Specification
This is the first half of nearly identical twins from Pentax. The K-5 II is an updated version of the highly regarded K-5. The K-5 IIs, its sibling without anti-aliasing filter, will be reviewed soon. On the face of it, we have here an identical camera to the original K-5, so we need to explore what improvements have been made, whether or not the upgrade would be sufficient for existing K-5 users and whether or not this new model will tempt new purchasers into the Pentax system. The K-5 was an Editor's Choice, so the new model has much to live up to and exceed, if it can.
Pentax K-5 II Features
The K-5 II is an APS-C DSLR with a Sony sensor, well tried and tested, using 16.28MP. It utilises the well established Pentax K mount, opening up the possibility of using almost any Pentax lens ever made. Via adapters, this backwards compatibility can extend back to even the 1950s Asahiflex lenses and of course the ubiquitous M42 screw mount lenses of the Spotmatic era, albeit with some limitations. Looking more to the present, there is a wide range of current Pentax AF lenses, with new offerings on the way to broaden the repertoire even more.
In-body shake reduction (SR) can be used with any lens or accessory and is proven already to bring a 3 stop or more advantage. Weather resistance to body and many lenses means all-weather use. The magnesium alloy shell is rugged and feels solid and dependable, but still within a remarkably compact package. Live View and Movie Mode plus a wide array of image style options round out a very complete and professional specification. An impressive 7fps is also available when needed.
Remarkable low light performance was a feature of the K-5, so we shall see how the K-5 II compares. The upgraded AF module is also an area of interest. Will this be a dramatic or just a subtle improvement of the original K-5?

Pentax K-5 II Handling
From opening the package it is evident that all the components have been well put together. The quality of finish on all the items, be it the camera, the battery, the charger, is very high. Switches operate firmly and smoothly, with no play. Access doors seal closed with precision. The lens operates without any feeling of sloppiness.
In terms of ergonomics I have used many cameras, but have always come back to Pentax. The old advertising slogan “Simply hold a Pentax” rings as true today as it did when the Spotmatic was released in 1964. Controls are comfortable and well placed, and overall it is an efficient product that feels good in the hands.
The one small design feature that has been left unchanged but could do with improvement is the card access door. This is quite cramped and can be awkward, making removal of the SD card potentially tricky. However, it does get easier with practice, but a little more room would be a considerable improvement. This is really the only niggle in what is basically an excellent ergonomic design.
The menu system is logical and works just fine. It is easy to use and has consistent and reliable logic throughout. The display is clear and if we should be in any doubt an explanation of any particular setting is displayed on screen.
Battery life, using the same Dli90 battery as the K-5, is quoted at approx. 740 images with 50% flash usage and 980 with no flash. 440 minutes of movie playback is also quoted. These figures are using the CIPA standard at under 23C. In this test after two intensive days of use, the battery indicator still reads fully charged, so the implication is that battery life will not be a problem.
| Shutter response | 0.05 secs | |
| Focus / shutter response (wide) | 0.65 secs (1.9s in live view) | |
| Focus / shutter response (full-zoom) | 0.75 secs (2.4s in live view) | |
| Switch on Time to Taking a Photo | 0.5 secs | |
| Shot to Shot without Flash | 0.2 secs | |
| Shot to Shot with Flash | 1.15 secs | |
| Continuous Shooting | 7 fps | |
| Continuous Shooting - Flash | 1 fps | |
| Continuous Shooting - RAW | 8 fps |
Start up of the camera is virtually instantaneous. By the time the finger has moved from the on switch to the shutter release, everything is ready to go. Shutter response is slick and aided by a predictable meter on position and smooth release.
In speed tests the K-5 II easily exceeds the quoted specification. I managed 32 JPEGs before the buffer was filled and 26 RAW images, compared to the quoted 30 and 20 respectively.

