Well, as a French, yes, it makes more sense for me :)

Couscousdelight: But the K-01 share the same sensor as the K5, which was a leading class camera regarding dynamic range, 9 years ago (14.1EV accorded to DXO Mark).

Ok, got it. I was thinking that it benefits for video capture too.

If you want to know more about the concepts & philosophy behind those lenses, check this article from a Japanese photo magazine translated in English :

No, you just don't know.

(unknown member): wow. 1899 usd / € 1999 for a non-stabilized, tiny niche brand DSLR-only 85/1.4 in 2020. some people really must have too much money.

Meanwhile the excellent Canon EF 85/1.4 L IS works flawlessly on mirrorslappers as well as mirrorfree EOS R bodies and can be had for about € 1300 after cashback. or one can pick it up in hardly used mint condition or a Canon EF 85/1.2 L II for well under a grand.

Pentax ... a value proposition. not.

" the excellent Canon EF 85/1.4 L IS".
When i see how a vintage Pentax 85 F1.4 compares to the modern Canon 85mm f1.2 L mkII, maybe Canon could learn how to make a sharp 85mm from Pentax :

In reply to:

toomix: it is an excellent travel lens for the Fuji system. Yes, it is not sharp as primes in the corners (it is in the centre) but who expects it to be?

"but who expects it to be?"

A Pentax user which own a 16-85mm f 4-5.6 lens maybe ?
The pentax cost 500$ and explodes the Fuji in terms of sharpness & rendering.

In reply to:

Mistral75: > it claims is the smallest and lightest autofocus lens for a medium format camera.

DPR's statement is incorrect. The smc Pentax-FA 645 75mm f/2.8 is smaller (74.5mm x 37.5mm vs. 80mm x 47mm) than the Hasselblad XCD 45P and also lighter (215g vs. 320g).

Hasselblad's claim is 'the world’s lightest digital medium format autofocus lens on the market today.'

The word 'digital' in their claim is important since the smc Pentax-FA 645 75mm f/2.8 is (i) lighter and (ii) a medium format autofocus lens on the market today. However, it comes from the film era.

"Lenses with built in focus motors are not AF".

This is ridiculous.

Couscousdelight: 1 year ago, i was looking for a UWA prime lens.
I was very interested by that one, it had everything i was looking for : sharp, small, well build...
Then, i read a test of it with pics made on a sunny day with the sun in the frame, and, it was awfull. Flare resistance of that lens is just terribly bad, and it didn't suit my style of photography, (contre-jours with the sun in the frame).

I finish with a Irix 15mm, which is cheaper but also bigger, it have some flare problems too, but only when the sun is exaclty on the center of the frame.

Too bad for the flare, i was ready to go with Laowa.

@Waffen :
You're right, i've made a mistake, it was the 12mm f2.8.

Lovely lens.
I'm not a Canon user, but i really enjoy their UWA lenses, like the 11-24 f4.
They are surely the best UWA lenses avaiable out there.

duchamp: Even though the movie was shot on gh5 strangely m43 weren't included. The Panasonic G90/95 for example has all the pros of the ZA50 and doesn't have its cons.

This is stupid. 8K is stupid.

Our vision resolving power doesn't allow us to see details with such resolution on moving images.

Avatar was considerer as a visual achievment. It have a 2048x1152Px resolution in theater, and no one have distinguished pixelisation or a degraded image.

Why not the K-1 ?
It's maybe not like a last tech camera, but it's a marvellous tool for landscape photography.
Pixel Shift, astrotracer, rugged body with a cheap price.

And dealing with the A7RIVs difraction above f4, what a joke.
