A couple of people in the forum have asked me about the anti-shake on the A1, so I thought I would post this. Here <http://members.aol.com/bkbrun/seminole.jpg> is a pic I took a couple of days ago in a very dark museum. Available light, ISO 200, and the exposure time is 4/10 of a second, handheld.

I assume you were shooting with the widest angle that the lens would permit. This is a very impressive demo and it is about one stop more than I would have expected from this camera …. It looks like Minolta has a very good handle on camera shake with this technology. Very nice photograph as well.

Hi Barbara,

And here’s <http://www.softcom.net/users/dsnelson/jubilee/pheasant.jpg> a picture I took with my A1 last week. This was taken with a higher shutter speed than yours (1/100), but the zoom, both optical and digital, was extreme. This guy was quite a ways away, and even at the 7X optical zoom limit, was still quite small in the raw image. Unfortunately I didn’t keep track of how much additional digital "zoom" I added in Photoshop, but it was considerable — at least 3X, I’d guess, maybe more. I just kept magnifying until the pixelation became objectionable.

Nice photo Barb and 4/10 of a second is quiet impressive. It makes me want to look in to getting an image stabilized lens.

Long before image stabilized lenses and not chip I developed my own system of image stability. While it is not free it is cheap. buy a 1/4" x 20 bolt 3/4′ in length is long enough. Now get a length of light chain that the bolt will go through. The length of the chain is determined by the height of the shooter. Put the bolt through the chain and screw it into the camera. Drop the free end of the chain onto the floor. Step on the chain and pull up putting tension on the chain. This arrangement of tension will give you at least 2 f-stops of stability.

Thanks for the tip Grant. Looks like a trip to Home Depot is in order.

Grant, yes. BTW, I have the old ringbolt and chain doodad from my Nikkormat years, but I find that for me it’s not as useful with a digi because it doesn’t work so well when you want to hold the camera in portrait mode. With film that wasn’t such an issue–you could just crop in those situations, but I generally need all the pixels I can get.

Dan, thanks for sharing the pheasant. Did you know that you can get teleconverters for the A1/A2? Minolta just came out with one (and a wide angle) and there are a variety of others that will work, too. Expensive, but maybe worth it if you want to do a lot of wildlife photography.

James, you’re probably already aware of this, but just in case–what’s different about MInolta’s AS is that it’s in the camera body, not the lens. So a lot of people are keeping a very close eye on their new DSLR that’s supposed to be out this fall.

Rumour has it that the new Minolta dSLR will not only have the stabilizing platform but will have an added twist to it. The story I get is that on camera start up the platform will shake violently thus dislodging any dust. The dust will fall to a sticky catch all. In this way Minolta is hoping to lessen the problem of dust on the target that has hounded dSLRs. of course this is all rumour so don’t take it to the bank.

Oh and the chain just lays across the base of the body when I do a vertical and I just have to brace from a slight torque do to the position of the chain, once you are aware of this it is not much of a problem.

Grant, Grant, doesn’t the Oly E1 already do the ccd shake? I thought I saw that in a review. Maybe I’m mistaken.

Oh … it maybe let me check. Fingers shuffling off to an E1 site … …. fingers shuffling back. You’re not mistake! So if Minolta dose this they will not be the first. See you learn something new every day.

Thanks a lot Barbara…you’ve probably forced me to raid the piggy bank again! 🙂

But not for a while. I need to learn how to use the built-in features of this camera before I start looking at add-ons.
