Pentax K-7 Review

Review based on a production Pentax K-5
with firmware 1.0.1 In terms of design and operation of new K5 is all but identical to K-7. For this reason, to get a ' 360 ' view of the K-7 body design and operation that we recommend, therefore, not only reading this review, but also the relevant sections in our full review of Pentax K-7.When the K10D was launched in September 2006 was the first foray of Pentax in DSLR market, competitors ' passionate ' when with rivals such as the Canon EOS 30 D and the Nikon D200. Four years later in 2010 passionate sector of the market is competitive as ever and the K-5, Pentax's latest offering ' serious amateur photographer?, will have to fight for consumers ' attention with the likes of Canon 7 D, Nikon D7000 and D300S and the Olympus E-3. At an MSRP of $ 1600 (body only) to launch the K-5 is currently at a similar price as its main competitors, but we expect that the price of road to go soon.At first glance the K-5 is virtually indistinguishable from the K-7 (in some markets that the K-7 will remain in line with the Pentax K-5). Apart from further ' Fx ' (which stands for ' flex ') the RAW button label and customizable a subtle redesign of AF lighting his rear there are considerable differences between the K-5 and its predecessor the K-7. However, there is more news to be found under the hood-new component of the most remarkable of the K-5 is a megapixel CMOS sensor, that 16.3 is probably closely related to the sensors inside the Nikon D7000 and Sony SLT-55. The new sensor brings a greater maximum sensitivity (ISO 51200 in expanded mode, the highest on any camera APS-C data), faster continuous shooting (7 fps vs the K-7 5.2 fps) and a 1080p full HD video mode (the K-7 offered a maximum video resolution: 1024 x 1536 pixels rather non-standard). Other enhancements include an updated system SAFOX IX + AF, inherited from the recently inaugurated 645 D medium format, which features-color detection, the most extensive coverage of the AF points and speed improved. New horizon is also an electronic two axes (now with step as indication of roll) and a few extra digital filters and custom image modes. Despite the changes, however, existing users of K-7 will no doubt take very little time adjustment if they decide to upgrade to the new model. The K-5 has exactly the same size as its predecessor, the K-7. The body of stainless steel and magnesium alloy is chunkier newest entry-level DSLR top of Pentax K-r (pictured on the left), but still relatively compact for a camera in its class.

Although it might appear to be a near-clone of K-7, K-5 offers some significant improvements in the specification. Here's a summary of the key features:

16.3MP CMOS sensorISO sensitivity over 80-carte (equivalent) 1080p HD movie mode in camera film editing external microphone functionalitySocket inputTriple-axis based on Sensor shake (fix horizontal, vertical and rotational) new SAFOX IX + 11 AF points reduction system (improved K-7) support for older Pentax lenses with manual opening ringsMagnesium alloy body shellImproved handheld HDR function (only JPEG), continuous shooting at 100% coverage viewfinder 7 fps (0.92 x magnification) choice of PEF or DNG files from 3 '', 921 k pixel LCD screen

The following table shows the specific differences between K-5 's predecessor, the K-7 and the newly released K-r. Apart from the new sensor, the differences between the K-5 and the old K-7 are quite subtle. It is clear that the Pentax has opted for selective improvements rather than a complete overhaul.
