I used my first Nikon D40 camera for about 3 years, then I sold it, and a few years later, in 2015 I bought it again. Now I have a lot of practical experience with the Nikon D40, which I share in this review.
The Nikon D40 was introduced on November 16, 2006, and became the fourteenth full-fledged Nikon digital SLR camera. Before its release, the following Nikon D1 cameras already existed, D1h, D1x, D100, D2h, D70, D2x, D2hs, D70s, D50, D200, D2xs, D80 (the list is shown in the order the cameras were released). Nikon D40 has opened a new class of Nikon cameras. Like Nikon D50, Nikon D40 belongs to the line of amateur cameras, but unlike all of the above cameras, the Nikon D40 was taken away from a very important thing - the focusing motor, which is responsible for autofocusing with non-motorized lenses like 'AF'. Thus, all Nikon D40 owners were automatically forced to use more modern and sometimes more expensive lenses such as AF-S и AF-I. Many Nikon users cursed the company for taking away the Nikon D40's compatibility with a huge (really very large) fleet of old autofocus optics. On the other hand, the Nikon D40 turned out to be a very cheap camera, which is why it was bought by a huge number of users. Subsequently, Nikon did not pay attention to user complaints and continued the line of cameras, for which it was Nikon D40 that became the basis.
This camera is the `` youngest '', the slowest, with the worst focusing system and the simplest camera in the lineup of all digital SLR cameras Nikon... Don't expect stunning performance figures from it. If you need a more serious amateur camera for photography, then you should pay attention to the modern, latest and most 'feature-packed' device in this line - Nikon D5600... The Nikon D40 baby remains just a tool for amateur photographers who don't need modern 'gadgets'.

Compared to more advanced cameras, the Nikon D40 does not have the following important functions:
- No built-in focus motor
- There is no front selector for the index finger of the right hand. This makes it difficult to configure many parameters. This selector was first thrown out of Nikon D50.
- There is no high speed sync function with Nikon external flash units.
- There is no function to control external flashes in automatic mode using the creative lighting system Nikon CLS.
- There is no diaphragm rheostat for working with manual optics.
- There is no way to shoot video.
- The camera does not know how to shoot panoramas, HDR, there is no time-lapse function, there is no bracketing, there is no function ADL, there is no control of vignetting, chromatic aberration, distortion and a million modern lotions typical of modern cameras.
But Nikon D40 retains the main thing - a large sensor. Physical matrix size (sensor) the Nikon D40 is the same as on modern expensive Nikon DX cameras: Nikon D7100, D7200, D5500, D5300, D3300 etc. One of the key differences between a DSLR and an ordinary digital compact is matrix size. In ideal shooting conditions, the Nikon D40 allows you to get the result on par with any modern Nikon DX camera.

Nikon D40 is Nikon's slowest DSLR camera. Maximum burst speed is only 2.5 frames per second... Its predecessor had the same low burst speed - Nikon D50. But not everything is so bad, if you delve into the characteristics of other cameras, you can find that professional cameras Nikon D300 и D300s also lower their speed to a miserable 2.5 frames per second during shooting with 14 bit color depth in RAW format. And also, if you recall that the TOP legendary camera Nikon D3X lowers burst speed to lean 1.8 frames per second while shooting in RAW format with 14 bit color depth, the Nikon D40 doesn’t seem so slow at all.
When shooting at ISO HI1 (equivalent to ISO 3200), the burst speed drops to 1 fps, because the Nikon D40 is still the slowest camera in the entire Nikon DSLR family.
Frame buffer the Nikon D40 is also small and is:
- 4 frames in RAW format with all disabled advanced settings
- 3 frames in RAW + JPEG L BASIC format with all advanced settings disabled
- 8 frames in JPEG, L, FINE format with all advanced settings disabled
- 12 frames in JPEG, L, NORM format with all advanced settings disabled
- 18 frames in JPEG, L, BASIC format with all advanced settings disabled
- 60 frames in JPEG, S, BASIC format with all advanced settings disabled
- 3 frames in RAW format with all advanced settings enabled
- 2 frames in RAW + JPEG L BASIC format with all additional settings included
- 7 frames JPEG, L, FINE with all advanced settings enabled
- 11 frames JPEG, L, NORM with all advanced settings included
- 17 frames in JPEG, L, BASIC format with all advanced settings included
- 59 frames JPEG, S, BASIC with all advanced settings enabled
Please note that the Nikon D40 can only shoot in JPEG L BASIC quality when using RAW + JPEG.
Nikon D40 uses the most primitive Multi-CAM 530 focusing systeminstalled in only 3 cameras: Nikon D40, D40x, D60... In the future, this focusing module was abandoned. Unfortunately, the Nikon D40 has only 3 focusing points, only one center is cruciform. The camera tenaciously holds the subject, but it is quite difficult for it to keep track of moving objects. Also note that the Nikon D40 in focus mode AF-C has focus priority over shutter release priority. This little thing greatly interferes with work and is described by me in a separate article 'Nikon entry-level cameras and focus priority'.
Nikon D40 allows you to manually select only 5 ISO values: 200, 400, 800, 1600, HI (3200) units. Given that the Nikon D40 is the shortest excerpt equals 1/4000 s, sometimes the minimum ISO 200 can play a trick when using high-aperture optics.
Measurement exposure is 420 segment RGB sensor, which is used in a huge number of other cameras (for example, in Nikon D3400, D5100, D90 etc.). But the Nikon D40 froze exposure often carried out with errors, very often the camera likes to overexpose 2/3 steps. I do not know what this may be connected with. Very often you have to make additional adjustments from -0,3 to -1 2/3 steps.
The camera slows down a bit when turning on the display and when corrected exposure (while the display is activated, you can skip the frame).
Helpful advice - Set the programmable button to change the ISO, it will be a little easier to work with the camera. To add charm to the camera, turn off the siren (sound notification), which beeps when focusing. For more set the sharpness and color in the camera to 'Optim. snapshot -> VI '.
And what about Nikon D40x? Nikon D40x was introduced 4 months after the release of Nikon D40. The main difference in D40x there was another sensor for 10 megapixels. The letter 'x' after the name of the Nikon camera just speaks of the increase in the number of pixels on the sensor. In general Nikon D40 and D40x very similar, in something the Nikon D40 is even better than Nikon D40x. All the differences between the Nikon D40 and D40x will find in the Nikon D40x review.

