Body comparison

An illustration of the physical size and weight of the Leica D-LUX Typ 109 and the Sony A7 IV is provided 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 D-LUX Typ 109 can be obtained in two different colors (black, grey), while the A7 IV is only available in black.

Comparison D-LUX Typ 109 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 (61 percent) than the Leica D-LUX Typ 109. It is noteworthy in this context that the A7 IV is splash and dust-proof, while the D-LUX Typ 109 does not feature any corresponding weather-sealing.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the D-LUX Typ 109 has a lens built in, whereas the A7 IV 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 A7 IV and their specifications in the Sony FE Lens Catalog.

Concerning battery life, the D-LUX Typ 109 gets 300 shots out of its Leica BP-DC15 battery, while the A7 IV can take 580 images on a single charge of its Sony NP-FZ100 power pack. The power pack in the A7 IV 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 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 D-LUX Typ 109 was launched at a lower price than the A7 IV, despite having a lens built in. 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 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 more expensive and lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Leica D-LUX Typ 109 features a Four Thirds sensor and the Sony A7 IV a full frame sensor. The sensor area in the A7 IV is 364 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 2.0 and 1.0. The sensor in the D-LUX Typ 109 has a native 4:3 aspect ratio, while the one in the A7 IV offers a 3:2 aspect. The D-LUX Typ 109 has the particularity of featuring a switch that allows to toggle between multiple aspect ratios, while maintaining the same field of view and full image resolution.

Leica D-LUX Typ 109 and Sony A7 IV sensor measures

With 32.7MP, the A7 IV offers a higher resolution than the D-LUX Typ 109 (12.7MP), but the A7 IV nevertheless has larger individual pixels (pixel pitch of 5.12μm versus 3.82μm for the D-LUX Typ 109) due to its larger sensor. Moreover, the A7 IV is a much more recent model (by 7 years and 1 month) than the D-LUX Typ 109, 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 Leica D-LUX Typ 109 are 20.6 x 15.4 inches or 52.2 x 39.2 cm for good quality, 16.4 x 12.4 inches or 41.8 x 31.4 cm for very good quality, and 13.7 x 10.3 inches or 34.8 x 26.1 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 Leica D-LUX (Typ 109) has a native sensitivity range from ISO 200 to ISO 12500, which can be extended to ISO 100-25600. 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 D-LUX Typ 109 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.

Note: *) Information refers to the mechanical shutter, unless the camera only has an electronic one.

One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The A7 IV has a touchscreen, while the D-LUX Typ 109 has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.

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 D-LUX Typ 109 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 Leica D-LUX Typ 109 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 D-LUX Typ 109 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 D-LUX Typ 109 only has one slot. The A7 IV supports UHS-II cards (on both slots), while the D-LUX Typ 109 can use UHS-I cards.

It is notable that the A7 IV has a microphone port, which can help to improve the quality of audio recordings by attaching an external microphone. The D-LUX Typ 109 does not feature such a mic input.

The A7 IV is a recent model that features in the current product line-up of Sony. In contrast, the D-LUX Typ 109 has been discontinued (but can be found pre-owned on ebay). As a replacement in the same line of cameras, the D-LUX Typ 109 was succeeded by the Leica D-LUX 7. Further information on the features and operation of the D-LUX Typ 109 and A7 IV can be found, respectively, in the Leica D-LUX Typ 109 Manual (free pdf) or the online Sony A7 IV Manual.

If the count of relative strengths (bullet points above) is taken as a measure, the A7 IV is the clear winner of the contest (27 : 10 points). However, the relevance of individual strengths will vary across photographers, so that you might want to apply your own weighing scheme to the summary points when reflecting and deciding 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.

D-LUX Typ 109 10:27 A7 IV

How about other alternatives? Do the specifications of the Leica D-LUX Typ 109 and the Sony A7 IV place the cameras among the top in their class? Find out in the latest Best Travel-Zoom 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 says little about, for example, the shooting experience and imaging performance of the D-LUX Typ 109 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.

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 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.
