On Aloha! We go shooting with Samsung's new NX500 article (184 comments in total)
In reply to:

mugupo: Wait till Sony A7000 which just around the corner, it will likely put this camera to shame. with EVF and better video function.

"Just around the corner"? Sez hoo?
The November rumors alleged an unveiling at CES in January. Sony evidently took fright at the NX1 and needs to convalesce a year or so to think up what to do.

No auroras or glaciers visible where I live, just light pollution and slush. A macro shot of a dirty snowball with a glow-stick, maybe? Or "March Thaw: Diner Parking Lot with Neon Signs."

The next time it rains cats and dogs, I'll try taking a picture.

#1 worry: motion blur might make animal lovers complain they can't tell the canines from the felines: "Bunch of fur balls. Looks Photo-shopped."

#2 worry: the photogs will sneer and say that I used the wrong camera, failed to control sky back-lighting, or that their blurred waterfall pictures look better.

Lauterbrunnen farmers complained when BASE, wing suit, paraglider, and other aerial dare-devils began leaving corpses on their properties, scaring the cows. A disproportionate share of Alpine cows die in falls, so maybe their is an in-bred anxiety. There must also be a bovine wisdom or resignation that one cannot cheat death for long: today clover, tomorrow chopped sirloin.

On Sony Alpha 7S Review preview (467 comments in total)
In reply to:

Hubertus Bigend: If dpreview wants to start basing results of camera reviews on cameras' video capabilities, they ought to open a new 'dvreview' site and do it there. For people interested in 'digital photography', not videography, results significantly influenced by video capabilities destroy all comparability.

Then again, 'overall scores' have never been too meaningful, anyway...

DPR is very explicit that the A7S is video-centric. The review and scores don't mislead anyone. However, by any standard, the low noise high ISO sensor is an outstanding distinction that merits a high score. People have to stop looking at a high score as a threat against some (probably dated) camera they bought. To say that video adds nothing to a camera is like saying that a camera or toch screen add nothing to a phone or that a "flying machine" adds nothing to a navy, or that drones degrade the soul of an air force. Yes, video is more challenging than still photography, but not a detraction.

In reply to:

zodiacfml: Awesome review. I thought the review is too late but the technical information provided are plenty and high quality. Good thing you gave this much effort for the very intriguing 12MP FF Sony sensor.

Regarding DR, I believe it has something to do with the noise in the electronics or lossy RAW compression of Sony limiting the DR of the A7s similar to its brothers. A7r had it better because of the image size reduced to 12MP which increases SNR.

Sony, put this sensor in a $1,000 body then we have a new "Rebel".

If penny-wise Canon projected no profits in a <$1k FF camera, it would probably not serve Sony either. Will Canon (or anyone else) emulate Sony's A7s in a $3k body? No signs of that either, yet.

jkoch2: An excellent camera for limited motion video, especially in low light, or if one cares to use an external recorder and focus manually. Not so great for fast action, whether for video or still shots, due to sluggish AF. If shooting sports, the limit to 12 megapixels, per se, is less of a drawback than the AF factor. Internal 4k will remain difficult to implement on a FF, absent either a big heat sink or forfeiting the internal IBIS of the a7ii.

Might the a7000 offer, in an APS-c system, what the A7s does not? Sony may not be thinking in those terms, but the battle imperative to beat the NX1 may compell Sony to make it do just that.

Doesn't the <$100 EVF10 hot shoe accessory answer that? Except under bright sun, one can live without an EVF and save space. It may be preferable to keep the touch screen LED illuminated anyway.

In reply to:

munro harrap: Obviously the costs of sensors is tiny these days. Everybody constantly redesigns their sensors and then gives them more or less abilities but nobody produces an affordable machine that does 4K in-camera with a 36MP full-frame sensor, or a 24MP APS-C sensor if you really must.

So go down the lists and look and feel you are being robbed spending now, because you are.

I expect either of the above with a 5 year warranty NOW.

Panasonic are offering free 5 year warranties with some of their 1" machines, and these are delicate plastic affairs with built-in lenses (much more to go wrong!)

And these are capable of reasonably excellent in-camera 4K at a third of the cost of the Sony A7S all by its ickle self.

N.B. the new D7200 STILL has no 4K recording, nor the D750, nor the new Canon 50MP machines, its like having a computer running windows 98 on 2Gb Dram, they are refusing to equip hi-res still machines for hi-res video, it's a plot!!

The Samsung NX1 and NX500 have a 28mp BSI APS-c sensor and shoots 4k video internally. The NX1 body costs about $1,600. The NX500 is slated to sell for $900 with kit lens included.
I'm not expert on warranties, but would guess that the 5-YR terms apply only to expensive or pro-grade models, or else have all kinds of limitations or exclusions (fire, drowning, condensation, crash, etc).

