About me:

My large collection of Canon FD lenses is back to life. Thanks to mirrorless cameras and adapters. I particularly love the FD 35-105mm w/macro, f/3.5, which is well known for its clarity and sharpness, and the FD 50mm, 1.2, L.

BitchCoin is more fitting.

tabloid: What makes the police nervous in the US is the amount of guns that everybody has.
Guns killed over 13,000 people in 2015. (US)
There are 300 million guns in the US.
As for the UK...there was 8 deaths from hand guns in one year.
No wonder the US police are nervous.

I'm wondering if Nikon was getting advice on what battery to use from Samsung's phone division!!!

Krich13: I've had this 35/2 lens (sold under Viltrox name then: https://www.amazon.com/VILTROX-F2-0-F16-Standard-Prime-camera-support/dp/B01MTKE4V2 ) , then sold it for $50 on ebay.
Build quality is much better than expected (and it has a built-in hood!), but very soft corners on Sony A7. Actually, at equal apertures the sharpness could not keep up with Canon nFD 35/2.8 (granted, only f/2.8) , anywhere in the frame (comparison in the corners was almost laughable) and that's a 30+ years old design!
Jim Kasson tested it as well: http://blog.kasson.com/the-last-word/a-dirt-cheap-fe-lens/ . Same conclusion: good center, bad corners.

I have been using my Canon FD and nFD lenses on my Sony a6000 for a whie.
That includes a 35mm f/2, a 35-105mm f/3.5 macro, a 50mm f/1.2 L, and a Canon FD 500mm reflex lens, to name a few.
Really happy with the results.

Firearms were used to kill 13,286 people in the U.S. in 2015, excluding suicide.

Although I have been a gun owner throughout my life, the argument that "guns don't kill people, people kill people" is the most ridiculous, most ignorant, and most stupid argument one would ever hear about this subject. This is what the NRA washes the brains of some people with.

Without guns, those 13,286 people would have been alive. Maybe some broken nose, or a few scratches over their bodies.

Gun laws need to be overhauled so they are not freely given to criminals.

sh10453: Very interesting. Elaborate work (4 to 5 hours)!

I probably would do it differently, with much less bulk, and won't be so intrusive.
A quarter inch thick rectangular copper plate, with a sheet of thermal tape, of the same dimension, sandwiched in between, would do the trick.
But that would be too simple, takes just a few minutes, and would not make it to DPR News or YouTube.
A couple of defective PC processors for less than $5 mounted backwards, with the thermal tape would also do the trick, and would take just a few minutes, mainly to bend the piano wires. But I prefer the one piece copper plate.

Thanks, but, on one hand, I don't have this camera, and, on the other, I use a video camera for videos, so I never encountered heat issues.
I threw the ideal in case someone wants to use a quick, simple, and inexpensive cooling method.
Copper is more effective than aluminum for such application (dissipating heat).

sh10453: Good job Carey. I'd leave the selfies to the smart phones, though, because they don't serve any rugged testing purposes, but that is me.

As for the wish list, I also add my voice to 1" sensor, aperture priority option, and full manual control option, but I wouldn't want to sacrifice the zoom range.
Thanks for this review.

With a 24mm lens on a rugged camera, and long arms, one can now include the tummy and the big belt buckle in the selfie, not just head and shoulders :-)
That's what a rugged, waterproof camera should be. :-)

For travel, I like the tiny Panasonic LF1, with its 1/1.7" sensor, viewfinder, and wi-fi. It slides easily in a shirt pocket, Leica lens, and the 200mm zoom is awesome.
Thanks for the humor.

Ben O Connor: Folks! There is a usb-c to 3.5mm mic adaptor from gopro!!!! Would it work for Lumix cameras ? Has anyone got any experience ?

(Gm series,Gx series etc...)

You have a better chance getting an answer if you ask this question in the Panasonic forum.

In reply to:

OlyPent: To add; there is flexible heat-sinking compound (not sticky) that will markedly improve heat transfer if placed between the heatsink and whatever it is attached to. Better than what must be about a 50/50 contact/air gap here.

Thermal transfer TAPE would be far better than a compound for this situation.

On article SainSonic launches 50mm F1.1 lens for APS-C cameras (243 comments in total)

Sounds like a winner to me. Good start, but there are too many players in the 50mm lens market, although not in the f/1.1.
I hope they come up with good zooms soon, like 16-35mm, and 24-105mm, and keep their prices sane (or "Sain" :-) ... ).

sh10453: Some people seem to minimize the issue.
You can't compare a drone with a bird. A drone has metal and plastic parts. More critically, it has a battery that can explode and start a serious fire if it is swallowed by the aircraft, and bring the aircraft down.

At the engineering department, University of Arizona in Tucson (my alma mater), a team of engineering students (sponsored by Raytheon) are working on a project to deal with annoying drones.

Team's leader (a senior systems engineering student) says " ... project would let everyday consumers disable commercial drones autonomously, safely, and legally".

Maximize the page (square at the lower-right corner of the window) to read the short entry in the Arizona Engineer magazine, if desired.

https://issuu.com/azengineering/docs/2017_spring_azengineer_final

The short article doesn't reveal much, (probably for security reasons) so I can't comment on what exactly they are doing, whether it is destruction, jamming, commanding the drone to return "home", or any other action.

I'm sure that legal teams from both, Raytheon and the U of A, are involved.
There is no doubt that Raytheon, and other similar defense industries, are not clueless or sleeping with regard to CN and RU.

Hard lessons were learned after Iran grounded a US drone a few years ago.
The cat and mouse game in the defense area will go on for at least our lifetime, with measures, counter measures, counter-counter measures, ....

In the commercial use, if Amazon can deliver our orders using a drone right now, perhaps in a decade or so there will be no pizza delivery boys anymore. Drones will deliver the pizza, hot from the oven! No tips for the drone either!

That's a very impressive performance under such stress test.
Under normal use, this camera shutter should be able to perform for a lifetime (at least for most users).

sh10453: Fan Edition? Does that mean it comes bundled with a Fan? So we have to buy the optional heat-sink? What size fan?

Samsung makes great products when they work, but don't count on their terrible customer service when something goes wrong.
Speaking of customer service, ...
I recently had to deal with Huawie for an issue with my Honor 8, which resulted from Android site pushing a Beta version of Android 7, which was a disaster.
Within about 48 hours from contacting Huawie's customer service, I had a new, replacement phone in my hand.
Everything was over-night shipping.
I was really impressed.
Samsung can learn a lesson ... or two.
Their other big disaster was quietly, ungracefully, and silently abandoning their camera business, leaving customers with no answers, no comments, ..., nothing..
Personally, Samsung has lost my (and my family's and friends') business because of the poor customer service.

I have multiple brands SSD's on multiple PC's, including Samsung 850 EVO Pro, Micron, Crucial, Lite-On, and OCZ, all in the 500-525 GB range, with a 1TB 850 EVO Pro on its way in the mail right now.
So far, I haven't noticed any difference among the brands.
They all have been fast and reliable so far.
Of course performance is also dependent on motherboards, RAM, and processors.

Mount these cameras on a Mexican sombrero. It's a lot lighter and cheaper :-)