The field test included some atrocious weather, but of course the weather resistance means that we can just carry on and still shoot images with complete freedom. This is one of the major advances in recent DSLR design because of the freedom it brings in rugged conditions.
Exposure is very similar to the original K-5 and my preference is to permanently set -0.3EV compensation. This gives perfect results, especially when using centre weighted metering. Matrix metering is equally consistent, offering a slightly lighter end result, but many photographers may prefer to take control of the decision making themselves. Spot metering is also accurate and very useful for especially spot-lit subjects.
Exposure compensation can be used where necessary and is conveniently accessed by a dedicated button. Generally, the amount of correction needed is quite modest using all the provided metering patterns. There is no tendency to over-expose and lose the highlights, in part due to accurate metering and in part due to a wide dynamic range.
Focusing is possibly marginally faster than the K-5, but there seems to be very little in it. What does seem remarkable is that focus can now be achieved in virtual darkness, even when the subject is dark itself. These are conditions where manual focusing would be beyond most eyes, so it is quite an achievement. In brighter light, focusing is fast and accurate. In LV mode, there also seems to have been an improvement in focusing speed.
Some shots may benefit from Distortion Correction and Lateral Chromatic Aberration Correction. Provided this sort of feature does not become an excuse for short cuts in lens design, both these are to be welcomed. They work well. Architectural subjects can be rendered with straight edges. Colour fringing can be impressively removed from, for example, branches silhouetted against a bright sky.
Pentax K-5 II ISO test images
 1/4 sec | f/5.6 | 55.0 mm | ISO 80 |  1/5 sec | f/5.6 | 55.0 mm | ISO 100 |  1/10 sec | f/5.6 | 55.0 mm | ISO 200 |  1/20 sec | f/5.6 | 55.0 mm | ISO 400 |
 1/40 sec | f/5.6 | 55.0 mm | ISO 800 |  1/80 sec | f/5.6 | 55.0 mm | ISO 1600 |  1/160 sec | f/6.3 | 55.0 mm | ISO 3200 |  1/200 sec | f/8.0 | 55.0 mm | ISO 6400 |
 1/250 sec | f/10.0 | 55.0 mm | ISO 12800 |  1/400 sec | f/11.0 | 55.0 mm | ISO 25600 |  1/640 sec | f/11.0 | 55.0 mm | ISO 51200 |
Noise is exceptionally well controlled and for most purposes I would be happy with images shot up to ISO1600 with no caveat whatsoever. From ISO3200 onwards we see steady deterioration, but to be fair even at ISO51200 we can expect an image in virtually no light at all. To be shooting street images at night and find the kit lens can deliver with shutter speeds of maybe 1/100s is absolutely worthwhile to have. At the highest ISO values there will be noise and soft images, but film could not compete with the quality obtainable and there are few DSLRS that can deliver the same performance of this Pentax.
Pentax K-5 II White-balance test images
 AWB Tung Warm Off | 1/13 sec | f/4.0 | 24.4 mm | ISO 100 |  AWB Tung Warm On | 1/13 sec | f/4.0 | 24.4 mm | ISO 100 |  Tungsten Preset | 1/13 sec | f/4.0 | 24.4 mm | ISO 100 |
 AWB Fluorescent | 1/4 sec | f/4.0 | 24.4 mm | ISO 100 |  Fluorescent Preset | 1/4 sec | f/4.0 | 24.4 mm | ISO 100 |
AWB (Auto White Balance) generally proves to be very reliable. In overcast conditions it may tend towards a coolness that can be corrected by switching to the most suitable preset. Generally, I would use Daylight setting outdoors, but for warmer colour still Cloudy and even Shade work very well. Incandescent and Fluorescent presets are excellent. There is even a choice between fixed values and approximate values that the camera will then adjust over a limited range.
Resolution and image quality in general are beyond reproach, something already well established with the K-5. The K-5 II maintains this standard and amongst APS-C DSLRs this is about as good as we have.

There is a choice of lenses supplied with the K-5 II and here we have the SMC Pentax-DA 15-55mm 1:3.5-5.6 AL WR. The lens is well finished in high quality plastics and is weather sealed. This is a simplified weather resistance but it has been proven to be highly effective in resisting the ingress of water.
The lens performs exceptionally well for an inexpensive kit zoom, delivering very sharp, colourful and flare free images at medium apertures. Wide open and fully closed down the lens is still perfectly usable, but sharpness does suffer, as expected. There is the usual barrel distortion at wide angles, moving to pincushion distortion at the longer end. The in-camera distortion correction handles this well and is useful for any shots where straight edges are desirable. Using this feature does, however, take up processing time and slow down the picture taking process.
Purple / green fringing is well controlled but does become visible in extreme situations. This can be corrected in-camera, with impressive results.
Flare resistance is excellent, but of course can be induced when the sun is in frame or just out of frame. Use of the supplied hood is recommended at all times and flare is rarely a problem. All in all, an excellent standard zoom.

