On article UPDATED: Sony a7R III is still a star eater (341 comments in total)
In reply to:

Life recorder: Of course the Sony's still have this problem. Most still overheat on warm days while shooting video too.
This is the problem with Sony. When there is an issue like Star eating, overheating, lack of weather resistance, etc., Rather than speak up and get Sony to resolve the problem, the majority of the faithful either say the problem is "overblown" or deny it even exists. Worse, a few will get upset and attack the messenger. Instead...

Let's thank DPR for taking the time to report this so those interested can take it into consideration.

The problem is overblown.
It is, really.

WHAAAAAAAAAAAAT THE!!!!???

1/3 the price but still WHAAAAAAAAAAAT THE!!!????!!??

That is insanity, especially for such low specs and NO LENS!!

Another Kickstarter scam for ignorant people...!

Father Bouvier: I suspect those Ukrainian guys bought a wheelbarrow of Kiev 19 (http://www.collection-appareils.fr/kiev/images/Kiev_19M.jpg) cameras for $10 a bucket, which were forgotten in some warehouse some 30 years ago, and now they want to monetize on that find.

Nice find... it's exactly the same model.

Reading the reports from the company, it looks to me like Nikon is in trouble, no matter how many times you write FACT.

ilza: Warning: FAKE DATA! Well, at least fake to SOME extent!

DISCLAIMER: I did not try to read the paper, but I did read through docs in the source distribution. FACT: this software is trained on COMPUTATIONALLY DOWNSAMPLED images to make it perform best on such images. CONCLUSION: the presented images in no way reflect the behavior of the algorithm on “real” images.

Having said this, “real” images are “optically downsampled” from the subject, and noise+demosaicing artefacts are added. It MAY actually happen that the “actual” behavior happens to be close to the presented one.

Anyway: in applications where “what actually was in the subject” does not matter (comparing to “what is an educated guess about what could have been in the subject”), this is very impressive! AFAICU, the main achievement is the tiny size of data they need about the universe (3 megabytes!), and a lightning speed.

HOWEVER: I cannot stop thinking about what a great de-Bayering algorithm one can make out of this!

The fact that they use downsampled images to feed the neural network is ok, but to present upsampled images that have been downsampled before is misleading and doesn't represent real use. A downsampled image simply holds a lot more information than an original low-resolution image that hasn't been downsampled before - which would be the real-world case.

Dante Birchen: Much joy among Sony fan people, the vast majority of whom will never be able to afford this $15000+ lens.

@T3 - Have you checked some reviews of both the Canon 400 f4 DO II (second generation) and the Nikon 300 f4 PF? They are both optically outstanding lenses, with hardly any real disadvantages, except maybe loss of contrast when shooting directly into oposite light. Both of these lenses are very sharp and are not much more expensive than if they were a more standard design. The Canon 400 DO II looks like a bargain at 6'450 CHF (Switzerland) against the Canon 200-400mm, which costs 9'899 CHF... so I guess cost is all relative. Sony has not much to lose in this category of lenses anyway, so they could easily price it below the competition. After all they want market share and prestige, and won't make the big profit with these lenses, no matter where they set the price point.

@T3 - You are probably right with some of these thoughts, BUT: If Sony wants to really attract pros (and wealthy enthusiasts) that are now shooting Nikon or Canon, they need to create advantages not only with the cameras, but also with the whole system, which includes the lenses.
Don't forget that Canikon lenses can be adapted to Sony e-mount, so the Sony lenses have to really give the user an advantage. I think the latest offerings such as the 24-105mm or the 100-400mm GM lenses, being both of exceptional optical quality, are a step in the right direction - but for a 400/2.8 a size/weight reduction with Frensnel technology would make sense, IMO.

Sure, that's true Dante Birchen... but e-mount only exists for a few years, so it could hardly be otherwise. And since Sony is only now developping longer fast lenses for E-mount, it will take some years until any of those will be on the second-hand market.
The good thing is, they ARE trying to challenge Nikon and Canon in this field, which will animate this segment somewhat. For me, the big question is: Will Sony find a way to create a real advantage for the user (price, lens-design, weight, size, image quality, features), or will it just be a "we have big lenses, too" thing, with more the brand image and marketing in mind than the user. Unless they really make a better (or cheaper) lens than the the competition, they will have a hard time competing.

