Nikon D7000 vs Panasonic TZ90
The Nikon D7000 and the Panasonic Lumix DC-TZ90 (labelled Panasonic ZS70 in some countries) are two digital cameras that were announced, respectively, in September 2010 and April 2017. The D7000 is a DSLR, while the TZ90 is a fixed lens compact. The cameras are based on an APS-C (D7000) and a 1/2.3-inch (TZ90) sensor. The Nikon has a resolution of 16.1 megapixels, whereas the Panasonic provides 20.2 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 Nikon D7000 and the Panasonic Lumix DC-TZ90? 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 Nikon D7000 and the Panasonic TZ90. 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 dimensions are rounded to the nearest millimeter.
The TZ90 can be obtained in two different colors (black, silver), while the D7000 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 Panasonic TZ90 is considerably smaller (46 percent) than the Nikon D7000. It is worth mentioning in this context that the D7000 is splash and dust resistant, while the TZ90 does not feature any corresponding weather-sealing.
The above size and weight comparisons are to some extent incomplete and possibly misleading, as the TZ90 has a lens built in, whereas the D7000 is an interchangeable lens camera that requires a separate lens. Attaching the latter will add extra weight and bulk to the setup. You can compare the optics available for the D7000 and their specifications in the Nikon Lens Catalog.
Concerning battery life, the D7000 gets 1050 shots out of its EN-EL15 battery, while the TZ90 can take 380 images on a single charge of its DMW-BLG10 power pack. The power pack in the TZ90 can be charged via the USB port, which can be very convenient when travelling.
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 obviously take relative prices into account. 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 TZ90 was launched at a lower price than the D7000, despite having a lens built in. 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. 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 associated with larger, more expensive camera bodies and lenses.
Of the two cameras under consideration, the Nikon D7000 features an APS-C sensor and the Panasonic TZ90 a 1/2.3-inch sensor. The sensor area in the TZ90 is 92 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.5 and 5.6. The sensor in the D7000 has a native 3:2 aspect ratio, while the one in the TZ90 offers a 4:3 aspect.
Despite having a smaller sensor, the TZ90 offers a higher resolution of 20.2 megapixels, compared with 16.1 MP of the D7000. This megapixels advantage comes at the cost of a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 1.18μm versus 4.80μm for the D7000). However, it should be noted that the TZ90 is much more recent (by 6 years and 7 months) than the D7000, and its sensor will have benefitted from technological advances during this time that make it possible to gather light more efficiently. Coming back to sensor resolution, it should be mentioned that the TZ90 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.
The resolution advantage of the Panasonic TZ90 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the TZ90 for good quality output (200 dots per inch) amounts to 25.9 x 19.4 inches or 65.8 x 49.4 cm, for very good quality (250 dpi) 20.7 x 15.6 inches or 52.7 x 39.5 cm, and for excellent quality (300 dpi) 17.3 x 13 inches or 43.9 x 32.9 cm. The corresponding values for the Nikon D7000 are 24.6 x 16.3 inches or 62.6 x 41.5 cm for good quality, 19.7 x 13.1 inches or 50.1 x 33.2 cm for very good quality, and 16.4 x 10.9 inches or 41.7 x 27.6 cm for excellent quality prints.
The Nikon D7000 has a native sensitivity range from ISO 100 to ISO 6400, which can be extended to ISO 100-25600. The corresponding ISO settings for the Panasonic Lumix DC-TZ90 are ISO 80 to ISO 3200, with the possibility to increase the ISO range to 80-6400.
Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. 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 D7000 provides substantially higher image quality than the TZ90, with an overall score that is 44 points higher. This advantage is based on 4.4 bits higher color depth, 3.3 EV in additional dynamic range, and 3.5 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 have a sensor with sufficiently fast read-out times for moving pictures, but the TZ90 provides a better video resolution than the D7000. It can shoot movie footage at 4K/30p, while the Nikon is limited to 10800/24p.
Apart from body and sensor, cameras can and do differ across a range of features. For example, the TZ90 has an electronic viewfinder (1166k dots), while the D7000 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 D7000 has a higher magnification than the one of the TZ90 (0.63x vs 0.46x), so that the size of the image transmitted appears closer to the size seen with the naked human eye. The following table reports on some other key feature differences and similarities of the Nikon D7000, the Panasonic TZ90, and comparable cameras.
One feature that is present on the D7000, but is missing on the TZ90 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 TZ90 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 D7000 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, the TZ90 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 Nikon D7000 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.
Concerning the storage of imaging data, both the D7000 and the TZ90 write their files to SDXC cards. The D7000 features dual card slots, which can be very useful in case a memory card fails. In contrast, the TZ90 only has one slot. The TZ90 supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the D7000 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 D7000 and Panasonic Lumix DC-TZ90 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the D7000 has a hotshoe, while the TZ90 does not. This socket makes it possible to easily attach optional accessories, such as an external flash gun.
Both the D7000 and the TZ90 have been discontinued, but can regularly be found used on eBay. The D7000 was replaced by the Nikon D7100, while the TZ90 was followed by the Panasonic TZ95. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Nikon and Panasonic websites.
So how do things add up? Is the Nikon D7000 better than the Panasonic TZ90 or vice versa? The listing below highlights the relative strengths of the two models.

If the count of individual advantages (bullet points above) is taken as a guide, the TZ90 emerges as the winner of the match-up (19 : 17 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 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.

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 D7000 and the TZ90 in practical situations. User reviews that are available, for instance, at amazon can sometimes shed light on these issues, but such feedback is all too often partial, inconsistent, and inaccurate.
This is why expert reviews are important. The following table reports the overall ratings of the cameras as published by some of the major camera review sites (amateurphotographer [AP], cameralabs [CL], 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.
