So far, after-hour activity is not optimistic at all. Hopefully, $SPX is not worse than today.

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. Patent Information * Patent Publication No. 2011-81062 * Published 2011.4.21 * Filled 2009.10.5 24-70 f/2.8L II * Focal distance f=24.74 – 67.50mm * Fno 2.92 – 2.91 * Half angle of view 41.17 – 17.77 deg. * Lens length 206.42 – 177.53mm * Back focus 38.43mm * Aspherical 2 * zoom ratio 2.73x * MOD 0.38m 70-300 f/4-5.6L IS * Focal distance f=72.21 – 299.52mm * Fno 4.65 – 5.85 * Half angle of view 16.68 – 4.13 deg. * Lens length 142.64 – 201.84mm * Back focus 37.77mm * Aspherical 1 * zoom ratio 4.15x * MOD 1.4m 55-250 f/4-5.6 IS * Focal distance f=55.60 – 203.11mm * Fno 4.16 – 5.88 * Half angle of view 13.80 – 3.85 deg. * Lens length 162.05 – 202.41mm * Back focus 58.79 – 82.03mm * Aspherical 0 * zoom ratio 3.65x * MOD 1.5m Egami notes the 24-70 patent shows possible performance issues. You can check out their findings here. Quote 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. cr
