chshooter: Once again very US specific news. Not everyone lives in the US. It is a pity to see that DPreview has become pretty much US exclusive (although a natural development)

Actually, Phil started DPReview in London. Most of his sample galleries were shot near the Tower Bridge on the banks of Thames.
Phil cashed out by selling it to Amazon, which moved it to Seattle later.

M Chambers: In theory it's legal but depending on the specific actions of the photographers it can be considered illegal if the activity is harassing or obstructing. Also note how this is only in federal court. States, counties, and cities, have recently passed laws making the mere act of photographing the police illegal. I'm no saying I agree with those laws but people shouldn't think that this ruling means they won't get in trouble.

In these cases, the federal circuit courts interpret the US Constitution, which overrides all state and local laws, not just federal laws. Of course, the ruling each federal circuit court only applies to its territory (the 3rd circuit here only covers PA, NJ & DE), but their decisions set a precedence that all other courts respect.

The most important skill is timing. You cannot pray and spray at 10 frames per second. The flashes need to cycle between shots.

brycesteiner: Strobes and flashes are not allowed even in high school sports arenas, at least not in Ohio. Specifically forbidden in the state rules as it could be problematic and can be used for the opponent's fans to distract another.
If the pictures were better it would be interesting use for certain.

You can see flashes going off whenever someone go for the basket at NBA games on TV.
In Staples Center in LA, there are 8 channels of remotely fired flash sets, each with 4 strobes high above four corners of the court.

Saurat: So one can fire off srobes in the faces of 7ft tall basketball players during a pro game possibly leading to a missed shot?

The flashes are from the top, not on the camera.
You can see the flashes even on TV, whenever someone attacks the basket.

Too bad. You can't make a film camera this way.

Old Cameras: "Settlement" implies it never went to trial, which is unfortunate. Something tells me that no wrong doing was admitted, just a wad of crumpled cash offered up to make it all go away. They needed to be judged and found guilty with a prescription for change.

The county government spent tax payer's money to make this problem go away.
I wonder what happened to the police officer. They should at least deduct that money from his retirement pay. Since the county did not admit any wrong doings in the settlement, they cannot turn around and punish the police.

The county now has a new set of policy on public's right to take photos. That means money spent to train everybody. At the end, everyone from other police officers to the tax payers lost, except the bad apple.

More bulky than a DSLR.
Drain battery as fast as a mirrorless.
More wear on the shutter.

Mister Joseph: Very nice, how much?

Samsung's consumer grade 850 EVO series 2 TB currently sells for $750. The 16 TB drive here is an enterprise class with 8 times the capacity. It will sell for > 8 times the price. You pay a lot to be on the bleeding edge.
My guess is > $8K.

I signed up using my Facebook account.
I first tried to transfer my Facebook photos. It transfer only 1 album (my oldest).

I then tried to upload photos taken at a recent party, hoping to save the time to email them. As it turned out, there is no way to make them public. My friends cannot see them unless they log in as me.
I picked 28 photos to upload from its web interface. Only 26 were loaded. Since all the photos were mixed with my Facebook transfer, there is no easy way to identify what was missing. I created a new album and move them. But this new album ended up with only 23 photos. There is no way to see photos NOT in an album. Managing photos is so primitive.
BTW, it cannot identify the lens used as the 24-105L.

On article Will consumer DSLRs be 'dead in 5 years?' (143 comments in total)

Will DSLRs be killed by mirrorless, or BOTH of them will be killed by smartphones?

Current DSLRs are better than mirrorless in two areas, phase detect AF & real time optical VF. With better electronics & software, mirrorless will catch up on both areas in less than 5 years.

Consumers always favor convenience over picture quality. The current boom of DSLR is not normal. Back in the film day, consumers bought a lot more Kodak Instamatic cameras than SLRs. The SLRs had a short boom in the late 70's starting with the Canon AE-1. When 35mm P&S offered AF, consumers went back to the smaller P&S. Meanwhile, Polaroids sold well because it was fun passing photos around with friends.
Smartphone are today's Polaroids, except their photos are a lot better. They are killing off cameras, starting from the small P&S. The big full frame cameras (DSLR or mirrorless) will survive. However, without the profits from consumer DSLRs, the development of lens & bodies will be reduced.

Rod McD: Human filing cabinets. Not a leaf to be seen. Sad that it's probably the future in many places.

I would rather have tightly packed, efficient living space so as to leave more empty lands as wilderness, than boring suburban sprawl where everyone has to have a front lawn, a back yard, a 3-car garage, and a 3-car driveway.
Given the same number of people and same area of land, what would you do with your land?

lattesweden: Are you allowed to publish some one elses (the theifs) pictures taken on your stolen gear or is it copyright intrusion from a legal point of view?

"Eavesdropping, wiretapping, invasion of privacy, voyeurism, etc. " are based on expectation of privacy. How much privacy the thief can expect when using someone else' phone with all the apps still installed?

LarryK: Rambus is not so much a technology company, but rather a patent lawsuit mill.

Best to walk away from anything they develop, it's likely just something their attorneys will use to sue people.

Rambus does not spread technology by licensing it. They look for technology similar to theirs and extort $$$ from innovators. They call this licensing, just like mobs selling "protection".

It will be perfect if you level the horizon and adjust for vertical perspective.
