On article Panasonic Lumix DC-GH5S First Impressions Review (327 comments in total)

Might the "intended users" of the GH5s include people who currently use the (5-axis IBIS equipped) a7sii? Let them be the ones to do the tests, comparisons, and assessments.

As for anyone else, who would ever give up IBIS, only for the sake of higher usable ISO, and for $500 more, yet still have the same lame AF? Better to keep the IBIS and get a faster lens to aid low light results. A mere $500 will buy a 4k LX100 with an f/1.7 24mm equivalent lens.

Alas, it seems there will be no (dust sealed, BSI sensor, 5-axis IBIS) LX200.

Irakly Shanidze: I wonder why they keep making it in a form factor that is not at all convenient for video. Being a direct competitor to BlackMagic Production 4K camera one would expect more video specific design.

If cameras lack IBIS, and are intended to be used on a tripod or in a "cage," why does the "form factor" matter?

On article How to photograph the northern lights (80 comments in total)

The camera gear and settings are feasible. To attain the necessary latitude settings, however, can be expensive and chilly. The nights may be long, but cloudy. The short days in between shots must be very dim and bleak. Unless you live near the poles, air fare to Iceland may make it the most affordable option. Odd that no UK/Scot locations are listed.

On article Shooting with the Olympus OM-D E-M10 Mark III in Moab (124 comments in total)

Why not use a Moab visit to promote Olympus' Tough and action cameras? An OM-D is not easy to use while biking or rock-climbing.

Poor bear! Barely any sympathizers. But what to expect from DPR gear heads? Most are ursine bruins. All growl, no glimmer. All claws, no cuddle.

Had the subject been "Starving Photographer," the responses would have drawn similar jabs and denial: the "cooling market" is a hoax, the loser had no talent, he was only a "soccer mom," he failed to upgrade his gear, he had some (perhaps mirrorless camera) disease, or (like any martyr) he is better off dead. The proceeds from his gear? Bare bones!

Even with political will, no quick reduction of CO2 levels, or restoration of "normal" polar temperatures and ice would be feasible. The polar bears' plight is fragile anyway, since they must forage extensively, compete violently, and their habitat is dark and forbidding for months on end. The best hope for survival might be a conservancy that fences 250 bears into "pastures" with ponds stocked with fish they could catch and eat. The annual cost would be less, and the impact more tangible, than quixotic lobbying to alter world ocean temperatures..

What images of "critical US assets" would DJI be obtaining that are not already available, in superior form, from public satellite maps or "street view"? By treaty, RU flew reconnaissance plane over Trump's NJ club, and the US has reciprocal rights over RU territory. DJI's "no-fly zone" mapping may be more comprehensive or user-friendly than the FAA's or other pay-to-see services. But designation of defense-sensitive zones would be a clue to which places to watch via satellite. Aircraft carrier flotillas are not hard to detect from space. The PRC's military UAV program may indeed surpass any rivals'. Might it be strong enough to enforce a no-fly zone over a defense treaty partner on a critical nearby peninsula? Besides, all the major potential adversaries have SBBMs, so no side would really "win." Extreme caution advised. But any threat from consumer drones is a distraction.

In reply to:

tinternaut: In a nation where some some fifty two percent of citizens have been diagnosed with Dunning-Kruger, I think a little regulation of drone usage is a good idea. Drones are often a public nuisance and more than just a danger to aircraft.

Dunning-Kruger is very evident at levels of command far more lethal than hobbyist drones. Claims of being "I am really, really smart," or "I know more than generals" are suggestive. But formal diagnoses, even if they existed, might be dismissed as "fake" or penalization of competitive self-esteem. The meek are to "inherit the earth," but not the one we know.

Suave: Ten years from now drones will be allowed to taze police officers illegally interfering with their operation.

Not quite. More likely: police drones will bark "You're under arrest!" at anyone "suspicious." Any who flee, resist, or who appear "darkly threatening," will be tazed, maced, or shot. Relatives of the well-to-do will be dismissed with apologies. The "other people" will pay fines, serve sentences, and be registered on a permanent database. Hardly any different, though, from the present. And so many perceive any camera, even at legal distances, as "interference with law enforcement."

Magnificent that Mr Falangas gave clients a "rainy day" provision, going all the way to Norway, at no extra charge. Or was there a charge? Ahem... There might be two terms: 1) on site, with 4,000 miles travel, plus whatnot, good heavens; or 2) a PS job with stock shots, still priced well. Mr Falangas' shots or video of the 14-hour hike might be exemplary. Dare he share? Marriage often resembles a very trying hike: 10% inspiration, 90% perspiration.

Dean Holland: Be honest - who’s here for themselves, not for presents? I’m guilty.

It is difficult, even ill-advised, to buy camera gear for other people any more. People in general are happy with their phones, or want a new one, and it addresses all their photography or video needs. The enthusiast, meanwhile, is difficult to please. Even if Santa gets the wish list, the replies may be: too expensive, not the right version in stock, or "The Mrs. decided new socks make more sense."

