coldcut: Sometimes I wish that more focus were put on work that are documenting positive things. Sure, the world is a harsh place, but we get bombarded with news every day. There are lot of good things to be found too, and somehow I feel that promoting the good should be rewarded, without forgetting those in need.

matthew saville: I must say, I'm confused as to why she thought she had to time each shot perfectly, with that much firepower. Though I am not a fan of the "spray and pray" method for getting keeper shots, in this particular instance I might have made an exception since there was a limited number of kayakers, and a limited window of time.

It was probably shot at f/2.8 and an extremely high ISO. Even at a great distance, two 600 EX's should be able to push enough light out at 1/128 power (especially zoomed in) to hit at least 10+ FPS for a handful of shots. Or heck, even at 1/64 or 1/32 power you ought to be able to get 2-3 shots off at 10+ FPS.

Yup, I just tested my crappy old Nikon SB80. At 1/128 power it hit 10 FPS for 3+ seconds. (I only stopped because I didn't want to burn my shutter.)

Also, thanks to the awesome Nikon flash interface, I can easily see that even such an old flash (with a lesser GN than a 600 EX RT) can hit ~50 ft when set to f/2.8 and ISO 6400, 105mm flash zoom at 1/128 power.

Apparently she shot the final photo at ISO640, f3.2, 1/250th.

Lan: Fascinating! I wonder what his contemporary setup would be if he were still alive today?

LOL; some great responses guys!

M1963: Surely you'd want to dodge that one ;)

CopCarSS: Now we just need to convince the pixel peepers of DPR to actually go out and take photos (and enjoy the experience) instead of arguing about ISO 51,200 noise comparisons and the dreaded "equivalency" discussions all day long.

CopCarSS: Some pixel peepers clearly enjoy arguing about noise levels and equivalency, otherwise they wouldn't do it... Personally, I enjoy the pixel peeping, but not the endless arguing.

bluevellet: Next, open one of those cameras without visible screws.

That's easy; but putting them back together again is another story ;)

Typo, paragraph 1: <95 CRI, should be >95 CRI.

On article DxO OpticsPro 11 brings advanced Raw noise reduction (110 comments in total)

When I follow the link above, I get taken to the download page, but clicking on the link for Trial/OpticsPro/Win just takes me back to the homepage. I am logged into the DxO site though, so that might be the reason. Anyway this link actually works for me:

Be warned though, the file is 440MB!

On article Waterfails: We test Pentax K-1's Pixel Shift (225 comments in total)

I think this would have been rather more interesting if it had been compared with a different camera as well - say an A7R? They're roughly comparable in price at the moment.

Based on these samples I'd say pixel shift isn't worth the massive increase in file size.

The detail I'd expected to be picked up on here, but hasn't been so far - is the super-resolution feature. There's a 92MP mode. I'm hoping that, since there's an OIS present, they're doing a pixel shift implementation.

Also, although the screen is only 1920x1080, it is Super AMOLED.

Karroly: " Hi-Res Audio (HRA) that provides up to four-times-better sound quality than CDs"
When evaluating audio signals, I know that one can measure distortion, bandwidth, S/N ratio, dynamic range, channel separation. But quality ? Which unit is it ? MBS (Marketing BullS...) ?

I was thinking MBS too, but apparently the key to HRA systems is support of a non-lossy codec like FLAC. Higher sample rates, and higher sample resolutions also feature - the Zenfone 3 supports 192k/24bit.

Either that or they're referring to the obsolete Intel specification from 2004 ;)

In reply to:

SanPedro: They look pretty nice for an 'always with you' camera. Given the processing power that's now in phones, how long before pixel shift technology could be used to improve image quality. Couldn't this be used to effectively increase the size of the sensor?

Most folks are unlikely to use these on a tripod; which is currently required for pixel shift. Also I suspect the size of the pixels might make things tricky too.

Another great new feature only for CC users. Oh wait, no, I created an action to do this already ;)

Executive summary: Centre sharp, but corners soft.

High levels of astigamatism/coma appear to be the reason for the relatively poor showing at the corners; so this is not the lens of choice for astrophotography.

That said the A7R2 is a harsh test for any lens. Based on my experiences on a 5D2, I suspect the Samyang 14mm f2.8 might be a better option, but I haven't tried it on an A7R2...

In reply to:

Esign: Macro 45? Maybe, with the LEDs. Greater depth of field than with 100-200 macro lenses. I'm most concerned about distortion, because this lens could be useful as "scanner" of old drawings and other larger documents which I now have to first borrow (it's hard to persuade an archivist) and then take to the copy shop for scanning, and I have to pay $300 anyway.

Oh, it's you that keeps sending me #!%&$£!$ photographs of documents!

Please buy a scanner, you'll never guess what they're really useful for ;)

I can't believe they didn't include the first digital camera, or the first dSLR, or the most popular digital camera, or...

Instead they included Google Glass, which to date has made no difference to anything, the Fitbit, Nest, and Roku?!

On a photo in the Canon EOS Rebel T6 real-world sample gallery sample gallery (1 comment in total)

I do wish Canon would work on their JPEG detail rendering; the colours are pleasing, but at 100% the levels are detail in the JPEGs are (as usual) well below that shown by the RAW files.

When you're targetting the JPEG market, why not make those JPEGs sing? C'mon Canon, you know you can!

So, take one of the most significant advantages of shooting digital, remove it, and then charge more for the result. Neat!

Leica M-D (Typ 262) owners - if anyone wants one, I can sell you a car - I'll take off the wheels, but since I'm feeling generous I'll only double the price of the car without them ;)

"Lytro specifically mentioned that different versions of Cinema are planned, some smaller in size"

Which vaguely suggests some might be *larger* in size... Well I guess if you found a Ferrari didn't help ;)

On article Miggo wants to 'DSLR your iPhone' with the Pictar grip (135 comments in total)
In reply to:

Simion1: One of the main problems with phones is that they are thin. And because they're thin that means they have tiny sensors, with tiny lenses projecting images onto those tiny sensors. So when I first saw these product pics my first reaction was 'Cool, someone has invented a way to use a bigger sensor with a smartphone'.

But, it turns out all this product does is make the phone bigger? To me it seems like a wasted opportunity where they could have given the phone both more grip and used a bigger sensor/lens at the same time, which really would solve a problem.

It seems like a wasted opportunity to me too; but if you want a better camera for an iPhone, get a DxO One!
