In reply to:

Jonathan F/2: I thought it was a wearable belt as well? I'd prefer to use it to hold up my pants and camera!

Me too, would love to be able to sport this around my waist. That way I'd have use for it the 99.99% of time were I would otherwise have no use for it.

maxnimo: So what's the actual, real resolution of this camera in real, actual pixels??????

Bottom line is that it's not fair or accurate to compare the sensors directly in either way. You could argue Sigma should state the actual pixels, but until the Foveon technology is as common as CCD or CMOS that information will be misleading to the reader, effectively making the specs worse than they are. It's easy to understand, and accept, that Sigma needs to rectify this in their marketing.

And as you said, the resulting image quality can be compared to a conventional sensor with much higher actual number of pixels.

"The claim of 39mp comes from the notion that you could enlarge the image up to 39mp and it will still look as good as a 39mp image from a normal (Bayer CFA) camera."

Although that can certainly be the case, this is not quite accurate. The claim of higher amount of pixels is the fact that the image is read through three layers of pixels - red, green, or blue .

In a conventional one layer sensor each pixel records just one color. Regardless of how many pixels a CMOS or CCD sensor has, it captures only one-third of the color information. Then the image processor must interpolate the color they miss. Interpolation will always have a detrimental effect on the picture. So the term resolution does not directly translate to number of pixels (as has been the convention since the birth of digital sensors).

Stephen787: may i know why they do not enter the market to compete with metabones mk4, but go to tiny little market for SL.

how many people have a SL.

As far as build-quality goes Novoflex is two divisions above Metabones. I know because I have numerous adapters from both (and other) brands.

StephaneB: Today is sad day.

This is the confirmation there is not any development planned for that outstanding software. Either the developers left or they've been fired already.

This thing is dead now. Expect it to follow Picasa.

Google is turning into a graveyard.

Where have you been for the last 3 years? There is no development to halt. Just money to be saved for new users.

El Chubasco: What's the strategy here? Can someone explain?

I don't think it's a strategy as much as it's a sign that few people chose to pay for this suite in 2016.

This is a way to keep it alive for a way longer. And with everything Google the more you use their products the more they tie you into their universe. That's not necessarily a bad thing.Getting great software for free is a good thing in my book. Then again I'm not a paranoid conspirator.

Keith Cooper: With a lot of people new to the software I hope this info is of help. I still use them regularly, with Sharpener Pro being a frequent part of my print workflow from small snaps to 3 metre prints. I've written up details of how I use many of the plugins.

Hope it helps?

misolo: Does anyone know whether this is in preparation to discontinuing development and support? They're still great tools.

Everything points to that unfortunately. Google bought Nik to get Snapseed.

photophile: in my 11 years in Dpreview - I have never read a thread/discussion where all the posters agree unanimously on their opinion of a product - until this announcement. Never has a forum populace been more in harmony.

I therefore nominate this "invention" for the Nobel Peace Prize.

But of course, it won't be possible to record the auspicious moment in Stockholm as far too many people have already done that over the years.

We finally did it! I call for a GROUP HUG!

GaryJP: They might be assuring us they are going to keep Lightroom as a standalone product, but it is a nightmare to get through their site without being signed up to a Creative Cloud you don't want. They are just pushing the standalone right to the periphery.

Liars. As we always knew.

You can call me a troll if it makes you feel better, but at least know I am a troll with a stand alone version of Lightroom.

In reply to:

Top Dog Imaging: Who currently owns this camera? It should reside in the Smithsonian or at least the Kennedy Space Center. Taxpayers footed the bill.

Seeing as you present it as such, do you know this for a fact? Or did you just assume?
