WHAT THE...!?!?...oh...wait...it's not my $6.5 million...That's OK.

On Lytro software update introduces Focus Spread feature article (104 comments in total)

This is very impressive, especially when we consider that we are still in the early interactions of the technology.
Myself, I WILL stay tuned...

Roland Karlsson: Hmmmm .... whatever it can do - it sure is ugly.

Well, at least and unlike Foveon cameras, even if not that vibrant the colors make sense for those of us not afflicted by deuteranopia.

On Leica M9 users report sensor corrosion issue article (379 comments in total)

Leica is about to find out how one of the types of users they so adamantly and constantly target should actually be avoided.

They might not have a clue what that rangefinder locked in the display serves for but they sure can smell a drop of blood in the sea of litigation from miles away.

Cooleator: I can see the logical differences compared to lower mp FF, however I'm pretty sure a 30mp+ FF Foveon sensor would trounce this 50mp MF sensor at low ISO...

...sure...as long as you don't mind having whatever colors it decides to reproduce instead of the actual scene ones.

Mal69: I miss the days when people just took photographs, now its all about who can do the best job using Photoshop applications, it feels a little like cheating to me as i never know if the photograph is natural or heavily changed using the computer.

I have news for you.

Remember all those gorgeous coffee-table book photos from film days?

They were all manipulated to some extent after been registered.

If you never saw the dodging-spill around the brims of Georgia O'Keeffe's and Orville Cox's hats from pushing the shadows under the hats in that famous photo, you must have been severely distracted.

Every time someone makes the statement you made about the use of Photoshop in the same scope of when previous lab-only techniques were used, I only consider 2 possible explanations:

1. The statement is a snob one.

or,

2. The person making the statement does not know how to aptly use Photoshop and resents it.

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.

My point, again...

Once you use a shooting solution based on multiple exposures (as was elected here, for a diferent purpose) all considerations about sensor DR become a moot point.

For all practice purposes, at 100ISO (as used in this photo) AND multiple shutter time exposures to cater for highlights and shadows, there would be no discernible difference (except for resolution) between an image made with the A7 and one taken with many other mirrorless cameras, EOSM2 included.

Superior DR helps in a multiple exposure composed photo as much has 12FPS helps in a posed photo.

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.

@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.
