LegacyGT: For anyone else confused by how a single lens camera can capture a 360 view.
I did the extra investigation and discover this camera has a 220 degree FOV wide angle lens that is designed to be pointed straight up... so it has a 360 degree in 2D.

Most other "360" cameras (Ricoh Theta, Nikon KeyMission, Insta360 Nano, Samsung Gear360,etc) offer a 360* in 3D (i.e. spherical view) via two ~180 FOV lenses stitched together.

If you thought "well obviously," sorry I wasn't so quick on the uptake as you.

...the power of marketing! :)

On article Lensrentals tears down the Nikon 105mm F1.4 (156 comments in total)

A very interesting and well-done blog post.

I like better and old but practical design, than a newer, less repairable one.

My bet is on the marketing department knowing next to anything and just blowing his own trumpet.

WillWeaverRVA: "The 64GB version will set you back approximately $435 while the 128GB requires an investment of $480."

I'm not sure why anyone would want to buy the 64GB version...

There it is: iphone 7 32GB was slower than the 64 and 128GB versions (39.6, 200.6 and 308MB/s respectively).

A real-life test however showed that a copy of a 5' 4K video took about a minute on both 32GB and 64GB variants (52" and 1' respectively), and just 17" on the 128GB model.

Melchiorum: It seems like the smartphone market has hit a wall and has not been going anywhere for past couple of years. Everyone keeps releasing the same product with the same faceless design and pretty much the same specs. A bit thinner, a bit faster processor, a bit better camera, a bit brighter screen... A bit, a bit, a bit. Well, some have added a second camera gimmick which no one really needs that much. Even the new iPhone was pretty much the same as previous one.

The only somewhat interesting phone was Mi Mix by Xiaomi of all companies, but it's only available in China.

Yup, it has reached a plateau since some time... moreover there is no obvious benefit in choosing a "better" model anymore, as it was the case just some years ago... mid-range is more than sufficient for almost everyone, including geeks.

Well, if the only difference is storage, then 32GB could be enough...

In general a version with more storage is made with a little more RAM, or even a non-declared difference in trasnfer speed (it happened recently with iphones, IIRC), in order to give the buyer an incentive to choose the better model.

On article Shaking up the market: Pentax K-70 Review (333 comments in total)
In reply to:

Adam Sharp: Pentax great value for money

@rrccad it could be only 50g... the global weight difference also could come from the fact that Pentax cameras are usually built like tanks, even entry-level ones.

I held a Canon once and it was very toy-like, with plasticky look & feel, wobbling controls etc.
The simplest ones from Pentax (I own a K100Ds and a K-01) are sturdy and have a strong metal frame.

Biowizard: PS: That thing is going to get HOT without adequate heat-sinking.

Brian

[edit] - and for me, a surfboard and the ocean does not qualify as heat sinking ...

...it depends how much weight you put on said surfboard (otherwise it's heat floating)

Tommi K1: Isn't it meant to be written as 21'650 frames per second?
As 21,650 frames per second reads like 21 and 650 fractions of frames per second...

In Italy we use the single quotation mark (') to separate thousands - it's actually written as a dot at school -, and the comma (,) is used for decimals.

In order to avoid confusion and issues with badly-coded software, I always change the settings of every PC I configure to use the dot (.) instead of the comma.

Much more interesting than the fluid base I own, I'm afraid...

While panning is indeed fluid, one always has to interpolate panning with other motions when moving at an upward or downward angle, in order to keep the panning plane leveled (easier to demonstrate than to explain).
That way, the ball joint is always used in conjunction with the fluid one, potentially leading to potential jagginess in the motion.

OTOH I mainly use my monopod for stills, I had the occasion to film more before buying it than after (but I didn't know it would have been that way). All in all I'm happy I have a versatile piece of equipment, sadly the fluid foot is not replaceable.

John Koch: Is Galileo an honorary member of the PrimaLuceLab board of directors? He needed pen and paper to transcribe celestial observations. On the other hand, he could find star-filled skies virtually anywhere. His telescope would have captured nothing in today's urban skies.