Quite a gamble. And not just because the groom could lose his balance. Norway has more rainy, foggy days than Long Beach, CA. The couple could have waited for a sunny day at Long Beach, posed for some pictures, and told everyone they were taken on the actual date.

chida: Come to India. You have thousands of locations, different from one another, culturally, geographically, historically, climate-wise, etc. etc.

1-star hotels or restaurants in Norway probably cost about the same as 4-star versions in India. Norway is near the top of the "Mac Index" comparisons. Flight to India may be another matter. In some circles, marriages also involve a rather huge dowry. To rent an elephant for the wedding picture can cost several years' worth of peanuts too.

Think of all the salt water spray, so friendly to camera gear! You cannot sail a Laser seriously and not get plenty wet. What was the second craft used to take the pictures?

Much of the credit should go to the anonymous "boatman" who enabled McDonagh to get near sailor Murphy's craft multiple times without disturbing the shots with bow waves or a collision. The subject had to steer her craft suitable to the wind and waves, with only limited discretion to "pose." As much as some will object, this is also a case where a drone might be handy; however, it is hard to fly a drone close enough to the water, and the usual videographic preference for slow shutter speeds would entail much blurrier results than those obtained with the speed sync.

A $15 million 3-month profit is certainly better than a loss, but the annualized return on GoPro's $825 million equity would be only 7%. Will final quarter results be enough to offset the 1-QTR-18 seasonal dip?

According to GoPro's 10-Q SEC filing, R&D expenses were cut from $266 million to $177 million for the nine months ending 30-Sep-17. That might be hard to sustain, unless R&D efficiencies improve dramatically.

The balance sheet includes $146m in "goodwill," a good share of it originating in the 2016 purchase of two mobile editing application firms (Quick and Splice) at prices nearly $100 million above the tangible asset values. There was no amortization charged YTD for 2017. The SEC filings furnish no break-out or discussion of the actual contributions to recent earnings. Is either app attractive in practice?

Age discrimination? Oral hearsay is inadmissible. Written evidence seldom exists. Written HR policies, anywhere, usually disavow it. Age need not be mentioned at all. A hiring manager, with 7-10 years experience, will almost always look for candidates with a junior experience level. If an applicant has 15 years experience, instead of the 3-5 years prescribed in the ad, he is simply "over-qualified" or incapable of advancement. Anything before 2007, when the hiring manager's career began, is either irrelevant, stale, or an annoyance. If there are wrinkles (time gaps) or bald spots (date omissions) in an applicant's history, no need to consider further. Odds are there will be more than enough fresh applicants with the desired experience level and no gaps: the "good fit." HR will nod. All legal. Works by tidy algorithm. With no shades of gray!

On article WiBotic PowerPad brings wireless charging to drones (12 comments in total)

Instead of putting a drone on a charging pad, wouldn't it be quicker and less immobilizing to swap the drone's battery, so it can fly while the first battery is re-charging? This would also be a faster way to keep an eCar on the road too.

Any charger must, at some point, be wired to a power source.

rsf3127: NY Times is so irrelevant...I am pretty sure that without Soros funding them, they would already have filled for bankruptcy.

The NYT Co. has reported profits for 2013-6 and for the first two quarters of 2017. It has net worth of $887 million. This is public information. Just look up the NYT ticker at any financial information website and review the financial disclosures.

People aspire to the sorts of wildlife shots they see on TV. Such work often requires months to make and, very likely, employed all sorts of means to get close to the animals, far from roads or conveniences.

A typical visitor has one or two days. Pictures of elk 300 yards away will look flat and uninteresting, even with a 400mm lens. A distant bear may be largely hidden by brush. The folks back home will yawn at anything less than a selfie close-up with a trophy beast at kissing distance. That is what people see in the Nature shows sponsored by Canon. So the motivation to approach the animals is palpable. Any rules will be scoffed. Any who comply must settle for pictures that include the scoffers. Possible alternatives: 1) zoo, 2) game farm like the one DPR visited, 3) tricks with green screen and Photoshop, or 4) postcards.

It could be worse. A "safari" used to mean (or can still mean) to gun down and behead or skin as many big beasts the customer could shoot.

If the comparisons tell us which camera or sensor were involved, partisan observers will find a reason to praise the one they already favor by faith or fancy.

The best tests would be "double blind," where the judges and people who score the findings have no knowledge or tips about which camera's shots they are seeing. Good, too, if the judges include a group that has no clue about sensor size disputes anyway, but only "know what I like." Very likely, there would be no statistically significant difference in the scores, or it would be driven by factors other than sensor size: content, color balance / saturation, lighting, lens, editing, or audio. A skilled photographer will know how to get good results with almost any device. Most often that will be "the one you have with you."
