yoms: Can you shoot Dual Pixel Raw file via the OVF or is it mandatory to use LiveView?

Once you have processed the DPRaw file in DPP, do you still have a 30 MP Raw file you can later import in Lightroom? Or do you end up with Tiff or Jpeg?

Thank you for your reply.
So the only option to keep LR is hoping for Adobe to develop a specific DPRaw engine. Well... I'm not so confident about this.

Hi DPR team. That was the test I expected most for these new Nikon bodies.
Would you say that once this is performed, focus accuracy was always spot on?

How about getting rid of this AF fine tune altogether? For instance for Canon and its Dual Pixel tech, how convenient would it be that on half-press auto-focus is performed as usual and then on full press mirror goes up and Dual Pixel is used to fine-tune focus for the specific selected AF point before taking the shot? Shouldn't be too time consuming I guess since focus is already "close".
Do you see anything against such a method?

Thank you again for this!

yoms: Hi!
Can someone explain me something about the 3 shots of the distant clock to point out focus inaccuracy?

As the clock is really distant, I guess focus is set on infinity, right ? Moreover, focusing and exposure is always measured the aperture fully open, that is 1.4. So why is there misfocusing? Infinity is infinity, no ? There's no infinity + a little front focus or back focus.

Thanks for explaining.

Thanks again ! This really helps.

I wrongly thought that if there was so small an angle between infinity and the 3m marked distance, it was because there was almost no room for change when travelling from 3m to infinity. I understood something like : "Beyond 3m or so, it's (almost) the same. So why bother having a long distance scale in that range, it won't help/improve things".

So I understand that there's obviously a design choice by Sigma to optimize the focus ring travel distance from 1.7 to 3m. Should be the range they expect people to use the lens most and/or where the slightest change has the biggest impact. So it's the range where there's the most part of the focus distance...

Put that way, it makes sense. Ideally the mechanical travel distance should be infinite too as there is but one 100% perfect focus plan...

Thanks again!

Thank you Andy. I understand that. I must have expressed myself badly...
What I meant is that it seems the clock is so far away that it's way beyond the hyperfocal distance (93.1m @50mm f/1.4 on APS-C). So what I don't get is : if the camera front-focused a little, it should still be within the "sharp focus range". No ? Unless the camera front-focused a lot.

Sorry for bothering...

Many thanks Martin ! You've just answered one big question : how can I put the newly imported photos apart from the processed ones ? The idea of creating a folder named "Import photos" is great. I love the "Previous import" collection in LR to get back to my previous import. Sadly, I often make several imports at the same time that I consider as 1 unique import. But your idea solves this issue by keeping all these photos in one place until I decide to move them to their final destination.

Cheers,
