Lee Jay: For the video I do every year, I need this:

24-85 equivalent zoom range.
1.5 km range line-of-sight.
90 knot maximum speed.
1 hour flight time.

I've been using a Bell 407 and a Canon 80D with 15-85 or 18-135.

I have multiple R/C aircraft that exceed 100mph. The actual limit is 200mph, but currently only for jets:

Sec 336: ... "the aircraft is operated in accordance with a community-based set of safety guidelines and within the programming of a nationwide community-based organization;"

CBO rules:

"For RC fixed wing aircraft: The maximum velocity will be 200 mph."

505mph R/C glider: https://www.youtube.com/watch?v=hFPJ6DUAY10

Undoubtedly, but it also can't do the job I need done. And it may not be cheaper overall, since I only do the flight once a year.

Lee Jay: f/352 (I think) is the tightest I used. It was a 17:1 macro. And, yes, now I know better.

The exposure time was 1/250th, because the subject was illuminated by a 580EX from close range (like a foot).

SSDs are still costing 6-12 times as much per GB as spinning drives. I was hoping this would have come down by now but it seems to have leveled off.

Still using an SSD as an OS/app/catalog drive and a 4TB spinning as a data drive.

Lee Jay: To me, the whole point of an ILC is FOCAL LENGTH RANGE. Wake me when a decent cell phone has something even resembling decent focal length range (i.e. 24-100). And even that would be insufficient for travel. For that, 16-400 is nice, but 180° horizontal to 640mm equivalent is what I usually use.

Had them for at least 11 years. Still waiting for any sign in a phone.

ojos azules: If you like liveview go all in for Mirrorless.
Applies to dpaf also.
Mirror down = sucks.

What if I don't like "liveview" (i.e. not-quite-liveview)?

stevo23: Drop the drones. Shotguns, nets, jammers, whatever it takes. I'm getting tired of this aggravating noise pollution. They have their place, but when they have invaded so many of the places we go to for peace and quiet, it's time to kick them out.

I work in a facility that's so rural, the shipping companies can't decide what city we're in.

Electric models are close to silent for the most part. When I'm flying at my field, I can usually hear the highway a mile away over the planes that are within a hundred feet or so. And there are so few "drones" that it's really only a made-up issue.

Comparing a near-silent electric model to a ship's fog horn shows how dumb your argument is.

PerL: I totally I agree. I have just added a DJI Spark – IMO it hits a critical sweet spot in terms of price, size, weight (just 300g), IQ and ease of use. For video drones are already a standard tool, but I think now it shortly will be in ambitious photographers bag, and definitely in the bags of the pros. It will be expected that they can take drone shots.

Well, I think DJI is about the last thing I'd buy due to their unilateral enforcement of dead zones. My house is in one.

If only they had the still capabilities of a 6 year old pocket compact - 12MP and a halfway decent zoom range (16-50, 24-100, or something).

The utter stupidity of people never ceases to amaze me.

As far as noise pollution goes, better ban cars and full-scale airplanes first, since they are a far, far, far greater source of noise than electric models.

After 30+ years of being an active model airplane builder and flyer and 40 years of being an active photographer, I just can't get excited about helicopters, single or multi-rotor. I last had a camera on a model airplane in 2002.

Every time I go look for a "drone" (horrible term) that I could use for photography, it's either not available with the features I want or it's outrageously expensive (i.e. 5 figures). And every time I fly my small helicopters and quads, I get board after a few minutes. They just aren't fun to fly for me.

quadraticadder: Drones are being regulated into a costly no fun zone.

I have 2.5 million dollars in liability insurance through the Academy of Model Aeronautics. It includes many other benefits including the magazine, club support, scholarships, and so on. All that is only $75 a year precisely because model aircraft are so safe.

In reply to:

Lee Jay: Even a high-end photographer uses the term "focal compression" which is at best meaningless, and at worst, entirely wrong.

The "compression" comes from being far away, not from using a longer focal length. The focal length is a result of being far away, but it's not a cause of the foreshortening effect. The shooting location is.

Better to be a wise ass than a dumb ass.

Oh boy...he said something in that interview that is practically blasphemy on DPReview - he likes crushed blacks with all the detail wiped out. That alone could cause a mushroom cloud in some circles around here.

All you need to add to a current smart-phone camera to make it usable for me is:

At least a 24-120 equivalent zoom range.
At least f/2-f/5.6.
A Xenon flash.
A 1/1.7" or larger sensor.
An eye-level viewfinder.
Decent ergonomics.

That's it. Nothing much.

In reply to:

Old Cameras: This is why we can't have nice things.
A drone could damage or take down a plane, its deadly dangerous. All so some jackass with no respect for rules can put pretty pictures in his website. Throw him in jail, fine him heavily and crush his toys. Fire fighting is dangerous and dam expensive.

The probability of a crash during such an operation is higher from practically every other possible cause than from the models, probably including what they ate for breakfast. And, again for the reading-impaired, that doesn't excuse flying where there's a TFR forbidding it.
