For Moirée:
When the camera arrived I first the old camera (Pentax KX) incl. Packaging photographed for the sale, which promptly resulted in a moiré on the box. After stopping down, just like 1cm further away (in not dimmed) and accordingly zoom in something it was completely gone.
I have now made more than 2,000 photos and tried to provoke Moirée again. It is not 1x "successful" me since 1 photo.
There were house facades, roofs, various clothing materials / background materials, people, animals, and much more. thereby.
Even with a background fabric, in which the Pentax Kx has ever produced a moiré, I had the K5IIs at (now already many photos) also never one.
MMN is worth the extra cost Pentax K5II because they highly valued in less than 1% (with me are's far Even if times a moiré arises, it is easy to pick up by distance change or Fade Out.
By sharpening the K5II one can obtain the focus of K5IIs (unsharpened), but to make the image more rushes. Degrees at high ISOs mMn a great advantage.
It will present the strongest possible terms its APS-C camera on the market!
Compared to other brands, they also reflected very well.
Although all Canon APS-C's noise more, Nikon D7000 has the same sensor, but is blurred, the dynamics of K5IIs itself can still keep up with the Canon 5D III.
To find a better camera than the K5II (s) you have multiples to spend at other brands.
The AF is very reliable and is still working in very dark Sitautionen. If it is too dark, there is an AF assist illuminator.
Even with external flash, the exposure is always good.
For the weather resistance Pentax is already famous. Always nice are the views of some photographers, when you're the last person who has his camera at the rain outside. The dust is therefore also very good.
The ultrasonic sensor cleaning works very well, as far as I could observe so far, the image stabilization in the sensor also (to 4LW)
The processing (hard plastic) and feel is just like a dream, it has many direct keys and a battery grip can be connected, so even large / heavy lenses are comfortable to hold.
The Sony sensor used is one of the lowest noise APS-C sensors on the market (with subsequent RAW denoising are ISO 12800 results still very usable .. reserves there are until 51200), from the Pentax with K5IIs all out tickles possible.
There is a TAV mode, I do not want to miss, and the functions are circumcised in the smallest way. There are some even functions available at the competition only from a multiple of the price;)
I'm really happy with the camera, because Pentax has done exactly right: The proven slightly improved: no teething problems, no fehlfokus and tested accessories. For this, a price that is very low for the service.
A few disadvantages there with Pentax also:
The video mode is not as well developed as in the competition (no AF while recording, not 50p, just automatic sensitivity, etc, as Sony is much more appropriate)
Pentax currently has no full-format camera in the offer,
The (studio) flash system is probably better solved eg with Nikon, Pentax still in very good usable.
The high-end lenses from other manufacturers (eg Canon 70-200 F2.8 L or similar good / expensive) have a slightly faster motor. By contrast, the cost of the competition are considerably slower than the rods AF or SDM from Pentax.
The rods AF is quite noisy, but it is possible but rather to build small, lightweight lenses that focus quickly anyway. Another benefit is when the drive improves the camera, you can tell it to each objective and must not only buy new.
Furthermore, the lens range is often regarded as very small.
Is allowed in competition all cheap lenses and unregulated lenses away and takes all usable (without adapter all since 1980, which are also all stabilized by the sensor) for Pentax and the third-party manufacturer (Sigma, Tamron, etc) added, the difference is not at all more so big. A few exceptions, there is still that cost but usually> 5000th
These are the Pentax lenses smaller and cheaper with the same / better picture quality, degree in the field of Pentax Limited (eg comparable with Zeiss).
Overall, for me very verschmerzbare disadvantages of this otherwise harmonious overall package.
