  1. RD10 canon 7d sigma 4.5mm NPP

    #1

    HI
    Still a newbie, I have taken out the rd4 rotator from my nn180 and installed the NN Ultimate R10 with 2.5 static, clamp my sigma 4,5mm following the R1 pdf file set up. According to the pdf file the NPP for 2.5 degree with three shots is 3.7 for my canon. I do have parallax problem with this setting. I will have to experiment but anybody can share values with me?

    Thank you

    OOps figure out I was +2.5 degree and not -2.5 degree, I have reset the setting to 0 degree and will post later if NPP value are working for me

    R10 setting is different from R1. Don't mix them up.

    We listen. We try harder.

    Thanks Nick, but cannot find any NPP value then for the RD10, any lead?

    The Sigma 4.5mm fisheye hasn't proved to be very popular and you may have some difficulty in finding anyone else using one on an RD10. You should just learn how to set up your pano head yourself. It's straightforward to do since all you can do is slide the camera forwards and backwards for any given angle of tilt. Just nudge the camera forward/backward a mm at a time and check for parallax until the parallax shift is eliminated (or at least minimized). See this tutorial.

  6. A lot of testing

    I spent a few hours trying just about every setting possible on 0 degree with three shoots. I have tried from the minimum to the maximum NPP value with each mm option. The best result is at 0.7 but still not perfect. I will like to share with you that I obtain perfect result when I shoot 4 pictures at 0.7 setting on my sigma 4.5mm with canon 7d RD10. For someone not looking for parallax problem at the upper level of the picture almost all setting works at 3 shoots! which mean intuitively that outside pictures with a pole will be quite forgiving

    If you are shooting on a tall pole, then a few mm from the ideal NPP position will make no visible difference to the stitching. I do wonder, however, if you are distinguishing between parallax errors and stitching errors in the upper level of the panorama image. Stitching errors are often due more to poor stitching than to parallax effects. What stitching software are you using? Adjusting your head to the NPP should take no more than 10 minutes or so.

    I found some R10 settings with Google search at this page
