Mac McCreery: A general point. There are, as on any thread, some upset folk here. Please don't attack the review team, and ,in turn, perhaps the review team could reply in a more becoming manner.

Rishi Sanyal: You said 'Whatever method is current'? And 'your method' is current, is it?"

My method is ONE of the current methods. It is still one of the most effective methods for some types of photography.

Just because new technology offers different options doesn't mean that everyone needs to switch for all their work. Are we now to say "ALL cameras will be tested for their Pixel Shift capability"?

It is obvious that I am in the target market for the K-1. I shoot mostly action, & using my method of shooting, the K-1 is very good for that, with very effective AF giving me end-to-end in-focus photos in a burst. Yet had I relied on this review to make my purchasing decision, I wouldn't have bought the K-1.

That says something about the value of such reviews. They are not mainly testing the ability of people like me to come home with memory cards full of keepers. (Which is surely the point of photography?) They are testing technology trends that some potential buyers don't need.

Joe Ogiba: The PENTAX K-70 employs PENTAX's first Hybrid AF system during Live View autofocus operation. By positioning a contrast-detection AF sensor with superior focusing accuracy and a phase-matching AF sensor on the image sensor's surface, this innovative hybrid system optimizes the benefits of both AF systems to assure high-speed, pinpoint AF focusing on the subject.

Get the K-70 if you want the best AF in a Pentax DSLR. If the K-1 had that and 4K UHD like many other cameras it would be a killer camera at that price.

But the K-70's better Live View isn't suitable for action shooting, presumably.

For that, it won't come close to the K-1.

pentaust: More argumentation isn't necessary. I encourage everyone having access to a Pentax K1 to do the test himself and publish the results online. And there are already plenty of examples online showing Pentax K1 tracking capability, but, one review ignore them all. Interesting.

Barney Britton: you said "Fast jets, cars racing around a track etc., are often positioned at infinity".

Wow! Not even close!

I've been shooting those in vast numbers for many years, and it is certain that accurate AF is essential!

In fact, sometimes I don't even get the whole car within the depth of field. I have to make choice such as "do I use f/5.6 and risk not getting the whole thing in focus at 200mm or 450mm or whatever?", or "do I use f/8 and not blur the background enough and get a little bit more noise?"

Sometimes when planes are performing the "pass", where they hurtle towards one-another and just miss, I find I've panned with the one that is furthest from the camera, & got a poor shot because the closest one is out of focus, which is artistically bad. Similarly, if two racing bikes are having a tussle, it is typically important to to get the closest one to the camera in focus, for similar reasons.

Fortunately, the K-1 plus the recent FF lenses is up to it. It works!

Marathonianbull: "Limited modern full-frame lens selection"

Remove the words "modern" and "selection", then move the whole sentence from the Cons to the Pros column!

I would certainly get a K-1 for that utmost pleasure: to get to use those three famed FA Limited lenses (31mm, 43mm, 77mm)...

Speaking of other options, limited doesn't mean inexistent (some of the many available ones are actually quite modern - just releases!)

Yes. The Pentax FF lenses released in the last 14 months are:
15-30mm f/2.8
24-70mm f/2.8
70-200mm f/2.8
150-450mm f/4.5-f/5.6
28-105mm f/3.5-f.5.6

I have them all. The first 4 are "pro-grade" In my opinion). The 5th is lovely and sharp.

One key test was a man on a bike.

I shoot "things in flight" and motorsports with my K-1. I have 3 major airshows in the next few days, at which I expect it to take vast numbers of sharp photos. including fast jets. (I hope F-22, F-35A, F-35B, obviously Typhoon, and lots more!)

I really don't want to waste my time shooting a man on a bike!

(I pan. I don't use camera-tracking across the frame).

In reply to:

John McMillin: I'm not worried about lack of available Pentax lenses. There are new versions of the two lenses that every ambitious photog/lens collector seems to require, the f2.8 zooms that cover 24-200 mm. Within that range lies a range of luscious primes and Limiteds. The real shortage is in the long telephoto range. That's important to many, but still it's a market niche, not a universal weakness.

15 Pentax lenses in the "official" Pentax FF line-up dated June 2016:
5 zooms from 15mm to 450mm (as joergensmi says).
10 primes, from 31mm to 560mm.

There are also lots of legacy lenses, which I personally don't take seriously, but lots of people do. Plus lenses that are not "officially" FF but actually are (I have 2 such lenses). Plus a few important lenses from 3rd parties such as the Samyang 24mm tilt/shift (which I have).

I agree with the need for lots of more lenses, including cheaper zooms and perhaps a modernising of some of the primes. But I have a comprehensive FF system simply by buying the FF equipment that Ricoh has released over the last 14 months.