There are a large selection of digital filters available and exploring these would be a review in itself. All have creative possibilities and it is worth looking into the menus and trying things out. We can start simply with picture styles, and for everyday using Natural produces the most realistic colours. The default is Bright and although it has been used for this test I would normally revert to Natural. This is a matter of personal taste, not right or wrong. Digital filter options include Toy Camera, Retro, High Contrast, Extract Colour, Soft, Starburst and Fish-eye.
Pentax K-5 II Other sample images
 Pentax K5II WB AWB | 1/50 sec | f/11.0 | 37.5 mm | ISO 200 |  Pentax K5II WB Cloudy | 1/50 sec | f/11.0 | 37.5 mm | ISO 200 |  Pentax K5II WB Daylight | 1/50 sec | f/11.0 | 37.5 mm | ISO 200 |  Pentax K5II WB Shade | 1/50 sec | f/11.0 | 37.5 mm | ISO 200 |
 HDR Weak | 1/50 sec | f/11.0 | 37.5 mm | ISO 200 |  HDR Medium | 1/40 sec | f/11.0 | 37.5 mm | ISO 200 |  HDR Strong | 1/30 sec | f/11.0 | 37.5 mm | ISO 200 |
HDR in camera is a convenient way to try this technique without purchasing stand alone programs, although the effect available is limited. The various options have adjustable parameters themselves, so the range of options is vast.
Video - Movie mode works well, with a mono microphone built in and a jack provided for a stereo mike. Quality seems good and the microphone does not seem to pick up too much camera noise. Panning is smooth and the zooming action of the lens is also smooth enough to prevent any glitches in the picture. Another video can be seen on our YouTube channel.
Value for Money
New introductions usually arrive at a high price that settles down after a while. This is the price we pay for being an early adopter of new technology. In this case, both the K-5 II and the K-5 IIs seem to have been brought in at quite a competitive price level from the start. This is exceptionally good value.
However, for existing Pentax users who own the K-5 the value in an upgrade is far less clear. There is an improvement in some areas of performance, as noted, but these are not major steps for what is basically already a superb camera.
For users new to Pentax the value for money is without any doubt. This is a very fine piece of kit that performs well and reliably. It builds upon an already excellent record, giving us a very competitive price and the double value of an established design with any glitches already ironed out. The K-5 II can hold its head high amongst the alternatives - alternatives include the weather sealed Sony Alpha A77, and non-weather sealed Nikon D5200, both with 24 megapixel sensors.
Pentax K-5 II Verdict
The Pentax K-5 II is a rugged, magnesium alloy bodied, weatherproof, well designed and high quality camera with a kit zoom that is really very good indeed, and provides a package that looks very exciting against its rivals. It is more compact, arguably slicker in operation and provides the highest standards at a relatively low price level. There's not much to dislike, so the K-5 can be totally recommended.
The only caveat that remains is that, while stocks last, the original K-5 still offers most of what the K-5 II can do, and that may well be a better option in terms of cost if the low light AF performance improvement is not an issue. Prospective buyers may be well advised to move quickly on that option, before it is gone and no longer a decision to be made.

I suppose it's logical that if there's no air gap there might be less chance of fogging of the screen in bad weather. Not that I've ever noticed any of that either.
Best regards, John
K5iis and a couple of lenses.
K-5, Mz5n, ME & assorted manual and AF lenses ( + my beloved Rolleiflex.....)
"K-5 II or K-5 IIs?" is a different matter, yet to be addressed.
Not picky at all Elleygreen, good feedback, and thanks for that.
Best regards, John

Don't think I've missed it in the above, but if I recall in addition to improved AF, there was also improved visibility on the rear screen compared to the basic K-5 - is this so?
