Welcome to the wonderful world of macro product photography.
First, you need to understand that when you photograph things at high magnification, you won't get a whole lot of depth of field. In this instance, very little is in focus. Look at the leftmost two pendant rings at the bottom of the earring on the right: just that little bit is sharp, and most of ...

Very briefly, in a typical SLR camera with lens, the noisemaking parts are:
AF motor
diaphragm (aperture) control,
movable mirror (quiet mode may delay and/or slow the return of the mirror)
mechanical shutter--both release and cock (quiet mode sometimes
separates these and may slow the latter)
optical stabilization (gyroscopes and ...

The command-line utility dcraw can do this, using the dcraw -e flag. However, it apparently has issues with large images in Windows Vista and Windows 7 (see the FAQ on that page).
IrfanView displays the embedded JPEG when opening some forms of RAW. If it's able to open your type, you can simply open the RAW and do a "Save as --> JPEG".

In terms of build quality, I didn't find much of a difference between the 16-85 and the 18-105. I believe the mount material (metal vs. plastic) is overrated as long as you are using consumer bodies which are so frail that you need to take great care of the package anyway.
On a sturdy pro body, the plastic mount might be the weak link indeed, but again ...

Short answer: the difference is in an SLR the mirror flips up to take a photo, whereas the SLT employs a semi-transparent mirror so that the mirror never has to move.
Now to your questions:
1) How does a DSLR do continuous focusing (AI servo/AFC)? Does it literally flip the mirror up, take the shot, put the mirror down, refocuses and repeat?
That's ...

The technology in theory is similar, but the implementation isn't exactly the same.
Without knowing exactly which model, or even which manufacturer made your camera, it is difficult to be very specific. There's a large difference in performance between different models and lenses.
It always starts with light, so let's begin there. The amount of light used ...

I'm not fully sure why you think you need to go as far as a D800, whilst it is an incredible camera (I have one) I see it as overkill for what you are looking at doing.
The D800 is no more complex in general use than most other DSLR's, however it has a lot of advanced features that you will likely never see/use/need.
Nearly any new dslr is capable of full ...

The vast majority of the sound comes from the mirror movement. The shutter is generally the second loudest by a significant margin.
Aperture adjustment, image stabilization and focusing are going to depend on the lens, but they are virtually silent on a good modern lens. You can hear them if you are operating the camera in a quiet environment but ...

Your understanding is accurate. There are variations but the most significant difference is what you see in the viewfinder. This answer goes into all the details.
The other significant difference is that the PDAF sensors are available during exposure and video-capture. This lets an SLT camera measure AF while an image is being recorded and then it adjusts ...

Use DCRaw:
$ dcraw -e MyFile.NEF
You will get a MyFile.thumb.jpg. It should work just the same with Canon files.

There are variations in Canon DSLR.
I had Canon-XT and used non-EMF chipped adapter with very accurate exposure in AV mode. I just turn to the desired aperture setting, get AF confirmed, and take the picture.
For 5D, the story is a little different for the camera's brain is different from the lower level DSLR. I used EMF chipped adapter, and need to adjust ...

There are plenty of similar questions that demand highly and restrict things with a completely unrealistic budget. No wedding photographer would show up with a lens worth under $1000, nor with a single lens or a single camera. Getting a semi-acceptable wildlife lens is also not possible for much less than your entire budget.
There is good news and bad ...

Traditional phase detect autofocus system runs mainly in an open loop configuration: take measurement, send focus distance to lens. Contrast detect autofocus is closed loop, it has to take a contrast measurement, move the lens, take a contrast measurement, move lens etc. which is clearly much slower.
The reason phase detect on sensor isn't nearly as fast as ...

I would like to add that unlike a traditional DSLR, the mirror in an SLT is not essentual to the operation of the camera. It can be removed in a few seconds and carefully stored in many small compact flash card cases. The camera will operate without a complaint in manual mode. The contrast based manual focus assist will still function. The preview in ...

You covered most of the advantages that SLT cameras enjoy over DSLRs, but there are a few other differences that give the traditional DSLR an advantage as well.
With an SLT camera, 100% of the light entering the light box never reaches the sensor. In brighter conditions this loss is fairly minimal, but in very low light conditions it can mean the ...

Most likely the camera is failing to achieve focus (since it doesn't have anything with contrast to determine if it is in focus or not). Some cameras will either not take a photo when they can't achieve a focus lock or have a setting that will tell them not to take a photo when focus lock can not be achieved.
It sounds like your camera either behaves this ...

Mirrorless as of the arrival of the Nikon 1 system, the V2 model can now out-perform top Nikon or canon "full frame" DSLRs in terms of:
in C-AF mode can shoot 15 frames per second individually focused in RAW files for 40 shot buffer depth.
can shoot at 30 or 60 fps in RAW file with focus & exposure locked at first frame, with 40 shot buffer.
This ...

So, I recently bought a used camera. To decide which to buy, I developed this technique:
Make a list of all features that are important to you.
Assign a point value from 1-10 to each feature. Give a 10 to something essential, a 1 to something that barely matters.
Write down the stat for the feature for all of the cameras that you are interested in.
Give ...
