Professional lighting equipment Pentax K-7, equipped with 40 biscuit heads, is used in the Summer Palace.

Pentax K-7 has made great innovations on the basis of previous models. The new image sensor not only supports video shooting, but also performs well in image noise control and tolerance control. In addition, the working state of the fuselage is quieter and softer, and the response speed of each shooting process is also improved. For more information about Pentax K-7, please click.

Comprehensive transformation of Pentax SLR K-7 evaluation function and performance

I see. The Pentax lens marked Limited has some obvious uniqueness.

If you feel that the image quality and maneuverability of the thin entry-level SLR can't satisfy your passionate photography enthusiasm; Professional high-end models are too expensive and bulky, so have you been trying to find a balance between them? At least when I put Pentax K-7 and SMC Pentax -Da 1: 2.8 40mm limited lenses, I seem to see this balance.

As can be seen from the above figure, K-7 is a very small model in this level of products. SMC Pentax -Da 1: 2.8 40mm limited? Cookies? After the lens, the two are matched with a very outstanding portability combination without giving up professional performance. Then, if you are a travel photographer, this combination should be an ideal choice. Smc pentax -da 1: 2.8 40mm limited edition is this lens typical? Cookies? The axial length of the lens installed on the camera is not more than 2 cm. Because it is a fixed-focus lens, SMC Pentax-Da1:2.8 40 mm Limited is better than ordinary zoom lens in dispersion and shape distortion control. The maximum aperture of f/2.8 and the equivalent focal length of 60mm are also universal. But strictly speaking, it still lacks some wide-angle performance of tourism photography. But there is nothing perfect in the world. It's really too thin, and it's really suitable for backpacks or even jeans pockets.

Sunset in the Summer Palace

With Pentax K-7 and SMC Pentax -Da 1: 2.8 40mm limited lens, the author went to the Summer Palace empty-handed, without any bag, like a relaxed tourist. My luggage was in the hotel, so I went out with my camera. In fact, the weather is not good today, and the air permeability is not ideal. Only at dusk does the sky in the Summer Palace become vivid. Then, try to take a picture of the sky and some details of the Summer Palace to see how Pentax K-7 and SMC Pentax -Da 1: 2.8 40mm limited editions perform.

"The different tolerance performance of K-7.

Adjustable sensitivity is an obvious advantage of digital camera over film machine. Although the basic latitude of digital camera is not as good as that of film at present, the dynamic range of digital camera is adjustable on the basis of adjustable sensitivity, so the contrast control of photos is quite easy. This can be achieved on film, not in a week and a half.

Seventeen-span bridge in the sunset

Digital cameras have a small tolerance, so it is easy for pictures to achieve strong contrast. Looking at the picture above, bridge opening of the 17-hole bridge is set off by the sunset? Burning? Combined with Pentax's bright color style, this picture looks very special.

This is a set of examples of dynamic range optimization. Open the scene when the light is high? Shadow optimization? Function can get higher tolerance, and the details of the shaded part will be more vivid. When shooting in the sun, you often encounter scenes that need this function.

HDR automatic synthesis effect

In addition to the simple latitude optimization function, K-7 even supports HDR (high dynamic range) automatic synthesis, and the camera can achieve higher latitude by taking multiple photos without software. The above photo is a scene with a particularly bright background (the sky is very bright, and if the lion is bright enough to shoot normally, the sky has no sense of hierarchy). Isn't it a bit too much for us to capture such an effect with HDR automatic synthesis? Hehe, because I'm from? High dynamic range shooting? Select from the options? Enhance? Of course you can choose? Standard? In order to obtain a more natural effect.

"Cookie head backlight performance is excellent.

SMC pentax -Da 1: 2.8 40mm Limited is slim, but it actually has a very lovely hood and lens cover. Of course, cuteness is not its original intention, but carelessness is cuteness. In fact, we are more concerned about its performance in use. When shooting in reverse light, a hood is especially needed to avoid the direct sunlight on the lens, which will cause the photo to turn white. Of course, this is also related to the design of the lens, and often the lens with multi-layer coating takes into account the problem of lens glare.

In addition, according to the photos taken in backlight, the image clarity of K-7 with SMC Pentax -Da 1: 2.8 40mm Limited is not very high, which is also Pentax's consistent style. It seems that K-7 never lets go? Sharp? As a selling point. As a fixed-focus lens, SMC Pentax-da1:2.8 40mm Limited controls the dispersion at the edge of the picture at a very low level, and the uniformity of the whole picture is quite good except for the large aperture above f/4.

"The natural transition caused by the large aperture of f/2.8.

Compared with non-professional small cameras, digital SLR cameras are most easily remembered as shallow and profound. The aperture of f/2.8 brings many benefits to the biscuit headband. Using it in dark light can not only ensure the shutter speed and prevent motion blur, but also create a shallow and deep effect and increase the layering of the picture. From the actual shooting effect, SMC Pentax -DA 1: 2.8 full aperture 40 mm limited lens can ensure high focus definition, while the background blur is very soft.

"The live view function makes shooting more free.

Although we don't often use the video shooting function of digital SLR cameras, the live-view function has brought us great benefits, which is very convenient when shooting at low angles (a few years ago, when the live-view function was just emerging, I always worried that it was not good to always turn on the sensor, and even advised people not to use it frequently, but now I find that with this function, I use more and more special angles, so don't worry. So far, I haven't encountered any breakdowns due to live-view or video shooting.

"Respond quickly to get more opportunities.

The faster the camera and lens react, the better your chances of capturing some key moments. The Pentax K-7 image processing has faster response speed and focus, and the fuselage response is quieter. And then what? Cookies? Because the lens assembly is small and the pan/tilt drive is more flexible, when I take some dynamic pictures with K-7 and SMC Pentax-Da 1: 2.8 40 mm, there is basically no special regret because of focusing or storage.

Although the focal length is a little longer for landscape photography, SMC Pentax-da1:2.8 40 mm Limited and K-7 can also show a landscape from many parts.
