I have a canon 10d with a 17-40 zoom lens and a 15mm fish eye.
I wonder if anyone can let me have the setting out of the nodal points ?
Any help for a beginner much appearciated.

Daz,
What pano or spherical tripod head are you using?

Haven't got one yet. as they appear to be a bit overpriced when all you need is a bent bit of tin. An exaggeration I know. Am thinking of the panosaurus which seems more resonably priced.

Keep looking on Ebay I got one used for $400. and it's a real nice one, new it would have been $700.

But seriously all you need for a spherical head given a 10d and a particular lens is a L shaped piece of steel with 2 holes.... OH yes thats $700 thanks very much.....
Anyone got the setting out noted above????

just another point it looks to me that the design of the 303 sph is flawed as the point of vertical rotation is not at the nodal point but on the axis of the centre of the tripod.
this means that the nodal point of the lens will move out of postion as you rotate the camera vertically
A minor point I know but it could have been solved by having the second moving plate at the lower level.
and when your paying that much money......

The 303 SPH is not flawed - it works quite well.
The vertical rotation does not move the lens off the nodal point as you setup the nodal point above the center of the head. You can even take the up or top shot from the tripod. While expensive - B&H Photo sells it for about $480 US, it's well made and works very well.
Be careful about buying a panosaurus or whatever it's called as they say 3 pounds is the weight limit. A 10D with lens is over 3 pounds.
A homemade solution is probably best and the cheapest.

I would recommend you follow James' tutorial on figuring out your own setting:
www.panoguide.com/technique/lamppost_test.html
I use a Canon D-Rebel with an 8mm fisheye. I just followed his instructions along with the instructions from my Kiwi-L panohead.
