Comment about IS CCD

[munfai]

Not sure if this has been brought up before...

While the anti-shake CCD is a welcome sign that Minolta is waking from it's slumber, I personally feel that the technology developed will be cripled in many ways by its practicality.

For one thing, it's only applicable for digital cameras (DSLR or otherwise). Is it possible for a similar technology to be developed for film-based SLRs? It's not likely that Minolta will be dropping all of their current film SLR line-up, so it will be a huge shame if there is no anti-shake for film users.

Another point is that by putting the anti-shake mechanism on the body itself, it becomes a single point of failure. Assuming that Minolta decides to put this technology in a (D)SLR, and for some reason the mechanism fails when out in the field. So instead of just removing the lens and using another, the user is stuck left with no usable camera body.

Just my 2 cents...

Its much cheaper for the user to have a body with IS than to buy a whole range of IS lenses.

PS: Any chance you'll be coming back to the Minolta camp when the IS body is released ?

it's cheaper, but more headache if something goes wrong.

going back to Minolta? I wouldn't rule out the possiblity... especially if they produce a superb DSLR, and a few new lenses to boot...

Hi Munfai,

I dont see why this technology is not aplicable for film.
This thechnology fronm the first pass info available...seem to use a mechanical compensation and not the digital compensation like most viewcams are using.

The CCD is mounted on a "suspended" platfom which has ective X/Y motion compensators.

As for the failure of parts,......the probability would probably be as equivalent to any camera with motor drives (e.g for AF, flash head zooms etc) currenty on camara bodies.

So in a nutshell, it simply goes to say that if you are a "PRO" or amatuer covering critical events - that can't get away with " ...well its okay...i'll come back another day to take the photo" kinda shoots - then a spare body will always be the essential.

Lets wait and see....

reagards,

It's not appropriate for film because film comes in a continuous roll.
You cannot shift it up and down like the suspended CCD used in the A1, as it would cause warping.

i wouldn't say that it's not impossible for it to be implemented for film. just that for film, then entire film chamber will need to be on the 'suspended' platform. and since the 'platform' in this case is not as small as a CCD/CMOS, power requirements might be higher, as well as resulting in a larger camera body (unless Minolta are miniaturization experts).

then they will also have to contend with the fact that film is not always 100% flat, so there might be added complexity in compensating for this.

The design is for film, I wonder if the CCD version is based on this one.

interesting... but the 'film' here can mean any form of image capture device, be it digital or otherwise.

Hmm.. from what I've read so far, its about film camera based IS. Visit the patent office site, more diagrams can be found there.
