Hi,

I have a 40D / Sigma 8mm 3.5 and NN3 that I have been using to make 360 Panos. Now I am looking at picking up the Canon 5dMII, an NN5 and another lens. Specifically, I was looking at the Canon 16-35L, but would the 15mm be a better choice? Does it require any tilting on a full frame (or just 6 around)? I'm keeping the 8mm, but I have heard it has mixed results on the 5D, hence the new lens idea. I want to be able to take fast panos (like at the beach where waves are moving) and indoor architecture with better IQ than the 40D/8mm. Anyway, any thoughts or advice would be most appreciated.

sigma 8mm on 5DII will give you lower resolution than sigma 8mm on 40D. However, you only need 3 shots for 5DII. It will be good for fast moving action panos.
15mm on 5DII will of course bring the quality to the next level. Taking 6 shots around is still easily manageable.
A more versatile lens is shaved Tokina 10-17mm fisheye.

I'd say get the 15mm. 6 shots around at -15 degs plus one up at +60 degs. That should give you all the resolution you need with minimal shots and no issues about zoom movement But I know a lot of people rate the Tokina 10-17mm highly for the 5D when it's been shaved.

Many thanks everyone!

I think the 15mm sounds like a great addition (easier on my wallet too:001_smile:

Hi,

You could even try for 5shots with less overlay for the 15mm canon (24% instead of 36%) in busy places.

Some guys use Nikkor 10.5mm/f2.8 with adaptor on canon for 4 shots.

Normally I shoot 6 with D3 and 16mm/f2.8. I think the 15mm is a good choice. The 16-35mm at zoom 16 will ask you to shoot 2 rows with 8 shots each without bracketing shots.

Why the resolution is lower with 5DII& Sigma 8mm ... on 5DII you have 21 mil pixels .. on 40D only 10 mil pixels, is there any formula for this ?

Thanks

40D has a 1.6x crop factor. A full frame sensor with the same pixel density will have 10*1.6^2=25.6 MP. 5DII is just 21MP. So resolution is lower.
For technical formula of panorama resolution, see here
