yoms: When shooting through the viewfinder, is face detect option available in all AF modes?

If I use "Single-point Spot AF" for instance, can I enable face detect so that the camera automatically select the AF point closest to the face? Would be time saving.

@tr573 Thanks for the info. Anyway, my only purpose was to instantaneously move the single-spot AF point the nearest possible to the face just to avoid having to travel from one side of the AF area to the other using the AF joystick. Then, I would have fine-tuned. A kind of "jump-to-face".
But Carey's idea may be a viable workaround!

Thank you again.
Assuming my previous focus point in "Single-point Spot AF" mode was at the bottom left (previous photo), I was merely hoping that with "Face Detection" enabled and a face present on the top right of the frame, the camera would automatically set the focus point there.

I know, in "Single-point Spot AF" you're the one supposed to do the selection job, but it would have saved time not to have press the AF joystick several times to reach the top right corner from the bottom left's.

Maybe there's a viable workaround with what you suggest Carey.

Thanks for your input again :)

yoms: Thank you for the quick review of the 5D Mark III. It has just landed here in France :)

As a main one-shot AF shooter, I would have been interested in more details about focus accuracy, especially with the 5 dual cross-type AF points, rather than tracking.

Would you say focus is so accurate using one of these 5 points that it's mirrorless accurate? I would consider using them all the time, albeit at the expense of cropping/reframing in post to place my subject where I wanted initially to be, if I'm sure focus will be eye-lash accurate almost all the time.

Don't really care about tracking actually...

Hi Carey!
Actually I hadn't much hope someone from DPR would answer me, so that's both very nice of you and appreciated.

I used to shot portraits with 5DIII + 85mm 1.8 + AFMA using corner AF points (I thought composition), but hit rate wasn't that good. I think I almost never shot with the central AF point.

With the extra MP count on IV over the III, it gives room for cropping and reframing the subject. However, I think it's a "sad" method. Would have preferred to have my composition done at taking the shot...

Thank you!

When shooting through the OVF, do you think a firmware update could fine tune the AF using Dual Pixel AF ? Is this something Canon would likely provide ?

1) Half press => Phase AF according to selected AF point
2) Full press => Mirror goes up, sensor is exposed and before taking the shot Dual Pixel AF would fine tune the AF (not time consuming as it was almost there thanks to step 1)

This obviously requires electronic 1st curtain. You can imagine a new slider in the AF menu to set priority between "speed" and "wait for complete Dual Pixel AF confirmation" + an option to toggle this behavior on/off.

I don't see the penalty here. The tech is there, everything is already in the camera. So what's preventing Canon from doing this? Dual Pixel AF seems so good, why not make the most out of it even when shooting through the OVF?

Love shooting through the OVF. Only reason I don't switch to mirrorless...

In reply to:

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...

On article Lightroom Photo Import (117 comments in total)

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,
