I believe the IS will be benefited more by the 5DS cameras and croppers. The pixel density on those cameras are requiring more than the 1/1 rule of thumb for shutter/focal length. Tack sharp requires much more shutter and the IS will help those guys out alot more than someone with a 5D3 or so.

I know for a fact I require 1/3 stop more shutter for tack sharp coming from 5D3 to the 5D4.

that's what they said about the Canon AE-1 too. every step of the way there is a certain group that yearns for the "good old days". i tell you if it weren't for digitial photography i would have never gotten back into it and i look at the advancements made in just the last 10 years and realize these are the good old days.

I'm not yearning for the good old days (which are almost never all that good). I'm even right there with you about digital - it makes almost everything better. And I won't leave a shelf full of prints and a bin full of negatives when I die. But it is a fact that many jobs are being automated into oblivion. Photography is getting much easier, by being digital - if it weren't, I could never do it. That's why there are so many photographers complaining about people like me shooting my friends for free...

I'm on the other side of that equation: part of the unwashed masses being let in by the advancements of the last 10 years.

Only when peeping at 1:1. For practical purposes (assuming no cropping) the pixel density has no bearing.

there will always be a benefit to shooting at the lowest ISOs. then there's this, which is pertinent now:

"Going forward, as sensors become more densely packed with pixels, we must constantly re-evaluate the shutter speeds necessary to stop the effects of camera shake to achieve the sharpest images."

That article is rubbish.

Don't forget that a slow shutter speed is often the whole point, so high ISO alone is not a fix. If I want the water blurred, then I want IS, not high ISO.

That's a good point but is IS really going to make enough difference to allow you to hand-hold blurred running water shots ... even with a wider lens?

If you can hand-hold a non-IS 35mm lens at 1/40s without softness from camera shake, and if IS gives you the benefits of three additional stops, then you can hand-hold a 35mm lens with IS at 1/5s. I'm no way any kind of expert on shooting flowing water but I thought 0.5s was the about the fastest shutter-speed that you might use for this effect ... so you are still a stop or two short, at least, and a tripod is still in order. I stand to be corrected on this.

It does make sense to me that IS is helpful for other varieties of slow shutter speed shot. I'd be interested to learn whether people are getting good blurred flowing water shots shooting hand-held (with or without IS).

Good luck hand holding 35mm at 1/40 with great consistency. Sometimes you may want some blur from slow shutter. Even for water , 1/10-2s is a nice speed to show texture. When you're planning, IS helps too. You can certainly pan without IS, but consistency goes down.

i think for water flow it really depends on the amount of water that is flowing...i'm sure there are some instances where 1/5 works, while others that it's just too slow...

here's a 1/5 shot...i used a tripod of course, but if you could get something like this handheld with an IS enabled lens over having to use a faster shutter speed, then why not put IS in wider lenses

I think it has to do with it's application. The 24/28/35 IS primes are very sharp and very small.

Still waiting on that 50f1.4 IS. Hell I'd love a 50mf2IS if it was as consistently awesome as my 35f2IS

See, I think 50mm f/2 IS will be decently sharp, lightweight and affordable. Not so sure about a 35mm f/1.4L IS or 24-70mm f/2.8L IS based on the Sigma Art and Nikon stabilized 2.8 wide angles. I think (I'm not sure if this is backed up by empirical evidence) that a wider angle would be harder to correct, i.e. The price difference between the Zeiss Otus 28mm f/1.4 vs the 55mm f/1.4.

1/5 is about as slow as i'll go, even on a tripod. I prefer 1/10 unless the water is running pretty slowly. Slower than 1/5s doesn't look all that good to me - it's over the top when the purpose is to show motion of the water..

If I have a tripod, I will probably shoot a waterfall at 1/2 - 1 second. But I'm often out hiking with just a 5D and 24-105, and I don't lug a tripod. And what I find is that you can get a nice vacation shot of a waterfall if you come across one. Like this - 1/5 second handheld with the 24-105.

IS seems like a nice to have feature on 85mm which I would use solely for portraiture but it's not a must have for me personally. I'm more interested in the PF/CA improvement and more consistent AF. If Canon nailed those two out of the park I'll most likely buy it.
