On Pentax K-3 II added to studio test scene comparison article (177 comments in total)
In reply to:

photoaddict: Wow, the pixel shift version does definitely show a huge improvement in resolution compared to normal version. Reminds me of Foveon images.

Please select "pixel shift" in drop menu to compare against normal images if you overlooked. I noticed some of you complained there's no difference.

I noticed the RAW file is massive - 123 MB for a pixel shifted file. Eeek!

Interesting, a Foveon tiff is about 120MB. I guess all that information has to be stored somewhere. Doesn't Silkypix convert the raw to something smaller though?

DPR, Thank you for including K3II pixel shift in the studio test scene. It looks like an excellent feature under limited circumstances (some product photography & maybe architecture). As technology is always evolving, I look for Pentax to possibly include this feature in their new FF camera this fall and subsequent models of the K3 might have hand held pixel shift or even moving subject capable PS. Won't those be interesting to see.

Interesting sensor technology. Sony will debut it in this model and, if it works out well move the tech up the line. The price might cause many to pause, myself included.

On Nikon D750 service advisory warns of shutter issue article (341 comments in total)
In reply to:

dholl: high-end Canons are "made in Japan". high-end Nikons are not.

I believe this fact bares further investigation as there lies the answer to Nikon's problems.

Right about that. Also, their shutter assembly are probably not manufactured in the same place as where the body is assembled in any case. I needed an excuse to go handle one in a shop, thx. :)

D810 is manufactured in Thailand according to most internet sources. Not that I think this matters much unless a given factory has a lot of QA issues that can't be resolved.

Buttons252: I have never owned a canon camera nor want too, but these scores are a pile of rubbish. I have used 5d mkiii and 6d for paid gigs. Borrowed a rebel T3i to compared against my Pentax K-X (long time ago). Each time ive used a canon i have been impressed with its output. Not just in the quality of the photos which were excellent but their whole system -- flash, lenses, autofocus and knock on wood -- no failures. They are good cameras that will get the job done.

Interesting you mentioned the Kx. That was one of the first Exmoor sensors employed by Pentax wasn't it? Hot stuff in its day.
I used Canon 6D for the last three years, no complaints, so I agree with you regarding most situations.

Interesting article. I enjoyed reading it.

On Canon EOS 5DS / SR First Impressions Review preview (3413 comments in total)
In reply to:

Lassoni: Remember how 1DC got a massive price drop couple of months back or something? That must've tore the pants of existing owners, seeing value of camera drop by thousands in one night. And how sony is coming with a a7r2 that can do pretty much the same thing, but for much cheaper? Oh god, canon is doing bad.

It's true if you're not an early adopter. I got a great deal on an A6000 for waiting and Sony released a FW update right after I bought. That was a winner for me. I haven't done so well most of the time though. Lesson learned.

In reply to:

moga: All in all these new Canons are not bad by any means. While I wouldn't buy any of them I know plenty of fashion and studio photographers that are interested in a 50mp sensor. Not everyone can afford medium format and a sensor like 60 mp in the PhaseOne digital back its not much better.

Pentax 645D 4200$, 5DSr 3900$.

Do you mean A7R2 will be 1/2 the price it is now in about 18 month? You might be onto something. But they all depreciate now. Closer to throw away consumer electronics than cameras of the old days. But still pretty cool.

Horshack: "MW: We wanted to overcome the idea that has been prevalent since as long as there have been digital cameras, that you can have one virtue [resolution] or the other [sensitivity] but you can never have both. Look at the Canon EOS 5DS. A maximum ISO sensitivity of 6400, and crippled movie capability. Canon says that it intentionally created the camera to fit the requirements of certain photographers, and [has thereby demonstrated] that the material science of their device technology [cannot] accomplish both objectives."

Removing any doubt that Sony is gunning for the 5DS/R. That and the fact that they announced the A7rII and its fast EF-lens focusing ability just two days before the 5DS/R preorders started shipping :)

Yes, that's the model they're competing with.

Thank you for the interview, DPR.

Petroglyph: Ricoh's website reads 19 elements in 16 groups so we'll see if the formula changes. Also Pentax has been putting larger front element than normal perhaps the 77 cap will change to 82. My guess is they will time it with the FF release more closely.

Front element now tilts so the LCD don't have to?

In reply to:

Mister Joseph: I wonder if it can AF with Nikon and Pentax lenses too (with an adapter of course)?

Ah, I see their marketing claims improvement with the Metabones adapter for EF lenses. It could be true. Does anyone make a similar adapter for F & K lenses though? Those would be hot sellers are you listening Metabones?

The adapter would have to be chipped and pass through electronics like the Metabones Smart adapters for EF lenses. AF is slow to non-existant with this type adapter. Now if Sony made an adapter...

I noticed the specs say Raw (ARW 2.3) any significance to the ver 2.3? Compression changes, for instance.

Petroglyph: Wow! Is all I can say about this upgrade. IBIS, Better shutter, EFCS, BSI sensor, 4K video. Lossless raw option? I'm looking... What a camera!

I'm certainly impressed it must be quite a sensor.