In reply to:

norman shearer: Reading all the contradictory comments about AF reminds me of the UK referendum - you just don't know what to believe. I suppose it is all comparative and those that have experienced much better AF are not afraid to say so. However I do wonder if Pentax defaults are partly to blame and user inexperience also?
Whatever, it seems clear that if Pentax could up their game with AF then they could wipe the floor with the competition. So hopefully Pentax are listening and prioritize AF development for the K2.

There are many AF settings, & lots of combinations of them, on the K-1, to suit various types of action & various shooting styles. (7 focusing areas, various selected positions, choice of priorities & other adjustments, etc).

It can be overwhelming, & people in the Pentax SLR forum & elsewhere have had lots of discussion over the last 2 months about the best choices in particular circumstances. I think Ricoh DO need to take some blame for bad choices.

I get good results by ignoring nearly all complications and using AF-C with just the center spot and panning during the burst. I can routinely get a burst of (say) 12 frames of cars, racing bikes, aircraft, with every one sharp.

But it isn't an obvious way of using the K-1, and other people probably struggle a lot. And some people don't want to use that panning style. (Also, I suspect that, having put all those extra AF points in the K-1, it might appear to be a cop-out or climb-down to recommend such an old-school shooting style!)

slcmike: Reality is never as bad or as good as internet "truth". It's possible that while "poor" by dpr standards, the AF performance of the K-1 is quite good enough for many people and their use cases. It seems that some users are capable of doing amazing work with this camera. I take issue with the characterization of the auto-focus as "poor"; that would seem to suggest that it is unusable, while it clearly is not.

My K-1 routinely accurately focuses on fast moving objects such as aircraft, racing bikes, racing cars, scrambling bikes, etc. They are typically initially moving towards me, then across me, then sometimes away from me, in perhaps 12 frames over a period of about 3 seconds. I typically get every frame sharp. I've published examples of photos & whole bursts in the Pentax SLR forum.

Apparently the K-1 in my hands acts differently from the K-1 in reviewers' hands! I don't know why for certain. But I suspect it is simply that I use center-point AF ("Spot") in AF-C mode, & pan with the subject during the burst. It works!

I realise that reviewers have to test a camera's capability for all sorts of shooting styles. I assume lots of people use camera-tracking rather than user-panning, so it has to be tested.

But I feel that the FACT that people who use the same style as me get good results should feature as an extra conclusion of any review. I'm certainly in the target market for the K-1!

The review team are following the DPReview standard method for tests, and they shouldn't be attacked for that.

But that method is delivering conclusions that those of us who routinely successfully shoot properly-focused action with the K-1 find bizarre. It is as if the K-1 in my hands isn't the same as the K-1 in the reviewer's hands.

The DPReview team test each camera's complex AF technology. As a user, I don't use the complexity. If the K-1 had just a single good AF point in the center I would be OK doing my action photography. But such a camera would be laughed out of court!

Somewhere, there is a hole in the review method. It doesn't appear capable of speaking to someone who uses my style of shooting, even though it works. Am I the only one left who uses center point AF? Or are there others who also are not catered for properly by this sort of review?

The reviewers must follow whatever method is current. But I think their current method has a hole in it.

In reply to:

gravelhopper: I do not know if someone else already summed up to what the AF / AF-S discussion boils down - so here is my take: It is irritating that DPRs test procedures makes them dismiss the K1 AF in their conclusion with "poor AF", and in their autofocus section dismiss even the AF-S as failing about half the time - while literally all K1 users are happy with the K1 AF (operating within its limits respectively compensating its limits with skill, see plenty examples on Pentax DSLR forum).
This should raise questions: if (a) either DPR test procedures do not match how real world K1 users apply their K1 or (b) the K1 users are plain stupid to not notice their failing AF.
Plus, it remains to be asked if DPR used a faulty body / lens: I have never heard of or used a Pentax AF-S failing about half the time (no matter if center point, border point or auto).
Regarding AF-C and tracking: for me no doubt here, the Pentax implementation is miles behind what other manufacturers deliver.

I shoot action, I rely 100% on accurate AF, and for me the K-1 is very good. I can routinely shoot a 12-frame burst of a racing car heading towards & across me, every frame accurately focused. (I've posted such bursts in the Pentax SLR forum).

But my shooting style appears to be different from the style that DPReview tests. I mainly use center-point AF. I point the center of the viewfinder at the subject, press & hold the shutter button, keep the camera pointing at the subject as it moves, & release the shutter button when I have enough. (I use the latest Pentax FF lenses). The K-1 has no trouble with this.

But a lot of the emphasis of the K-1's review was on other shooting styles, such as using lots of AF points, perhaps letting the camera instead of the user do the tracking. If lots of people shoot like that, they HAVE to test it.

I think they should place equal emphasis on all valid styles. But the summaries & conclusions falsely give the impression that NO style works well.

