Body comparison

The physical size and weight of the Sigma fp L and the Sony A7 IV are illustrated 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 measures are rounded to the nearest millimeter.

Size Sigma fp L vs Sony A7 IV
Compare fp L versus A7 IV top
Comparison fp L or A7 IV rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Sony A7 IV is considerably larger (59 percent) than the Sigma fp L. Moreover, the A7 IV is substantially heavier (54 percent) than the fp L. 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 L gets 240 shots out of its Sigma BP-51 battery, while the A7 IV can take 580 images on a single charge of its Sony NP-FZ100 power pack. The battery packs of both cameras can be charged via USB, 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. In case you want to display and compare another camera duo, you can use the CAM-parator app to select your camera combination among a large number of options.

Any camera decision will naturally be influenced heavily by the price. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The two cameras under review were launched at the same price and fall into the same 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. 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 tend to be more expensive and lead to bigger and heavier cameras and lenses.

Both cameras under consideration feature a full frame sensor, but their sensors differ slightly in size. The sensor area in the A7 IV is 1 percent smaller. They nevertheless have the same format factor of 1.0. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

Sigma fp L and Sony A7 IV sensor measures

With 60.2MP, the fp L offers a higher resolution than the A7 IV (32.7MP), but the fp L has smaller individual pixels (pixel pitch of 3.79μm versus 5.12μm for the A7 IV). Moreover, the A7 IV is a somewhat more recent model (by 6 months) than the fp L, and its sensor might 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 A7 IV has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

The resolution advantage of the Sigma fp L implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the fp L for good quality output (200 dots per inch) amounts to 47.6 x 31.6 inches or 120.9 x 80.4 cm, for very good quality (250 dpi) 38.1 x 25.3 inches or 96.7 x 64.3 cm, and for excellent quality (300 dpi) 31.7 x 21.1 inches or 80.6 x 53.6 cm. The corresponding values for the Sony A7 IV are 35 x 23.4 inches or 89 x 59.3 cm for good quality, 28 x 18.7 inches or 71.2 x 47.5 cm for very good quality, and 23.4 x 15.6 inches or 59.3 x 39.6 cm for excellent quality prints.

The A7 IV has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.

The Sigma fp L 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 A7 IV are ISO 100 to ISO 51200, with the possibility to increase the ISO range to 50-204800.

Technology-wise, both cameras are equipped with BSI-CMOS (Backside Illuminated 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.

Feature comparison

Apart from body and sensor, cameras can and do differ across a variety of features. For example, the A7 IV has an electronic viewfinder (3686k dots), which can be very helpful when shooting in bright sunlight. In contrast, the fp L relies on live view and the rear LCD for framing. That said, the fp L can be equipped with an optional viewfinder – the EVF-11. The table below summarizes some of the other core capabilities of the Sigma fp L and Sony A7 IV in connection with corresponding information for a sample of similar cameras.

One feature that differentiates the A7 IV and the fp L is in-body image stabilization (IBIS). The A7 IV reduces the risk of handshake-induced blur with all attached lenses, while the fp L offers no blur reduction with lenses that themselves do not provide optical image stabilization.

The A7 IV 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 fp L does not have a selfie-screen.

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 L 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 L writes its imaging data to SDXC cards, while the A7 IV uses CFexpress (type A) or SDXC cards. The A7 IV features dual card slots, which can be very useful in case a memory card fails. In contrast, the fp L only has one slot. Moreover, both cameras support UHS-II cards (Ultra High Speed data transfer of up to 312 MB/s).

Review summary

So what is the bottom line? Which of the two cameras – the Sigma fp L or the Sony A7 IV – 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

Reasons to prefer the Sigma fp L:

  • More detail: Offers more megapixels (60.2 vs 32.7MP) with a 36% higher linear resolution.
  • Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
  • 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 1037k dots).
  • Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
  • More compact: Is smaller (113x70mm vs 131x96mm) and thus needs less room in the bag.
  • Less heavy: Is lighter (by 232g or 35 percent) and hence easier to carry around.
  • More heavily discounted: Has been on the market for longer (launched in March 2021).

ilogo

Advantages of the Sony Alpha A7 IV:

  • Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
  • Better video: Provides higher movie framerates (4K/60p versus 4K/30p).
  • 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 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 (580 versus 240) out of a single battery charge.
  • Sharper images: Has stabilization technology built-in to reduce the impact of hand-shake.
  • More solid recording: Has a full-sized HDMI port for a sturdy connection to an external recorder.
  • Easier wireless transfer: Supports Bluetooth for image sharing without cables.
  • Greater peace of mind: Features a second card slot as a backup in case of memory card failure.
  • More modern: Was introduced somewhat (6 months) more recently.

If the count of relative strengths (bullet points above) is taken as a measure, the A7 IV is the clear winner of the contest (12 : 8 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 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.

fp L 08:12 A7 IV

How about other alternatives? Do the specifications of the Sigma fp L and the Sony A7 IV 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 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 fp L and the A7 IV 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.

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 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 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.
