Entropius

Thanks! That's more than I had by far. I had AF off and my lens doesn't have VR, so I'm not sure where the battery went.

Two nights ago I camped by a swamp in the Upper Peninsula of Michigan. I wanted to do an astrophotography series overnight while hiding in my tent from the mosquitoes, so I set the camera on a ...

Something SnapBridge is actually good for :)

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

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...

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...

This sort of thing can happen if there is debris caught in the optical path to the AF sensor, or on top of it. I've not examined my D500 all that carefully on the inside, but I had this problem ...

The D500 is a pretty awesome body. The AF is magic, the build quality is nice, etc. If you care about these things, then those are definitely points in its favor. It won't do wonders in low light ...

I know you like the convenience of using a superzoom lens, but there really is no substitute for aperture when shooting in low light. The D750 might be one stop better than your D5200 at high ISO; ...

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.

No, it's certainly not. I've seen it on superzooms, not-micro Four Thirds cameras with a cheapie 70-300, and several different Nikon and Canon lenses and cameras. It's an optical effect happening ...

This isn't moire. Moire happens because of the ambiguity between high-frequency luminance detail close to the Nyquist cutoff and low-frequency chroma information. You only get ultra-high-frequency ...

This is what I suspect as well. Refraction of light through air can cause all sorts of weirdness, and I've seen this effect -- unexpected structure in bokeh -- quite a bit in Arizona. This is much ...

I don't know how wide you need, how fast you need, or how cheap you need, or whether you need VR, but the Sigma 18-35/1.8 is very good. (no VR, and it's around $700).

Completely agree. There are the Sigma 18-35/1.8 and 50-100/1.8, but those are larger and more expensive than necessary if you don't need a zoom.

Are you talking about focus speed in low light?

* DX: Inexpensive, moderately-fast primes wider than 35mm (competing with the Sigma 18-35/1.8 by being cheaper/smaller) * DX: primes shorter than 18mm, f/2.8 and ideally f/2 or better * More PF ...

I've not used the 200-500, so I can't comment on a comparison. But the AF speed is fine; any misfocused bird-in-flight shots are my own fault generally. It seems perhaps a very slight amount ...

My experience with the 300/4 PF and converter is that image quality is never an issue. While there might be some measurable optical difference between the 300PF + converter and other options, I've ...
