i have a Minolta Maxxum 7D. I read recently a Q&A by Lepp that you should not have "image stabilization" on while a camera is on a tripod, becuase the camnera tends to look for anti-stabilization, and in effect, if it finds none it creates it's own, thereby maybe messing up the capture. I wonder if this applies to my Minolta 7D, where the term is Anti-Shake feature. should i turn it off when I have the camera on a tripod? has anyone noticed any real difference? thanks
Yes, turn it off on the tripod. IS is designed for handheld use.
Bill - Thanks again..you always have good answers. I did do a "test" just now..i had my minolta take a photo of itself in the mirror, using a remote cable, with stabilization on at first and off in the second. both were in RAW format. oddly, though..when i zoom to 200%, i got a different answer - i could read the small text BETTER with stabilization on. is that a fluke? it was a tad blurier with stabilization off. I'll keep experimenting though..cuase i'd love to get sharper images, espcially when doing macro stuff.
thanks for a quick reply!
Arthur, my apologies. I was thinking of IS in the lens, not in the camera. (I had, by the time I wrote my response, consumed one-half of a small glass of Jack Daniels, you see.) I'm not familiar with Anti-Shake in the 7D, but it sounds like it applies some image sharpening in-camera. If so, it may or may not be a result you want. At 200 percent, do you see any evidence of pixelization on the text edges?
Hopefully, there's a 7D guru lurking who can give you a better answer.....
Bill's answer is exactly correct for my Canon Rebel XT with an IS lens. The IS system looks for movement and if the camera is fixed the IS system itself tends to create a small oscillation which blurs the image. But it doesn't ALWAYS do that. Sometimes it works ok - possibly because there's occasionaly some instability in the tripod positioning.
At any rate, it's a good idea to turn the stabilization off when you use a tripod with my camera. Not sure if it'd be different for your camera.
