i am proud of being black country even if many of us are bad at english,as my parents were brought up honest, and passed on same values.
i could never be branded a snob,but i,ve been called a racist,because i admitted i had moved to sandwich,kent, 8 years ago to get my children a education in a mainly white grammar school,as opposed(or apposed,i think either word can be used in this context,but its this kind of example that made me hate english at about the age of seven and being stuborn ,i was never the english teachers pet,lol) to sending them to the 70% black secondry school i went to.
i dont think its a crime to make choices for your kids future ,and being honest about why a schools performance has fallen to new lows.
Skip to the present ,kids are doing well,non whites in thier school are doing equally well and if you met them blindfold would not know thier colour,they have no attitude that is noticable.
which only goes to show its not a colour problem as much as a community issue.But moving to sandwich has not turned any of my family into snob,s thank god.
And on that note snobbery is judging people,and its gods job to judge, as i was taught at school.i see snobbery as two of the deadly sins combined.pride and vanity.

You can also get the firmware version from the EXIF as well, so if you buy secondhand you can ask for a recent photo and it will tell you everything, even the manufacture date.
My K10D for example is manufactured in 04-08-2007 and with the last photo was running firmware 1.31.00.19, hasn't being serviced, battery was 56% full, over exposed my shot in manual mode with +1, had 20658 actuations, SR was not stabilized , focal length of 16,3mm, focused very close and you can even read the light values off all the metering segments and more things... very scary

I doubt Sigma has such a SR system since both SR systems should work together if not they will both try to reduce the same movement by the same amount over compensating the reduction.
For the shutter, what about a Kerr cell shutter? link
never mind 50% light loss

Hold down the menu button and poweron the camera it will show you the firmware version.
For shutter actions you can find that in the EXIF data and any advance EXIF viewer should be able to show that information. Most popular here is www.photome.de and that one is free.

With in lens you can actually see the SR working as the image settles down in the viewfinder.
But in body SR can also counteract tilt like in the K7, something in lens SR can never do.Not the only advantage.

But have their advantages, maybe a combination would be the best option.

As the lens SR will still be active as the shutter is pressed.....
Yes the body SR is still running, but it's in the body and maybe it cannot counter the shutter vibration and mirror slap, whereas the lens SR is independent (sort of) of this.
The mirror slap happens before exposure so does not add to the blur at all or stress to the SR system.As the lens SR will still be active as the shutter is pressed.....

Also the lens is firmly connected to the body so any movement the body has will also finds his way to the lens.
I actually think inbody SR has more potential in reducing this effect because they might be able program the sensor to move at the precise time to counter act the shutter movement.
Something lens based SR can not do because that means you need to program the lens for every body out there

Have read that Pentax has updated the SDM motors in the DA*16-50 and the DA*50-135 lenses so there should be less problems with the current generation.Not what I wanted to hear - I have just about made up my mind to go for a DA*16-50mm after using a DA*50-135mm and DA*300mm without any problems for a while.

I think the mirror system is more damped but have read reports of the K7 shutter causing more recoil and therefore more blurred photos than the K20D did.
I believe this was the article that mentioned it http://falklumo.blogspot.com/2010/07/lumolabs-shutter-induced-blur-with-slr.html
points 3 and 4 are of interests.
