Pritzl: I'm still looking for the catch. Otherwise, this could be quite the game-changer.

The catch is pretty obvious - it will be expensive.

Even if it weren't significantly more expensive to manufacture (which, given the nature of its construction it undoubtedly will be) it will be in high demand - that means the products will be able to command a hefty price premium.

vbuhay: This will be the death of Hard Disk tech....SSDs will be the standard of bulk and cache storage and maybe DRAM. This technology might also be applicable to Micro Processors, DSPs and who knows - sensors?....Flash is on its way out as well. The largest Flash memory manufacturer Samsung must be shaking in its boots. Watch how the price of Flash NAND devices go down. 25Cents/ Giga Byte flash and lower.... XQD, CF are both dead... SD or Micro SD from here on!!!! It will be interesting the next 10-20 months and I mean months not years.

That depends an awful lot on its cost, which isn't mentioned in the article. Given the extra fabrication steps that seem likely to be required for a chip like this, I suspect that this kind of memory is not going to be cheap. I have a feeling that hard drives are still going to be around for a fair while yet because they balance low cost with tremendous capacity. There's still a huge need for bulk storage that doesn't have to be super-fast.

Lab D: Just read nerd2's classic comment abour how since f2.8 on m43 is really f5.6, and so apsc with an f5.6 lens is better. I bet he still doesn't get why that is so funny.

All this equivalence talk is IRRELEVANT if the shots you're taking aren't limited by noise and you don't need shallower depth of field. I come from film days, and IMHO today's sensors are so capable that I simply don't require any better noise performance that what my M43 camera provides. And if I think I'm going to need shallow DOF I can bring along my f/0.95 Voightlander. So why on earth would I want to lug around a larger camera and a collection of larger lenses for it?

photoshack: Hilarious! And those who don't actually understand why you would use a selfie stick...well I guess you have been lucky to have decent photos from well meaning nearby travelers. I have not seen one yet that was as good as a selfie stick version.

It's called a "self timer". And it lets you get pictures where you're not always at "arms length".

On Sony Cyber-shot DSC-RX100 III First Impressions Review preview (2962 comments in total)
In reply to:

Marvol: I've got some olde manual lenses for my NEX-6, one with a clicky aperture ring and one smooth. I prefer the smooth, although that has also to do with the fact that it gives fully "analogue" aperture setting.

Which leads me to the question, does the clickless ring in the RX100 also translate in to stepless aperture setting or does the aperture change in 1/3 intervals, just without the tactile feedback?

And worse, if it's like the Mk.2 ring it's very inconsistent in its operation. You have to turn it a fair distance at a certain speed to get it to do anything, then subsequent changes come with less rotation. It's pretty much impossible to use intuitively, you have to pay close attention to what you're changing (I have mine set to EC compensation) to make sure you've reached the desired setting and haven't overshot it. And if you do overshoot then it's back to square one to correct.

It's not a show-stopper for me, and it's better than having to push the buttons to make the same change. But it annoys me every time I use it. Fortunately the rest of the camera is so good that it more than makes up for this deficiency.

Based on Microsoft's track record in this area, this sounds like the kiss of death. Zune, anyone?

In reply to:

tecnoworld: It would be nice to control the Axis360 with an android device, instead of the 250$ controller...

The controller is going to be required because it's what sends the control pulses to the stepper motor. By the ability to PROGRAM the controller from a USB-connected phone or tablet would be a hige plus, IMHO.

Scrubby zoom and temporary tools are terrific tips. Scrubby hand is too, but I already knew about that one. BTW scrubby hand works in a lot of other Adobe products too, such as Acrobat Reader.

nickthetasmaniac: the most boring release in the last 12 months has 402 comments.


It's because a lot of people have really, really been hoping that Canon would get serious about mirrorless cameras. After being disappointed by their first model, this is even more of a let-down - especially since it seems to suggest that there's little or no future for the line outside of Asia.

On Enthusiast compact camera 2013 roundup article (236 comments in total)

I don't have any experience with the other cameras, but AFAIK the RX100M2 is plenty enjoyable to shoot with. I've customized the dials on mine to the functions I use most often and find it easy and pleasant to use. But I will admit that it takes the optional (and inexpensive) Sony grip to really bring it to life.

On Panasonic DMC-GM1 preview (631 comments in total)

Yup, Panasonic again makes the mistake of thinking that a small camera has to be a dumb camera. I see a dearth of controls and crippled video. The Sony RX100 and RX100M2 showed that people are willing to pay good money for a compact camera that's designed for enthusiasts, not point-and-shooters. When will Panasonic get the message?

On Sony DSC-RX10 preview (722 comments in total)

The price is in line with what this camera offers over and above an RX100M2 - namely a built-in EVF, top LCD display panel, and a very long range, constant-aperture f/2.8 zoom. Trying to get that combination in any other camera with a sensor at least this large would be a lot more expensive.

On Can computer corrections make simple lenses look good? article (163 comments in total)
In reply to:

Roland Karlsson: Interesting.

I wonder how it performs if it is applied to a rather good lens, like an average zoom kit lens?

I know nothing about how this works, but I suspect that a more complex lens would have a more complex point spread function and that might make reconstructing the image significantly more difficult.

On Sony Cyber-shot DSC-RX100 II Review preview (516 comments in total)

I recently purchased an RX100M2 and am very pleased with it. It delivers still and video results that surpassed my expectations, and has a quick menu and enough assignable function buttons and dials to provide a very capable shooting experience even for those who never go near the "Automatic" modes.

I agree with the criticisms of the front control ring - it is frustrating to use because of the lack of feedback and rather erratic response to movement. And the camera really needs to have the optional Sony grip affixed to be decently "ergonomic". But those are really the only two negatives on an otherwise very impressive product.

It's an expensive product, but it's really in a class of its own.

Yet another promising Nikon camera that I have to exclude from consideration because they didn't bother implementing 1080p60 video. Only Sony and Panasonic seem to be getting this right...

Direct link | Posted on Sep 9, 2013 at 16:58 UTC as 9th comment

Too little, too late. I've been waiting for what seems like forever for Canon to get with the 1080p60 video programme, but I just bought a Sony RX100M2 because it's the first compact to have both that and a flip LCD.

Sorry, Canon - you snooze, you lose!

CameraLabTester: Try dropping one magnetic tripod on the soil during a hike and see all the gold nuggets attached to it when you pick it up.

Great for prospecting.


Gold is not a ferrous material so magnets won't attract it. If gold were magnetic then prospectors wouldn't need to spend all that time swishing water and streambed gravel around in pans.

Heck, not even US coins will stick to a magnet. Might find some nails, though!

In reply to:

Tim Ashton: nice strong magnets wont corrupt cards???

I suppose if you used something like an MRI machine it might induce enough current in a flash memory card to damage it, but normal magnets like the kind found in these tripods won't affect it because the data is not stored magnetically. Heck, normal magnets won't even affect hard drives, which DO store data magnetically.

In reply to:

Juck: Make the bloody ink affordable and non of this would be necessary.

Absolutely. A good deal of the recycling problems we have are due to planned obsolescence, including unavailability of ink / toner supplies, proprietary batteries, etc.

Many of our environmental issues aren't just the recycling of this stuff, they're caused by the big environmental cost of having to manufacture the new stuff that takes its place.

The real solution to our problems is to lessen our dependence on being a consumer economy.
