What is the fasination with in body IS ?

costs less to stablise one body than to duplicate it in every lens

doesnt matter what is moving, the same result is achieved

moving the sensor is no riskier than moving the lens elements
and probably a lot easier since it is smaller and lighter

and no nothing stops during hte exposure else you would get
a fuzzy smeared unsharp image (amount depending on the motion )

the is whether body or lens keeps the right light ray hitting the
right sensor cell not be smeared over several of them.

I understand that point but are people not worried about the fact
that the light is being projected onto a moving subject ?

Maybe I do not know enough about the technology but does the sensor
stop moving during the exposure, if it does not then surely this
will create a problem.

At least with the Canon IS the light is arriving at a fixed point...

Ofc MY opinion is based on assumptions, though I find it pretty
self explaing that, if I have a moving sensor inside my EF mount
camera, I get a problem with the circle of reproduction of the
lens, when using a FF sensor.

1) the image circle is always slightly bigger than full frame -- it doesn't stop abruptly at the corners
2) the AS system typically moves the sensor one mm or MUCH less

3) even if 1 and 2 were false, we don't know if Minolta may ever offer a FF camera, and personally I'm not sure I want one

4) even if they offered one and 1 and 2 were false, you could just shave off the edges in-camera to get a usable image (with slightly less coverage)

5) even if they didn't do this amazingly easy thing in-camera, you could always do it yourself in PS, or even automated (look at EXIF tag, if AS on, shave off the edges). Easy batch processing with tools available today

Can we put this age-old non-issue behind us?

No, I don't ... that's why I was asking how this thing works. After you correctly assumed my ignorance, I'd love to be enlighted.

However, I mentioned already somewhere else that IKEA is testing the hardware their furniture for 150,000 actuations, and their stuff still breaks after 2 years.

I am just a bit scared from all them gizmos you have nowadays in the cameras. My Nikon FM2 was a bit cheaper than my Nikon CP5700, and my Mamyia RB was a bit (a very bit!) more expensive. But both cameras I know how to fix and maintain ... these camera will keep a lifetime (my niece is shooting with with 30 year old Mamyia from my father, and a 20 year old one from me. Both cameras work without failure). Of the CP I'm not so sure .... neither of any DSLR .... that's why I'm still holding back.

Yes, but their shoddy stuff is only tested in exactly one way (open - close, open - close, repeat forever) while in daily use there are many ways to harm their shoddy stuff. The AS mechanism, on the other hand, is protected inside the camera and will always work in the same way. Sure, no one can know exactly how the mechanism will work in ten years -- materials age -- but that is true for everything in this world, including photographic stuff from other manufacturers.

I think the right way to treat modern DSLR cameras is as "disposable". Meaning, don't buy anything that you can't replace in three years. I have already learnt the hard way that a short drop that wouldn't affect my film cameras may kill a DSLR dead.

Having the IS within each individual lens allows canon to adjust
the IS system specifically for the optics for that lens, thus
allowing for a better overall IS system.

Oi, this is the digital age. No rods, cables or sprockets are needed to make AS function. See what DXO does to camera/lens combinations. Don't you think AS can be optimised in the same way?

Maybe the 150,000 actuations before you buy them is what makes them break after you've had them for two years.

Yes, I'm being stupid, but you're comparing cheap furniture to expensive cameras, which evens it out. Compare with cars instead. Lots of electronics and electric wires these days, as compared to the good old days.

When you talk about the cost of a camera, don't forget the price of any film you have used during its lifetime. Maintenance? Again, compare to cars. Change lens/change tyres, change CCD/change electronics. The first thing you do yourself, the other you leave to professionals, or you buy a new.

Am I the only person who does not think that this is a good idea,
in fact it scares me in someways. In no way would we want a frame
of film to be moving in the body to help capture a sharper image,
so why allow the image sensor to move.

I don't know for sure if the data transfer out of the moving part
is done wirelessly or with a wire, but if a wire is used I'd worry about
how long the wire(s) last.

I'd also like to use larger than APS sized sensors later so IS
lenses would still be on my list.

No problem. Cables used in hard disk drives never fail. They work much, much more than the AS system.

There is no problem with larger than APS sensors. Look at other posts in this thread.

I would like to have the final word on this as the first...

Thanks to all ofyou for your valuable insight and opinions on this matter.

And I agree that end of the day neither seems is right or wrong it is down to the user preference.

Good Luck, Happy Shooting and Thanks for your time.
