Hello guys.  I found a company that offers a Canon to Nikon adapter for  Canon 5D for full frame fisheyes.  My question is Can I use the Sigma 8mm on this camera for 3 fisheye stitching with panoweaver.  My question is who is using this setup and what Head can I use that is Nodal point ready for this setup.

Thanks in advance

I disregarded your other thread on same topic.

When you buy a Sigma 8 specify a Canon mount.  When they ship it should already fit without an additional adapter.  It worked fine with our Canon 20d with the EFS mount.  I did read that the Canon 5d only uses EF lens type mounts.  So when you order the Sigma 8 make sure you specify the EF mount.

ONLY ISSUE -  When you are in the camera shop ask the sales rep to mount it on your camera before you buy the Sigma.  The lens AND camera have CPU's that talk to each other.  The gold signal contacts on the lens and camera must match AND the Canon camera uses a control access PIN code that is sent to the lens that when recognized says that that Sigma has paid for the license fee for that lens. 

Sounds silly but if the camera does not recognize the Sigma 8 lens.. then the lens is rendered manual and the F-Stop, Aperature size, shutter speed must be set manually.  The values will not be displayed on the cameras LCD.  In other words the lens will not be automatic.

We use the Canon 20d.  Our sales rep tested out our Sigma 8  and it performed automatically. (apparantly fees were paid).

How does the full circle Sigma 8 image fit on the Canon 5d ?  Don't know have not had the opportunity to find out.

Best would be to discuss it with your camera shop sales rep.  That way if something does not work.. you can always return the lens.

Just a thought on the matter

Thanks Dave.  The Canon 20D is not full frame CMOS correct? Therefore I cannot get full circular images.  So using the 5d or Kodak DCS full frame I can take full circular fisheyes to stitch 3.  Do you recommend the Peace River Head or what head would be best for this setup?

Thanks for your input

I have not yet checked the camera size dimensions for the 5d. Never looked at the Kodak.   But I would think that a pan head with adjustable left to right and forward / backward adjustment will work just fine.  You are going to have to calibrate pan head, camera and lens anyway.

A 3 or more click stop and head quick leveler will make your life easier.  Agnos Pan Heads comes to mind.  Kingpano is another.  And then of course there is the Kaidan.  Then there is that one that is tailor made just for your camera/ lens ---- its really expensive $10k. hmm forgot the name.

True.. the 20d is not a full frame sensor.  We use a old Kaidan Kiwi990 pan head.  It only works because the 20d body dimensions are the same as the Nikon Coolpix 990 (out of service now).

If we upgraded to the 12mpxl Canon 5d we would have to retro fit our Sigma 8 and buy a new pan head. I have not seen images from a 5d yet so not sure if its worth the upgrade.  All our imaging content is sized for broadband and the 20d seems suitable.  Not sure we would have any benifit going to a 12mpl camera yet.

The optimum set up for speed and ease of stitch is the Canon 5D and Sigma 8mm Fisheye. This is best fitted to an Agnos MrotatorTCPS on top of a sturdy quality tripod. You will shoot 3 shots in rotation and stitch with Panoweaver 4.0 in Circular Fisheye mode.

Too up the image quality you would use the Canon 5D and either Canon 15mm Fisheye or Sigma 15mm Fisheye lens. This is best fitted to an Agnos MrotatorTCPS on top of a sturdy quality tripod. You will shoot 4 images in rotation and one up shot. (Down optional) and stitch with Panoweaver 4.0 in Full Frame mode. Using the MrotatorTCPS will allow you to use the 90 degree up and down shots and these would be shot in the last position of rotation (position 4). The MrotatorTCPS is best suited because no matter what lens you are using circular fisheye, full frame fisheye or reticular, all can be fitted. Not to mention you can upgrade you camera body without having to upgrade your Panorama Head. The Agnos MrotatorTCPS can be ordered directly from www.agnos.com delivery is normally 10 days standard or 3 days express.

A very good majority here on this forum use Agnos products with great success.

As others have stated get a canon mount Sigma 8mm for a Canon body or a Nikon mount Sigma 8mm for a Nikon body, same price.
I have a 5d, Sigma 8mm (Nikon mount) and adaptor rings and I've yet to make a pano with it as it's the only nikon mount lens that I can't get sharp focus with an adaptor. If you already have a Nikon mount Sigma 8mm get a Nikon d70 or better still the new d200. Then get Nikon Capture as it has the best CA removal tool (which the Sigma exhibits) that I know of.

Smooth,

We bought and use our Sigma 8mm on a Canon 20d.  Are you saying that my Sigma 8 is also usuable (full functions) on the 5d too ?

Dave

Hi Dave,

The Sigma 8mm you have is the same as mine. It is a Canon EOS mount, thus it will work 100% on "any" Canon Digital SLR and any Canon SLR with EOS mount. So yes, it will work correctly on a Canon 5D guaranteed. But it will produce full circular images not drum style. Much the same as what you got from your old Coolpix only 12.3MP though much better glass.

For the others thinking of using an adaptor to mount a Sigma 8mm fisheye (Nikon Mount) to your Canon EOS forget it! Buy a Canon EOS mount Sigma 8mm to start with.

Simon,

Nice to here you got the 5D, I also plan for the same (waiting for the after Christmas price drop) My Canon 10D is still going strong but would really love the Full Frame sensor as I have my Canon L Series lenses that I could get the most out of. Are you happy so far with your 5D?

Regards, Smooth

Smooth,
Very happy with the 5d but disappointed that I'll probably have to buy a canon mount sigma 8mm! I use it mostly with the Canon 16-35 lens which is a great lens but does exhibit some light fall off with the bigger sensor when stopped down which doesn't concern me. CA can be also be an issue even with an L lens which is a slight disappointment. Nothing a client is ever likely to notice in reality but it would be good if Canon could add a CA adjustment to their software similar to Nikon Capture.
