  1. Canon 8-15mm fisheye data

    #1

    Does anybody have the numbers on the the Canon 8-15mm fisheye lens?

    And if not, then what procedures and documenting are recommended in my
    taking such measurements to add to the Entrance Pupil Database
    and then updating the nodalninja Camera and lens settings page ?

    I have plans to try it on my EOS 40D and NN5 head.

    Thank you for any reply.

    Hi and welcome to the forum,

    http://www.easypano.com/forum/displa...1&TopicID=4162

    for lower rail setting. If the "tooth of the circle saw" cuts to the right, you have to move the camera to the right looking through viewfinder. If it cuts to the left, move to the left mm by mm. At least you should have 3 sets for example: LRS 54 cuts to the right, 55 has no teeth at all, 56 cuts to the left. 55 will be your lower rail setting.
    This method is because of the workflow more exact than simply to focus down to the logo and and center the focus ring to the middle. This helps for the first orientation. Use for example f22, go down to -15º, focus to the rotator, and take the shots around. The easiest workflow is to take a set of three settings in one go, 54, 55, 56 before importing the pictures to the computer and PTGui Pro to stitch them. Import, align, go to "advanced", "optimizer" and set "heavy and lens shift". This is default in the new beta version of PTGuipro. After optimizing use "Control points" of the top tab and click "delete the worst control points".

    In Create panorama check the panorama settings and set them to 360 x 180. In "create" use ".mov" as output setting. Open up the mov file, move down to the nadir and check the rotator. you can easily zoom in to check it more exactly. Once you are used to this workflow, it is easy to do and you get a better result than just using the logo.

    for upper rails setting. @ zoom 8 I would start on or near the red ring and move slowly backwards.

    Regards,

    Hello Hindenhaag,

    I'm familiar with the thread, but there's no discussion about the Canon 8-15 at that page.

    Yes of course cause it is a very new lens and only a few people have got it in their hands till now.

    Success,

    Hi Kelly,

    would be nice. Cause I am a Nikonian. I can test Nikon Equipment. But I have little chance to get my hand on Canon equipment.

    My offer to all dutch new Canon Nodal Ninja Users: you may come to see me, I can show you how to find the upper and lower rail settings for NN panoheads from NN3 MKII, NN4, NN5, M1, to R1. Inclusive Nadir Adapter use with hard- and software. You may test the Pole System and I can give you some info about the use of PTGuiPro Software to get a good result from a brilliant hardware and software. For nothing, for me it helps to get a certified new database for Canon NN Users for the new models. Just send an IM. Bring your camera and lens, a USB stick and on we go.

    Regards,
    Heinz
