A high-resolution DSLR camera for everyday photographers with most of the same features as the popular D40 model. Nikon’s successful entry-màn chơi D40 DSLR has been given an upgrade in the new D40X by replacing the 6-megapx CCD with a 10.2-megapixel imager, similar to lớn the chip used in the D80 Model. The new camera is identical to lớn the D40 in all but a few areas & shares its position as the smallest & most mammasfigata.compact DSLR cameras in Nikon’s range (although the D40’s body toàn thân isđôi mươi grams lighter). The bundled kit lens is the same 18-55milimet, F3.5-F5.5 AF-S Nikkor as you get with the D40. . .

Although the image sensor has higher resolution, its dimensions remain the same as in the D40, which means the actual photosites are considerably smaller (6.1 microns squared on the D40X mammasfigata.compared with 7.88 microns squared). While the D40X’s higher resolution output should be able to record more detail, the smaller, more densely packed photosites are more likely to lớn be affected by noise. Consequently, there’s a risk of noise-removal processing (which we found to be quite heavy) further reducing image unique from photosites with less light-capturing ability.

When mammasfigata.comparing the D40X khổng lồ other DSLR cameras, it’s useful to reflect on the plusses and minuses of the D40. The construction and functionality of both cameras is excellent, as are the thực đơn system, control layout và user interface options. Few consumer DSLRs can match the two Nikons in these respects. However, because there’s no data LCD, the monitor on both cameras must be used for setting up & replaying shots và a fair amount of toggling with the menu, info and arrow pad buttons is required lớn adjust many camera settings.

Many settings provide illustrations and a brief text explanation of how the function is applied, making this a good camera for learning the finer points of picture-taking. However, simple tasks like adjusting exposure mammasfigata.compensation, apertures and shutter speeds require users to lớn hold down one of the buttons behind the shutter release &, at the same time rotate the single mammasfigata.commvà dial. Some digital gymnastics are involved.

D-Lighting

The D-Lighting function provides fill-in lighting for backlit pictures.You can program the Function (Fn) button above sầu the lens release lớn access one setting (but only one) and hitting the zoom button takes you to a lot of other exposure controls but few dedicated buttons are provided. The new camera offers a one-stop wider sensitivity range that starts at ISO 100 (instead of 200 on the D40) but both cameras top out at ISO 1600 và have sầu a HI-1 setting that reaches ISO 3200. You can still phối the maximum sensitivity & minimum shutter tốc độ for the Auto ISO mode via the Custom menu.Like the D40, the new camera has no internal focusing motor. Consequently, only AF-S and AF-I lenses can be used with autofocusing; all other lenses will be manual focus only. Similarly, some of the metering options will only work with Nikon’s AF-S and AF-I lenses, which is bad news for potential purchaser with a suite of older Nikkors they wish to lớn keep on using.Other missing features include a depth of field pđánh giá button and exposure và trắng balance bracketing, although you vị get exposure mammasfigata.compensation of ±5 EV in increments of 1/3 EV & flash output adjustment from -3.0 to lớn +1.0 in similar increments. Improvements in power management have sầu allowed Nikon khổng lồ extkết thúc the number of shots per charge from 470 to lớn 5trăng tròn on the D40X, although the battery itself is the same as in the D40. Continuous shooting speed is also slightly higher on the D40X at 3.0 frames/second mammasfigata.compared with the D40’s 2.5 fps. However the 3 fps frame rate can only be achieved when noise reduction processing has been turned off. One mammasfigata.compromise made with the shift khổng lồ the higher-resolution sensor has been a halving of the flash synch tốc độ on the new Model. Whereas the D40 supported flash synch at 1/500 second, lượt thích the D80, the D40X is restricted to lớn 1/200 second. This can make it difficult to lớn freeze sports action & may limit photographers’ options for using flash fill in bright outdoor lighting.Although no Nikon DSLR has yet provided vibration-based dust removal or CCD-shift image stabilisation, the D40X includes a Dust-off Reference Phokhổng lồ function in the set-up menu that allows users to shoot a reference image of a white target and store the record of any dust on the image sensor. Unfortunately, the dust can only be removed when images are processed with in Nikon’s Capture NX software, which is priced at around $240.

PerformanceImademo showed some interesting differences between shots taken with the thử nghiệm camera in NEF-RAW and JPEG formats. When the raw files were processed by Imatest prior lớn evaluation, the resulting TIFF files had very low saturation levels, when mammasfigata.compared with the punchier JPEG files. The various Optimise Image settings also produced different results with Imatest’s colour tests, with the ‘Softer’ setting delivering dramatically lower saturation than the Normal và Portrait settings và the Vivid setting producing higher saturation levels. Best overall performance was with the Portrait mode, where the D40X delivered the most accurate colours and highest resolution. With other modes, colour accuracy was slightly lower than the D40 in Imatest tests although the effect on actual photographs was negligible. At 1585 line widths/px height, the D40X’s MTF50 resolution was not hugely better than the D40 (with 1430 line widths/px height), revealing there is little benefit from the higher-resolution sensor. As with the Coolpix P5000, a fair amount of undersharpening processing was applied. This may trương mục for the lower-than-expected MTF50 figures.Interestingly, despite its smaller photosites, no resolution was sacrificed as ISO sensitivities increased on the newer camera. Lateral chromatic aberration was also slightly lower with the D40X. Long exposures taken at night also yielded some excellent results và little image noise was discernible at ISO settings up to 1600.White balance performance was similar lớn the D40. Colour casts were only removed with the pre-set measurements mode. The flash required ISO 400 sensitivity to illuminate an average-sized room but spread its light evenly across the field of view of the lens at the 18mm setting.The test camera powered up in less than half a second và we measured an average capture lag of 0.2 seconds, which reduced lớn instantaneous capture with pre-focusing. However, it took almost five seconds to lớn process và store a JPEG image. The continuous shooting mode recorded 4.5MB high-resolution JPEG images at a whisker over 3 frames/second for as long as the shutter was held down. NEF-RAW files averaging just under 11MB in kích cỡ were captured at the same speed as JPEGs but the buffer could only store six images và it took just over 41 seconds khổng lồ process six raw files.

ConclusionPotential buyers must decide for themselves whether they really need 10-megapx resolution from their DSLR because, in terms of image chất lượng, there’s little to lớn choose between the D40 và the D40X. Both cameras are better suited to users with small hands and both cameras would be an excellent choice for photographers upgrading from a digicam to lớn a DSLR. But, if you’ve a suite of older Nikkor lenses you wish to keep using, neither of these cameras is suitable; you’d be better off with a D70s or D80.
