Sigma fp vs Sony A6300
The Sigma fp and the Sony Alpha A6300 are two digital cameras that were announced, respectively, in July 2019 and February 2016. Both the fp and the A6300 are mirrorless interchangeable lens cameras that are based on a full frame (fp) and an APS-C (A6300) sensor. Both cameras offer a resolution of 24 megapixels.
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 Sigma fp and the Sony Alpha A6300? 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 Sigma fp and the Sony A6300. 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 A6300 can be obtained in two different colors (black, silver), while the fp 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 Sony A6300 is somewhat larger (2 percent) than the Sigma fp. However, the A6300 is slightly lighter (4 percent) than the fp. In this context, it is worth noting that both cameras are splash and dust-proof and can, hence, be used in inclement weather conditions or harsh environments.
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.
Concerning battery life, the fp gets 280 shots out of its BP-51 battery, while the A6300 can take 400 images on a single charge of its NP-FW50 power pack. The battery packs of both cameras can be charged via USB, which can be very convenient when travelling.
The adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives. 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.

The price is, of course, an important factor in any camera decision. 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 A6300 was launched at a markedly lower price (by 47 percent) than the fp, 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.
The size of the sensor inside a digital camera is one of the key determinants of image quality. A large sensor will generally have larger individual pixels that offer better low-light sensitivity, provide wider dynamic range, and have richer color-depth than smaller pixels in a sensor of the same technological generation. Further, a large sensor camera will give the photographer additional creative options when using shallow depth-of-field to isolate a subject from its 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 Sigma fp features a full frame sensor and the Sony A6300 an APS-C sensor. The sensor area in the A6300 is 57 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.0 and 1.5. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.
Even though the fp has a larger sensor, both cameras offer the same resolution of 24 megapixels. This implies that the fp has a lower pixel density and larger individual pixels (with a pixel pitch of 5.98μm versus 3.91μm for the A6300), which gives it a potential advantage in terms of light gathering capacity. In addition, the fp is much more recent (by 3 years and 5 months) than the A6300, and its sensor will have benefitted from technological advances during this time. Coming back to sensor resolution, it should be mentioned that the fp has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.
The A6300 has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.
The Sigma fp has a native sensitivity range from ISO 100 to ISO 25600, which can be extended to ISO 6-102400. The corresponding ISO settings for the Sony Alpha A6300 are ISO 100 to ISO 25600, with the possibility to increase the ISO range to 100-51200.
In terms of underlying technology, the fp is build around a BSI-CMOS sensor, while the A6300 uses a CMOS imager. Both cameras use a Bayer filter for capturing RGB colors on a square grid of photosensors. This arrangement is found in most digital cameras.
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"). The following table provides an overview of the physical sensor characteristics, as well as the sensor quality measurements for a selection of comparators.

Many modern cameras cannot only take still pictures, but also record videos. Both cameras under consideration have a sensor with sufficiently fast read-out times for moving pictures, and both provide the same movie specifications (4K/30p).
Apart from body and sensor, cameras can and do differ across a variety of features. For example, the A6300 has an electronic viewfinder (2359k dots), which can be very helpful when shooting in bright sunlight. In contrast, the fp relies on live view and the rear LCD for framing. That said, the fp can be equipped with an optional viewfinder – the EVF-11. The following table reports on some other key feature differences and similarities of the Sigma fp, the Sony A6300, and comparable cameras.

|Notes: *) Information refers to the mechanical shutter, unless the camera only has an electronic one.|
One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The fp has a touchscreen, while the A6300 has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.
The reported shutter speed information refers to the use of the mechanical shutter. Yet, some cameras only have an electronic shutter, while others have an electronic shutter in addition to a mechanical one. In fact, both cameras under consideration feature an electronic shutter, which makes completely silent shooting possible. However, this mode is less suitable for photographing moving objects (risk of rolling shutter) or shooting under artificial light sources (risk of flickering).
The Sigma fp 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 fp writes its imaging data to SDXC cards, while the A6300 uses SDXC or Memory Stick PRO Duo cards. The fp supports UHS-II cards (Ultra High Speed data transfer of up to 312 MB/s), while the A6300 can use UHS-I cards (up to 104 MB/s).
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 Sigma fp and Sony Alpha A6300 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the A6300 offers wifi support, which can be a very convenient means to transfer image data to an off-camera location. In contrast, the fp does not provide wifi capability.
The fp is a recent model that features in the current product line-up of Sigma. In contrast, the A6300 has been discontinued (but can be found pre-owned on ebay). As a replacement in the same line of cameras, the A6300 was succeeded by the Sony A6500. Further information on the features and operation of the fp and A6300 can be found, respectively, in the Sigma fp Manual (free pdf) or the online Sony A6300 Manual.
So what is the bottom line? Is the Sigma fp better than the Sony A6300 or vice versa? Below is a summary of the relative strengths of each of the two contestants.
Arguments in favor of the Sigma fp:
- 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.
- Larger screen: Has a bigger rear LCD (3.2" vs 3.0") for image review and settings control.
- More detailed LCD: Has a higher resolution rear screen (2100k vs 922k dots).
- Fewer buttons to press: Is equipped with a touch-sensitive rear screen to facilitate handling.
- Faster shutter: Has higher mechanical shutter speed (1/8000s vs 1/4000s) to freeze action.
- Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
- Faster data transfer: Supports a more advanced USB protocol (3.1 vs 2.0).
- Faster buffer clearing: Supports a more advanced SD data transfer standard (UHS-II vs UHS-I).
- More modern: Reflects 3 years and 5 months of technical progress since the A6300 launch.
Reasons to prefer the Sony Alpha A6300:
- Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
- Better live-view autofocus: Features on-sensor phase-detection for more confident autofocus.
- Easier framing: Has an electronic viewfinder for image composition and settings control.
- More flexible LCD: Has a tilting screen for odd-angle shots in landscape orientation.
- Longer lasting: Gets more shots (400 versus 280) out of a single battery charge.
- Easier fill-in: Has a small integrated flash to brighten shadows of backlit subjects.
- 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 heavily discounted: Has been around for much longer (launched in February 2016).
If the number of relative strengths (bullet points above) is taken as a guide, the fp emerges as the winner of the contest (13 : 10 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 wildlife photographer will view the differences between cameras in a way that diverges from the perspective of a family photog, and a person interested in architecture has distinct needs from a sports 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 Sigma fp and the Sony A6300 place the cameras among the top in their class? Find out in the latest Best Mirrorless Interchangeable Lens Camera listing whether the two cameras rank among the cream of the crop.
In any case, while the specs-based evaluation of cameras can be instructive in revealing their potential as photographic tools, it remains incomplete and does no justice, for example, to the way the fp or the A6300 perform in practice. 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 why expert reviews are important. 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. 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. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
