comment How to photograph low light indoor sport?
Underexposing to keep ISO lower will eventually result in more noise after post-processing correction than using correct ISO would, see Is it better to shoot with a higher ISO, or use lower ISO and raise the exposure in post-processing?

comment Why is the focus indicator light always on in single point focus mode on my D7000?
@AnedaSmith Yes. With thin depth of field, using focus point closest to subject final framing will generally improve focus accuracy. In certain situations, closest cross-type focus point may have an advantage.

comment What algorithm can I use to simulate bokeh?
Perhaps this would help: What's the difference between Bokeh and Gaussian Blur?

comment Why does my Canon DSLR stop recording video automatically?
My 2 cents: it's on topic because if the problem really is caused by slow SD write, it would likely also affect burst mode shooting limits

comment What exactly is flash sync speed, and should it be a factor in a buying decision?
Note that when action is so fast that faster than sync speed shutter is needed to freeze it, there will be rolling shutter artifacts visible because capture time of edges of the frame is still sync speed apart.

comment What's the difference between CCD and CMOS image sensors?
@smigol That is indeed how fast sync works, but it will be less efficient regarding flash to ambient light ratio.

comment Is analog gain really actually power-of-two only?
I doubt it's nitpicking when shooting JPEG, where the idea might be to avoid need for post-processing as much as possible, and there's much less leeway in dynamic range.

comment Why is there a mechanical shutter in a digital camera?
@ybungalobill Thanks for pointing out, edited to clarify this. It appears the technology is implemented in high-end cameras, but most people just wouldn't consider million-dollar systems (or even $30k systems) a viable option for photography :)

comment Is it safe to zoom while taking a photo for the effect?
What about AF mechanism, can it be left engaged? Simpler lenses don't allow AF override, and zooming affects focus on varifocal lenses. E.g. a Canon zooms manual warns to not touch rotating parts while AF is active, but it's hard to align zooming exactly with shutter.

comment Marathon & Sports Event Photographers: Are they freelance or agency/company-related?
A photographer has quoted the rate of $.17/photo in 2013.

comment Wide angle or ultra-wide (fisheye) lens for interior and exterior architecture shots?
For your listed usage, fish-eye really isn't an option, unless you really like dramatic and fun bent houses.

comment Why is the image size different in portrait and landscape mode?
Is portrait/landscape mode the only difference? If you're using another lens as well, I'd imagine lens correction having a role here.

comment How useful is the top LCD screen on a DSLR?
And there are plenty of models where LCD cannot be tilted even without water protection cover.

comment What are some other terms for a 3/4 shot?
The Wikipedia article has a disclaimer regarding missing references, so it could be just one editor's opinion. There is a historical reason why the term developed in cinematic context, but as a notion of composition I don't see why these terms couldn't be used in photography (especially 3/4).

comment Is there any difference in image stabilization in smartphone camera and DSLR camera?
@dpollitt any references? Apple seems to claim using both digital and optical stabilization for photography on its iPhone 6 camera page: iPhone 6 Plus introduces optical image stabilization that works with the A8 chip, gyroscope, and M8 motion coprocessor to measure motion data and provide precise lens movement to compensate for hand shake in lower light. The fusing together of long- and short-exposure images also helps to reduce subject motion. This unique integration of hardware and software delivers beautiful low-light photos.

comment Is there any difference in image stabilization in smartphone camera and DSLR camera?
Smartphone lenses certainly aren't much wider than those Sony/Canon 10-18mm APS-C zooms, e.g. iPhone lenses have even tighter field of view than the long end of those zooms. Canon does offer wide stabilized primes (24mm, 28mm, 35mm), so perhaps it's not that similar to Nikon regarding the topic here.

comment Is there any difference in image stabilization in smartphone camera and DSLR camera?
Actually the Nikon's lineup does include a 16-35 FX VR wide zoom lens. Canon and Sony provide stabilization on APS-C zooms with wider end at 10mm. Pentax stabilizes any lens that mounts. So the feature is available on DSLRs for even wider focal lengths, and considered useful in situations where subject allows for a longer exposure.

comment How can I compare 'super-zoom' lenses to make up my mind which one I should buy?
I don't think there are any f/2.8 superzoom lenses. If you are going to suggest another category, why would you exclude prime lenses?

comment What is bokeh, exactly?
Does the term refer strictly to quality of background blur, or would foreground blur also qualify?

comment Will any non-AF lens work on a Nikon camera with built in AF already in the camera body?
On a Nikkor lens, letter G indicates that the lens communicates focus distance and does not have an aperture ring. It does not tell anything about presence or absence of internal focusing motor. There are plenty of G lenses with focusing motor and there are also AF lenses without motor and without letter G. Presence of in-lens focusing motor is indicated by letters AF-I or AF-S. And no, not all current lenses have built in motors, some are still relying on body to provide AF motor (e.g. Nikkor AF 16mm f/2.8D) and some even completely manual focus (e.g. Nikkor 50mm f/1.2).
