Hi folks,

I am about to get into this world of the virtual tour, so, I am choosing the right gear. Canon 5D Mark IIi, Nodal Ninja 4 R-D16, Autopano Pro 3 + Panotour 1.8, but what lens? Canon Fisheye 15mm or the zoom 8-15mm? Which one would be the perfect one?

Thanks for your help!

Using a 5D2 (i?? - -never heard of) in my eyes it´s wise to use the 15mm. If you KNOW you will use it with only 4 shots for being very quick take the 8 - 15mm. You need - as said - only 4 shots to cover a sphere, but you loose resolution.
So i wouldn´t do that.
Using the 15mm you anyway need only 6 shots when you make 5@-12° + Z. I don´t know whether the NN provides a click-stop for that. So the difference in speed is not remarkable. The difference in resolution is!

I use 5@-12° + Z all the time. here´s an example: www.360impressions.de/LiR_FE_Oben (a test-shot in a very narrow space)

best, Klaus

I think you may wfind you want Panotour Pro 1.8. The Pro version allows production of iDevice compatible tours as well as Flash tours and has other features too.

And if for any reason you want masking in the stitcher then you'll want to go for Autopano Giga.

Two comments:

1. Why do your prefer the Canon 15mm FE over the newer Canon 8-15mm zoom FE which would seem to be a more flexible option.

2. I had read that the Canon 15mm fisheye is very hard to fidn these days as it was discontinued by Canon some time ago. Or am I mistaken?

1) i don´t need 8mm on fullframe. It saves TWO shots - but it costs resolution by only covering a fraction of the format due to being circular.

2) Right, Canon stopped the production of the 2,8/15mm FE - but you can get it still, and at a remarkable lower price than the 4/8-15mm, which is around 1200.-€.

Btw.: i find 1:2,8 preferable compared to 1:4. Using a fisheye you can shoot max. wide open and have reasonable DOF nevertheless.
It´s a very sharp lens - i do lots of work with it.

PS: the 8-15mm is clever when you work with FX and DX cameras. Here you have FOUR FE functions. FF on FF, FF on DX, circular on FX and almost-circular on DX.

Hey Klaus, I just picked up the 15mm 2.8, just wondered if you've discovered a sweet spot in terms of aperture for max dof/sharpness?
Thanks

I usually use f8.

Thanks, and where do you place focus?

Depends on what i shoot, of course . . ;)

In large rooms and outdoors i usually use the right end of the infinity mark. Then it´s sharp from about 2m - infinity @f8 0r f11.
Ptreferably use the live-view to check whether your main-object is sharp.

No general rules.
