Phenomenal photos, as always, and a very inspiring story.

Quick feedback on the layout of these types of articles, though...it took me several moments to determine where to find where the photos were taken, and clicking through each photo to see higher resolutions is a pain.

It would be nice if there was a quick way to see high resolution photos + location info / captions in a slideshow view so I can enjoy the pictures fully and read more of the detailed commentary later, if I choose.

Cheers.

On Behind the Shot: Spot the Shark article (67 comments in total)

Great shot.

I must say, though, many of the "composition analyses" I see like this one feel a bit contrived after-the-fact. I bet most of this particular photographer's skill comes from a strong intuition developed over years of experience about what makes a good picture, rather than an extended study of annotated images like the one presented above.

ajamess: @ DPR - you spec list is incorrect. You should update the spec list to include that we finally get more than 1EV bracketing :).

"2 to 9 frames in steps of 1/3, 1/2, 2/3 or 1 EV; 2 to 5 frames in steps of 2 or 3 EV"

you -> your, whoops.

stevez: A 36MP camera is all about image quality, so I'm happy to see that Nikon has addressed the shock problem with mirror box improvements and an optional electronic first curtain. Wondering if the electronic first curtain mode will slow down the 5 FPS ? I am a little disappointed with the bracketing only offering a maximum of 1EV separation.

Bracketing now goes to 2 and 3 EV. DPR's spec list is wrong.

On Nikon Df real-world samples gallery article (224 comments in total)

So, I went to Glazer's in Seattle and handled one of these fellas. It felt good in the hands, although I'm used to a gripped body (D800 / D7100), so maybe a bit small for my tastes.

One thing I noticed, though, was that the viewfinder was AMAZING. I mean, better than the D800E by a good margin. I don't know what they changed but it was SO easy to manually focus, even with the 50/1.8G SE on it.

I'm excited. F- all the haters. Just thinking about this camera made me pick up my Mamiya 645 again and shoot a roll of 120, and that makes me smile.

Will Lightroom go this same route? I will be extremely depressed if that happens. I have 7 years of investment in that software :(.

In reply to:

Krich13: Well, let me guess... A full-frame 25-50 f/2.8 lens with a built-in Metabones-style telecompressor (aka speed booster)?
I know, the Metabones design only works without a mirror box. They seem to have modified this idea to accomodate a short mirror of an APS-C. These three rer elements do look suspiciously like a focusing group behind the main lens.

MTF looks great (again, just like the speed booster), and that again could be the effect of compression. BTW, at what spatial frequencies is it measured? For cropped sensor (x1.5) I would expect 15 and 45 cycles/mm. If 10/30 cycles/mm is used -- that's cheating.

This was my thought, too (see my comment below). I see no other way of accomplishing such an optical design without it being prohibitively expensive / bulky.

ajamess: This lens looks like it uses the same "trick" the Metabones Speedbooster uses, e.g. compress a full frame image circle down to ASP-C size.

Definitely great marketing, and a great application of clever optics, but it is not "truly" an f/1.8 lens, in the purest sense of the word (it would be much more expensive and a decent amount larger if it were).

MTF looks pretty impressive, so no matter how they came about it, I think it's a pretty big win for the crop shooters out there.

Why are you attacking me? I was merely attempting to explain the likely technology behind this achievement. This lens would have to be much bigger / heavier if the aperture was a true f/1.8 for that zoom range.

The reason this is the case is because in order to get wide FOV's (<20mm or so), the optics have to use what's called a retrofocus design, making it much more difficult to achieve large apertures.

Jeeze. A guy can't even post interesting commentary on optical design any more without getting yelled at.

cleverinstigator: I'm sorry why not put up a few satellite relays in between so we can get some decent images of the planet why spend that much money on a mission that is 8 years behind in sensor technology. 2mp is a joke for landscape shots.

Are you daft?

Take a read about the history of cameras in space before you make a fool of yourself again, then maybe you'll realize how big of a deal it is that they are actually including as good a camera as they did:

Just because this is a camera forum doesn't mean you need to belittle actual scientists' work just because they aren't throwing a D800 on board.

astralux: For me the news in the post is not the subject but the words "while working towards our reviews". The Nikons as wel as the new Canon has been extensively tested elsewhere and users here have written so much about the models that any test now from DPR will just be too little too late and old news. Come on guys, it only takes 2 to 3 days to do the test if you knuckle down. The D4, D800 and 5D Mk III has been the biggest news on the new body front in the last month or so. All we get from DPR is previews and tests on less important models and fiddling with the web site software. Get on with it!

Do you have any idea how long it takes to do the analysis DPR does behind these reviews? I didn't think so. Go outside and take some pictures or something.

Man, you guys sure like to complain about new products. "Oh man, Chevy released a new car! It doesn't have an in-built coffee grinder? What were they thinking?!"

I will never buy one of these, but it's cool that it exists for those who need one. It's okay to be excited about new technology, folks, even if it's from a company that you don't personally prefer.

On Canon announces EOS 5D Mark III 22MP full-frame DSLR article (488 comments in total)

New camera announcements certainly bring out the best in the photography community, don't they? :)

For those of you who can handle a bit of satire, I tried to capture some of the funniest comments from this, and other, threads:

Cheers, and I wish all of you (Canon, Nikon, Sony, or whatever) the best of times with your new cams. It's an exciting time to be a photographer, no doubt!
