Going beyond this snapshot of core features and characteristics, what are the differences between the Leica TL2 and the Nikon D3400? 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 physical size and weight of the Leica TL2 and the Nikon D3400 are illustrated in the side-by-side display below. 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 measures are rounded to the nearest millimeter.

The TL2 can be obtained in two different colors (black, silver), while the D3400 is also available in two color-versions, but different ones (black, red).

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Nikon D3400 is notably larger (31 percent) than the Leica TL2. Moreover, the D3400 is markedly heavier (12 percent) than the TL2. In this context, it is worth noting that neither the TL2 nor the D3400 are weather-sealed.

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 TL2 gets 250 shots out of its Leica BP-DC13 battery, while the D3400 can take 1200 images on a single charge of its Nikon EN-EL14a power pack. The power pack in the TL2 can be charged via the USB port, so that it is not always necessary to take the battery charger along when travelling.

The adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives.

The price is, of course, an important factor in any camera decision. The manufacturer’s suggested retail prices give an idea on the placement of the camera in the maker’s lineup and the broader market. The D3400 was launched at a markedly lower price (by 74 percent) than the TL2, 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. 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 imaging sensor is a crucial determinant 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. Moreover, a large sensor camera will give the photographer more control over depth-of-field in the image and, thus, the ability to better isolate a subject from the 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 an APS-C sensor, but their sensors differ slightly in size. The sensor area in the D3400 is 1 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 24.1MP, the TL2 offers a slightly higher resolution than the D3400 (24MP), but the TL2 nevertheless has marginally larger individual pixels (pixel pitch of 3.92μm versus 3.91μm for the D3400) due to its larger sensor. Moreover, the TL2 is a somewhat more recent model (by 10 months) than the D3400, 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 neither of the two cameras has an anti-alias filter installed, so they are able to capture all the detail the sensor resolves.

The Leica TL2 has a native sensitivity range from ISO 100 to ISO 50000. The corresponding ISO settings for the Nikon D3400 are ISO 100 to ISO 25600 (no boost).

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

Consistent information on actual sensor performance is available from DXO Mark for many cameras. 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"). 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 are equipped with sensors that have a sufficiently high read-out speed for moving images, but the TL2 provides a higher video resolution than the D3400. It can shoot video footage at 4K/30p, while the Nikon is limited to 1080/60p.

Feature comparison

Beyond body and sensor, cameras can and do differ across a range of features. For example, the D3400 has an optical viewfinder, which can be very useful when shooting in bright sunlight. In contrast, the TL2 relies on live view and the rear LCD for framing. That said, the TL2 can be equipped with an optional viewfinder – the Visoflex (Typ 020). The following table reports on some other key feature differences and similarities of the Leica TL2, the Nikon D3400, and comparable cameras.

One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The TL2 has a touchscreen, while the D3400 has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.

Concerning the storage of imaging data, both the TL2 and the D3400 write their files to SDXC cards. The TL2 supports UHS-II cards (Ultra High Speed data transfer of up to 312 MB/s), while the D3400 can use UHS-I cards (up to 104 MB/s).

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 Leica TL2 and Nikon D3400 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the TL2 offers wifi support, while the D3400 does not. Wifi can be a very convenient means to transfer image data to an off-camera location.

Both the TL2 and the D3400 have been discontinued, but can regularly be found used on ebay. The D3400 was replaced by the Nikon D3500, while the TL2 does not have a direct successor. Further information on the features and operation of the TL2 and D3400 can be found, respectively, in the Leica TL2 Manual (free pdf) or the online Nikon D3400 Manual.

Review summary

So what is the bottom line? Is the Leica TL2 better than the Nikon D3400 or vice versa? A synthesis of the relative strong points of each of the models is listed below.

Arguments in favor of the Leica TL2:

• Better video: Provides higher definition movie capture (4K/30p vs 1080/60p).
• Larger screen: Has a bigger rear LCD (3.7" vs 3.0") for image review and settings control.
• More detailed LCD: Has a higher resolution rear screen (1230k vs 921k dots).
• Fewer buttons to press: Is equipped with a touch-sensitive rear screen to facilitate handling.
• Faster burst: Shoots at higher frequency (7 vs 5 flaps/sec) to capture the decisive moment.
• More compact: Is smaller (134x69mm vs 124x98mm) and thus needs less room in the bag.
• Less heavy: Is lighter (by 46g or 10 percent) and hence easier to carry around.
• Easier travel charging: Can be conveniently charged via its USB port.
• More legacy lens friendly: Can take a broad range of non-native lenses via adapters.
• Faster data transfer: Supports a more advanced USB protocol (3.0 vs 2.0).
• Easier file upload: Has wifi built in for automatic backup or image transfer to the web.
• Faster buffer clearing: Supports a more advanced SD data transfer standard (UHS-II vs UHS-I).
• More prestigious: Has the Leica luxury appeal, which ensures a high resale price.
• More modern: Is somewhat more recent (announced 10 months after the D3400).

Reasons to prefer the Nikon D3400:

• Easier framing: Has an optical viewfinder for image composition and settings control.
• Longer lasting: Gets more shots (1200 versus 250) out of a single battery charge.
• Easier fill-in: Has a small integrated flash to brighten shadows of backlit subjects.
• Easier wireless transfer: Supports Bluetooth for image sharing without cables.
• More affordable: Was introduced into a lower priced category (74 percent cheaper at launch).
• More heavily discounted: Has been on the market for longer (launched in August 2016).

If the count of individual advantages (bullet points above) is taken as a guide, the TL2 is the clear winner of the match-up (14 : 6 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 Leica TL2 and the Nikon D3400 place the cameras among the top in their class? Find out in the latest Best Mirrorless Interchangeable Lens Camera and Best DSLR 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 says little about, for example, the shooting experience and imaging performance of the TL2 and the D3400 in practical situations. 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 hands-on reviews by experts 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], 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.

Note: (+ +) highly recommended; (+) recommended; (o) reviewed; (..) not available.

Care should be taken when interpreting the review scores above, though. The ratings were established in reference to similarly priced cameras that were available in the market at the time of the review. Thus, a score needs to be put into the context of the launch date and the launch price 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, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
