Have you one of the new 24-70 f4 canon lenses, Is it good

Of course IS doesnt account for subject movement but thats not the point
I dont think anyone ever said it did 

Its just silly that people continuously argue in a very aloof manner
"that IS is not needed on wide to normal focal lengths"
Fact is it helps in alot of situations and no its not going to help freeze the subject
but there are many other ways of dealing with that such as flash

personally all else being equal I would rather the lens i'm using have IS than not

now that being said the only lenses I use alot that even have IS are the 24-105L and the 70-200f2.8L II
since the 24-70 does not have IS i prefer to use the 16-35 I can still shoot this lens comfortably at 1/20th second and keep the shot sharp and 1/10th if i really try.

I would LOVE an improved 16-35 with IS (let all the dogma preaching sheep now give me a lecture about how I dont need IS at those focal lengths and I must have no idea what i'm doing)
If a good quality 24-70 f2.8 with IS came out from either canon or sigma I would more likely use that more often
(I cant live with Tamron build)

and as for canon putting IS on primes, I think its awesome, I wonder if this trend will translate to more future L primes. I certainly hope it does i can only imagine how cool a 35mm f1.4L IS would be.... or a 50f1.2L IS and 85 f1.2L IS, 135 f2L IS

I had high hopes for this lens, as I'm not 100% in love with my 24-105.    I read with disappointment  Roger at LenRentals confirmation of the very poor image quality at 50mm, and just now read the new detailed review at SLR  Gear, which pretty much put the nail in the coffin for me.   Even at the other focal lengths, the full frame blur plots don't have the edge sharpness I would expect in a brand new state of the art,  high dollar "L" lens.   The other big concern is the lens they did the analysis on was the best of three they tested, the other two were far worse.

Key takeaway from their review   "the lens' performance at 50mm stands out as unacceptable, especially when you consider the lower-priced option here still costs $1,500."
