I don't own a high-end mid-range zoom, so I'll go with primes. Nikon: AF-S 28/1.4E, 58/1.4G, 105/1.4E Sigma: 35/1.4 Art, 85/1.4 Art, 135/1.8 Art Zeiss: Milvus 35/1.4*, Milvus 85/1.4, 135 f/2 Sonnar ...

Does 10fps apply only to DX crop?

For your route planning, be sure to peruse this resource: http://darksitefinder.com/maps/world.html If you want to be able to use longer exposures and still obtain crisp star images, you will need ...

I take measurements and explain what they mean.  This separates fact from opinion. http://actionphotosbymarianne.com/tech/SA4D/start.html https://www.dpreview.com/forums/post/33806693 https://www.d ...

Nikon 1 V3 does 18.4Mpix up to 60fps.  That's 3x faster than 46Mpix at 8fps. If you want AF to be active, the V3 still does 20fps at full resolution, and that was achieved over 3 years ago.

Someone should set up a raffle.  Why doesn't dpReview have that thread feature? We could take guesses on both price, and what the viewfinder feature(s) will actually be.

I never cared to use any camera's rear screen while shooting, for many reasons:  Poor stability, low visibility in high ambient light, small (angular) image size, etc.  It disappointed me, that ...

You're talking about per-pixel noise.  Many users are more concerned about total image noise, which has little dependence on pixel count; quantum efficiency is most important in this respect.  If ...

Giving this a little more thought - For a given light-gathering area, vertical pupils would offer sharper vertical edges in out-of-focus areas, making horizontal movement easier to detect in the ...

No, but 56 would be.  A 56Mpix FX sensor has the same photosite pitch as a 24Mpix DX sensor, so would cover all applications of the DX camera as well. As it is, the D7200 still has its place.  In ...

It is that simple, for point sources of light such as specular reflections and distant lights. And reptiles. But I don't think any of them care at all about their bokeh quality, as long as they can ...

The function of a lens is to map each point on the subject, to a single point in the image.  However, each point on the subject emits light rays to the entire surface of the lens (and the lens ...

Correct.  It means the camera will convert individual 8K-wide images into a video file, as a post-process step, rather than in real time.  Several other Nikon cameras will do this, at lower ...

Knowing that there is an EVF ( if Mr. "Jump-to-conclusions" angry photographer is correct) is a very small piece of the puzzle. The greater questions concern what Nikon would be doing with that ...

Are you serious? Sorry, but your camera is definitely not "working great."  DudleyG is right:  There is a malfunction of the vertical shutter release.  It could be a simple short or mechanical ...

What shape are eyeglass lenses, while they are being molded, ground or polished?  I am fairly sure that cutting to shape for fitting the chosen frame style must be a final step, as there are ...

Not a testing issue.  Focus doesn't matter. Regardless of how this lens is focused, it will not yield a sharp image across the frame.

The check only takes a minute or two.  If adjustment is needed, that will take a little longer, as you will need several checks. My usual shooting situation where I am checking AF, is skaters ...

I think this coating improvement comes rather close to revolutionary (AI 105/2.5 and AI-s 105/2.5): I should also mention that cut-in of SIC coating does not always coincide with changeover from AI ...

How close is your close-up work?  The 105/1.4E isn't what I would consider to be a close-up lens, and it doesn't like extension tubes, if you were considering that approach. What is it about your ...
