Nikon D40 Review

People are going to have the opinion that Nikon is either silly or insane for releasing a new digital SLR camera with only 6 megapixels, and those people are going to exist. After all, Nikon’s competitors and Nikon itself both sell cameras with 10 megapixels that are within the price range of average consumers.

On the other hand, that might reflect how caught up in the megapixel battle we all have gotten. After all, image quality doesn’t depend exclusively on megapixels. Based on our tests, the most recent 10-megapixel models appear to have an inherent level of sharpness that is marginally superior to that of a 6-megapixel SLR, but not significantly. Moreover, because of the smaller pixels, there appears to be an increase in noise roughly proportionate to the size of the rise.

All of this suggests that we shouldn’t immediately dismiss digital single-lens reflex cameras with 6 megapixels of resolution just because there is a tendency to get caught up in the numbers game.

The D40 is not simply a scaled-down or “refreshed” version of the D50. Instead, it is an entirely different camera with a much smaller body. However, the change in size isn’t noticeable until you put the two cameras next to each other and look at them side-by-side.

The decrease in body height is an unfortunate side effect of the size reduction. This indicates that you can only wrap three of your fingers around the grip on the right hand. We leveled the same criticism against the Canon EOS 400D, but the trade-off for such a small and lightweight body is that you sacrifice some functionality.

The status panel on the top plate of the D40 has also been removed. Instead, all the shooting information is shown on the new 2.5-inch LCD on the back of the camera. And it does seem quite sophisticated indeed. For example, you can select a graphical display with a circular aperture/shutter speed indicator that looks fantastic but is not especially practical.

The goal seems to provide a swift visual representation of the parameters that are now being utilized. So, for example, the aperture diaphragm will either contract or expand depending on the aperture setting you’ve selected on the camera. In actuality, you may discover that your gaze is drawn immediately to the numerical readouts that are presented alongside; consequently, after some time, you may find that you barely notice this picture.

Considering this, the “traditional” interface may be more beneficial in the long run. This then changes to more significant numerical numbers and icons to indicate the number of shots left, the focal point, and the image mode, among other things. Nevertheless, both displays appear exceptionally high quality, and Nikon seems to have learned something from Olympus’ playbook by incorporating an interactive element into its collection.

You can still adjust the ISO, white balance, and other settings by going through the menus. Still, you can make these adjustments by pressing a ‘Setting’ button on the back of the camera and using the Navidad to navigate to the option you want to alter. After you have chosen a chance and highlighted it, pressing the “OK” button will bring up a menu with different choices for that item.

Not so dumb

It has a pleasant tone, but the execution is quite sluggish. The problem is that after each shot you take, the information display turns off, and to get it back up; you have to hit the button labeled “Info,” located on the top of the device. In addition, their cameras, such as the EOS 400D, depend on the back LCD for shooting information; however, these cameras keep the LCD turned on at all times.

I have one more complaint. The information display is rather sluggish in its response to changes. Suppose you don’t give yourself a few seconds to examine whether or not the on-screen display has fully responded to your input. In that case, you risk accidentally overshooting the setting you planned to use and taking a picture with the wrong exposure settings.

Be wary of falling prey to the misconception that the D40 is a watered-down version of the D50. In-camera retouching capabilities are identical to those of the more expensive D80 model. In addition, the image optimization settings have been expanded to include the helpful Vivid Plus and Black-and-White modes.

The LCD is just 2.5 inches in size, but it boasts a resolution that is twice as high, a viewing angle that is three times as broad, and colors and tones that are significantly more accurate.

The EN-EL9 battery that comes with the D40 is a lot more compact and svelte than the EN-EL3 batteries that come with other Nikon digital SLRs, but it is still capable of 470 shots on a single charge (though maybe this has been achieved by powering down the LCD after each image).

It’s interesting to note that Nikon has limited the Number of focus points on their cameras to only three. But the vast majority of people have no problem with this. Of course, there are likely to be a significant number of people enamored with sophisticated multi-point systems that will be let down. Still, there are also expected to be many photographers who will find a welcome respite in the D40s three-point system’s simplicity and clarity. In addition, this camera’s viewfinder is substantially more significant than other non-Nikon competitors.

Ultimately, the picture quality is, without a doubt, the most crucial factor to consider. And in this regard, the D40 is comparable to the D50 since it possesses an above-average definition for a sensor with 6 megapixels, very low noise, and excellent control over exposure and white balance.

There is apparent chromatic aberration around the frame’s edges, as well as fringing around the forms that are silhouetted. Even though no changes have been made to its specifications, the 18-55mm kit lens appears to be a new version. However, considering the price point, it is to be expected that the performance is merely satisfactory.

Despite this, the price may be a potential barrier to some degree. This is because the D50 kit has been available for less than £400 for a considerable time. So even though the price of the D40 is just 450 pounds, this represents a significant increase in cost for a camera that isn’t demonstrably superior.

Quality of the Image

The image quality and the type of files that can be saved are of the utmost significance for any digital camera. We found that the D40 did a great job carrying on the proud Nikon legacy in this respect. For an entry-level SLR, it produced photographs with a quality that belied its tiny 6-megapixel resolution, which was one of the things that impressed us most about the D40.

As was the case with the D80, the photographs produced by the D40 look fantastic right after they have been taken, with the level of sharpening that has been performed producing only very few artifacts while still producing prints that look good up to 13 by 19 inches in size.

Nikon has also done wonders with their noise suppression (we suspect that the D40’s sensor is unusually “quiet” to begin with), producing pairing results at ISO 1,600, with surprisingly usable images at ISO 3,200 Ag.ain; these results were made by making awe-inspiring results at ISO 1,600.

Nikon’s D40 digital SLR camera may be one of their most significant models. It is undoubtedly their most compact and lightweight model and their most economically friendly option, and it comes standard with one of their more respectable kit lenses. However, it is notable that this is the company’s first digital SLR camera that does not support autofocus for its extensive lineup of lenses, many of which do not have AF motors built in.

This was a move that, in the larger scheme of things, was not unexpected. Although frustrating to some, it is unlikely to be of too much concern for the typical person who buys a D40 camera (those with more specific lens requirements are expected to go for the D80).

When we tested the D80, one of the aspects that particularly struck us was how responsive it was; it gave the photographer the impression that there was an instant link between themselves and the camera.

So you can imagine how pleased I was to discover that the priority on responsiveness has been maintained even in the more cost-effective D40. As a result, the D40 doesn’t feel any slower to operate. On the contrary, for some tasks, it is faster thanks to smaller files, except for a slightly slower viewfinder blackout and presumably slower auto-focus (although these factors were not measured).

When you make a digital SLR, you are also effectively designing the ‘film’ that will be permanently locked into it (we have seen very few firmware updates that improve image quality; this is primarily because the ‘heavy processing’ has to be done in hardware, not software). However, Nikon has ensured no corners were cut in image processing.

The image quality was sufficient to call into question any purported benefits of an eight-megapixel digital SLR and was arguably the best of any contemporary six-megapixel digital SLR.
