amazon Pentax K-7 reviews
The Pentax K-7 is considered the successor to the mid-range K20D, which was very successful in 2008. With a compact design that still holds the edge, the predecessor of the “predecessor” and a host of features. Modern and improved image quality, the K-7 is aimed at a wide range of photographers, from those who want to upgrade DSLRs to professional photographers. This “strong” product is also designed for travel with the ability to withstand extreme weather conditions such as dusty environments and very high humidity or temperatures as low as -10 degrees. C.
At a glance, K-7 looks like the K20D “predecessor” with the interface buttons are almost similar layout and the front of the skin is quite “bunker”. However, Pentax has reduced the three-dimensional dimensions of the K-7 to 129.5 x 96.5 x 73.6 mm (in the K20D 142 x 102 x 70 mm). The weight of 751 grams of the machine is also considered reasonable when reduced to 51 grams compared to the old version. The handle is trimmed so that the fingers can fit comfortably and operate at the same time. One point to note is that Pentax has incorporated focus illumination for its new lineup. This green light is useful when shooting at close range in low light. Other details like the mode dial and infrared sensor are almost unchanged.
The main part of the K-7 is Samsung’s 14.6 Megapixel APS-C sensor. This CMOS image sensor uses a new RGB filter, which in theory would provide better K20D noise handling. Analog signals are output via four channels at the same time, combined with the PRIME II processor for up to 5.2 frames per second, the fastest DSLR ever made.
It also enables burning 12-bit RAW files in its PEF format or Adobe’s DNG format. You can easily open these images on Adobe’s image-processing software like Photoshop CS or Lightroom without updating the database for your computer. K-7 can record 14 DNG files or 15 PEF files at the highest setting.
The K-7’s anti-shake mechanism (Pentax called “Shake Reduction”) uses multi-dimensional sensor vibrations to compensate for body vibration. The system not only eliminates horizontal-vertical vibrations, but also shakes the lens around the lens axis. This feature proved useful when used in places with complex movements such as on a train or on a trip. With the ultimate anti-shake mechanism, you can be assured of up to 2.5-4 stops above normal exposure on all compatible lenses.

Older models often use the quick motion of the sensor to push dust out of the surface, however, this is less effective when the density of dust is high and the air is high in humidity. Pentax solved the situation with DR II technology using an electrostatic ceramic layer that vibrates the primary filter membrane outside the sensor. These vibrations will eliminate more dust than traditional methods. In addition, the K-7 is equipped with a dust warning mechanism that is very useful to those who have little time to pay attention to the image of his.
The K-7 autofocus system was upgraded to 11 points based on the SAFOX VIII Plus AF sensor and a secondary color sensor. This sensor works by locating the light source of the scene to refine the autofocus process. The K-7’s 3-inch, 921,000-dot, 3-inch LCD monitor is very attractive when viewing images or taking pictures with Live View. The shutter speed is faster than most DSLRs today with a minimum speed of 1 / 8,000 seconds and a lifespan of 100,000 times. The feature set of the machine is so rich that you will spend a lot of time exploring and taking full advantage of them. For example, the machine allows you to create HDR images, fix uneven magnification, correct chromatic aberration or copyright right on the original image file. The machine also offers a huge “digital filter” and 6 dresses for you to choose from. Of course, Pentax has carefully equipped the K-7 with 720p compression of Motion JPEG video, however, the sound only stops at mono. If you want higher quality, you should invest a separate microphone plug into the 35 mm stereo jack on the camera body.
The quality of photos taken by the K-7 was rated slightly better than the equivalent models of other manufacturers. When set to default, noise reduction at high ISO is moderate at work, so images tend to be slightly damp but still retain a lot of detail. Colors are well reproduced with good saturation, almost without yellowing or too pale. SLRgear’s tests also confirmed that the K-7 delivers sharp and high-contrast photos than the Canon 50D or even the Nikon D300. The white balance of the machine also works more precisely than most DSLRs ever produced by Pentax. The ISO range of 100-6,400 is not exactly impressive, but it’s more than enough to meet the needs of photographers. Images taken at ISO 1600 can still be printed on A4 paper without causing any problems due to noise.
On the downside, the machine has a slightly complex interface and control system integrates too many features, requiring the user to have experience. HD video files use Motion JPEG codes that are quite familiar, but bulky in size. The camera also does not support autofocus while recording video. The sensor-based vibration-damping system is quite well designed, but it is inevitable that the image drift will be in some cases. In particular, the K-7 is more luckier than any of the competitors in the detailed reproducibility test in high contrast areas (however, this is not a concern). Ability of noise canceling machine is quite good but slightly less than the predecessor K20D. In some cases, lack of brightness, lack of focus and illuminator does not automatically turn on. Increasing the contrast also darkens the darker details in the image while some bright areas are slightly overdressed.
