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...

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.

On Going solo: DxO introduces 20MP 'ONE' connected camera article (124 comments in total)

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 (493 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 (811 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. :)

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.

In your dreams perhaps. I suggest you check with reality here:

On a blind test you will never tell the difference.

Perhaps you should upgrade your studio poster to include a waterfall. ;)

In reply to:

tkbslc: Seems like a waste to put effort into making the video mode nicer and then leaving off the headline 2015 video spec - 4K.

It's biggest problem with video is not about not featuring 4K.
It's because it is still heavily line skipping on the FullHD readout. Yet, 2/3 (bitrates/frame rates/readout) is not completely bad at all.

In reply to:

UnderDriven: Olympus may want to consider implementing a 4-image mode which does not increase resolution, but does provide full color sampling at every pixel...

It's there already @UnderDriven.

It's called the 40 MP multi-exposure mode. It just needs you to dowscale the result in the end and it takes a little longer than what you wanted. ;)

You are welcome.

Not for an instant. But perhaps we should. Sellers gotta sell.