Marty4650: So this is essentially a Nikon D810...... only a little bit better, and selling for $1,000 less...

Sounds like a dream come true for Pentax users.

villagranvicent: Whether the twist LCD is a gimmick or not depends on whether it is useful to the photographer.

Having used an articulated LCD for the first time with the K-1, I wouldn't buy a system camera without one! The most important part is the hinge. But the 4-leg feature is a bonus.

I've use the articulated LCD so far for: ground-level Live View; over-the-crowd Live View; Live View on a tripod lower than eye-level; using "Info" and "Menu" in a variety of situations, especially but not only on a tripod; convenient reviewing of photos with someone else.

(Until I had it I didn't realise how useful it could be!)

Ptitboul: I haven't used it "in the field" yet.

I've done tests that convince me that, while I can actually fix the vignetting in post-processing, I have better things to do with my time, and so I should either fix it or reserve it for (unlikely) cropped uses.

The point is that I have all 5 of the recent Pentax FF zooms, so the 60-250mm would need a special role. And the main one for me is "much lighter, even if slower". That role is relevant for action, but not really for portraiture.

In reply to:

tassosDA: This is a good and honest review. I really hope that Pentax will work hard to improve it's AF system and make it compare with best in class, and NOT with previous generation Pentax AF!! Basically its the last point of criticism (together with video specs) of an otherwise excellent camera...
Com' on Pentax, give us top notch auto focus...

tassosDA: embarrassing for whom?

I ROUTINELY expect with the K-1 to get an AF lock on an airplane or racing bike or car heading towards me and across, then keep that lock for (say) 12 frames over 2 or 3 seconds. See:
http://www.dpreview.com/forums/post/58014853
http://www.dpreview.com/forums/post/58016080

I'm bemused by anyone who CAN'T do this with the K-1 plus the recent long FF lenses from Pentax! What is the difference? There is currently a lot of puzzlement among those of us who have successfully been shooting action with the K-1 for the last 2 months or so about why reviews say what they do,

Obviously I'm not saying reviewers are dishonest. Nor are they incompetent. But I suspect they are using the camera in a way that I would find alien, so certainly I could not rely on such reviews to make my own purchase decisions.

In reply to:

SungiBr: Nice review. But sad to read the poor AF performance.
I was expecting a better performance, at least, with single shoot and dark environments, because previous bodies aren't that bad.
Maybe it's a buggy firmware, as the system is claimed to be, at least, better than the K3 (wich you DPreview guys reviewned and it didn't get that amount of failures).
Maybe that better Pentax AF system will come with their next APS-C flagship...

SungiBr: I'm puzzled about what they wrote. I can ROUTINELY shoot a burst to follow an aircraft or racing bike or car, get a focus lock rapidly while it is some way away, then keep that lock for seconds while I get (say) 12 in-focus shots and the subject is large in the frame.

I showed examples at the following:
http://www.dpreview.com/forums/post/58014853
http://www.dpreview.com/forums/post/58016080

For some reason, what is routine for me (and some others) doesn't make it into reviews. Why? I don't have a magic technique - I point the camera at the subject, press the button, follow the subject during the burst, then stop when I have enough. It simply works!

I suspect that the reviews are testing a different action photography style, where it is the camera rather than the photographer that is following the subject. That is alien to me so I can't comment about it.

maljo@inreach.com: A nice camera but a bit late to the party.

villagranvicent: they released 5 new FF zooms, 4 of them pro-class, over the last 14 months. (I have all 5). They have a roadmap with 5 more FF lenses.

What this suggests to me is that they have made a strategic decision to go for K-mount FF. That doesn't itself decide whether future cameras will be SLRs or mirrorless. That is a separate matter.

Perhaps they will go for K-mount FF mirrorless cameras as well. (They know that lots of people prefer SLRs to mirrorless, and vice-versa of course). We don't know yet.

There are 15 Pentax "official" FF lenses in their current (June-2016) lens line-up. 5 are zooms released at intervals over the last 14 months, from 15mm to 450mm. The rest are primes, from 31mm to 560mm.

I personally have 7 Pentax official FF lenses from their current (June-2016) line-up. 5 zooms from 15mm to 450mm, plus a couple of primes. I also have a Samyang 24mm tilt/shift. Plus some Pentax "unofficial" FF lenses (that work at FF but are not officially listed as such).

I am currently working out which to get rid of, because I have too many.

I used the K-3-series a lot, and the (wonderful) DA* 60-250mm a massive amount.

Now I use the K-1 and D FA 150-450mm for airshows. The main problem is the weight of the lens! Otherwise the image quality is higher.

I expect to remove the baffle from the 60-250mm to reduce its vignetting on the K-1, to have a slower but lighter and more manageable lens for slower moving aircraft.
