Is the drop really 4 foot? compared to the woman and the B&H employee heights, it looks to me like at least 5 foot.

I was thinking on a second canon 15 2.8 or a sigma.
What are my possibilities? Anyone had both of them? Also how is Rokinon?
The Rokinon (a.k.a. Samyang) is a crop sensor lens. It'll fit on a full frame camera but you get a small rectangular image due to the built in lens hood. If you cut off the hood, you get a cropped circle in the middle instead, but still wont cover the whole sensor.
Mt Spokane was of course correct, I was tired! Parfocal is when zooming and focus breathing is when focusing!Quote"The 24-70mm f/2.8 mk2 is "so cheap"? Hmmm..."
Oh yes, take a look at this direct comparison,
- Canon 50 f1.2 $1,439
- Arri Master Prime 50 T1.3 $21,950
- Indeed Canons own Cine line, the CN-E 50 T1.3 is considered comparatively modest at $ 4,950
So our EOS lenses are so cheap partly because they are not parfocal.
15mm f/2.8 Fisheye II (non-L)
Yes, I kept my 15mm f/2.8 fisheye when the 8-15mm f/4 L fisheye zoom was released for three reasons:
The Sigma 15mm f2.8 is a more regarded lens than the Canon counterpart and it's still available.
I guess correcting a full frame 180 degree AOV is pretty difficult, but it can be defished with some pretty horrific drops in quality.
... but like all fisheye lenses....best used in moderation and infrequently. I like mine a lot, it's a lot of fun but it's not a lens I use often. In terms of distortion....it's a fisheye....yes it's a distorted view....it's supposed to be....lol!
15mm f/2.8 Fisheye II (non-L)
i can't imagine what could be improved in a mkIII. i use the 85 II and i absolutely love it.
LOCA or bokeh chromatic abberation is the only thing i'm not crazy about, but that flaw rears its head in even the best, super-fast lenses.
and besides, with canon's current pricing trend, i wouldn't care to pay 50%-75% more for what likely won't change much - image quality
There are a number of other lenses due for an update. I'm looking at you, 50mm f/1.4
Do a poll I'd say most 7D or 60D owners have a sigma lens or two whilst most 5D II/III and 1D owners will have mostly Ls. If consumers were tied into buying more expensive USM or L lenses or the crap basic canon zooms then they would switch to other manufacturers that have not and would not lock out 3rd party manufacturers.
I'll also add that the 4 stop IS is a big improvement. Many people still don't like to use IS but I can tell you when using the 600mm on a windy day, the IS stops the wind shakes 100%. Just takes the wind effect out completely. The IS on the MK1 lenses was pretty good at it as well but the new generation IS is WAY better.
They almost have to release an 800/5.6 MkII. The 600/4 MkII with a 1.4xIII gives an 840mm f/5.6 lens that's lighter and has better IQ than the current 800L. Can't imagine they're selling many 800s these days...
