Going beyond this snapshot of core features and characteristics, what are the differences between the Panasonic Lumix DMC-LF1 and the Pentax Q? 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

An illustration of the physical size and weight of the Panasonic LF1 and the Pentax Q is provided in the side-by-side display below. 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 Pentax Q can be obtained in two different colors (black, white), while the LF1 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 Pentax Q is notably smaller (13 percent) than the Panasonic LF1. In this context, it is worth noting that neither the LF1 nor the Pentax Q are weather-sealed.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the LF1 has a lens built in, whereas the Pentax Q is an interchangeable lens camera that requires a separate lens. Attaching the latter will add extra weight and bulk to the setup.

The power pack in the LF1 can be charged via the USB port, so that it is not always necessary to take the battery charger along when travelling.

The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators. If you want to switch the focus of the display and review another camera pair, you can move across to the CAM-parator tool and choose from the broad selection of possible camera comparisons there.

Any camera decision will naturally be influenced heavily by the price. 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 LF1 was launched at a lower price than the Pentax Q, 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.

Sensor comparison

The size of the sensor inside a digital camera is one of the key determinants 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. 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 more expensive and lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Panasonic LF1 features a 1/1.7-inch sensor and the Pentax Q a 1/2.3-inch sensor. The sensor area in the Pentax Q is 35 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 4.5 and 5.6. Both cameras feature a native aspect ratio (sensor width to sensor height) of 4:3.

Even though the LF1 has a larger sensor, both cameras offer the same resolution of 12 megapixels. This implies that the LF1 has a lower pixel density and larger individual pixels (with a pixel pitch of 1.89μm versus 1.53μm for the Pentax Q), which gives it a potential advantage in terms of light gathering capacity. In addition, the LF1 is a somewhat more recent model (by 1 year and 10 months) than the Pentax Q, and its sensor might have benefitted from technological advances during this time.

The Panasonic Lumix DMC-LF1 has a native sensitivity range from ISO 80 to ISO 6400, which can be extended to ISO 80-12800. The corresponding ISO settings for the Pentax Q are ISO 125 to ISO 6400 (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.

For many cameras, data on sensor performance has been reported by DXO Mark. This service is based on lab testing and assigns an overall score to each camera sensor, as well as ratings for dynamic range ("DXO Landscape"), color depth ("DXO Portrait"), and low-light sensitivity ("DXO Sports"). Of the two cameras under review, the LF1 has a notably higher overall DXO score than the Pentax Q (overall score 5 points higher), which gives it an advantage in terms of imaging quality. This advantage is based on 0.6 bits higher color depth, 0.5 EV in additional dynamic range, and 0.2 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.

Note: DXO values in italics represent estimates based on sensor size and age.

Many modern cameras are not only capable of taking still images, but also of capturing video footage. Both cameras under consideration have a sensor with sufficiently fast read-out times for moving pictures, but the LF1 provides a higher frame rate than the Pentax Q. It can shoot video footage at 1080/60i, while the Pentax is limited to 1080/30p.

Feature comparison

Apart from body and sensor, cameras can and do differ across a range of features. For example, the LF1 has an electronic viewfinder (200k dots), which can be very helpful when shooting in bright sunlight. In contrast, the Pentax Q relies on live view and the rear LCD for framing. That said, the Pentax Q can be equipped with an optional viewfinder – the O-VF1. The following table reports on some other key feature differences and similarities of the Panasonic LF1, the Pentax Q, and comparable cameras.

The Pentax Q 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 LF1 and the Pentax Q write their files to SDXC 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 Panasonic Lumix DMC-LF1 and Pentax Q and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the LF1 offers wifi support, while the Pentax Q does not. Wifi can be a very convenient means to transfer image data to an off-camera location.

Both the LF1 and the Pentax Q have been discontinued, but can regularly be found used on ebay. The Pentax Q was replaced by the Pentax Q10, while the LF1 does not have a direct successor. Further information on the features and operation of the LF1 and Pentax Q can be found, respectively, in the Panasonic LF1 Manual (free pdf) or the online Pentax Q Manual.

Review summary

So how do things add up? Is the Panasonic LF1 better than the Pentax Q or vice versa? A synthesis of the relative strong points of each of the models is listed below.

Reasons to prefer the Panasonic Lumix DMC-LF1:

• Better image quality: Scores markedly higher (5 points) in the DXO overall assessment.
• Better video: Provides higher movie framerates (1080/60i versus 1080/30p).
• Easier framing: Has an electronic viewfinder for image composition and settings control.
• More detailed LCD: Has a higher resolution rear screen (920k vs 460k dots).
• Faster shutter: Has higher mechanical shutter speed (1/4000s vs 1/2000s) to freeze action.
• Faster burst: Shoots at higher frequency (10 vs 1.5 flaps/sec) to capture the decisive moment.
• Ready to shoot: Has a lens built-in, whereas the Pentax Q requires a separate lens.
• Easier travel charging: Can be conveniently charged via its USB port.
• Easier file upload: Has wifi built in for automatic backup or image transfer to the web.
• Easier device pairing: Supports NFC for fast wireless image transfer over short distances.
• More affordable: Was introduced at a lower price, despite coming with a built-in lens.
• More modern: Is somewhat more recent (announced 1 year and 10 months after the Pentax Q).

Arguments in favor of the Pentax Q:

• Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
• More flexible: Takes interchangeable lenses and can thus be used with specialty optics.
• More compact: Is smaller (98x57mm vs 103x62mm) and will fit more readily into a bag.
• Better lighting: Features a hotshoe and can thus hold and trigger an external flash gun.
• More heavily discounted: Has been on the market for longer (launched in June 2011).

If the number of relative strengths (bullet points above) is taken as a guide, the LF1 is the clear winner of the match-up (12 : 5 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 Panasonic LF1 and the Pentax Q place the cameras among the top in their class? Find out in the latest Best Prime Lens Compact 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 technical specifications can provide a useful overview of the capabilities of different cameras, it remains partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the LF1 or the Pentax Q. 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 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.

The review scores listed above should be treated with care, though. The ratings are only valid when referring to cameras in the same category and of the same age. 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, please note that some of the review sites have changed their methodology and reporting over time.