In reply to:

AbrasiveReducer: Are there any stats on how many people routinely shoot video but don't own a video camera?

Like sailors who don't use boats?

Millions, perhaps billions, of people with smart phones shoot video and have neither a camcorder, a DSLR, or a P&S. Camcorders have been displaced by both phones and by the increased video quality of hybrids or other cameras. The smallish crowd that wants cinema-like look, but lacks budget for Hollywood-grade gear, has every reason to explore video from DSLR or mirrorless type cameras, such as the AS7.

On FAA proposes regulations for commercial drone usage article (119 comments in total)

Drones like the AirDog are designed specifically to fly over people and track their sport antics by camera. The owner will not always be alone on the ski slope, road, bike path, or wind surfing area. Some people also envisage lofting drones over games, parades, or even weddings. Safety factors not easy to reconcile.

Then there is the temptation factor: drone flight over an empty field probably gets tedious in a hurry. Old fashioned R/C planes were at least more challenging from the purely navigational standpoint.

Amazon to deliver goods by drone? A hoax. Even if hypothetically feasible, ahis would never be economical or safe, any more than travel by jet pack or flying car. First let's see if they can engineer driverless cars or delivery trucks.

On CP+ 2015: Canon shows off prototype 120MP CMOS sensor article (255 comments in total)

"[G]eared towards video production"? In the Rebel T25i or 5D Mxiv?

Direct link | Posted on Feb 13, 2015 at 17:06 UTC as 36th comment

Phantom DJI "support" for a m4/3 camera would require a rather large drone. Not quite a Bell UH-1, but perhaps almost as noisy, until it crashes, plops in the river, or gets intercepted by someone answering an irate 911 complaint.

Hey, Canon, nice to see a Rebel update. OK if video a back-seat feature. Now, ur [cough, cough], how about a 4k update for the VIXIA HF G30?

In reply to:

kodakrome: New 24 MP sensor and upgraded AF? Sounds like a nice, capable camera. Rebel cameras are all about hitting price points that a lot of people want and need to be in. Calling a $1,000 camera a "beginners camera" is no different than calling a $30,000 Honda a beginners car just because it's not a BMW. It's just silly.

Canon is perhaps the Toyota: 1D the Lexus, 5D the Avalon, 7D the Camry, T6 the Corolla.

On Hands-on with Samsung's new NX500 article (343 comments in total)
In reply to:

jkoch2: Like the NX1, the NX500 appears to offer h.265 HEVC video format only. This uses less space, and allows use of slower memory cards, but the savings are small compared to the current hassle h.265 entails in terms of saving or editing. Widespread support will come only slowly. Which 2015 Galaxy tablet can play the 2006-vintage AVCHD codec? It would make great sense for Samsung to: 1) offer other video format alternatives in the NX1 and NX500; and 2) disseminate cheap or free plug-ins and players to enable multiple devices and editing tools to work with h.265 directly. Samsung's deafness on the matter is stunning.

Transcoding to h.264: processing time, extra drive space, IQ loss, and begging the "why h.265" question. SDXH U3 cards don't cost that much. Most other cameras offer two or three video format options. Samsung could at least offer one besides h.265.

In reply to:

The Squire: I'm looking for a 4k-capable ILC this year. Going to wait to see if sony's top-end APSC e-mount is 4K, then make a call. Maybe by then there'll be better support for HEVC workflow.

Sony favors the XAVCs format for 4k, and has not been eager to confirm whether the a7000 4k will be internal. Samsung's initiatives may compell Sony to add internal 4k, but perhaps stick to XAVC, at least until the h.265-based 4k Blu-ray product materializes, if ever.

On Samsung introduces NX500 with NX1's 28MP BSI sensor article (143 comments in total)
In reply to:

nerd2: Wow, native 4K video / 28MP BSI sensor / 9fps with hybrid AF? /Full flip up AMOLED screen?

It just dominates every other non-FF MILC offerings... and it's almost a steal at $799 with lens.

Mike99999: whose photos suddenly become "Olympic" because they spent over $1,000? Conversely, a "pro" with an NX500 might outshoot what "hams" get with FF. O' course, 4 billion smart phones will out-shoot and out-perform the whole pack.

On 3,200MP LSST camera gets construction approval article (257 comments in total)

More proof that phone cameras rule the universe!

This big sensor requires the light of supernovas, or entire galaxies, to register, and they remain flared specs or blurry. "Interstellar dust" is a astro-babble for noise. No burst mode at all, and the light received may be centuries or millennia old.

Meanwhile, with no more illumination than a 65 watt bulb, an ordinary phone camera yields a fine image of a cat one can Instagram from here to the next star and back before the big rig is even complete. Contest won.
