  1. help with Samyang/Rokinon 8mm & R1

    #1

    Hello - I've just ordered the R1 Adjustable Tilt Ring Mount Package & EZ Leveler II.
    I'll be using the Rokinon 8mm with Nikon.
    Does anyone use this combination? I've tried without success to find info on the NPP for the
    Rokinon lens.
    Any other info & tips you can give (such as # of shots & angles etc.) will be very helpful
    since I am new to this.
    Thanks

    It is my understanding that you will need to shoot 6 images around plus a Zenith and Nadir + Nadir patch in order to cover the entire sphere. Why did you choose the R1? Are you going to shoot only cylindrical panoramas? I believe a NN3 type pano head will work better for you. If you want to shoot 4 around without a Zenith, you should use the Sigma 8mm lens. Tilted up 5 degrees you will get the sphere in 4 shots but will still need a Nadir patch shot in order to cover the entire sphere. I could be wrong about your lenss since I have not used it, instead only read about it.

    Thanks for the info DennisS. I thought the R1 would be best from what I've been reading. Could easily be be wrong.

    The R1 is a wonderful rig. I use one with a Sigma 8mm lens and a monopod. Your lens has a 180 diagonal picture while the Sigma has a partial 180 circle (with the sides chopped off). I tried the Sigma on my Nikon D3S (a 50th birthday present to myself from myself) and get a full circle. What a waste of pixels.

    Wait until somone who uses your same (or close) setup comments before passing final judgement. If you want to return the R1, I am sure your NN dealer will work with you.

    Samyang 8mm works for R1 in outdoor panos.
    For indoor, NN3 is preferred.

    What is the difference between outside and inside panoramas? Are not the number of shots required to close the sphere the same? 6 (maybe less) + Zenith + Nadir + Nadir patch?

    what is at the zenith for outdoor pano? They are just sky. an offset in NPP at zenith is not affecting the stitching.

    Nick,

    Indoor panoramas usually (not always) have a boring ceiling, so following your logic no Zenith shot would be required. Just clone the surrounding areas in Photoshop.

    Standing in the middle of a field with nothing but a clear blue sky overhead makes for a boring panorama. If you stand at the edge of the field next to a tree or building or something else interesting, you most likely will need a Zenith shot. What are the chances all outdoor panoramas have a clear view of the entire sky and that sky is cloud free? Clouds moving across the sky will require a Zenith. For the Samyang lens, relying on cloning the sky may leave you with panoramas that are not a complete sphere. If someone were to purchase just one pano head for use with the Samyang lens, they cannot go wrong with the NN3. My personal opinion is that the R1 is a mis match for the Samyang lens when shooting spherical panoramas.

    This is the only way I was able to use the R1 with the Rokinon (Samyang 8mm):

    Even with a big blue bowl sky, the Sun needs to be shot. Can't clone it.

    And it's always more interesting with something in the zenith and nadir that needs the camera to stay at the NPP. And it's not always practical to shift the tripod to shoot the nadir. But that's just my opinion. Others can probably think of better ways to shoot.

    And my limited experience with the Samyang 8mm showed you need more flexibility than the R1/R10 gives. So I think an NN3/4/5 would be a better option for the Samyang and other lenses.

    Or you could just remove it all together. Nobody will notice. I posted this before as a test for all the pixel pushers who look so close for errors that they miss the big picture. It took a couple of days and several hints before somone noticed that there is no sun in this panorama.

    I don't think anybody suggested that you should dispense with a zenith shot when using an R1. Nick simply pointed out that an outdoor zenith shot taken with the R1 didn't usually present stitching difficulties because the sky is along way away and parallax therefore isn't an issue. Of course there will be situations where nearby features protrude into the zenith area - e.g. overhanging tree branches - in which case more care will be needed at the shoot and in the stitching/post-processing. There's no doubt that a spherical head such as an NN3 will be much more versatile and convenient, but skies are not always plain sailing with a fullframe fisheye even then. Moving clouds look nice but can cause severe stitching problems.
