Nikon D40 vs Panasonic G1
The Nikon D40 and the Panasonic Lumix DMC-G1 are two digital cameras that were officially introduced, respectively, in November 2006 and September 2008. The D40 is a DSLR, while the G1 is a mirrorless interchangeable lens camera. The cameras are based on an APS-C (D40) and a Four Thirds (G1) sensor. The Nikon has a resolution of 6 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 D40 and the Panasonic Lumix DMC-G1? 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 D40 and the Panasonic G1. 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 dimensions are rounded to the nearest millimeter.
If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Panasonic G1 is notably smaller (11 percent) than the Nikon D40. Moreover, the G1 is markedly lighter (31 percent) than the D40. In this context, it is worth noting that neither the D40 nor the G1 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 (D40) and the Micro Four Thirds Lens Catalog (G1). Mirrorless cameras, such as the G1, 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.
The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones. If you want to switch the focus of the display and review another camera pair, just select a new right or left comparator from among the camera models in the table. Alternatively, you can also move across to the CAM-parator tool and choose from the broad selection of possible camera comparisons there.

Any camera decision will obviously take relative prices into account. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The D40 was launched at a somewhat lower price (by 17 percent) than the G1, which makes it more attractive for photographers on a tight budget. 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.
The size of the sensor inside a digital camera is one of the key determinants of image quality. A large sensor will generally have larger individual pixels that offer better low-light sensitivity, provide wider dynamic range, and have 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 Nikon D40 features an APS-C sensor and the Panasonic G1 a Four Thirds sensor. The sensor area in the G1 is 39 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 D40 has a native 3:2 aspect ratio, while the one in the G1 offers a 4:3 aspect.
Despite having a smaller sensor, the G1 offers a higher resolution of 12 megapixels, compared with 6 MP of the D40. 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 7.85μm for the D40). However, it should be noted that the G1 is a somewhat more recent model (by 1 year and 9 months) than the D40, and its sensor might have benefitted from technological advances during this time that partly offset its pixel-size disadvantage.
The resolution advantage of the Panasonic G1 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the G1 for good quality output (200 dots per inch) amounts to 20 x 15 inch or 50.8 x 38.1 cm, for very good quality (250 dpi) 16 x 12 inch or 40.6 x 30.5 cm, and for excellent quality (300 dpi) 13.3 x 10 inch or 33.9 x 25.4 cm. The corresponding values for the Nikon D40 are 15 x 10 inch or 38.2 x 25.4 cm for good quality, 12 x 8 inch or 30.6 x 20.3 cm for very good quality, and 10 x 6.7 inch or 25.5 x 16.9 cm for excellent quality prints.
The Nikon D40 has a native sensitivity range from ISO 200 to ISO 1600, which can be extended to ISO 200-3200. The corresponding ISO settings for the Panasonic Lumix DMC-G1 are ISO 100 to ISO 1600, with the possibility to increase the ISO range to 100-3200.
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"). The Overall DXO ratings for the two cameras under consideration are close, suggesting that they provide similar imaging performance. The following table provides an overview of the physical sensor characteristics, as well as the sensor quality measurements for a selection of comparators.

Apart from body and sensor, cameras can and do differ across a variety of features. For example, the G1 has an electronic viewfinder (1440k dots), while the D40 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 viewfinder in the G1 offers a wider field of view (100%) than the one in the D40 (95%), so that a larger proportion of the captured image is visible in the finder. In addition, the viewfinder of the G1 has a higher magnification (0.70x vs 0.53x), 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 D40, the Panasonic G1, and comparable cameras.

Both the D40 and the G1 have been discontinued, but can regularly be found used on eBay. The D40 was replaced by the Nikon D40X, while the G1 was followed by the Panasonic G2. 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 what conclusions can be drawn? Which of the two cameras – the Nikon D40 or the Panasonic G1 – has the upper hand? Is one clearly better than the other? The listing below highlights the relative strengths of the two models.
Reasons to prefer the Nikon D40:
- More dynamic range: Captures a larger spectrum of light and dark details (0.7 EV of extra DR).
- Brighter framing: Features an optical viewfinder for clear, lag-free composition.
- Longer lasting: Can take more shots (470 versus 410) on a single battery charge.
- More affordable: Was introduced into a lower priced segment (17 percent cheaper at launch).
- More heavily discounted: Has been on the market for longer (launched in November 2006).
Arguments in favor of the Panasonic Lumix DMC-G1:
- More detail: Has more megapixels (12 vs 6MP), which boosts linear resolution by 38%.
- More framing info: Has an electronic viewfinder that displays shooting data.
- More complete view: Has a viewfinder with a larger field of view (100% vs 95%).
- Larger viewfinder image: Features a viewfinder with a higher magnification (0.70x vs 0.53x).
- 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 flexible LCD: Has a swivel screen for odd-angle shots in portrait or landscape orientation.
- More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
- Faster burst: Shoots at higher frequency (3 vs 2.5 flaps/sec) to capture the decisive moment.
- More compact: Is smaller (124x84mm vs 124x94mm) and will fit more readily into a bag.
- Less heavy: Has a lower weight (by 162g or 31 percent) and is thus easier to take along.
- More legacy lens friendly: Can use many non-native lenses via adapters.
- More modern: Was introduced somewhat (1 year and 9 months) more recently.
If the count of individual advantages (bullet points above) is taken as a guide, the G1 is the clear winner of the contest (13 : 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 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 D40 and the Panasonic G1 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 D40 and the G1 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.
This is where reviews by experts come in. The following table reports the overall ratings of the cameras as published by some of the major camera review sites (cameralabs, dpreview, ephotozine, imaging-resource, and photographyblog). 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 were established in reference to similarly priced cameras that were available in the market at the time of the review. 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, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
