Nodal Point Database

Symphotic

Hello, Everyone!

Here are some approximate numbers I ran quickly this morning. Please correct these if you have better numbers, and add more lenses. I'll produce and post a nice database for everyone.

Test conditions: Two vertical lines, 1.5 and 10 meters from camera. Leveled pan head with nodal plate (RRS)

24-70/4S
24mm: 100mm
35mm: 95mm
50mm: 90mm
70 mm: 75mm

50/1.8S: 75mm
35/1.8S: 75mm

If anyone has done this work for the 14-24/2.8G, please post!

I will be doing some of this again over the next few days. I have both the single row RRS pan head as well as the multirow pan head from RRS. I did a little research with the D810 with the 50mm f1.8 but no longer have that body or nodal settings. I will be using the D7200 with a Sigma 35 Art, a Nikon 50mm f1.8, a Nikon 105G f2.8, and possibly do some testing with the Nikon 70-200 f4 at 70mm and 135mm to start with. The latter will be for a multirow panorama that I want to see just how much detail I can get in such a large print. The 70-200 f4 testing maybe time wasted but there is only one way to find out. I have a place in mind that is a solid rock wall that won't be moving in the wind so that problem is not a problem at all.

When I get back from my current trip I'll test the 24-70/2.8 S.

It took 7 frames to build the stitched panorama that is sized to print a gallery wrap of 36x84" using a D7200 with the RRS pan head on a leveling plate and RRS nodal slide. Nodal point for a Nikon 50mm f1.8 G was 65 on the scale. All work done in Photoshop's Photomerge and resizing tool. This was only a test to see how it would workout and it looks good on my computer. The acid test was to get the overhead wires to line up with the correct sag in them. I never achieved this trying to use the 70-200 G f4 lens. No matter how well the vertical lines line up the images always had the lines barreling up instead of sagging. Still going to work on it but for now both the Sigma 35mm f1.4 Art and the 50mm G 1.8 are my two lens of choice to stitch with. I did a similar print and had it printed using a Sigma 35mm art and it printed out well. To see the image at 72dpi as that is what loaded well into Flickr click here. If all goes as planned I shoot a rock cliff wall at a TN state park tomorrow using same setup. I have secured the needed wall space to display at a local business where the theme complements the business. I will post any findings using a Z7 with a 50mm S lens when I find the subject I want to use it on. I have a place to hang another mural of 54"x144" and have that on the bucket list to do. Once I figure out the multi row setup I'll post information on those too.
