All this IS debate is totally moot.

The only thing some (including me) can say is that we are pissed paying for IS that we don't want/need due to our style orientation. (+carrying the weight and bulk).

That's cool I see your point ... but a cheap fifty without IS already exists. Why would you be pissed if a more expensive version became available? No one is forcing you to buy it. In fact the 50 1.4 offers good value too. That's 2 cheap 50 primes. Now what Canon need to do is simply improve the 50L and we will all be happy! Btw I am convinced there is nothing wrong with the 50L and most of the hoo ha is all baloney. What is an issue is the price.
Move along nothing to see here!

Why are so many lenses being fitted with IS?

Because as sensor pixel densities go up, without it you would need to shoot at 1/150 to get a sharp shot with a 50mm lens.

Is the penny dropping yet?

+1 I saw it very clearly going from the 1d3 to the 1d4, I had to go from 1/1000s to 1/2000s to get sharp action shots. And now with the 1d X, it's somewhere in between, but I set my min.speed to 1/2000s anyway.

And for low light it's the same, it's very seldom I go under 1/250s with a lens shorter than 100.

...and do you really need the pixelcount? Doubling the Pixelamount just gives you minor resolutiondifference in x/y, but you gain a lot of negative effects. That's the reason why I still use the 5DC... it's a lightgathering beast with 12 MP on a FF-Sensor.

And yes, the new Canon 24 IS or 28 IS are not that big, but they have a whopping Price around 700$. For a normal 2.8 prime... I think this is way too much. Without IS ist would be 200$ less, I think.

Why does everyone think IS is *the* masterkey to filmmaking? Every serious filmmaker uses manual lenses and If you want to have steady shots you can even get a gyrostabilizer for the whole camerasystem.

Don't get me wrong, If canon would make both versions, everyone would be lucky... but this won't happen, so everyone has to pay the higher price for the demands of a few.

I don't disagree with you about the price, but can you substantiate that 'everyone has to pay....for the demands of a few'? Opinion on here may be divided, but I disagree that a majority don't want it, especially as the posters here are a fraction of Canon's market.

In any case, I think the bigger issue here is not that Canon is implementing IS on their new lenses, it's the price premium they see fit to levy for the privilege. But that is their direction as a company, like it or not.

Yes, because much better IQ, build, focusing accuracy and speed is 0% of the price increase of the new models. ::)

IS on a 50mm? Why?

Because their fast zoom in this range doesn't have IS, so rather than go f2.8+IS they do it the other way around: 1.8+IS :-\ ... and they'll probably also design and market these as video lenses.

That's cool I see your point ... but a cheap fifty without IS already exists.

But w/o a decent af system...

How about light weight and compact size? No, I wouldn't do landscapes at 1.8, but IS gives me the option to shoot in lower light, maybe at a lower ISO or at a smaller aperture for DOF. Carrying a tripod isn't always practical or possible when hiking etc.

Adding IS will not make the lens lighter or smaller.

Maybe not, but the new 24 and 28mm 2.8 IS lenses are still compact and light relative to zooms or their faster aperture equivalents, is this not true?

Most Canon non-L prime lenses are quite out of date. Tech changes fast - smaller and faster. Still, adding IS will not decrease the lens size. I'm sure you recall cell phone sizes 5-7yrs ago. I still believe primary reason buying prime is fast aperture & shallow DOF. IS was introduced to prime due to video feature in DSLR. Again, I can't speak for everybody else. I prefer f1.4 with or without IS. and yet, sharp @ wide open.

How about adding IS to a lens that really needs it. Take the 135L for example....  ::)

Regarding lens size, there are limits to how small in size and weight a lens can be made to cover a particular size of sensor, regardless of the march of technology, as long as we are using glass optics. I am not disputing that IS makes lenses bigger and heavier than a non stabilised equivalent, however the point I was trying to make is that the new primes (or old ones for that matter) offer a  compact and lighter alternative to a zoom, whether they have IS or not. To me, the IS is another tool for helping get a shot under certain circumstances where I could not have done so previously, it's not the solution to everything, nor do I expect it to be.

Or 85L III IS.  That would enable me to sell my 50L, maybe even 35L.

Let's not forget the other unforgivable reason they may well put this lens out.  Profit.   Canon is a profit center first and foremost.  That is there duty and they will sell thousands and thousands of these lenses with the IS feature included, making??? Profit... Good plan...  ;)

Exactly!  That's why I said Canon is a profit center first and foremost.  It's their duty and responsibility to their board and their investors... It's what they exist for and there is no knocking that! :)

Yes, but they should always invest in the right direction. Otherwise they'll fall like others did...
especially the camerabusiness is a great example for that.
