In a book about G12, the author suggests turning off the I.S. when using macro and camera on a tripod. Even if camera is on a tripod, this seems like a step I could skip. Why would it be advisable to turn off I.S. ? Thanks for the help for an old timer.

Supposedly, IS (Image Stabilization) and VR (Vibration Reduction) are "active" programs, seeking to counter minute camera or lens movements. If none are found, such as when attached to a solid tripod, IS or VR can actually induce a bit of internal lens movement.

Canon, Nikon, Sony, Olympus, etc., all recommend disabling stabilization programs when using a tripod.

While it is usually best to deactivate image stabilization when using a tripod, both Nikon and Canon now have certain lenses with a "Tripod Detection" mode which, in Nikon's case (Canon's description is harder to find), helps to reduce the minute vibrations that occur when tripod mounted.

So, it may no longer always be necessary or desirable to deactivate image stabilization when using a tripod with some lenses.

I don't even have to look up the prices of these lenses to know that I will never own one. When the camera is on the tripod, VR is off.

I wonder why every lens maker has to use a different term for the same thing: VR, VC, IS. And why does Canon have to use Av and Tv, instead of A and S? There's a lot to be said for standardization. Look at the costly mistakes that have been made with space telescopes mixing English and metric measurements.

Nikon and Canon only want their own standard. Canon used Av for Aperture Value and Tv for Time Value. Nikon is in a different world than the one I'm in so I don't try to know it. :P

Test it and you'll know for sure.

Tape a newspaper to a wall, move back 10 feet and shoot a page. Do it a few times, on a tripod, is on and is off.

Nikon has simplified the modes for all "A" for Aperture priority and "S" for Shutter priority.
I always turn off VR or OS when on a tripod and select the Mirror-Up option for slower exposures.

I had the exact same thought about these three mentioned lenses. If you have to ask "How much?", then you cannot afford them.

In spite of being a die-hard Nikonian, I think Canon got it closer to right by naming shutter control Tv (Time value), because it is NOT Shutter Speed (distance over time) but Shutter Duration (time alone). And Av (Aperture value) is okay, because it differentiates from a green "A" for (full) Auto.

Just for giggles, I like this (mis-)explanation best:
AV meant audio visual mode - recording sound with video capture.

TV mode sets the shutter to take screen shots of the television, automatically syncing with European 25fps double interlaced and American 30fps double interlaced screen images.

Thanks folks. Now I know. Wilbur

I agree... I perfer standardization over non. The fact is that every lens maker wants the "other guy" to standardize on THEIR stuff. Can we all just get along? ha ha.

The three Nikon lenses mentioned in the article are not the only lenses with tripod detection. They merely have an additional switch that allows the user to manually select the tripod mode.

I have a very affordable Nikkor 55-300mm lens that, I was surprised to discover, includes the tripod detection mode. The feature seems to be somewhat obscure, and not always called out in the advertising specs. You might need to dig a little to find it.

It's called "Patent Infringement". If Company B makes their cameras look too much like Company A's camera, Company A promptly sues Company B. Such as Apple--->Microsoft re: Windows look and feel. Apple conveniently 'forgot' that Jobs got the idea of windows and mice from a visit to Xerox's Palo Alto Research Center. If things look too closely related, the lawyers step in. And that's usually no good for anybody.

So Nikon must have copyrighted the letters A and S. Very clever of them (just kidding).

DSLRs already look so much alike that when you see them on TV shows, they often have the name taped over so you can't see the brand. It takes a knowing observer to tell a Nikon from a Canon on TV. When you can see the brand name, as in the CSI shows, it is because Nikon supplies the equipment and pays them a fee besides. Once I noticed that the CSI:NY show was using the Nikon D3x. I can't imagine NYC spending $8,000 each for a dozen or more cameras. But you never know.

As for patent lawsuits, that has become a standard business practice now. Companies buy thousands of patents and look for someone to sue. Kodak hoped to get some money selling its patents, but it didn't work out.

Remember years ago when car makers decided how their automatic transmission displays would be arranged? GM used one system, Ford used another, etc. We had an Olds, and the arrangement was P N D S L R. Finally, for the sake of safety, they had to standardize.

Well, I guess that's enough for now.

Here's another candidate for the FAQ.
