On article Don't fry your sensor if you're shooting the eclipse (25 comments in total)
In reply to:

Suntan: FWIW, I shot the eclipse, wide angle, with two different cameras. Neither had filters. Both are fine.

You didn't use a 400 f/2.8 lens for six seconds, presumably because you are not an idiot,. :)

Karroly: Hopefully, today, some pictures can be instantaneously sent to the Cloud...or to someone else's smartphone nearby who does not look like a pro photog and will not be arrested by the police... :-)

Something SnapBridge is actually good for :)

dustymac: I'd like to put in a plug for TSA Pre-check. My wife and I had FBI background checks a few years ago and for the last couple years it's just been showing up on our boarding passes automatically. It's real sweet: no shoes off, no belts off, no laptops out, no body image X-ray or pat-down. Five minutes tops. And since we're usually late to the airport, it's saved our butts more than once in making a flight.

All that said, and at the risk of getting a visit from the FBI, there is something wrong with this country. On our last trip I watched a young mother get a full pat-down in front of everyone with her two kids looking on. Has anyone asked what it would take to make the world so great that no one wanted to blow up planes?

Just an idea...

I refuse to bribe thugs to get a partial reprieve from their thuggery.

jeffcpix: Just making more jobs for the Deplorables

I understand his comment to mean that the TSA is essentially a jobs program for uneducated people with a tendency toward authoritarianism and xenophobia, rather than something that provides a substantive contribution toward public safety.

I agree with it, too.

On article Ten things we're hoping for from the Nikon D850 (478 comments in total)
In reply to:

BokehFanatic: Looking at the list and the lists in the comments it's clear that the D810 is still extremely good.

Sure, all those features are very nice, but for 99% of the people it won't affect the output too much.

For sure. Nikon's been making essentially the same camera for a long while, and that's no bad thing; sensors have been at a very high plateau of quality for a while, ergonomics have been pretty well worked out, etc.

The one thing that would be a significant improvement for action photographers would be the D5/D500 autofocus system. I have a D500 and it really is a substantial improvement on the D810/D7100 AF.

Turbguy1: The word "holographic" has been mentioned several times. If this device has a true "holographic" display, then it would produce a full 3D image in space with the display held at any orientation angle, not just exactly portrait, or exactly landscape, but all rotational angles in between. This requires an INCREDIBLE amount of data to be displayed. And that's for a STILL!

I would suspect it would take a "light field display" (similar to a "light field camera") to produce such a viewing device.

We all know the current success of light field cameras...

That said, the finest autostereoscopic device I have seen is the King 7S smartphone. A high resolution lenticular screen.

It would indeed require a light-field display -- a display where the relative phase of light between pixels can be controlled.

That is officially hard.

On article Shooting experience: how the Nikon D7500 won me over (194 comments in total)
In reply to:

ChapelThrill23: Modern SLRs tend to be evolutionary and a lot of people on here hate on them because they are rarely groundbreaking but the fact is that a good modern DSLR is a phenomenally capable camera. Even the entry level ones are capable of producing fantastic images in most situations and can match or exceed much more expensive cameras from just a few years ago.

I have no idea why people hate on the modern DSLR. Yes, Nikon's been selling the same camera with minor changes for a while, but that's because they've had it right for a while. The D7500 sounds basically like my D7100 with a deeper buffer and a few bells and whistles -- and that's no bad thing.

In reply to:

Hibiscusbloom: There is nothing new in technology and they keep churning up DSLRs. Start the road to mirrorless, please. Wake up Canon and Nikon, you are producing dinosaurs!!

Really? The Nikon setup that I use would actually be *larger*, not smaller, on mirrorless to do the same thing. (D7100 + 300/4E + TC1.4)

mikey fried: I have a macbook pro and had to install windows 10 via bootcamp to run some software ( - so basically it works as a windows 10 pc). I've actually come to realise that it is so much faster running as a pc and windows 10 seems so refreshing and innovative compared the the tired old mac updates. Much more powerful pc options out there for considerably less money - so no more macs for me.

I have no idea because I'm not a CAD artist; I'm a physicist. A quick Google says that there is some software available, but it may not meet your criteria for "seriousness"; if you want something else, you'll need to emulate or run another OS.

I've been blown away by the quality of my (two-year-old) XPS 13, especially given its low price. Windows is garbage, but a quick Linux install and it's been a workhorse for my job. The XPS 15's look amazing (and sometimes I wish I'd gotten the bigger machine).

What does the power draw of a processor have to do with the amount of RAM?

Maaggix: A few years too late.

Olympus has a 300/2.8 design they could just take out and dust off, and Sigma makes all kinds of nice glass.

Nuno Souto: Nikon decided to say goodbye to their faithful customers, around 8 years ago.
Any wonder those same customers decided to say goodbye to Nikon?
:)
(I was one of them)

Nikon, as a mature company selling a mature product (DSLR's and lenses), doesn't really need massive R&D spending. They certainly still do it, though... *looks at 300 f/4 lens that's less than six inches long*

Albert Valentino: I was a die hard Nikon shooter but after waiting five years for the D400 I moved on. At a trade show years back I asked were the D400 was and they pointed to the D800 and said this is it, use Dx mode. That 'attitude' was not an isolated incident and i think in came around to bite them in the backside. They rested on their laurels while smaller camera companies planned and took risks. Fuji is a great example of bursting forth on the scene and growing their base.

Overall I do wish them well. I have a soft spot for all lomg time camera companies like Pentax, Olympus, Leica, Canon, Nikon. Less so with electronics companies like Sony and Panasonic (but I am warming to Panasonic, especially their Pana-Leica lenses.

Yeah... that doesn't really make sense. They could have had a much more cooperative venture, starting with an agreement about whether IS should live in the camera or the lens.

It's really a shame that the Olympus/Panasonic alliance in m4/3 hasn't resulted in more marketshare. Their technology is excellent on both sides -- the Panaleica lenses are great, the Zuiko lenses are just as good, and both Olympus and Panasonic have a ton of experience making good cameras.

rev32: Hopefully Nikon will kick it up a notch or two and make gains in market share. I'm happy for Sony, but really want to continue being a Nikon user...

I have the Toshiba-sensored D7100 and, other than banding in some extreme circumstances, it's a fine sensor.

In reply to:

Angrymagpie: I like it but can't see myself ever using 18 frames per second.
The only problem I have with MFT is high ISO noise. MFT is my preferred system, but whenever I know I'd be shooting indoor or at night, it'd have to stay behind.
It'd be very exciting if there's big sensor improvement; I'd be thrilled if we are getting something comparable to the APSC sensor in the a6000.

re: high ISO noise: remember that you in general get faster apertures than the DX crowd. You have f/1.2 or f/1.4 available for a lot of focal lengths, and the very high sharpness of a lot of the glass means you don't need to do as much sharpening (which exacerbates noise).

Olympus has always made fantastic stuff, dating back to my old E-510. They were held back by bad sensors for a while (made by someone else), but now that they've got access to good sensors, anytime a small sensor size is sufficient Olympus m4/3 stuff seems great.
