ludwik123: Sounds like a fantastic new sensor.
Another nail in the coffin of the FF Canikon DSLR'S.
Mobile phone IQ is approaching FF very quickly.

LOL.
I can see the fumes from this distance.

Can't stress enough the clear advantage of RAW.
Sure, you can get some massive CA but the level of texture and detail available is in a completely different ballpark from JPEG.
(and coming from the Masters of JPEG called Olympus)

I say: "Burn the witch!"
If this gets into a chip inside the camera, how the hell am I supposed to recover those deleted pictures (that I shouldn't be taking in the first place) from the SD card???
Talk about a workflow knightmare...

tsk1979: Wrong pictures for this camera. I was expecting more deep-field. If nothing else, at-least the humble Horsehead!!

...or an infinite number of those!

On Nikon D810A: An astrophotographer's perspective article (113 comments in total)
In reply to:

jforkner: I think a few of the posters are missing the point of the criticism given. From the title & the intro, this article was supposed to extol the virtues of the D810A as they pertain to astrophotography. According to Nikon, “Based on the award-winning full-frame D810, the D810A records the brilliant red tones of H-alpha emission nebulae with a level of detail and sharpness, wide dynamic range and rich tonality almost unimaginable until now. Reveal the faintest celestial objects with exposures up to 15 minutes long; and noise-free performance at ISO levels as high as 12,800 (expandable to 51,000).”

While the included photographs are nice, they do nothing to demonstrate how this new camera is better at capturing the nebulae referenced in the intro or Nikon’s description of the camera. Nor do they reveal anything with a long exposure.

The criticism is of the the article’s purported intent, not the photographs themselves.

I was about to rant about the lack of a direct picture comparison to a "regular" 810, but you've put it all too well.
Given the title, this gallery is starting to look like an ad now.

In reply to:

Demon Cleaner: Page 4: "it would be really useful to be able to zoom in to the chosen focus point in playback mode, to check focus and shake, sadly this is something this is absent."

A double tap on the image enables selective zoom focus at up to 16x magnification.

Pretty much.
It was already like that 4 years ago on the GH2.

Johannes Zander: I'll chose this anytime over the dxo one because of flexibility and lens choice.
No matter how well DXO cooks their super RAW!

And look! It can swap lenses...

In reply to:

Mike FL: SONY likes users to "think" that new sensor is better in Noise/DR b/c larger photosite, but other than RX100-4 has 4K, there is really no meaningful difference in terns of Noise/DR from RX100-3.

Yes?

In fact it looks to me the other way around. I believe there is a small handicap in DR in favor of the RX-100 III.
I can't detect as many black patches in the RX-100 IV.

Make it over USB / Wifi.
Put on a filter thread.
Make it 300$.

Then you'll have a sale.

On Hands-on with the Panasonic Lumix DMC-G7 article (495 comments in total)
In reply to:

Hen3ry: The specifications look excellent, rather more than the doctor ordered! All I wanted was the new sensor in the G6. It almost looks like more camera than I can handle now! :)

I actually am not much taken with the squared off design. It actually looks a little like the old Topcon. The G6 might look a little shapeless but it has grown on me and except for a few touches, I would have been happy to see that shape continue. Great in the hand and rugged - my cameras lead a hard life.

Looking at the G7 capabilities, though, I am wondering how long I will stick with the GX7 I bought a month ago as a back-up for my G6. The GX7 might be a candidate for eBay so I can buy a G7 and use the G6 for back-up.

Pity they don't do n all-white version or even an all-silver one. I live and work in the tropics and a black camera absorbs heat more readily than I like.

No way, Hen3ry!
You should fess up right away that you wanted the IBIS too. ;)

Papi61: "The 1080p screen resolution looks a little dated next to the Quad-HD screens of many competitors in the high-end bracket"

Pretty hilarious how American tech media reviewers NEVER mention that about the iPhone 6...

So 1080p is not enough anymore just because there are QuadHD screens around?
I though we had learned something from the megapixel race, but humanity these days has a very short term memory... :(

4 pages of article could be summed up in 4 letters: ETTR.

duartix: By now I'm sure that Apple have a patent on copying ideas from other companies and patenting them. :)
That's why they can do it but when others try, they get sued. :P

I wasn't, I'm not very knowledgeable on patent trolls.

On Olympus OM-D E-M5 II Review preview (818 comments in total)

It's kind of an unforgiving let down when you get so much critics on the quality of the video you produce, and you improve what was already the best IBIS in the industry, support all the mandatory framerates on your container, increase the bitrate to stellar values and then...

... you keep that pre-historic sensor readout which line skips like there is no tomorrow, ending up with DR, low life sharpness and low light ability that doesn't even come close to the GH2 from 2010!!! :(

You really came so close Olympus. The camera is definitely amazing, but it's video output is still a big stain in the white sheet.

Nice but... will it zoom?

So, basically they changed an IF conditon on their old firmware and nnow are selling it as a new product?

In reply to:

duartix: Unless that black circle near the grip is another camera/sensor pair, I fail to even imagine how can they generate a focus overlap picture from a single combination of sensor/lens.

Even very advanced software solutions by Google (the google camera app on Android is such an example) need a minimum amount of parallax to reconstruct/generate a depth map and thus create a that focus overlap, but doing this temporally (à la Google) isn't practical on a rangefinder where you need immediate feedback.

Plus, if it is indeed a secondary camera/sensor pair, you will have to account for parallax errors on the focus overlap reconstruction. And what is much worse, you will have to be very careful on where you place your fingers when you shoot.

P.S. Before anyone else does it, I'm always ready to make a fool of myself. :)
http://konost.com/?page_id=7182
Yes there is. Now I'm just questioning the placement.

@Barry Pearson
I didn't understood your explanation to it's full extent, but I don't think that's how it works. This http://konost.com/?page_id=7182 shows a complete sub-area of the main sensor being superimposed. It's how they compute the offset that is the mistery. Maybe it's just a concept and they haven't worket it out yet.
But one thing seems sure: the two superimpositions look clearly parallaxed, thus probably beeing sourced from different points. Since the one on the display shows final DOF that can't be it. Probably one comes from the optical viewfinder and the other from the secondary sensor between the main lens and grip.
