Canon EF 24-70 f/2.8L
A few reports around the globe about the EF 24-70 f/2.8L being officially discontinued. This was an inevitable event.
I’ve had at least 2 suggestions that have said the version II delay has been to dump excess stock of the version 1. How plausible is that? I don’t know.

There has been no mention of another delay for the version II. It’s still slated to start shipping in July. You can still preorder it at B&H for $2299. Do not expect any sort of price drop on the version II for quite some time.
Here we go again
More information has trickled in about the “thorn in my side”, aka the Canon EF 24-70 f/2.8L IS II. A new version of the updated lens started to make its way to the folks lucky enough to test the lens out. There have been upwards of 5 different variations of the new lens. It’s still reported that there is no IS in any of the prototypes. One design change that has apparently been seen is a fully internal zoom function, we’re not sure if that is with all the prototypes.
I won’t even hazard a guess as to when it will be announced, though it was suggested it has been pushed back on various occasions.
I can see the collective eye rolls about this post already. I post about 2% of the stuff that comes in about this lens, I understand you’re all sick of reading about it.

- 1D/1Ds line is about to be amalgamated. (Name Unknown)
- Full Frame
- 12 fps
- 61 AF Points
- New Battery
- Available in March
- Price unknown, but I suspect more than the 1D Mark IV
2012 is shaping up to be an interesting year for EOS.
The previous spec lists are pretty much bang on.
I have received no word of a new lens being announced at the same time. I suspect they’ll stagger announcements. The 24-70 f/2.8L II is the only lens being mentioned. Possibly in November. This isn’t included in the [CR3] rating.
It’s coming, really!
We posted the filed patent of a 24-70 f/2.8L II way back in October. However it has now been published as of April 21, 2011. The big omission appears to be IS. I think it’s safe to say the lens is coming soon.
Other Lenses in the Patent
A couple of other lenses appear in the patent. A 70-300 f/4-5.6L IS, which has been released. Also appearing is a 55-250 IS lens. This could be a version II of the current lens. It could also shrink to 200mm at the long end.

Egami notes the 24-70 patent shows possible performance issues. You can check out their findings here.
The performance does not seem to be so good. The spherical aberration is delivered to less than +-0.2mm in all conditions at the outskirts. The astigmatism exceeds 1mm extremely badly in the short distance. The distortion is -4% of barrels type in the wide side. In the short distance, the distortion is +5% of lozenge type in the tele side. The chromatic aberration of magnification is corrected well.
