Impressive photographs. I see you use the 1Ds 5D mark III, 5D and 6d. Which of these has the best image quality, discarding built, focus...

Thanks.

It seems the primary benefit you espouse is for covering incompetence! I assumed, you being an "ART" photographer, would have a basic understanding of exposure and your cameras capabilities.

Missing an exposure is not incompetence it is just an error that everybody in this forum , except you, has committed.

In my experience Hdr with only one shot is a very destructive process if you start up with just one shot on a limited dr camera as my 5D mark III.  So, for me,  HDR only works well on static subjects. I wish my 5D III would ha 14 stops DR.

Anyone knows the real difference in DR on the 5DIII between ISO 100 normal and 200 with hilight tone priority?

Shoot Raw + Large fine jpeg. You'l have the jpeg files and raw to cover from exposure errors. Basic raw developing is really easy.
You'll see more the difference between the two cameras when developing raw.

Have a good one.

Lenses / Re: Help with 360º Panoramas
« on: January 17, 2013, 12:07:08 PM »
I do have some experience with landscape panoramas. I use PS's photomerge and a RRS nodal slide. The thing is that I've seen a business opportunity with 360º panoramas (with some floor and ceiling) and web based virtual tours and I have no idea how to do it and the best possible setup.
I talk about the Sigma 15mm f/2.8 EX DG Fisheye because it seems a good and affordable lens which I could use not only for the panoramas since I don't like circular fisheyes. So if the Sigma 15mm f/2.8 EX DG Fisheye on my 5D markIII,  will allow me to do this kind of panoramas shooting just one row that´s the lens I would buy.

That's why i asked. It didn't seem too convincing. I don't know elsewhere but Canon support in spain sucks.

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.

That's me...

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?
