In this thread the question was asked is IS/VR really useful or is it more or less awaste of time and money. I was at work today bored as usual so I decided to see for myself how much difference there was in hand held with and without IS. Here are the photos. You decide if it is beneficial or not. These were shot at 420mm F5.6 with a shutter speed of 1/5 second.

No IS

well the results seem to contradict each other so based on that test it seem hit or miss.

Glad you pointed that out because I labeled the first 2 backwards. Sorry

Why not show a tripod shot too?

Unless someone kicks it or there is an earth quake, what's the point? You know it don't move.

I don't want to sound negative, honestly I'm starting to see some value in IS for certain situations.

Are these really real world situations though? Are you really going to come across a situation where you need to be shooting this kind of stuff at 420mm hand held?

And the manufacturers recommend that you turn IS off when it's on a tripod. So IS and tripods aren't even designed to go together. And as dicussed before, tripods aren't always an option.

But it would give you a comparison.

"I'm starting to see some value in IS for certain situations" I would agree to that and I'm the anti IS guy. As long as you know when to use it and go up on ISO instead of using IS if you can. Never use it if you have plenty of light.

I suppose so. But why would you want to incorporate noise into the photo by jumping up the ISO if you didn't have to? I don't use the IS on my lenses when mounted on a tripod or I'm using shutter speeds equal to or faster than the focal length.

I believe you are better off with a noisy sharp picture than a soft picture.

Never use IS on a tripod. My point was you could show these other shots compared to a perfectly still camera shot.

Depends on which lens you have. Third generation Canon IS doesn't need to be turned off when on a tripod.

Which ones are 3rd generation? The 300mm F4 L IS I just bought says to turn it off when used on a tripod. And if I'm not mistaken so does my 24-105 IS

Yes. Today I was shooting eagles that were shaded by a cliff side. My 300mm coupled with a 1.4x extender wouldn't get me a fast enough shutter speed to hand hold in my opinion without bumping the ISO up. So I used mode 2. Alot of the new lenses come with 2 IS modes on them. Mode 2 option stabilizes images while panning with a moving subject.

From Canons website: Stabilizer Mode 2 which steadies the image during horizontal or vertical panning. Mode 2 detects the panning direction automatically.

Try this tomorrow, On a tripod with both shots take one shot at 300mm then add the 1.4 converter. Crop the 300mm shot to make the subject the same size as the one w/converter and compare.

What's that gonna show? That the converter softens the image a little? Everybody knows this already. With or without a converter has nothing to do with hand held camera shake at 1/5 second.

Why is IS with a tripod bad? I figured the only downside would be battery life.

The older versions of IS detect the motion that they create internally as camera shake and try to correct it, then they try to correct the correction, then they try to correct the correction to the correction, then...

Simply, it confuses them.

This makes me want an IS so badly. I have a family member who's an employee at Canon. I had a chance to get the 28-135 for only $300, and I missed out due to finances. (Christmas special)

So sad.

I have IS lenses and love them. IS helps when:

the wind is blowing and your telephoto is extended all the way out
tracking animals when the light isn't good enough to use 1/640 at 400ISO (dawn and dusk, when they're out)
when you're in a place with a no tripod rule (I live in DC - tripods are not allowed in many places)
when you've been shooting and hiking for hours and you're tired
IS also helps lock in the image in the viewfinder (try focusing at 640mm in a strong breeze even on a bright day)

Tripods are great when you're taking a picture of a fixed scene. They don't help when you or the subject is on the move. Tripods are great when you have the time to set them up and don't have just a sec to snap the subject as its running away from being startled by you tramping through the woods.

No - IS lenses don't slow down the speed of the subject so it doesn't help with NASCAR or flying birds unless you pan or want motion blur.

Your images may not be as sharp as if using a tripod, particularly when as you go down in shutter speed - IS can only compensate so much. BUT, IS allows you to get the shots you would miss and other shots that would have been really blurry had you not had it.

.

I can't live without IS. That's why I bought the Pentax K100D. It has IS built into the body so that I don't have to buy IS everytime I buy a lens.

I was at Samy's Camera a couple of weeks ago and they had a "see through" (cut-away) model of a Sony Alpha. You could move the camera and actually see the sensor counter-move to stabilize the image. It was really cool to see it work "under the hood".

Pentax and other sensor-based DSLRs use similar technology.

I'll be interested in seeing the longevity of cameras with IS.
01/18/2007 11:54:47 AM · #24
I think what you have demonstrated here is that IS is a benefit under these conditions but not really a significant one as the pictures still appear to suffer from some shake and a tripod, faster lens or higher ISO… would also be needed to get a critically sharp picture.

What 420mm lens has IS?
