metal–Oxide–Semiconductor) sensors. The X-M1 uses Fujifilm's X-Trans layout of photosites, while the E-620 employs the more common Bayer array.
Consistent information on actual sensor performance is available from DXO Mark for many cameras. This service determines an overall sensor rating, as well as sub-scores for low-light sensitivity ("DXO Sports"), dynamic range ("DXO Landscape"), and color depth ("DXO Portrait"). The table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar cameras.

Many modern cameras are not only capable of taking still images, but also of capturing video footage. The X-M1 indeed provides movie recording capabilities, while the E-620 does not. The highest resolution format that the X-M1 can use is 1080/30p.
Apart from body and sensor, cameras can and do differ across a range of features. For example, the E-620 has an optical viewfinder, which can be very useful when shooting in bright sunlight. In contrast, the X-M1 relies on live view and the rear LCD for framing. The table below summarizes some of the other core capabilities of the Fujifilm X-M1 and Olympus E-620 in connection with corresponding information for a sample of similar cameras.

One feature that differentiates the E-620 and the X-M1 is in-body image stabilization (IBIS). The E-620 reduces the risk of handshake-induced blur with all attached lenses, while the X-M1 offers no blur reduction with lenses that themselves do not provide optical image stabilization.The E-620 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 X-M1 does not have a selfie-screen.
The X-M1 writes its imaging data to SDXC cards, while the E-620 uses Compact Flash or xD Picture cards. The E-620 features dual card slots, which can be very useful in case a memory card fails. In contrast, the X-M1 only has one slot.
For some imaging applications, the extent to which a camera can communicate with its environment can be an important aspect in the camera decision process. The table below provides an overview of the connectivity of the Fujifilm X-M1 and Olympus E-620 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the X-M1 offers wifi support, while the E-620 does not. Wifi can be a very convenient means to transfer image data to an off-camera location.
Both the X-M1 and the E-620 have been discontinued, but can regularly be found used on ebay. The E-620 was replaced by the Olympus E-600, while the X-M1 does not have a direct successor. Further information on the features and operation of the X-M1 and E-620 can be found, respectively, in the Fujifilm X-M1 Manual (free pdf) or the online Olympus E-620 Manual.
So what is the bottom line? Which of the two cameras – the Fujifilm X-M1 or the Olympus E-620 – 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.
Advantages of the Fujifilm X-M1:
- More detail: Offers more megapixels (16 vs 12.2MP) with a 17% higher linear resolution.
- Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
- Better image quality: Features a larger and more technologically advanced imaging sensor.
- Richer colors: The sensor size advantage translates into images with better, more accurate colors.
- More dynamic range: Larger sensor captures a wider spectrum of light and dark details.
- Better low-light sensitivity: Larger sensor produces good images even in poorly lit environments.
- Broader imaging potential: Can record not only still images but also 1080/30p movies.
- Larger screen: Has a bigger rear LCD (3.0" vs 2.7") for image review and settings control.
- More detailed LCD: Has a higher resolution rear screen (920k vs 230k dots).
- Faster burst: Shoots at higher frequency (5.6 vs 4 flaps/sec) to capture the decisive moment.
- More compact: Is smaller (117x67mm vs 130x94mm) and thus needs less room in the bag.
- Less heavy: Is lighter (by 191g or 37 percent) and hence easier to carry around.
- More legacy lens friendly: Can take a broad range of non-native lenses via adapters.
- Easier file upload: Has wifi built in for automatic backup or image transfer to the web.
- More modern: Reflects 4 years and 4 months of technical progress since the E-620 launch.
Reasons to prefer the Olympus E-620:
- Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
- Easier framing: Has an optical viewfinder for image composition and settings control.
- More flexible LCD: Has a swivel screen for odd-angle shots in portrait or landscape orientation.
- More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
- Longer lasting: Gets more shots (500 versus 350) out of a single battery charge.
- Sharper images: Has stabilization technology built-in to reduce the impact of hand-shake.
- Greater peace of mind: Features a second card slot as a backup in case of memory card failure.
- More heavily discounted: Has been around for much longer (launched in February 2009).
If the number of relative strengths (bullet points above) is taken as a guide, the X-M1 is the clear winner of the match-up (15 : 8 points). However, the relative importance of the various individual camera aspects will vary according to personal preferences and needs, so that you might like to apply corresponding weights to the particular features before making a decision 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.
How about other alternatives? Do the specifications of the Fujifilm X-M1 and the Olympus E-620 place the cameras among the top in their class? Find out in the latest Best Mirrorless Interchangeable Lens Camera and Best DSLR Camera listings whether the two cameras rank among the cream of the crop.
In any case, while the comparison of the spec-sheets of cameras can offer a general idea of their imaging potential, it says little about, for example, the shooting experience and imaging performance of the X-M1 and the E-620 in practical situations. At times, user reviews, such as those published at amazon, address these issues in a useful manner, but such feedback is on many occasions incomplete, inconsistent, and unreliable.
This is where reviews by experts come in. The adjacent summary-table relays the overall verdicts of several of the most popular camera 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.

Care should be taken when interpreting the review scores above, though. The ratings are only valid when referring to cameras in the same category and of the same age. A score, therefore, has to be seen in close connection to the price and market introduction time 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.
