i gave up after one took more than 10 minutes.

In reply to:

mxx: For those who wondered why people use 28 mm lenses:

"According to Marinkovic, he favors 28mm because it offers a wide field of view without being unnatural - allowing him 'to fit things into a frame without overflowing it or distorting the corner elements'. "

@HP1999 28mm takes in about 56% more image area at a given distance than 35mm. It's a pretty significant difference. 24mm more than double the image area of 35mm.

Dante Birchen: Pics look cooked. The guy is a Nikon Ambassador. So of course he is positive about the lens. I think I would prefer 35mm for most of these shots. We won't know the true quality of this lens until people start posting their cat pics and garden flowers.

With the D820. Can't tell anything with such a low resolution camera. Of course, you'll probably have to use f/2 or even f/2.8 with the 820to get enough DOF to get the entire eyelash in focus.

Based on Nikon's MTF curves, they've substantially improved since the 24 and 35 f/1.4s in minimizing astigmatism and upping across-the-field resolution. Looks like a winner to me.

Now if they would just take on the 50 one more time, they could have a winner there as well.

Looks like landscape mode to me.

avicenanw: Nikon did some serious twists and contortions to come up with this model by skipping the D7300 and D7400

ditto D400. This is the Nikon generation 5.

SmilerGrogan: Impossible to choose: The D500 finally, finally! has reasonable focus point coverage across the frame, while the D7500 offers the essential-for-me magical Nikon CLS. Can't afford both, may have to just drown myself in the Chattahoochee

CLS works fine on the D500, you just need a commander. I use the SU800, but one of the Nikon flashes with commander mode will also work. If you have or are going to the radio-controlled flash system, the D500 will be compatible with the remote adapter which also frees up your flash from the camera.

One month of data does not a year make, but Nikon does need to get on the ball.

Jacques Cornell: "Image quality compared to full frame"???
What, are the Fuji images cropped? They're not full frame? Does language mean anything any more?
You guys have drunk the marketing Kool-Aid: 35mm is not "full frame". Any image that's not cropped AFTER capture is "full frame". Duh.
The section should be titled "Image quality compared to 35mm." Sheesh.

I know what it means. Most other people on DPR know what it means. It means what it's meant since Olympus popularized the term "half frame" with the Pen cameras, and 24 x 36 thereafter became widely known and referred to as full frame. While the Pen cameras were first termed "single frame," that didn't last, and "half frame" stuck. No reason to stop using that term now - it's still a useful reference point for sensor sizes, crop factors, etc.

Now if you really want to attack a term that's confusing and misleading, why not take on "1-inch" sensors?

xmeda: I like my Sig 100-300/4

100-400/5-6.3 is not worth existence. 60-300/4-5.6 FF lens would be more interesting both for APS-C and FF users.

At 1/3 stop slower, f/6.3 isn't a huge compromise with f/5.6 lenses provided the camera can AF at f/6.3. The size/weight advantages over an 80-400 f/5.6 are pretty significant here - I can see why someone would pick this if the image quality is good and the AF works well. Based on Sigma rep for C lenses, S version might be much better for AF if they bring one out, should still be more compact and less expensive than OEM 80-400s.

DoubleDash: Available right after my holiday....:(

Love the price, thought it would be more expensive. But problably still >900euro's. EU is to expensive

@Impulses - Most states with sales/use tax require payment of tax on Internet sales if the vendor doesn't charge it. That's one reason it's so much trouble to buy from B&H - I have to keep track of everything myself so I can pay the sales tax at the end of the year. Some people I'm sure evade the sales tax on internet sales, but it's still a legal requirement.

Paul B Jones: Easy. 800mm. I photograph wildlife. Reach is the main issue for me in the vast majority of photo situations. 800mm is the most reachy focal length. Therefore, 800mm.

I can accept that others might have a different choice, and that is okay.

And if you need a wide shot, you can just do a panorama and stitch in software. A very detailed panorama. So the 800 really is the do-everything lens.

Anything less than 256 gb and don't you need at least a half dozen for anything useful, like a day's work? How big are those Hasselblad 16-bit images anyway? It's like a roll of film, vs rolling your own.

Peak freak: The hitchhiking octopus for me. I haven't seen anything like it before (especially, the F.O.V) which immediately separates it from the others.
Number 12 (the steps) stands as an odd one out. While I can see the appeal, the actual content holds no tangible interest, which is important to me.

Light and shadow, yielding shape, pattern, repetition, texture, movement, composition - those are the "content" in 12. Things that attract the eye and light up the brain and evoke my response to this image. It's a level of abstraction from the physical things in the photograph.

In reply to:

mikeodial: Can a new strap on an existing Nikon camera be news? I feel sorry for the journalists there trying to find a story amongst the "no new products". Perhaps a message for this segment of the industry.

It's not the strap that's news - it's the first line - "[No] new products." Of course, the strap contradicts that. The only quesion is, will the new product be for sale? And if not, is it really a new product? The photo does make the point, and quite nicely, thank you.

The 19 PC-E Nikkor should complement Fujifilm's lens range nicely - Perhaps Novoflex will do an adapter that controls the aperture.

On article Nikon PC Nikkor 19mm F4E sample gallery (87 comments in total)

I am on the road and have not been able to quantitatively test the lens, but am extremely impressed by what I see in the finder and the results at 100% with the D810. I use these lenses on architecture and interiors, small urban spaces, mostly shift rather than tilt. This lens shows very good resolution across the frame, good contrast, little problem with flare or ghosting if sources are blocked with my hand. Distortion seems very low compared to other wide Nikkors including my old 28 PC. Seems very sturdy and operates beautifully. Nicely executed, Nikon.
Could use a hood, frame for attaching small flags, or matte box, even if it only provided protection for unshifted use. Will need to cobble something together.
Does have an unusual very broad but faint CA obvious around dark objects like tree trunks or columns against sky or white background. Color disappears without obvious artifacts with ACR generic correction.

Wildbegonia: This is so amazing. Congratulations for an original project that shows the principle behind the pinhole camera. And it has an extra twist of ingenuity, its potential for recycling waste materials.

Wildbegonia, don't be so fast to yield - you are correct. It is exactly like 30,000 parallel pinhole cameras, with the imaging area the same size as the (relatively large) pinhole behind each pinhole. There is still a conical imaging area before each pinhole - it gets wider as you get farther from the camera. Let's say it is f/127 - 7-inch drinking straws with an aperture of 0.055 inches. The image plane for each straw is a circle 0.055 inches in diameter at the aperture, and grows larger by 0.55+0.55 each 7 inches from the aperture. That is, the outside ray comes from one side of the straw to the other over the length of the straw. At 7 in from the aperture, the outside rays horiz come from a circle 0.055 (diameter of the straw) + 0.055 (the ray from left edge of aperture to right edge of straw at image plane) +0.055 (the ray from right edge of straw at aperture to left edge of straw at image plane), or 0.165 in in diam. It gains diam at 0.11 in per 7 in.
Look through a straw.
