Nikon D7500 vs Sony A3000
The Nikon D7500 and the Sony Alpha A3000 are two digital cameras that were announced, respectively, in April 2017 and August 2013. The D7500 is a DSLR, while the A3000 is a mirrorless interchangeable lens camera. Both cameras are equipped with an APS-C sensor. The Nikon has a resolution of 20.7 megapixels, whereas the Sony provides 19.8 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 Nikon D7500 and the Sony Alpha A3000? 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.
An illustration of the physical size and weight of the Nikon D7500 and the Sony A3000 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 measures are rounded to the nearest millimeter.
If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Sony A3000 is notably smaller (18 percent) than the Nikon D7500. Moreover, the A3000 is substantially lighter (43 percent) than the D7500. It is worth mentioning in this context that the D7500 is splash and dust resistant, while the A3000 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. Both cameras have similarly sized sensors, but DSLRs have a larger flange-to-focal plane distance than mirrorless cameras, which imposes contraints on the optical engineering process and generally leads to bigger and heavier lenses. You can compare the optics available for the two cameras in the Nikon Lens Catalog (D7500) and the Sony E-Mount Lens Catalog (A3000). Mirrorless cameras, such as the A3000, have moreover the advantage that they can use many lenses from other systems via adapters, as they have a relatively short flange to focal plane distance.
Concerning battery life, the D7500 gets 950 shots out of its EN-EL15a battery, while the A3000 can take 470 images on a single charge of its NP-FW50 power pack. The power pack in the A3000 can be charged via the USB port, which can be very convenient when travelling.

The price is, of course, an important factor in any camera decision. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The A3000 was launched at a markedly lower price (by 75 percent) than the D7500, 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.
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. 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.
Both cameras under consideration feature an APS-C sensor, but their sensors differ slightly in size. The sensor area in the A3000 is 3 percent smaller. They nevertheless have the same format factor of 1.5. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.
With 20.7MP, the D7500 offers a slightly higher resolution than the A3000 (19.8MP), but the D7500 has marginally smaller individual pixels (pixel pitch of 4.22μm versus 4.25μm for the A3000). However, the D7500 is a much more recent model (by 3 years and 7 months) than the A3000, and its sensor will have benefitted from technological advances during this time that enhance the light gathering capacity of its pixels. Coming back to sensor resolution, it should be mentioned that the D7500 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.
The Nikon D7500 has a native sensitivity range from ISO 100 to ISO 51200, which can be extended to ISO 50-164000. The corresponding ISO settings for the Sony Alpha A3000 are ISO 100 to ISO 16000 (no boost).
For many cameras, data on sensor performance has been reported by DXO Mark. 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"). Of the two cameras under review, the D7500 has a notably higher overall DXO score than the A3000 (overall score 8 points higher), which gives it an advantage in terms of imaging quality. This advantage is based on 0.6 bits higher color depth, 1.2 EV in additional dynamic range, and 0.5 stops in additional low light sensitivity. 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, but the D7500 provides a higher video resolution than the A3000. It can shoot video footage at 4K/30p, while the Sony is limited to 1080/60i.
Beyond body and sensor, cameras can and do differ across a range of features. For example, the A3000 has an electronic viewfinder (202k dots), while the D7500 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 viewfinders of both cameras offer the same field of view (100%), but the viewfinder of the D7500 has a higher magnification than the one of the A3000 (0.61x vs 0.47x), so that the size of the image transmitted appears closer to the size seen with the naked human eye. The table below summarizes some of the other core capabilities of the Nikon D7500 and Sony A3000 in connection with corresponding information for a sample of similar cameras.

One feature that is present on the D7500, but is missing on the A3000 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 Nikon D7500 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 D7500 writes its imaging data to SDXC cards, while the A3000 uses SDXC or Memory Stick PRO Duo cards. The D7500 supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the A3000 cannot take advantage of Ultra High Speed SD cards.
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 Nikon D7500 and Sony Alpha A3000 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the D7500 has a microphone port, which is missing on the A3000. Such an external microphone input can help to substantially improve the quality of audio recordings when a good external microphone is used.
The D7500 is a recent model that features in the current product line-up of Nikon. In contrast, the A3000 has been discontinued (but can be found pre-owned on eBay). There has not been a direct replacement model for the A3000 from Sony. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Nikon and Sony websites.
So what conclusions can be drawn? Is the Nikon D7500 better than the Sony A3000 or vice versa? Below is a summary of the relative strengths of each of the two contestants.
Advantages of the Nikon D7500:
- Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
- Better image quality: Scores markedly higher (8 points) in the DXO overall assessment.
- More dynamic range: Captures a larger spectrum of light and dark details (1.2 EV of extra DR).
- Better low-light sensitivity: Requires less light for good images (0.5 stops ISO advantage).
- Better video: Provides higher definition movie capture (4K/30p vs 1080/60i).
- Better sound: Can connect to an external microphone for higher quality sound recording.
- Better sound control: Has a headphone port that enables audio monitoring while recording.
- Brighter framing: Features an optical viewfinder for clear, lag-free composition.
- Larger viewfinder image: Features a viewfinder with a higher magnification (0.61x vs 0.47x).

Reasons to prefer the Sony Alpha A3000:
- Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
- More framing info: Has an electronic viewfinder that displays shooting data.
- More compact: Is smaller (128x91mm vs 136x104mm) and will fit more readily into a bag.
- Less heavy: Has a lower weight (by 309g or 43 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.
- More affordable: Was introduced into a lower priced category (75 percent cheaper at launch).
- More heavily discounted: Has been around for much longer (launched in August 2013).
If the count of relative strengths (bullet points above) is taken as a measure, the D7500 is the clear winner of the match-up (23 : 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 Nikon D7500 and the Sony A3000 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 the spec-sheets of cameras can offer a general idea of their imaging potential, it remains partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the D7500 or the A3000. 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 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 comparisons of ratings among very different cameras or across long time periods have little meaning. Also, please note that some of the review sites have changed their methodology and reporting over time.
