PhotoKhan: I loved Erez's Kolmanskop series when they were posted and found this explanation extremely useful for the community.

I would just like to point out that, although the A7 (...and specially the A7II, it seems...) are a technology"tour-de-force", the mirrorless "to go to" at the moment, this is an instance where the praise to it's impressive DR capabilities is a displaced one, since the final photo was created through multiple exposures.

Notwithstanding resolution, I could as easily have created this with my EOSM2.

Errr...You DO know that, once we lift shadows, as Erez so aptly did ("I boosted the shadows to the limit") we ARE doing a kind of HDR, right?

Errr...of course.

...but, once you elect to use a multiple exposures technique for a specific shot, as it so aptly was in this case, the DR advantage becomes a moot point, since you might as well change the exposure solution as many times as you want.

That was my point.

Cane: That's a woman's purse.

@Marty4650

And, yet, it is simple to understand...

The reason some women buy "thousands dollars" purses is the very same reason why many of us buy "thousand dollars" lenses.

Edgar_in_Indy: Kinda sounds like a gimmick at first blush, but some home theater projectors have been using a similar method with their LCD panels in recent years to simulate 4K resolution, and apparently it actually works to some degree in producing a sharper projected image that approaches 4K. It'll be interesting to see how it works in a camera.

This technology may also be another nail in the coffin of the Canon/Nikon IBIS embargo.

IBIS has allowed such features as sensor cleaning, horizon correction, composition adjustment (in Pentax DSLR's), star/celestial tracking (again, Pentax), and now dual mode IBIS/optical stabilization in Sony A7 II. And Sony has shown that it can even be implemented in a FF sensor in a small body.

Now we just need Canon and Nikon customers to stop telling themselves that they don't need sensor stabilization.

Again, don't try to pick up a fight that is not there.
Just read and understand.
Happy Xmas!

You REALLY should ready what I actually wrote...You're trying to pick up a fight that is simply not there.

If IBIS closes the mind to such an extent, it might not be as beneficial as I thought it was.

I've got a concept for an entry.

It will be called "What The World's Best Spineless Rooms Are Made of".

It will feature a conference room full of Phase One's executives, all dully dressed in their Suit&Tie corporate fatigues, too afraid of losing their jobs as to call "What a douchbaggy, shitty-cretin, FU concept!" as the Marketing Director proposes this kamikaze contest.

It's in the bag...

I don't agree on 2 accounts.

Firstly, I don't know of many Canon user who are replacing IS lenses based on new IS interactions only.

What is happening is that the new lenses from Canon are significantly better in optical terms the the ones they replace (...and miles away from competition, in the case of long tele primes and zooms). That the IS on the new models is also better than previous generations that is is only a bonus, not a decisive "buy-factor".

Secondly, in-sensor stabilization is only a threat to IS lenses if it is offered as a substitute. If it is presented and implemented as a coordinated supplement to in-lens stabilization (...as Sony so cleverly is doing...) people will react accordingly.

Never underestimated the power of Canon... ;)

We, Canonites, don't say "we don't need sensor stabilization"

(...as for Nikonites, I don't know...they DID say they didn't need full format sensors, so...)

What we DO say is that current Canon lens stabilization technology is nothing short of amazing.

Given the pedigree, technical expertize and resources of Canon we might very well be surprised one of these days with in-sensor stabilization that can be combined with in-lens one, like Sony did with the A7II.

If it happens, one thing is for sure: It will rule.

(continued)

Revealing, because it denotes a tendency for a "political correctness" activism that, most surely, would have, at least, her face frowning if anyone attempted to start an intelligent talk about the actual physical and behavioral differences between men and woman, a frown that, from my experience, would quickly turn into "sexist" judgments, as quickly as one would say "PMS".

My ironic comment relates to how, when a commercial venture is at play (...ah, green, the pragmatic color...) all the "sexist" considerations are relegated to where they truly belong - actual instances of unacceptable discrimination based on sex differences - and, suddenly, the earth comes back to its immutable spin-axis from the "modernish-thinking" one and it is quickly and rationally admitted that men and women DO have impacting differences.