Richard Kwon: I returned my new D850 this morning. I am going to convert completely over to Sony with the a7riii. I was very worried with the D850 lack of IBIS. I had an a7r and lots of my photos were blurred. The a7rii's IBIS took cared of that problem. That is why I did not open my D850 box, because I was worried it will do the same with no IBIS.

I tried it out last night with my Sony A77 and Sigma 17-70mm... with that combo I can basically get sharp photos at 17mm wide-angle up to about 1s exposure, hand-held. As soon as I zoom in to 70mm this is reduced to around 1/10s, (if I lean my back against a support). Now it is well possible that the Olys have a better stabilization (and maybe newer Sonys, too), but of course, the well-known quintessence is, the shorter the focal length, the less shake affects the image.

Oh no, is it too sharp for you? :-) It's quite impressive actually, right down to the corners... that should be forbidden for a zoom, because it makes some of my primes look ridiculous!

Dante Birchen, if we are not talking latest versions, there is not much point in this discussion.
I use a Minolta 400mm f4.5 btw, which is excellent - hand-holdable, and very sharp even with 1.4tc. Cost me around 2000 bucks some years ago.

Ok TN Args, I must have missed that then. True, no Sonikanon would do such a thing easily. As for leaning against a support reduces the glory a bit, but it is hand-held nevertheless.

To Impulses:
I must be living on another planet then, with time going by more slowly. 5 seconds hand-held without motion blur, really? Can you point me to some samples of 5s exposures where the author explicitly says that they were taken hand-held? (I don't care if they were taken with an Oly, Pany, Sony, or a card board box.)

In reply to:

ProfHankD: 400mm f/2.8 lenses are never cheap. Canon's is $10K, Nikon's is $11K... although Canon's f/4 version is just $7K. Given such a small price difference, I think Sony going with f/2.8 instead of f/4 makes a lot of sense, and as long as they're under about $15K, they'll sell plenty of them. (No, I don't plan on buying one.)

I think the DO/Fresnel/PF lenses have evolved quite a bit since the first DO designs from Canon. The 400 f4 DO II is markedly better than the first one, and the Nikon 300 f4 PF seems to be very popular because optically it is hard to distinguish from the classic 300 f4 version while being almost half the weight. So I really think that the technology and optical quality of this design type have evolved quite a bit, with maybe the only shortcoming being a reduced contrast in direct opposite light.

IMO it would definitely make sense for Sony to go in this same direction as well.

I'd like to see those 3 seconds hand-held exposures... it would not only be a different world, but close to a miracle if any IS system was capable of that on a dslr.
Oh, and I'm a pixel-peeper, I examine the photos from very close, and with the slightest hint of motion blur they go into the garbage bin... ;-)

OhWeh: Another, and a huge, nail in the coffin of non innovative DSLR-companies.

I fully agree with Osu. Not to forget, Canon and Nikon will also face the same size dilemma in terms of ergonomics: Make it large, there will be no size/weight advantage, make it small, it will look off-balanced with larger standard mount full-frame lenses + adapter. Make it small, Sports/Wildlife photographers might not buy it (also because of the EVF), make it large, everybody else might not buy it. Dilemma over dilemma... :-)
I am very much waiting to see their offerings though... Sony's latest models might be hard to beat in terms of what they offer.

Paul B Jones, thanks for the info, but Dante Birchen was talking about $5000... so that was maybe somewhat illusionary.
In any case, it is true that for long Canikon lenses there is a substantial second-hand market, but thinking that these lenses sell for cheap is an illusion.
Sony is an entirely different story, of course, because the long fast lenses are hardly existing yet - but that's why they have started developing them.

Jay557799: The 500 f4 is $13K. 400 f/2.8 is "more lens" so $15K sounds reasonable. The used market of the 500 is practically non-existing. Took me 18 months to find one ... in Austria.

The 500 f4 is for A-mount. If they are smart they will price the 400 f2.8 more in line or even slightly below the competition, because they will win a lot more prestige (and $) if pro photographers actually use it. It is the E-mount they really want to push.

11-12K seems reasonable, that's about the price of the latest Canikon versions when they were announced.
As for the energy consumption, it will certainly consume less if it doesn't have lens-based stabilization and relies on the camera IBIS, like is the case with the Sony 500/4 for A-mount.
