If the USA prices are lower than rumored, or even equal, those primes are going to sell many, many copies. I can't imagine the image quality of the 600 and 800 will be anything short of excellent. Canon doesn't really make bad primes these days, at any price point.
As far as I can tell, they traded on all the "right" things. Don't try to make it physically short. Keep the MFD long. This has been the recipe of the excellent old primes like the 400/5.6 and 300/4 non-IS. Further: Perfect use case for DO element. Make the build quality adequate but not L grade. In theory, they have done nothing that should compromise the image quality. I am a bit anxious about the DO element, but on the positive side it has always meant high resolving power wide open, even field and low CA. All good in my book.
One thing not mentioned yet, that I have seen...
If a DO lens can be made for this cheap, and the image quality is good, that means Canon found a way to make DO elements at a much lower cost than in previous generations. Maybe there is a hope for more DO lenses in the future that are affordable.
But, this could also be a result of making the lenses f11, which reduces the size of the DO elements and their production costs.
Canon has had two levels of DO lenses for a long time. There's the 400mm DO L lens, with superior optics and a price to match, and the 70-300mm non-L DO lens with lesser optics and a much lower price. This is not a new thing for them.
Not quite a fair comparison. The 70-300 was around $1,400 MSRP new, and it's a very early DO version and an older lens (2004 iirc). The image quality from that thing was abysmal, but more likely due to being a zoom with DO element.
If the new f11 DO lenses offer image quality as good as the 400 DO at f11, then maybe Canon has lowered the cost of making DO elements that are worthy for replacing traditional elements.
I guess whether the comparison is fair depends then on whether the image quality of these new lenses is any good, esp. compared to the 400DO. I have my doubts. But we’ll see.
I might have been a bit incorrect about the 70-300. When stopped down to f11, 300mm, it's actually not far off from the 400 DO at f11.
EDIT: the link is not working properly to the lens settings, but just manually put the 70-300 DO to f11 and the 400 DO to f11 with camera set to 1dsIII.
Hopefully the new f11 lenses will be as good as the 400 DO, which in itself is just barely good enough compared to their non DO L tele primes, which are far sharper and higher contrast.
