In reply to:

Medex: i did my own test today an hour ago. Conditions:
1. The lens Pentax FA* 85 f1.4 - screw drive.
2. ISO 800, about 6:30 PM.
3. Av regimen.
4. AF-C SEL9 regimen.
5. Small JPEG (12 Mpix) to not overfill buffer during test shot series.
6. Exposure 1/500.
7. F 5.6.
Result: The best result was 29 in-focus pictures out of 30.
It is more than 95 percent hit rate.
The series of pictures is available on my facebook. User name Mindaugas MG-efoto.
Another real-life test was done with aperture f1.4. 14 shots in series, 12 - in-focus. The last two are out-of-focus and that is logical - very thin DOF. The series is also available on my FB.
In my opinion, the best result is when you start shooting the object in-focus already and use AF-C SEL9, not the single point. I did not try SEL27. You simply should keep your moving object in the 9 point focus area during shooting.

solarider: "To enable af tracking you only need to be in af-C

To enable what Nikon define as 3D tracking you need to be in auto exposure and custom image (why custom image I cant understand)

All Pentax k3 and above are able to track Z axis using the HD exposure meter but only the k1 is capable of interlinking data from both the 2D PD sensor and the HD exposure sensor to predict 'swerving' Z axis motion.

As drpreview deliberately threw a swerving Z axis target at the cameras to test their 3D tracking performance it would seem sensible to me if they actually enabled that function prior to test !!"

@Rishi: I was quoting someone else and their claim.
I'm interested to know what's at the bottom of the K-1 AF just like you and the next person. Thanks for your reply.

More than a small amount of effort can go into an image. Thank you for you detailing your process.

Simon Joinson said: "I have the K1 in my hand and I can tell you that changing the Custom Image mode doesn't affect X-Y tracking at all. Setting the exposure mode to Scene Analyze Auto does affect the tracking - it disables it (and you cannot use AF-C). I think this is a translation error. I would suggest that it's trying to say that the AF-tracking uses the RTSA system, but that doesn't mean you need to 'activate' it. It would be very odd if Pentax only offered this feature in a mode where you cannot select AF-C, or if you select one specific JPEG rendering mode."

In reply to:

drummercam: I don't find the Green Button's basic "hyper-program" functionality explained at all, just mention of it as the stop down metering route, and other unstated customizations. The basic functions (not customizations) of the green button -- i.e., what it was first designed to do when it appeared on the MZ-S -- as a shortcut back to the program exposure solution from any exposure alteration, in any exposure mode, and as shortcut back to baseline from any exposure compensation (both ambient and flash), are well worth describing under the "Controls" heading.

Too bad they neglect one of the great 'goodies' Pentax has had for years.

My feeling on the K-1 is that Ricoh are feeling out the whole experience of having produced this nice looking camera. Since they're selling more than they expected and were back ordered I assume their assessment of the project should be moving forward and they'll be even more confident in future editions :- )

Hi DPR eds. Thanks for the shakedown.

By "JPEGs are soft and noisy at high ISO", does that mean the default JPEG setting when the K-1 comes right out of the box, without any adjustments to taste or best performance?

Can you please comment on Left Eye's suggestions for non-default JPEG settings? I'm not suggesting his are best - maybe there are better settings. Thank you.

In reply to:

ogl: It's the beginning of new direction of Ricoh. New video directed lenses without screw-drive with fast and noiseless motors.
It's more progressive way than KAF3. Like or not like, but it's right direction with K-mount.

New lens is 8.3 times faster at wide-angle and 1.7 times faster at telephoto end than old 55-300. Don't forget - Ricoh will produce 6 new FF lenses and 4 new APS-C in 2016-2017.
If new FF primes will be made for video mode, silent, speedy and fast with WR or AW, it will be real BIG PROGRESS for Ricoh-Pentax.

10 new lenses? smokin'.

Nice about Pentax: Pentax Hyper Program mode: https://www.youtube.com/watch?v=3yglJesVlqY

Why not throw in Pentax Hyper Manual mode while we're at it :-) https://www.youtube.com/watch?v=RjHY5uYHofA

Bob 1: A very nice entry level DSLR from Pentax! Clearly in direct competition with Canon's Rebel line... the T6s. Considering the price delta between both cameras (body only_today's B&H listing) and added features of the K-70, specs would place the K-70 on top of the pack. The T6s has been available a little over one year while the K-70 should be shipping shortly(?).

about $650
amazon shows if for $614 at the moment. https://goo.gl/WIZa3c
Of course it won't be available for a while. So get in while the price is this good.
