24-70 / 4L IS II

I have the 24-70 2.8 ii and I'm not exactly the most stable person. However I tested myself using it vs the 24-105 with IS at low shutter speeds, not supper low. But stuff like 1/50 1/30. And I couldn't see any difference. I wouldn't ever shoot at a shutter speed lower than that except for my Landscapes which are HDR so it's on a tripod. It seems to only make a difference on longer lenses for me.

This will change with the more megapixels we get but as of now I'd keep the one I have.

Plus, if Canon does it, hopefully they wait until they can do it right. Nikon put out their 24-70 2.8 with VR and it's not as sharp, not that the one they had was that sharp anyway. But now its even less sharp and heavier and in the 24-70 range most people aren't benefitting from IS unless it's video or if you really do go around shooting non moving subjects at 1/15 a second.

I'm a pixel peeper too. I want sharpness at 1:1 and it just never benefits me.

With higher megapixel cameras it does. Because I noticed it on the A7R when I owned it. The original one without IBIS. I had to use faster shutter speeds to hand hold it. Or else if I made a crop or a large print you could see it.

Some people completely deny that the issue exist. One time I said that on a YouTube video and a guy said, "Just stop... You heard that online and that rumor is not true." However, at the time I noticed it with my own eyes I had heard nothing about it online. Didn't even cross my mind when buying a 36 megapixel camera.

So, as we go up in megapixels, either Canon will have to introduce more IS lenses that can resolve even more detail than the ones now, or they will have to come up with something, like IBIS, maybe an even better version of it.

Especially when it gets to the 75 megapixel range.

Technology is moving so fast we'll probably be shooting 250 megapixels 6 or 7 years from now.

Lenses might not be as big of an investment as they used to be. Because I don't know how our current lenses are going to work with 75 megapixel cameras. And I'm sure the next 5DSR mark ii will probably be 60 or 70 megapixels.

I kinda wish technology would slow down and 50 megapixels could be perfected. It'd be nice if we could have 50 megapixel cameras that had the ISO performance of an A7S with 6K video and still more power to go.

But of course we never get anything perfected because it has to keep moving on.
