    Nodal Slide for DPM2

    Would this Nodal Slide work with the DPM2?
    Nodal Slide DMP-100 - Products - Sunwayphoto-a superior photography accessories manufacturer in Shenzhen China
    or..
    Do I need a longer rail?

    Thanks

    That should work just fine, it barely needs much 'slide' at all. I got the RRS 192 Precision Plus slide package which is overkill but offers up some other possibilities as well.

    I measured 30mm. I've seen a couple of users post 32mm. A range of 5mm is negligible and you're bound to have useable images anywhere in that range.

    So any rail that'll allow you 1" to 1.25" will do the trick.

    That sunwayfoto does have the advantage of a spirit level which is not common in very short rails.

    Thanks everyone.
    Looks like I am going to save some money and get the Sunway foto rail.

    newbie alert..
    So this is the first time I am using a nodal plate.
    I am using a RRS Pano head. If I use 30mm I assume if I have the slider at 0 right in the center of the Pano head then slide it back 30mm I am good to go?

    Re: Nodal Slide for DPM2

    how I do it:

    center the lens in the clamp on the slide
    frame a shot by moving tripod so a near vertical (15') and a far vertical (100') align and are in the center of the frame.
    pan to one side so the verticals are near an edge. move the slide in the pano clamp until they align.
    pano back to center and verify alignment. quite easy with live view

    when the camera is set on the lens nodal, you can pan back and forth and the vertials, near and far, will stay aligned

    You've got it.

    Here's a good tutorial that should help clarify things.

    Kirk, thanks for that tutorial link - it is well written. Really Right Stuff also has a tutorial on their web site for use with their pano gear.

    Yes, the tutorials posted are essentially it, however, if you are in a rush, depending on the software you use, the outcome can be very different. I use the RRS kit myself.

    Ultimately PTGui Pro, I have found to give the best results, and approximate positioning (close but not perfect). This was much better than the results I achieved with Photoshop CS5. Just thought I'd add this in here!

    It's hard to understand why Adobe has such a poor implementation of pano stitching but that's certainly the case. I've also been using PTGui for the last year and it's definitely worth the investment in my opinion.

    Re: Nodal Slide for DPM2

    I would be interested in the vertical arm being offset for the nodal point. Would the value be different between the lenses of the DP1M and DP2M, or are they essentially the same?

    Thanks,

    Nick

    Re: Nodal Slide for DPM2

    value will most likely be different, but you have to test to be sure. nodal is a property of the optical construction of the lens

    Re: Nodal Slide for DPM2

    So would you offer separate plates for the DP1M and DP2M or is it really only commercially viable to offer it for the DP2M?

    Re: Nodal Slide for DPM2

    that would have to be the case.

    the adjustable slide in the first post looks like a very good option

    Re: Nodal Slide for DPM2

    To the OP (and anyone else that might have an answer!) - the nodal slide you linked to in the original post - since the DP2M lens sits on the left end of the camera, and since this end is the end with the "L" bracket to attach the camera in vertical orientation, will the end of the slide not be in the bottom of the photo since the lens is so close to the slide? Or is the angle such that it is out of view?

    Just curious as despite this being the shortest nodal rail, I am wondering whether it might be too long. If that is the case, a multi-purpose rail (Multi-Purpose Rails DPG-210 - Products - Sunwayphoto-a superior photography accessories manufacturer in Shenzhen China) and a bi-directional clamp (Bidirectional Clamp DDB-53 - Products - Sunwayphoto-a superior photography accessories manufacturer in Shenzhen China) may be the required set-up.

    Thanks

    Nick