Of course.

You might have noticed, I was being ironic.

The designer and proposer of this bag is a woman. She seems to be a accomplished one and is a very interesting photographer (www.wrightfoto.com.au)

And yet, one of the first things she feels the need to say on her Kickstart video, at 00:20, is that "You don't want to be separated, just because you're a female. I don't want my work to be judged only because I am a female."

This is, at one time, both baffling and revealing.

Baffling, because why would she "don't want" something that, when it is done, only reveals the idiocy of those interacting with her or considering her work? Idiocy should be ignored not fueled by displaced militant assertions.

On Real-world test: Nikon D750 at the Museum of Flight article (281 comments in total)

Fantastic real-life test. I loved it (...in so many levels...)

Congratulations Nikon users.

You really DO have the best current DSLRs offers on the market.

As for DPR, I can only wish that it keeps evolving positively under this vector of Rishi Sanyal's of Barney Britton's video real-world tests and great interviews (...Barney is an aviation buff AND photography enthusiast...how "right" can a man be?... :) ) and less in the negative vector of the recent DSLRs recommendation list with side notes about not having tested them all.

Great job!

PhotoKhan: The (blatant lack of) quality of those images is extremely detrimental for the backing solicitation.

...and it just adds to the perplexity on why this would be needed in supplement to very fast shutter-speeds + standard flashes + advanced triggering.

Matt Kane should have stayed with Triggerrap.

As soon as my ADA triggers arrive I can show him, with glorious image quality, why this is a very probable "fail".

@EivindJohansen

Yes, you touched a sensitive nerve.

I've been very accommodating with the successive delays with Ada. I even told the guys down at Triggertrap, long ago on their KickStarter comments pages, that, contrary to many other backers voices there, I was OK with the delays as long as the product would come out as awesome as specified.

I am now confronted with the fact, unbeknown to us, that one of the initial developers has left the project long ago and is now asking for backing to yet another project, leaving us to wonder how his departure has affected the schedule of Ada's development.

...a bit murky, if you ask me...

There's nothing wrong with riding the current popular-back-financing wave, even if only to see coming to fruition "this-little-engineering-idea-that-I-had".

But, please, for the sake of your backers, DO face the applications and operational limitations your project may have.

(Please thank you daughter for the cool, cool name for such an radically-innovative product. If she's still in an age as to reply "goo-goo-da-da", it's OK. I know what she means :) )

Regarding the first paragraph in your comment-reply...

The fact that the photographs are of poor quality has much more to do with the inadequate light output than with your putative existing or non-existing photographic abilities, as the declared GN demonstrates. (You could have hired Annie Leibovitz. They would probably have looked just about the same, bar the inordinate amounts of Photoshop her crew would have certainly used). The problem is low light level. It is very impressive to claim for a 1/2,000,000 seconds light pulse...but it has to be "operationally illuminating effective", which it was not in the included image samples.

...If the intent is to capture BB pellets and bullets (...I can't see any other applications...) you should warn users that the close-in distances at which the light source has to be set-up may, in fact, be detrimental for the LEDs...err..."health"...for those with poor aim :)

@TTMatt,

I understand why it is "needed", that is why I wrote "in supplement".

My point is: How often do you, myself or anyone else, apart from, I don't know, forensics experts, need a dedicated light accessory to absolute-freeze BB pellets or riffle bullets in flight?

Once one has access to a 1/8000 shutter camera (...I know this is done with long exposure times to "kill ambient", I know...I mention the high shutter speed limit camera as an asset for "high-speed" photography, in general...), a series of speedilites and an appropriate trigger, most "flash-event" high-speed photography is catered for.

Selecting low-power output can take speedlites up to 1/25000th of a second and make them do things like this: http://strobist.blogspot.pt/2009/02/winter-treat-frozen-hummingbirds.html
