Lenses / Focusing on L lenses vs LII
« on: January 17, 2013, 06:31:47 AM »
Hello, I talked with canon tech service about adjusting the focus of my 16-35L, 24-70L and 70-200L to my %D mark III and I was told that the micro adjustments of the 1DX and 5D mark III are only useful with LII lenses since it adds a third focusing parameter that the L series lack.
Is it true the there is not worthwhile adjusting my lenses?

Thanks, the lens I'm talking about is the Sigma AF 15mm f/2.8 EX DG Fisheye. So if I understand correctly,  I can make 360º panos with a single row of 6 vertical shots, not needing to make two more rows of images rotatin up and down.

Do you have an example of a 360º pano with your lens at 15mm on a fullframe?

Lenses / Help with 360º Panoramas
« on: January 16, 2013, 05:04:37 PM »
Hi,
I want to take 360º panoramas with my 5D. Can I use the sigma 15mm rectangular fisheye or will I need a circular fisheye?
If it can be done with the sigma 15mm rectangular fisheye, how many shots wilI I need?

Thanks.

Of the ones you have, I would definitely take the 200L. But I think you will brake the barrel of the 24-100 trying to go wider. I would buy the 16-35 or the 17-40. Just this trip will make them worthy. Order by internet at B&H and pick it up in SF fed-ex or ups. They are so much cheaper than here in Europe. For example, you can have the 17-40L for $699 (533€).

Hi there, would it be possible to make 360º circular panoramas for virtual tours with this lens at 15mm or the sigma EX DG 15mm?
Does the canon5d mark III correct the chromatic aberrations of the sigma?
