PabloSRT8: And what about Red?
RED Helium 8K DxOMark Sensor Score: 108

They apply NR to raw file. That will increase Dxo score artificially. There is no logical reason to believe that smaller sensor in Red cameras is superior to larger sensor in FF cameras. That's a claim that contradicts physics. I call it BS. The score isn't real.

falconeyes: What is this road? Fantastic, must go there!

Anywhere in Himalayas (north Pakistan, north India, Nepal, Bhutan) will have similar roads and scenery.

You can take multishot shot images with D850 in burst mode and stack them together in photoshop and get the same benefits. Doesn't mean anything.

D850 has better image quality (higher DR) where it matters, regular everyday usage, which is single shot images.

Stop posting nonsense, dude. There is no difference. It's stacking multiple images. Same thing that Olympus and Hasselblad do. The only difference is that Olympus creates higher resolution image and Pentax downsizes the final result to original size. You can do the same with Olympus final image: just downsample it to the original size. You will get higher resolution image with less noise, more dynamic range and more resolution and less moire.

As regards to your second paragraph regarding AA filter and sensor-shift, you are confusing how Pentax uses sensor shift to mimic AA filter (which is a different topic. It is not a multishot mode -- the images there have lower resolution, and there is no noise or DR benefit like in multishot mode like you see in this studio shots).

If you don't understand something, don't google it and come back here posting confused nonsense.

No, it doesn't take $43,000 medium format body to best the K1. Both D810 and A7Rii have better image quality than K1, according to dxomark. They also have superior AF and are faster according to DPReview.

Don't post nonsense.

Pixel shift isn't imaged quality test. It's stacking multiple images (you can do it with any camera using photoshop) that requires a tripod and still scene. The cameras take multiple shots and stitch the images together. This isn't an invention by Ricoh. Olympus and Hasselblad both did this using IBIS on their cameras before Pentax.

You can also do the same thing with any camera using Photoshop (take multiple shots and stack them together for higher resolution and lower noise).

Here is just one example

https://petapixel.com/2015/02/21/a-practical-guide-to-creating-superresolution-photos-with-photoshop/

The topic of this thread was AA filter on 5D Mark IV. What do all these posts about pixel shift on K1 have to do with the original topic?

Didn't last long. Google pixel 2 beats both by 4 points.

You don't need Pentax K1 in pixel shift mode to see the scene. Use the reference camera Phase One IQ180. That's a benchmark camera and why it's there, so other cameras can be compared to the benchmark.

Pixel shift has a very limited practical use, and requires a tripod, and still scene. D850 is a far more versatile camera.

It's moire, not extra detail. So Canon looks better there.

Wubslin: Funny thing. For much less that the $1700 asking price I can buy an SLR and a perfectly good wide-range zoom.

Newsflash: I can use other lenses with an SLR too. And it also has phase-detection AF. Just imagine that.

SLR with lenses doesn't offer the same convenience for people who have no time to carry a bunch of lenses and change lenses in the middle of the trip. It's surely isn't the same thing.

ET2: That's why medium format cameras don't need 16 bit. It's just waste of space and marketing ploy. Some like Pentax 645D don't even need 14 bit, as they have low DR sensors.

no, A7s doesn't need 16 bit at base ISO

justmeMN: DPR has an article about Sony's positive financial results, but didn't say a word about Canon's previously announced positive financial results. And DPR wonders why some people think that it has a pro-Sony bias.

"This is because Sony has had a prolongued period of poor results a"

Not true as Sony camera division has not been negative in last 7 years. It always made money at least since 2010.

Majauskasson: Nice ad for Sony but resolution C+. You'll see this clip on their ads soon. Any half decent camera will do the same. Sony outbid Nikon and others for the rights and NASA can use the cash. Let's remember the NASA LRO circling the moon at 25 miles up photoshopped the non-existent fake Apollo landers in to keep the gullible Apollo nuts happy. If you believe the blobs are landers remember that amateurs with backyard telescopes got excellent resolution too. DP has shown these. NASA has been and still is scamming the world. It cancelled the manned Mars mission because it "can't protect astronauts from space radiation". Well, what about Apollo? How did they manage it? Using 1960s technology then it was no problem - 6 men to the moon in 3 years. Now with powerful computers NASA is stymied. Space is tough. NASA lied and created a fantasy Apollo story many believe to this day.

Please take your medicine.

IdM photography: Times are difficult if you need to invest today in a new system...
Will you choose to buy a DSLR, knowing that the future is mirrorless (with advantages related to size, weight and better lenses...)?
Or will you buy Sony Mirrorless, with a current range of lenses that may not cover your needs?
I think that Sony caught Canon and Nikon by surprise, with such a capable mirrorless camera... Neither Canon nor Nikon are producing any FF mirrorless camera...

IdM photography, all Canon EF lenses only need electronic contacts for the aperture control and autofocus. They don't need mechanical levers in the mounting mechanism. Not all Nikon lenses have that.

EF mount was introduced in 1987. Nikon F mount is much older.

What lenses have you tested that don't work properly? On A7RII some lenses were even faster than on Canon cameras. A9 should be better. Is it 10 fps with Canon lenses? If so, that's still fast. Does it do 20 fps with Canon lenses with AF fixed on the first shot?

Let's not forget all Cannon lenses work on E-mount cameras, including AF. So A9 has its native lenses, plus A-mount lenses, plus Canon lenses.

Triplet Perar: On DPR was published a rumour that Ricoh is thinking into shutting down camera business "because of the losses". DPR published Ricoh's reply too, but went no extra mile, no extra 20 articles to dig more, see what is going on, because, imagine!, DPR may fear they may loose some valuable audience? Does DPR care about users of Ricoh's and Pentax cameras that come to DPR?

But there is TONS of coverage about one camera from one manufacturer. How disproportionate is that — care about one single product vs the future of an entire manufacturer and majority of their products?

That is one example I used to state DPR lost balance and reporter's cool. So instead of DPR, users of Ricoh Imaging's equipment must dig more, investigate what is the truth. In Ricoh's latest annual report, camera business division marked increase of sales (!) in fact. And, Ricoh is to repurpose some compact cams plants, and that is shown as cost, of course. How that squares with words in rumours? Who cares for truth?

"Triplet Perar: Are you OK"

Was he ever? He has been this way for past 10 years since I have seen him around. You should read some of his K01 comments. An amazing camera according to him which was the only profitable mirrorless camera because people at Ricoh are genius. They didn't invest in new mount and made tons of money by doing no R&D by being geniuses. All other fools (like Sony and M4/3) lost money, said Triplet Perar. He said that. A dozen times. He was using a different username back then.

For anyone who doesn't know, Triplet Perar is a long time Pentax fanboy with various IDs over the years. He thinks a rumor about Ricoh shutting down their camera business and a major flagship FF camera with new features (first mirrorless cameras to compete against Pro sports DSLRs) both should have an equal amount of articles. Weird

Triplet Perar, why be so jealous? Don't worry. Ricoh will release a camera with good AF in 2117 :)
