Pretty touchy for such a supreme being...

played with G9, the C-AF doesn't lock before doing a bit of hunting. and in low light it's even more obvious.
But Leica also use CDAF and their lens are tuned for CDAF... So it that the reason why Pana went the CDAF way?
well you don't get everything in one package. Canon has great DPAF but they have a crop 4K.

@MILCMan:

"nothing worse than an m4/3 owner who doesn't know how his own cameras work.."

Disagree, as you've just demonstrated.

Just doubling down on the stupid and being offensive still won't help you understand how DFD works.

You really think RB doesn't know what he is talking about?

The only reason there are no FF DFD lenses yet, is because Panasonic hasn't analysed their characteristics and put them into the camera firmware. Same with m/Zuiko and Sigma lenses.

Which is how the old 100-300 lens magically became DFD capable on bodies from the G7 onwards - nothing to do with the lens itself.

"dfd is a fail... there aren't any existing ff dfd lenses that I know of, and no dfd-capable adapters."

What a load of rubbish. DFD is nothing to do with lens or adapter capabilities; it is due to the camera knowing the behaviour of the lens and being able to interpret what it knows to figure out focus. The camera body has a database of lens characteristics; the same characteristics are also available from the lens itself (so old bodies can work with newer lenses)

Wow, so many bad composites. Why do people feel this is a good idea? Please explain.

Really, this is astonishing. (I mean, the responses here). There's a lot of emphasis on focus stacking, which is not what this is intended for.

If you want to do focus bracketing just download the app from the Play Store:

https://play.google.com/store/apps/details?id=de.minaxsoft.gsimplerelease

Full res, RAW and/or JPG, full image control, up to 1024 images per stack.

Then leave this update for what it is intended for - because for focus bracketing it isn't going to be very useful.

CameraLabTester: The algorithm for the procedure is simple:

As soon as the half press confirms the focus, and full press shutter release is made, the lens mechanism rotates 15 steps behind focus and captures 30 frames in 1 second, ending at 15 frames in front of focus. The DOF distance will not be constant because of focal length variations per lens or zoom setting. The key is the incremental rotational "steps" that would be triggered by the "stepping" motor.

There is no patent for this, so other brands would quickly come out with their own updates and software fixes of basically the same thing.

Panasonic was the first to come out with this kind of free firmware update.

.

...contd

This is why Panasonic make such a deal about leveraging DFD, if they were just racking the focus forward, DFD would not be needed. I think DFD speeds this kind of operation up immensely, making it practical to use. The lens doesn't have to change direction during the process, and can deal with the focus points in the optimum sequence, moving the lens in one direction and with the minimum number of shifts.
Racking the focus forward or back with no reference to focus points might make it difficult to manage selection of images by focus point, since there is no per-recorderd (ie in EXIF) relationship.

What absolute rubbish. You are really doing the guys at Panasonic a disservice. Look at the video.

The camera does not move the focus forward as such - it moves the focus in a series of steps so that each of the 49 focus points is covered.

If multiple focus points have the same focus distance, they are covered off together. See the introductory wedding shot, it is pretty clear.

The maximum number of shots is 49 (maybe +1 for infinity?) but will most often be less. Panasonic only ever refer to "multiple" shots, I don't think I've ever seen a number, despite some people referencing 50 images for some reason.

DPR should at least paraphrase accurately. Their description "capture 4K-resolution video at 30fps while shifting focus through the frame" seems inaccurate, both from the press release and the video.

Read the press release that DPR so lazily paraphrased:

Developed with Panasonic’s existing 4K Photo technology, Post Focus not only prevents out-of-focus misshots but also offers greater creative freedom, and is now available via a firmware update for the LUMIX DMC-GX8, DMC-G7 and DMC-FZ330.
Post Focus has been made possible by combining the high-speed, high-precision DFD (Depth from Defocus) auto focus technology and Panasonic’s 4K technology, made possible by the Venus Engine. Burst images in 4K resolution (3840 x 2160 pixels) are shot at 30 fps while detecting up to 49 areas of a frame for focus points at different depths of field.

Note that Panasonic go well out of their way to avoid any mention of video, in fact describing the output as "burst images in 4K resolution...at 30fps".

Seems OK but nothing special - certainly not up to the usual MacAskill stuff.

For something that really is special, and perhaps shows what might have been done:

In reply to:

duckling: While Mr. Pelkowski seems quite well informed and honest, it would be nice to hold a more in-depth discussion on the potential of sensor movement in achieving various photographic goals. For example:
* automatic horizon leveling
* tilt and shift movements
* Z axis travel to focus MF lenses
* automatic panning while the camera is stationary

GoPro have also dropped the ball with Studio, one of the best ways to present video without investing too much time or money.

Template-based editing is revolutionary in this area, but they haven't updated their published templates for years (despite promising to do so) and still don't have any way for users to create their own templates. It is the best way to make GoPro video into something that somebody else might want to watch.

There's a lot of commercial and exposure potential here, just being wasted. For example, skydiving companies could use GoPro and other cameras and very easily slot customers' experiences into their own video, without having to go to a full editing suite.

On challenge Up in the air (11 comments in total)

I'm very surprised by this - if you read the popular sites, it seems like everybody is using quadcopters and KAP rarely gets a mention, but here the kite photos far outnumber the others. They are also pretty good quality - for something that for me resembles "fishing" for photos :-)

I wonder if kite photography is really more popular, or are the quadcopter pilots spending all their time learning to fly and repairing instead of taking photos? :-)

hindesite: Unbelievable. Can people not read the challenge description? The camera is supposed to be in the air, not (necessarily) the subject.

50% of the entries do not meet the challenge rules, which are quite clear.

Looks like you are going to be busy disqualifyin' - even the latest entries have about 50% that don't meet the rules.

Nice photos, but they don't fit this challenge.

Expecting cat photos to show up soon :-)

In reply to:

Mike Oo: I don't understand why he wouldn't use this situaition to prove that iPhones are not suitable for serious photojournalism. Show them what a "real" camera can do. Instead, he shoots the same crap he is about to be replaced with. When I read about his project I was expecting incredible work, owing to his status as a former staff shooter for a major newspaper. Now I see that he is just shooting the same sh*t as everyone else. Sorry, why should he have kept his job?

Smartphones are suitable for some serious photojournalism.

Operators without the skills or eye are not.

It has little to do with the equipment, and a lot to do with the experience of the person using it.