My experience or what really?
In fact, everything is simple, Nikon D40 is the last camera on the legendary 6-megapixel Sony ICX-453-AQ sensor. A list of all Nikon DSLR cameras and their sensors can be found at this link. Older cameras use the same sensor. Nikon D70, D70s и D50that delight the eye with a nice picture. Older camera Nikon D100 uses a similar matrix, but still different from the one on the Nikon D40. CCD matrices of these old men give a very nice color, for which they are appreciated.
Unlike Nikon D70, D70s, D50 и D100 Nikon D40 camera is the only one that uses a more modern image processor (processor), similar to the processor (processor) in cameras D200, D80, D40x. This processor allows ISO HI1 (ISO 3200 equivalent) and DL function for RAW images (this function was not available on previous models D50, D70, D70s etc.). A list of all the processors used in Nikon cameras can be found at this link.
Working with cameras on old 6-megapixel CCD matrices, I came to the conclusion that on-camera JPEG with Nikon D40 is the most pleasant. The Nikon D40 shots are some of the most enjoyable ones I got right away in on-camera JPEG. Of course, I really love cameras Fujifilm FinePix S5 Pro и Fujifilm FinePix S3 Pro, but with the Nikon D40, sometimes there are much fewer problems to achieve a good result.
Subjectively - Nikon D40 is my favorite camera... I've had about 5 different Nikon D40s over the years. The last one already has mileage more than 150.000.
Nikon D40 body on the secondary market can be found for 70-100 USD - it is one of the cheapest SLR cameras of all time. For 80-100 USD you can find a pretty super-zoom to it Nikon DX AF-S Nikkor 18-135mm 1: 3.5-5.6G ED SWM IF Aspherical or Nikon AF-S Nikkor 18-70mm 1: 3.5-4.5G ED DX SWM IF Aspherical and shoot for your own pleasure. My practice has shown that the cheapest and most functional set is just a bunch of Nikon D40 and Nikon DX AF-S Nikkor 18-135m 1: 3.5-5.6G ED SWM IF Aspherical.
Low-priced lenses are great for creative shooting. Nikon 35 / 1.8G DX, Nikon 50 / 1.8G, Yongnuo 35 / 2 и Yongnuo 50 / 1.8.
Prices for modern Nikon cameras in popular stores can look at this link.
Perhaps someone is selling d40 looking for myself?
All Avito is littered with them with olkh, is this camera rare?)
The olkh is full of divorce, I did not look at Avito
Well, I would not say straight that it is overwhelmed.
And you go to Avito, and type in the search "d40"
I can sell mine, for a symbolic value
Good afternoon, Arkady. For what nominal fee can you give the Nikon D40?
At one time it was my first Nikon SLR camera, I bought it in 2007. Actually, after this camera, I became Nikonovod forever.)
$ 25 and only if you are in Ukraine :). This camera has a mileage of 140.000 and a non-working built-in flash. The last pictures from her here.
In the right hands, the D40 is capable of making many modern crop cameras.
I will live until autumn - I will buy it for myself. For the second time

The seagulls and the sunset are very nice.
What is the percentage of sharps in frames where 50 is 1.8? I noticed excellent sharpness. This is not found on modern multi-pixel cameras, even with a good resolution fix.
> This is not found on modern multi-pixel cameras, even with a good resolution fix
If you have blurry photos with a high-quality working lens, it means that you are doing something wrong (too slow shutter speed, inaccurate focusing, inappropriate state of the atmosphere (for a telephoto lens and far-away subjects), the sensor / lens stabilizer is on when the camera is mounted on a tripod , tripod shake at slow shutter speeds, etc.), or the camera is faulty.
I am familiar with the physics of the process. I'm talking about pixel-by-pixel sharpness, real resolutions in mp, a detailed comparison, in ideal, of course, conditions for image quality. I compared the sources from Sini of the 3rd line from the watering can M (45mp), I myself shot on a row of cameras, with a tripod, etc. ... In multi-pixel frames, I never saw detail and pixel-by-pixel tonal contrast at 100 crop of what can be seen in the same line of units from canon or from nikon, yes even at 10, 20, 30d, 5d, on nikon flagships ... But I often saw it - pixel mess, a general feeling of similarity of interpolation, etc. ... I think it's just a ceiling, again, the theme of the war of megapixels is endless. Although, the programs for in-camera processing, improvements, it is possible that they will make adjustments here, as they are now implemented on a micro, for example.
“Often seen” - I’m talking about multi-pixel ff, of course
I bought myself for 30 bucks with a mileage of 31 thousand, yes colors. when compared with the D3100, you don’t need to process more realistic photos, but the landscape is much worse, I don’t know how Arkady takes such photos, I tried a whale lens and 50 1,8, the detail is much worse
This is because Arkady d40 has Japanese, and you have Chinese, most likely :-/
I take back my words. As it turned out, the Nikon D40 shoots great in good light, and I took all the photos in poor light, it was sunny yesterday and yes, the photo is better than the D700. Even with the D40, you can’t pull anything out of RAW, and you don’t need to
for someone, the LuAZ-969A was like the Chevrolet Blazer S series :-))))))
