Sony A5100 vs A7 IV
The Sony Alpha A5100 and the Sony Alpha A7 IV are two digital cameras that were announced, respectively, in August 2014 and October 2021. Both the A5100 and the A7 IV are mirrorless interchangeable lens cameras that are based on an APS-C (A5100) and a full frame (A7 IV) sensor. The A5100 has a resolution of 24 megapixels, whereas the A7 IV provides 32.7 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 Sony Alpha A5100 and the Sony Alpha A7 IV? 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.
Body comparison
The side-by-side display below illustrates the physical size and weight of the Sony A5100 and the Sony A7 IV. The two cameras are presented according to their relative size. Three consecutive views from the front, the top, and the rear side are shown. All width, height and depth dimensions are rounded to the nearest millimeter.
The A5100 can be obtained in two different colors (black, white), while the A7 IV 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 A7 IV is considerably larger (81 percent) than the Sony A5100. Moreover, the A7 IV is substantially heavier (133 percent) than the A5100. It is noteworthy in this context that the A7 IV is splash and dust-proof, while the A5100 does not feature any corresponding weather-sealing.
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 Sony E-Mount Lens Catalog (A5100) and the Sony FE Lens Catalog (A7 IV). Mirrorless cameras, such as the two under consideration, have the additional advantage of having a short flange to focal plane distance, which makes it possible to mount many lenses from other systems onto the camera via adapters.
Concerning battery life, the A5100 gets 400 shots out of its Sony NP-FW50 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.

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 A5100 was launched at a markedly lower price (by 78 percent) than the A7 IV, which puts it into a different 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. Then, after the new model is out, very good deals can frequently be found on the pre-owned market.
Sensor comparison
The imaging sensor is at the core of digital cameras and its size is one of the main determining factors 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 Sony A5100 features an APS-C sensor and the Sony A7 IV a full frame sensor. The sensor area in the A7 IV is 134 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.5 and 1.0. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.
Technology-wise, the A7 IV uses a more advanced image processing engine (BIONZ XR) than the A5100 (BIONZ X), with benefits for noise reduction, color accuracy, and processing speed.
With 32.7MP, the A7 IV offers a higher resolution than the A5100 (24MP), but the A7 IV nevertheless has larger individual pixels (pixel pitch of 5.12μm versus 3.91μm for the A5100) due to its larger sensor. Moreover, the A7 IV is a much more recent model (by 7 years and 2 months) than the A5100, and its sensor will have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixel-units. 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 Sony A7 IV implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the A7 IV for good quality output (200 dots per inch) amounts to 35 x 23.4 inches or 89 x 59.3 cm, for very good quality (250 dpi) 28 x 18.7 inches or 71.2 x 47.5 cm, and for excellent quality (300 dpi) 23.4 x 15.6 inches or 59.3 x 39.6 cm. The corresponding values for the Sony A5100 are 30 x 20 inches or 76.2 x 50.8 cm for good quality, 24 x 16 inches or 61 x 40.6 cm for very good quality, and 20 x 13.3 inches or 50.8 x 33.9 cm for excellent quality prints.
The Sony Alpha A5100 has a native sensitivity range from ISO 100 to ISO 25600. 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.
In terms of underlying technology, the A5100 is build around a CMOS sensor, while the A7 IV uses a BSI-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.
Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. 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 A7 IV offers substantially better image quality than the A5100 (overall score 17 points higher). The advantage is based on 1.6 bits higher color depth, 2 EV in additional dynamic range, and 1.3 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.

Many modern cameras are not only capable of taking still images, but can also record movies. Both cameras under consideration are equipped with sensors that have a sufficiently high read-out speed for moving images, but the A7 IV provides a better video resolution than the A5100. It can shoot movie footage at 4K/60p, while the A5100 is limited to 1080/60p.
Feature comparison
Apart from body and sensor, cameras can and do differ across a range 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 A5100 relies on live view and the rear LCD for framing.

Note: *) Information refers to the mechanical shutter, unless the camera only has an electronic one. |
One difference between the cameras concerns the presence of an on-board flash. The A5100 has one, while the A7 IV does not. While the built-in flash of the A5100 is not very powerful, it can at times be useful as a fill-in light.
Both cameras have an articulated rear screen that can be turned to be front-facing. This feature will be particularly appreciated by vloggers and photographers who are interested in taking selfies.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, the A7 IV is one of those camera that have an additional 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 A5100 writes its imaging data to SDXC or Memory Stick PRO Duo 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 A5100 only has one slot. The A7 IV supports UHS-II cards (on both slots), while the A5100 can use UHS-I cards.
Connectivity comparison
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 Sony Alpha A5100 and Sony Alpha A7 IV and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the A7 IV has a headphone jack, which makes it possible to attach external headphones and monitor the quality of sound during the recording process. The A5100 lacks such a headphone port.
The A7 IV is a recent model that features in the current product line-up of Sony. In contrast, the A5100 has been discontinued (but can be found pre-owned on ebay). There has not been a direct replacement model for the A5100 from Sony. Further information on the features and operation of the A5100 and A7 IV can be found, respectively, in the Sony A5100 Manual (free pdf) or the online Sony A7 IV Manual.
Review summary
So how do things add up? Which of the two cameras – the Sony A5100 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.
Advantages of the Sony Alpha A5100:
- Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.

If the count of relative strengths (bullet points above) is taken as a measure, the A7 IV is the clear winner of the contest (26 : 7 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 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.
How about other alternatives? Do the specifications of the Sony A5100 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 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 A5100 or the A7 IV 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.

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 comparing ratings of very distinct cameras or ones that are far apart in terms of their release date have little meaning. Also, please note that some of the review sites have changed their methodology and reporting over time.