What is the cheapest effective device to offset earth rotation? I suspect that trailing caused by earth rotation is a serious obstacle to time exposures over 30 seconds. I also surmise that light pollution precludes time exposures above 10 seconds where most people live. Those "dark sky" sites tend to be rather remote, difficult, or spooky. Oh, and clouds.

Cheapest, a "barn door".
Otherwise yeah motorized devices.

Debankur Mukherjee: Lets get ISO 100 image quality at ISO 3276800..............is it possible............

ISO noise and long exposure noise are two completely different things.
One is due to amplification a signal and its underlying noise, the other to the sensor itself, when it heats up.

Najinsky: It's the airline aspect that will likely affect me most.

I'm a near permanent traveler which goes hand in hand with my photography.

I can see this driving new types of ban on various portable electronic devices. There are already limits on lithium camera batteries for some airlines.

We might be heading for a whole new chapter in air travel inconvenience again. And while it's easy to criticize the lazy generic nature of some bans, I have to confess the idea of being stranded at 32,000 feet on a blazing airliner, really doesn't hold any appeal for me at all.

...or simply that existing restrictions could be enforced more strictly. I agree.

I took quite some planes in the last few months, with different airlines, and aboard all flights there was an announcement regarding the Note 7... sign of the times I guess...

Limits on Lithium batteries were operationals years before the Note 7 case... they were never a hindrance even for power-users equipped with power banks, something around 30-32 Ah IIRC, while my powerbank and my phone combined only reach about 20, and it's all "new" stuff that wasn't so commonplace just a couple of years ago (phones were 1.5-2 Ah instead of 3-4, powerbanks, lipstick-style, 3-5).

sh10453: I already made the replacement.
I got the Huawie Honor 8 (now on sale for $350 at B&H, with quite some nice goodies as a bonus for a limited time).
I got the 32GB version.
4GB RAM is great! Octa-core processor is awesome (2 quad-core processors).
It takes up to 128GB micro SD card.
Feedback from friends and family regarding sound quality (voice from my end) has been rated excellent.
I like the image quality of the dual lens camera, and the available options in Pro Mode photography.
This is my first time to use a Huawie product, but I'm very pleased with the phone.
In fact two of my friends are dumping their iPhone 6S/Plus and getting the Honor 8 due to poor sound (voice) quality.
Highly recommended.

I have a 40" 1080p tv and a 5.5" 1080p smartphone... I guess 1080p on the smartphone are enough...

In reply to:

coody: Because Sony RX100 V limits 4k for 5 minutes, user should prefer Panasonic LX 10.

Yeah, I will definitely buy more as budget permits and tech advances... next one I'd like to be at least 4k (for cropping purposes), now that prices are manageable.

Audio is my No. 1 priority though, so other mics come first :)

Quality from the action cam and the camcorder is about equal... they are both lousy! :P

I don't... since my still cameras can't cope with continuous recording, I was forced by budget constraints to buy a consumer-grade camcorder and a Chinese-quality action cam (camera 1 and camera 2 in my setup)...

...but I do have a proper external recorder (XY integrated stereo), and a nice large diaphragm condenser mic for accents ;-)

But boy, would have I liked an interchangeable lens camera that allowed continuous recording for as long as a couple of hours... I could have put my nice lenses to good use, instead of relying on that purple-fringe-producing plastic pile of excrement that is my camcorder... :-/

Who said it would have been the only camera?
Who said audio was to be from the in-camera mic?

I personally place different cameras around, but the point of having cameras that record continuously is precisely to free your hands (and be able to do other stuff, be it performing or recording with other devices)

@DaGuardian Well, sometimes it is necessary to do so...
To me as well limitations on continuous video recording are quite important.

zakaria: Shooting at 1:1 crop mode is a great addition.
Thanks Ricoh.I use pentax dslr since 2008 I never got an update from Pentax that add some features except this new firmware.
All pentax firmware updates were to enhance general stability.

...something like a multi-aspect APS-C sensor in addition to the FF one, I like it!

Yep, my opinion as well.
