I don't see how we could realize a serial of good photos without being demanding on the method and without spending time on it Of course I sometimes happen to shoot one photo in far from ideal technical conditions because I prefer taking it anyway. The movement of the nodal point (as a function of the present focal length) of the zoom lens does not have to be linear. It balances the camera properly when mounted on a tripod. I am planning to measure the nodal points for all the lenses (and there are some good references available online in regards to doing this), but thought I might first check if there is some sort of standard database on this somewhere - or perhaps if other forum members might contribute the measurements they use for these lenses here. However, if shooting horizontally, the plates in your L-brackets may be offset from one another. But with certain wide angle zoom lenses of a complex optical formula like the 28-70/2,8 Nikkor for instance, the nodal point is very close to the front lens at 28 mm, gets farer at 50 mm and closer again at 70 mm !!! 16 0 obj From this point of view, perspective doesn't change.

If planning to travel to remote areas to capture panoramic images, storing the nodal point measurement values locally on your smartphone in a notepad app (or alternately in a traditional paper notepad) would be best. I wrote this for myself sometime back when I was considering buying a second quick release plate for my arca swiss style tripod which led me to investigate if doing so could improve the parallax errors in the panorama photo's I sometimes stitch together using Hugin open source software. After calculating the nodal points for several of my lenses, I got the itch to create another 360-degree panorama.
