In reply to:

DeathArrow: You tested Autofocus using a slow focusing lens. Part of why Pentax does poor in AF test is because it doesn't have fast focusing lenses.

The only fast focusing lens is the new Pentax-DA 55-300mm F4.5-6.3 PLM WR RE. To better assess the capabilities of the system I think you should use that lens.

200mm at F2.8 is not an easy test. I have not seen any other camera tested with such setup at DPR except K1 and Kp.

Mirrorless cameras with short flange distance are great for consumers who can adapt all sorts of legacy lenses to use on them. I am guessing not enough m43 camera buyers buy native m43 lenses, hence resulting in Panasonic's hesitation to invest further in the business.

Roland Karlsson: I have to say - I do not like the interchangeable grip. I would absolutely always use the biggest one, and really would like an even bigger one for a deeper finger grip.

Doing so, then the meager battery life would be solved.

Hey smart people out there, time to make a larger Kp grip that some people prefer, or even custom fit to user's hand shape. If you like to tip me for the business idea, you're welcome to do so :)

Hellraiser: Pentax,
Please make a lighter DSLR. You managed to do it with K-S1 we know youcould do it with another or just put K-S1 back on the market.

Did you buy a K-S1? How much are you willing to pay for new K-S1?

In reply to:

jaxson: Video Stabilisation is utter rubbish in my experience. Warps the image in a non linear way which can't be recovered in post software. Definitely not real IBIS SR being used here.

FYI if the stabilisation option is called "Movie SR" then it's not real sensor shake reduction. Pentax had this working on the K-x / K-7 and K-5 models, but walked away from this, right when it was the next best thing from Panasonic, Olympus and Sony.

"Thankfully, the also features 'Movie SR', smoothing the shake from shooting video handheld. We aren't certain if the stabilization in movie mode is electronic or if it uses the sensor's stabilization or a combination of the two, but the result is impressively still handheld footage."

I don't think so.

Sensor based video stabilization will come via firmware upgrade for K1 and Kp later, according to pentaxforums interview of Ricoh staff.

Dear DPReview, did you test any other brand's camera with 200mm lens at F2.8? I do not recall Sony or Fuji or Olympus cameras have ever been subject to as difficult shooting setup for auto-focus test at DPR.

In reply to:

Josh Leavitt: It would be cool to see Pentax release a monochrome version of the KP, assuming their noise-reduction algorithm would work without a color filter array. Monochrome sensors theoretically can achieve 1 to 1.5 stops more in native ISO than conventional Bayer sensors.

I doubt it will happen though :(

How about BW conversion of pixel shift images?

illumidata: Wow, 1100+ posts and rising.

That sure was some quality bait...

Still a ways off the 2659 comments for the K1 review.

Look here where I compared 645z vs A7Rii vs K1 pixel shift vs D810 at ISO 51200 using DPR's studio comparison tool:

https://g4.img-dpreview.com/D8FC3ED3029F488C915DF9C073D892AE.jpg

Besides K1 pixel shift being cleanest, 645z still has edge over A7Rii, and D810 is last.
You can do the comparison yourself quite easily to see if MF is worth it for your usage.

In reply to:

Karroly: Why is the D FA* 50mm F1.4 much bigger than the SMC FA 50mm F1.4 ?
Built-in AF motor ?
Additional glass elements/groups to improve IQ ?
OIS ?

From what I gather, to achieve across the frame sharpness that many demand of modern lenses, larger glass is needed.

@Ian, What did you expect? Everyone takes pictures of this same planet we all live on, repetition is bound to happen.

I see nothing wrong with post processing to one's taste to achieve the visual impact one wants. You don't think Ansel Adams tried many ways to dodge and burn his photos to achieve the image he desired? Taking a photo on a negative (film or digital) is just the first step. You can interpret the "image" in many different directions with the post-processing methods you select.

Richard Schumer: I owned an Asahiflex I, which I bought used in 1957, when I was 14 years old. The slow f:3.5 lens wasn't fast enough (this in the days before Tri-X) for available-light shooting, so I traded it for a Pentacon with F:2 Biotar, and found the eye-level prism finder much better than either the waist-level reflex finder or the eye-level optical finder without focus aid of the A'flex. When I visited Japan in 1966, I bought a black Spotmatic with its f:1.4, 8-element "radioactive" lens (wonderful!) and used it until the K-mount was introduced, at which time I traded it for an ME. That kit was stolen, so I tried a Nikon F, but it didn't feel as well-made as Pentaxes nor did it fit my hands as well. After a few years, I traded it for another ME, which I used until the *ist DS was introduced; that was replaced by a K10D, which I still use. About the same time, I acquired a 645 with four lenses for film use.

I guess that makes me a long-time Pentaxian!

Happy 60th anniversary!

In reply to:

Nikita66: DPR: The article lead mentions 'compact' and 'mini' and yet I still don't have an idea of the size. None of the pictures help. What would help is a side by side with a well known Canon or Nikon entry level APS-C DSLR.

Further, you don't get to the price until the 14th frame. Yeah an Amazon price is listed above, but I can only assume that's the MSRP.

So annoying the basics are buried so deeply or ignored in a new product article.

Kp is not entry level. It competes with Nikon D7200.

In reply to:

Couscousdelight: The question is, why would i buy this camera instead of a K3II which cost 900$ ?

Richard, high ISO improvement was relayed by Imaging Resource based on Ricoh's claim. I'm keeping an open-mind to see if IQ between KP and K1's ISO 51,200 indeed are close as Ricoh claims. Sony does not always get the best out of their sensors due to different post processing algorithms.

Reasons that I prefer KP to K3-ii:
1. Better high ISO performance (to be verified)
2. Tilting LCD (better than articulating for street shooting)
3. Improved AF (to be verified)

If I can get comparable IQ of my K-S2 at ISO 3200, with KP at ISO 12800, I will probably skip upgrading to FF.

tassosDA: Light bug, if this is the case, than it would be a first for Pentax!! Selectable af points via touch screen?? That's huge man!!

I hope that's the case. So far only DPR reports a touchscreen as part of KP's spec. Even Ricoh's own official spec. has no mention of touchscreen.

In reply to:

anu l: KP cannot be a replacement of K-3 II, it has no top LCD, uses a weaker battery found in K-70, probably uses inferior & louder shutter mechanism found in K-50 & K-70, has no decoupled AF-L , AE-L buttons, has no GPS and seems to have a more composite body than a robust metallic body of the K-3 II.

I have never used the top-LCD for any purpose when I handled K20D, K5. Looking through viewfinder gives you same information, and you don't have to take you eyes off of the subject. I mostly use back LCD for exposure or other settings information.

In reply to:

anu l: It has too many omissions fro the K-3 II and hardly any new serious features (AF improvement etc), hence making it overpriced.

According to image-resource's preview, KP's high ISO performance has improved, and there is some improvement in AF algorithm. Overpriced compared to what?
