comment Are fully automatic DSLR lens changers available? What are suitable alternatives?
@BartArondson - Thanks. Yes - that's the basic concept. I don't think most people who decry the "fully automatic" concept have seen what modern automation systems can do, or how compact and powerful an electric drive system can be. Some say they wouldn't sell. I wonder what price they'd need to be to make them saleable. Half the price of a top end body or the price of a good pro lens would get people thinking, I suspect. 1 to 2 second lens changes? Oh yes :-) !

comment Why can't I save video file from canon dslr to computer hard drive?
@Mike - alas even FAT32 has a 4GB limit and all it takes is a somewhat careless programmer and you have a 2GB limit.

comment Why is my SD card filling up too fast?
Most likely "hidden" files as others note BUT there are many fake and clone cards available and you may have one of those - with these anything (bad) can happen.

comment What can be used to “fight” light pollution in astrophotography?
Getting rid of the light is the main fix. A slingshot may work in isolated cases :-). In areas of moderate light pollution where a significant proportion of the effect is caused by light incident on the camera or area immediate to the camera, local shields MAY help. This could start at a matte black painted box or similar around the camera. For the serious, light shielding of a site may be possible (tress or whatever) or good siting. BUT once the light is "in the air" at altitude so that you get a uniform downward "glow", going somewhere better is about the only cure.

comment For the same number of shots, does continuous shooting wear out a shutter or other mechanical parts faster than single shots?
@StanRogers - I'd agree with Stan - but also suggest that the opposite effect MIGHT occur. It would be possible to design a mechanism that it cycled smoothly and transferred energy (say with a buffer block or spring or rotary mass etc) into the mechanical moving parts for the new cycle. Also, some shutter modes in some cameras do not operate a mechanical shutter between exposures in highest speed mode. (The now venerable Minolta 7Hi (not an SLR) has a mechanical shutter whivh was used in all but highest speed burst mode). And some systems (very unnerving) maintain mirror up on fastest burst.

comment How can I make phase-detection AF more accurate with a Canon 650d and 50mm/1.8?
I assume that you are receiving a "focus confirmation" signal in each case, and that these images are the result after you receive it. ?

@mattdm - Did your "it is" mean "it isn't" or did "it is" mean "it is" ? :-)

comment Why is my camera showing a lot of stuck red and white pixels?
@mattdm - I can just reenter the answer details under the other question but that doesn't "move" it per se. Is there a formal means of moving it? Points from upvotes are not especially important wrt their affect on my reputation BUT the upvote count against the answer is an indication of the value that others thought the answer has, and I do value that.

Read the references. Look at the large amounts that Gargoyle says on the topic and then ask further if desired.
