Do these binoculars have the ability to have the IS turned on for 2 or 3 minutes or do you have to hold the button down still ?

Yes, and it's a show stopper for me. I wouldn't mind if it had a 2 minute timer or some such, but it means you have to hold them in a particular way so you can keep the button pressed. Besides, I can always carry a mess of rechargeables. If I'm going to pay $600 I want a better solution. Disclaimer: I didn't buy them, just tried them at the store and found the button push to be annoying.

The button has to be held down to keep the IS on. This prevents it from being left on and using up the batteries

You have to hold down the button for the IS feature to work on these binoculars. It is an easy button to press, well located, and really isn't a big deal even for long periods of time.

You have to hold down the button. But it isn't a big deal. You almost do it automatically.

On mine, you have to hold the button down. This keeps you from running down the battery

The button need to be depressed to hold the IS on. This is no problem with ordinary viewing, as one is holding the binoculars anyway. If it is hooked up to a camera by some sort of stand, a mechanical method of holding down the button would need to be devised.

Two AA batteries are included with the binoculars. I'm sure battery life depends on how often and how long the binoculars are used. For bird watching, a few minutes at a time, while walking the dog, I assume that I will get a year or two from the batteries.

Not really. The button works two ways - you can "pulse" it with a quick press, or press a little deeper and it'll lock in the "on" position.

They are on timers. They go off 4 hours after you turn them on, they are amazing!!!!

Yes, you just have to hold the on button for 2 seconds. If you hold it again, the light comes back on and the must goes intermittent. The instructions tell you how to do it.

Two AA batteries are needed. Battery life depends on how often and how long you use the IS button. I am an avid hunter and part-time guide, so I am constantly viewing and assessing game, for long periods of time. I have gone through the batteries in 3 weeks to a month, sometimes less, but I use the button above and beyond the average person. I always carry two to four extra batteries in my backpack, so it's really no big deal. I have had the batteries last for a good 8 months during the off season. I believe that they could last a year or two, if used conservatively. The Canon 12x36 IS is simply the best binoculars I have ever owned!!!!!!!!!!!!!!!!!! Two AA batteries are needed.

None. They work perfectly. The only delay is when you first turn them on. They take a couple of seconds to synch with the base. Typically, I turn off the headphones whenever I'm done using them to save batteries.

You can keep the lens open for as long as you like... push once to open, and it won't close until you push the button again. I took 15-minute exposures of the sky at night on a mountain in Hawaii!!!!

I believe you need to hold the button down for 10 to 30 seconds before letting go!

I try to not turn it on in bright light, I've heard it could damage them. I love the binocs, we use them to find hogs. Not as clear as more expensive ones but good for the price.

No. You don't need to hold the IS button down. You just need to push down once and it will work for 5 minutes and then it will automatically turn off.

They turn on for 30 minutes, then off to conserve the battery. Then the remote allows you to manual turn on for unknown amount of time.

Good question. The instructions say to hold the button down for 3 to 4 seconds. Sometimes it works, often it doesn't. I got tired of the inconsistency, so I plugged the unit into my master power control unit. Now I just turn it off with a dedicated switch on the master contol.

As the other answer says, "immediately". In any case, less than a second. If you hit a button twice VERY quickly (which I've done in a frantic situation) it may not be awake, so don't wait until the last second to make a correction.

No need to hold the button down. You click it once, it turns on in the last mode you used (strong, medium, strobe). If you quickly click again, it cycles through the modes. If you wait for about a second to the next click, it turns off.

You have to hold the button in. Unfortunately it doesn't have an on/off button or switch.

One of the on buttons turns them on and they stay on. The other on button turns them on - and then turns them off 4-6 hours later. It would help if the words on the bottom (on, off, on) were in a different color so you could read them easier!
