Nikon D40X vs Panasonic GF1
The Nikon D40X and the Panasonic Lumix DMC-GF1 are two digital cameras that were revealed to the public, respectively, in March 2007 and September 2009. The D40X is a DSLR, while the GF1 is a mirrorless interchangeable lens camera. The cameras are based on an APS-C (D40X) and a Four Thirds (GF1) sensor. The Nikon has a resolution of 10 megapixels, whereas the Panasonic provides 12 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 D40X and the Panasonic Lumix DMC-GF1? 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 Nikon D40X and the Panasonic GF1 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 size dimensions are rounded to the nearest millimeter.
The D40X can be obtained in two different colors (black, silver), while the GF1 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 GF1 is notably smaller (28 percent) than the Nikon D40X. Moreover, the GF1 is markedly lighter (26 percent) than the D40X. In this context, it is worth noting that neither the D40X nor the GF1 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. A larger imaging sensor will tend to go along with bigger and heavier lenses, although exceptions exist. You can compare the optics available for the two cameras in the Nikon Lens Catalog (D40X) and the Micro Four Thirds Lens Catalog (GF1). Mirrorless cameras, such as the GF1, 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 D40X gets 520 shots out of its Nikon EN-EL9 battery, while the GF1 can take 380 images on a single charge of its Panasonic DMW-BLB13 power pack.
The adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives. 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.

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 D40X was somewhat cheaper (by 3 percent) than the GF1 at launch, but both cameras fall into the same price category. 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.
Sensor comparison
The size of the imaging sensor is a crucial determinant 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. 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.
Of the two cameras under consideration, the Nikon D40X features an APS-C sensor and the Panasonic GF1 a Four Thirds sensor. The sensor area in the GF1 is 40 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.5 and 2.0. The sensor in the D40X has a native 3:2 aspect ratio, while the one in the GF1 offers a 4:3 aspect.
Despite having a smaller sensor, the GF1 offers a higher resolution of 12 megapixels, compared with 10 MP of the D40X. 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 4.33μm versus 6.11μm for the D40X). However, it should be noted that the GF1 is much more recent (by 2 years and 5 months) than the D40X, and its sensor will have benefitted from technological advances during this time that make it possible to gather light more efficiently.
The resolution advantage of the Panasonic GF1 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the GF1 for good quality output (200 dots per inch) amounts to 20 x 15 inches or 50.8 x 38.1 cm, for very good quality (250 dpi) 16 x 12 inches or 40.6 x 30.5 cm, and for excellent quality (300 dpi) 13.3 x 10 inches or 33.9 x 25.4 cm. The corresponding values for the Nikon D40X are 19.4 x 13 inches or 49.2 x 32.9 cm for good quality, 15.5 x 10.4 inches or 39.3 x 26.3 cm for very good quality, and 12.9 x 8.6 inches or 32.8 x 21.9 cm for excellent quality prints.
The Nikon D40X has a native sensitivity range from ISO 100 to ISO 1600, which can be extended to ISO 100-3200. The corresponding ISO settings for the Panasonic Lumix DMC-GF1 are ISO 100 to ISO 3200 (no boost).
In terms of underlying technology, the D40X is build around a CCD sensor, while the GF1 uses a 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.
Consistent information on actual sensor performance is available from DXO Mark for many cameras. 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 D40X has a notably higher overall DXO score than the GF1 (overall score 9 points higher), which gives it an advantage in terms of imaging quality. This advantage is based on 1.2 bits higher color depth, 1.1 EV in additional dynamic range, and 0 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. The GF1 indeed provides for movie recording, while the D40X does not. The highest resolution format that the GF1 can use is 720/30p.
Feature comparison
Apart from body and sensor, cameras can and do differ across a range of features. For example, the D40X has an optical viewfinder, which can be very useful when shooting in bright sunlight. In contrast, the GF1 relies on live view and the rear LCD for framing. That said, the GF1 can be equipped with an optional viewfinder – the DMW-LVF1.

Both the D40X and the GF1 have been discontinued, but can regularly be found used on ebay. The D40X was replaced by the Nikon D60 , while the GF1 was followed by the Panasonic DMC-GF2. Further information on the features and operation of the D40X and GF1 can be found, respectively, in the Nikon D40X Manual (free pdf) or the online Panasonic GF1 Manual.
Review summary
So what is the bottom line? Which of the two cameras – the Nikon D40X or the Panasonic GF1 – has the upper hand? Is one clearly better than the other? Below is a summary of the relative strengths of each of the two contestants.
Arguments in favor of the Nikon D40X:
- Better image quality: Scores markedly higher (9 points) in the DXO overall assessment.
- Richer colors: Generates images with noticeably better colors (1.2 bits more color depth).
- More dynamic range: Captures a larger spectrum of light and dark details (1.1 EV of extra DR).
- Easier framing: Has an optical viewfinder for image composition and settings control.
- Longer lasting: Can take more shots (520 versus 380) on a single battery charge.
- More heavily discounted: Has been available for much longer (launched in March 2007).
Advantages of the Panasonic Lumix DMC-GF1:
- More detail: Has more megapixels (12 vs 10MP), which boosts linear resolution by 7%.
- Broader imaging potential: Can capture not only stills but also 720/30p video.
- Larger screen: Has a bigger rear LCD (3.0" vs 2.5") for image review and settings control.
- More detailed LCD: Has a higher resolution rear screen (460k vs 230k dots).
- More compact: Is smaller (119x71mm vs 124x94mm) and will fit more readily into a bag.
- Less heavy: Has a lower weight (by 137g or 26 percent) and is thus easier to take along.
- More legacy lens friendly: Can use many non-native lenses via adapters.
- More modern: Reflects 2 years and 5 months of technical progress since the D40X launch.
If the number of relative strengths (bullet points above) is taken as a guide, the GF1 emerges as the winner of the match-up (8 : 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 Nikon D40X and the Panasonic GF1 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 technical specifications can provide a useful overview of the capabilities of different cameras, it says little about, for example, the shooting experience and imaging performance of the D40X and the GF1 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 where reviews by experts come in. 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.

The above review scores should be interpreted with care, though. The assessments were made in relation to similar cameras of the same technological generation. A score, therefore, has to be seen in close connection to the price and market introduction time 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.
