mkochano: Polish black friday prices for bodies seem to reflect DPR findings:

A7 III: 6789 PLN / 1805 USD
Z6 II: 9999 PLN / 2658 USD (+47% to A7 III)
R6: 12390 PLN / 3294 USD (+24% to Z6 II).

Although I wonder if R6 is actually almost twice as good as A7 III.

Similar to audio, small performance increase at top level is double price. There is usually some happy medium, or happy high end.

davev8: for 1/2 this money you can buy and old sony 42MP A7rmkii (or a mki as crap AF won't matter and save more) a nice old 50mm F1.4 and get way better results and have a smaller package

Only advantage of m4/3 platform was and is size of platform, nothing else.

There is no magical advantage in performance, simply cause physics do apply. And smaller in photographic world isnt better.

Smaller can be "good enough" which in many aspects m4/3 platform is. But if you want most performance for your money, its not a system you want.

m4/3 system often defeats itself, especially when it starts to go to fast lenses, cause its a bit against that "small and light". Fast lens are big and heavy no matter what platform.

Physical laws are fairly solid thing and they wont change any time soon.

I think m4/3 is perfectly usable in its niché. Trying to compare performance against other systems is a bit pointless. Apples to oranges and such.

Quite surely lens in question will be good for someone. But it will be niché within niché. Not doubt Cosina is aware of that, they are making lens for quite some time now.. Hence the price, I guess.

Zvonimir Tosic: Couple of typos in the article:
Towards the bottom, it should state 29mm F0.8, not 28mm …
Also, every camera is 'a full frame' camera, because every camera comes with the entire sensor designed for its image frame, not partly chopped off. Technically correct statement should be, "an equivalent focal length of a 58mm lens on a 135-format camera". Ta.

Only thing that could do something of half frame (with some crop) was APS-H in form of Canon 1D series.

Which IMHO was actually about best from crop sensors.

Fairly sure you can squeeze FF and very decent 50/1.4 lens into 2100 USD budget.

Think it might be actually interesting lens for video crowd..

Sufferfest: Congratulations!
These are all good and lovely landscapes.
Great inspiration for the rest of us.

Also, once again we see the myths of FF and lots of MP needed for landscapes debunked. Many of these prove that’s BS. The D3200 even today is extremely capable for example.

Probably not, D3200 is 24 mpix aps-c. That pic, while beautiful at web resolution shows quite a lot of noise under closer inspection (I mean apart intentional JPEG compression).

It can do decent pics at ISO 100, if there is enough light, preferably a lot of it.

Once you start processing it, you need to be careful, cause those files crumble very easy.

There is a reason why it was low end "starter" camera.

Sure you can make decent pics with it, apparently even win contest, just dont expect it to hold much together at pixel level.. or at some reasonable zoom level. Cause as long as you PP a bit, or in case of winner a lot, then it just wont be that great for close up inspection.

You dont need FF with 50 mpix or MF with same or more. But it definitely helps to have them, when you want files that can be properly tortured in PhotoShop (or whatever you fancy). Low noise floor MF with not that much pixels and 16 bit is perfect for such things.

But you need to know how to shoot. :D

Kryojenix: Does anyone know a good offline software for encoding HEIF and AVIF images in at least 10-bit? Darktable doesn’t seem to do it yet...

In color case, 8bit isnt problem. In BW case, 256 steps actually is a problem. And yes, you can see it.

In general, doing BW prints is rather difficult. I would very much like camera that could do 16-bit BW images.

Crypt Keeper: The future of photography will surely combine image acquisition+3d spatial scanning + AI to produce a photo from a perfect textured hi-res 3d model or 3d scene.

Imagine the possibilities. Take a shot and choose the camera viewpoint later. Or rotate the target to taste. Let AI to take care of resolution, sharpness, color and noise.

I doubt the camera players will have the courage to make the move. (after all, who will need to buy lenses when AI can take over any poor image and produce the result you want and even more)

The "move" will likely come from smartphone makers. And then traditional cameras and lenses will become museum objects or collectors items.
But we are not there yet. Maybe in this lifetime...

It does not.

Internet really is good in killing society (and its today anti-social actually). But its just a tool as many others, that only propel humanity to do what they do best. Which is harming itself in large scale.

Which again, is nothing new.. Mankind reminds lemmings.

Debankur Mukherjee: What is "Large" medium format 50MP 43.8 x 32.9 mm CMOS sensor ?

Its bigger than average, sadly not enough.

58x58 would be nicer.

Difference aint that huge, unless camera can actually resolve 14+ bits. Which while many claim to have "14 bit raws" still very few actually fill those bits.

Well, he more or less gave us visual side of everything that uses displays today.

Reactive: And to think modern GPUs divide squares (quads) into triangles (tris) to render them quickly... I wonder where we'd be now if we'd had triangular pixels from the start?

Well, we can raytrace dots now in real time. Not bad either.

SandySandy: I am curious why digital photography didn't make it to mainstream much earlier. Apart from Kodak's now infamous stupidity, I guess technology was delayed, maybe to protect analogue stock?

It was about hardware. If you ever saw early digital cameras you understand how uncomfortable it was compared to same day analogs. Not mentioning sensor/film size.

Jones Indiana: If not legit firmware, then this means the code is out somewhere.
But it would also imply that one person can do a lot of harm with injecting and implementing malicious software. Let's say a random countdown timer that after the clock expires bricks the lens.

I would not update firmware from an unknown source.

Cause they do that, its that simple. I wouldnt do that if they werent such greedy a holes.

Fairly sure Apple never heard about this one. :D

Mescalamba: I would perfer performance that can be measured.

Mostly something about 14 or more bit RAW files preferably with as accurate colors as possible. Cause last time I checked (and only reason I dont have Pentax) was pretty low quality CFA. As long as competition has higher quality CFA or better "tuning" of colors (Canon lately seems to be rather good) then I kinda cant find reason for Pentax.

Also lens could use a bit of pick-me-up.

It does exist and its most likely same as in Nikon counterparts.

Nikon definitely doesnt use same CFA as Sony, despite using their sensor. Given numbers for Nikon and Pentax are rather close to each other, I think its same.

Also makes sense simply cause Sony wouldnt be so generous to give their competitors same quality for same price..

CFA can drastically reduce price of sensor package. Probably enough so Pentax/Nikon can build around that sensor stack and still make money.

@dpthoughts

Color accuracy of CFA isnt tied to color profile, its independent metric. Color profiles just shift colors around, they cant provide extra color clarity. Either CFA does its job or it doesnt.

Color profile can help a bit, but it wont make camera see difference between colors that it just cant see due CFA.

CFA is made to spec probably by Sony. Specs are Pentax doing, most likely based on how expensive/cheap it is. CFAs are not cheap at all, rather opposite.

Also higher grade CFA has some negatives, like loosing a bit of light, thus more noise can possibly pop up. And ofc that price. One of reasons why Sony lost quite a few money on A850 and A900 was that CFA itself was really expensive and if they didnt cripple it in way they did RAW processing in camera, it would be probably one of best color cameras. Since they did, one of best is 1DMK3 along with 1DsMK3.

Since then very few cameras reached some decent level of color quality..
