On FAA proposes regulations for commercial drone usage article (119 comments in total)
In reply to:

Lee Jay: The drone risk to aircraft is exceeded 10,000 to 1 by the bird risk to aircraft. The drone risk to privacy is likewise drastically exceeded by binoculars and long focal length cameras.

To put it mildly, drones are a way lower risk to your happiness and health than some people make them out to be.

Neither do drones.

If someone wants to spy on you, there are far less obvious ways than hovering a quadcopter with a fisheye camera on it a few feet from your house. Like binoculars.

They're very quiet. Much, much quieter than a flock of geese, or a car rolling 25mph, for example.

On Opinion: Canon EOS 750D and 760D article (316 comments in total)
In reply to:

mgrum: "Canon has never offered us two cameras with the same sensor and asked us to pay more for one, to get some extra features before"

That's pretty much all Canon have done for the past 6 years ;)

That isn't true either.

100D and 700D
60D and 600D
40D and 1000D
300D and 10D
20D and 20Da
60D and 60Da

And then there were all the "N's" like the 1DIIn and all the Rebels from the 550D through the 700D which were all very similar, all had the same basic sensor, and most or all were available at the same time.

Yeah..that was a strange comment. How about the 7D versus the 60D versus all the Rebels with the 18MP sensor?

Thank you!

Joins other masterpieces: 17mm PC (wow!) and 8-15mm Fisheye zoom (another wow!).
Well done!!

Add the 100-400L II:

I like number 2 since I like airplanes. Number 10 is just disgusting.

I don't care much for "eye candy" but I like number 9 because it shows something happening.

On Adobe details OS support for next version of Lightroom article (228 comments in total)
In reply to:

iAPX: I am awaiting for better performances for LR6 on OS X (actually using LR5 on OS X 10.10 Yosemite).
- using more than 4GB of RAM (checked on a 16GB and 24GB configurations that I use everyday)
- using hyper-threading, still it seems limited to number of PHYSICAL cores, thus not taking account the work Intel did to make hyperthreading really efficient (4-core w/hyperthreading vs 4/-core w/o)
- using multi-threading and overlapped IO to speed-up Exports (actually you have to launch many parallel Exports to try to feed the fast CPU you pay for!)
- using the GPUs for RAW decoding and processing, even if it's an opt-in option (openCL developer here!)
- working correctly on retina display, not hiding the "loading" label while it's displaying a non-retina image, and awaiting seconds to have the true retina display to be done. (iMac Retina)

LightRoom seems to be based mainly on old Photoshop CS4 or CS5 base-code that is mono-threaded, except for some filters.

The vast majority of LR users do use the cataloging functionality. Also, a great many LR users use it INSTEAD of PS and therefore don't need to own (or rent) PS.

Lightroom isn't based on PS code at all. It's largely written in a different language. Hyperthreading wouldn't help much.

On Fujifilm announces new rugged and long zoom compacts article (28 comments in total)
In reply to:

thx1138: 1/2.33" sensors should be banned. Can't believe we still see this crap in abundance in 2015.

They're also useful for cameras that fit comfortably into your pocket. I really find 25mm to be about my limit and the 1/1.7" compacts are more like 29-32mm thick. The smaller sensor makes for shorter focal lengths and thus thinner cameras. And they still crush the best cell phone cameras.

In reply to:

Nick8: Greetings everybody,
Does anyone know why different manufacturers are using that type of protruding design for their underwater camera lenses? For me it looks very odd.

Because the lens zooms back, into the body. It's entirely inside the camera covered by a window on the outside.

dash2k8: Outsell? I actually believe it. Mirrorless will be more appealing to the masses. Ma's and pa's looking for simple family photos will prefer the smaller, lighter and more portable options. And honestly, mirrorless is closing the performance gap to make it good enough for most consumers. Pros will never outnumber amateurs so I don't see why people don't think mirrorless will outsell DSLRs. I also don't understand why ppl are upset at this eventuality.

I think mirrorless is better for manual-focus situations, and that's about it.

In reply to:

CameraLabTester: When consumers (not professionals) consider SIZE as a major factor: MIRRORLESS will kick in.

Oops! It already has!

PROS: big and bulky

CONSUMERS: small, comfortable, and wise. (smart too)

.

One of the most severe pains I've ever had in my life came after using a camera that was too small for my hands non-stop for about an hour and a half. I hadn't realized it while I was using it but my hand had cramped around the tiny grip. I had to pry my fingers open.

I've used properly sized SLRs for 12 hours straight without an issue.

Same thing as wearing shoes that are too small - they hurt.

It's not hard to understand - a camera grip is like a glove for your hand or a shoe for your foot. It should fit. Smaller is NOT better, it's worse unless you're only going to use it for a few seconds.
