Canon 5D lens 16-35, 17-40, suggestions?

I'm getting the 5D camera and looking at getting the 16-35 or 17-40 lens for wide angle still shooting. Will either of these work for stitching? If so how many shots around (if anyone knows) also, if this isn't an ideal setup.. suggestions for the 5D anyone?
I know this is a PW forum, and this setup might not be supported by PW, but I also use PTGUI when needed...

Thanks!

Thanks smooth, I knew you'd have the answer ;p
I'm going to give it a shot, my only deal is that i've got the NN3 and can't do a full zenith shot... it sounds like a lot of shots/work, but since i've got this equipment now it can't hurt to try. (16-35mmL)

All that aside, wouldn't the 10mm be the ideal lens for a full frame?

The best lens "fisheye wise" for the Canon 5D Fullframe sensor is the 15mm Fisheye (6+TB).

The 10mm Fisheye would require the same amount of shots with less resolution (UNLESS) you have shaved/removed the lens sunshade/petal hood. If this is done, you can get away with (3+B) but again reducing the resolution even further.

Panoweaver 6.0 can handle the images shot with either of these lens.

Using a full size sensor Canon camera 5D. 5DMKII, 1Ds, 1DsMKII, 1DsMKIII.

The 16-35mm lens will require 6 shots 1 every 60 degrees at -30 tilt down, 6 shots 1 every 60 at +30 degrees tilt up, 1x Zenith +90 degrees and 1x Nadir -90 degrees. (@16mm) Total = 14 shots

The 17-40mm lens will require 8 shots 1 every 45 degrees at -30 degrees tilt down, 8 shots 1 every 45 degrees at +30 degrees tilt up, 1x Zenith +90 degrees and 1x Nadir -90 degrees. (@17mm) Total = 18 shots

smooth, is it possible to use the sigma 8mm on the canon 5d? If so, would you mind letting me know the needed shots/angles?
Also, if you've used the sigma8mm on 5d what kind of quality does it have?
Thanks!

awesome.. i think im understanding this hyperfocal distance deal... MUCH more useful than trying to use the "red dots" for focal points...
this will come in handy for landscape photos as well as standalone interior shots. The 16-35mm on the 5d is very sensative to Dof, just a tad off and not everything is in focus.

Thanks Dave!

btw smooth, have you thought about posting a table of how many shots/lens configurations, i see you've been asked that question numerous times.

Thanks again everyone!

one more followup, if the hyperfocal isnt listed on my lens should i goto a different fstop?
ex, 5d at 35mm shows 5.14mm at f/8
should i goto f/11 which is closer to being on my focus ring? or even to f/32

The answer is yes, 3 shots, 1 every 120 degrees. It is best to shoot with +5 degrees tilt. I have used the Sigma 8mm Fisheye on my 5D and now my 5DMKII you get good results but you are also wasting a lot of pixels to black because the image captured is a full round circle just like the Nikon Coolpix FC-E8, FC-E9 combo.

With a 5DMKII and Sigma 8mm expect maximum file sizes of around 7000x3500

Use the hyperfocal distance on the focus to maximize sharpness

Goto http://www.dofmaster.com/doftable.html

key in 8mm for the Sigma 8mm Fisheye,  select Canon 5d  select meters

click [Calculate]

Look at bottom of column "f/x" find the hyperfocal distance for

f1.4 = 1.52 meters

f2 = 1.07

f2.8 = 0.76

f4 = 0.54

f5.6 =0.39

f8 = 0.27

f11 = 0.20

f16 = 0.14

f22 = 0.10

f32 = 0.07 meters

Use the appropriate meter (distance) value by looking at your focus ring on the lens.  Find 2 scales  1 for ft  feet,  1 for m meters.  Dial the focus ring value to the | index mark.
