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.

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).

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.

"[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 (347 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.

On Samsung NX1 First Impressions Review preview (1444 comments in total)

Cyberlink PowerDirector 13 supports HEVC h.265 video files. It is also inexpensive and easy, but with lots of competitive add-ons. Others have stated this already, but without any acknowledgement or test. The wall of denial and incomprehension is rather obtuse. Give credit where due.

An improved Adobe h.265 plug-in may be around the corner, but cost a fair sum. Neither Sony (Vegas) nor Apple (FC) are likely in any hurry to benefit a Samsung camera. Within a year, h.265 support should broaden, but require strong CPU/GPU spec.

On Samsung NX1 First Impressions Review preview (1444 comments in total)
In reply to:

Trk: I see that dpreview very clever built advertising article brings its fruit and readers already think that its better than full frame camera.
Samsung NX1 is of course good camera but not for this money and not in low light where its dynamic range quickly degrades with increased ISO. Do you really think that this camera is better than Canon 6D (which maintains its dynamic range also in low light)?

Also do not forget how Samsung works, once this camera is released they will loose their interest to support it, this is how they work. Release product, sell it, make cash and go on with new product next year. They do not even fix critical software bugs reported to them.
There is no technical contact, no support, no Samsung forums, no nothing. Only some strange chat which will never answer anything or solve any issues other than RMA camera. After this camera is discontinued, replacement parts will not be available and you can throw it into trash if nonfunctioning.

Trk: so every NX1 firmware update is proof of "no support"?

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

Some optical questions:
1) won't the near space (<10LY) dark objects clutter or fog perception of more distant ones?
2) at what distance does it become difficult or impossible to deduce the linear "direction" of a moving object based on reflected light?
3) how many specs will prompt "cry wolf" / "doom is near" warnings and then turn out to be mis-calculated?
4) Isn't the sensor useless anytime the moon appears or as nearby towns (La Serena, Coquimbo) increase street lighting?
5) Won't it be more efficient to loft a Hubble II, with a somewhat smaller sensor, into space itself?
6) Won't phone cameras with "rafts" or arrays of 1/4.0" sensors soon give them IQ comparable to many DSLRs?

On Canon's Q4 earnings report shows camera sales are down article (315 comments in total)

If one compares the 2014 operating profits, relative to sales, of the imaging segments of Canon (14.5%), Nikon (4.8%), Sony (11.3%), Oly (-8.3), or Fuji (6.3%), Canon is still king of the shrinking hill. Canon can't make the world buy more cameras, but it will stay in business so long as it outperforms its competitors where it counts. If not the smartest camera company, then certainly the least dumb. Canon's edamame-counters are doing something right!

On Canon's Q4 earnings report shows camera sales are down article (315 comments in total)
In reply to:

jkoch2: Canon is doing exactly what it should: pare back P&S production and costs and stick to its knitting in the DSLR world. It will roll out fewer, and more modest changes. The market will shrink, but Canon will retain a strategic share of that smaller market. Sales and earnings will diminish. Reward shareholders with greater dividends or buy back stock. This will rebalance the return on equity to a competitive ratio.

The worst thing Canon could do is try to make a DSLR into a smart phone. Won't work. Easier to make an elephant fly.

"Make the perfect camera" is not possible either, since that just may turn out to be what people find in their smart phones.

Plenty of daring innovations have already been launched by others. The NX1, CM1, a7s, OMD, and even the Lytro are admirable in their own ways, but none earn their makers heaps of dough.

Sometimes the best thing to do is avoiding the dumb. Do what you do well, not what you don't. Oh, and printers are doing OK.

Canon's imaging segment reported Y58b operating profit on Y401b sales, for the December quarter. Sony reported Y20b operating profits on Y178b for the Sept quarter. The margin was 14.5% for the both the quarter and the whole year. That's better than Nikon's 4.8% margin or Sony's 11.3% margin for the Sept quarter.
