I am disturbed when I find craft relegated to inferior consideration; I believe that the euphoric involvement with subject or self is not sufficient to justify the making and display of photographic images. SigmaRebates Lens plates are designed to fit long collared telephoto lenses. Ultra-wide to short telephoto?! Definition: points of an optical system for which an incoming ray, directed at a nodal point, leaves the system with the same direction. For 5D Mark III L-bracket, the offset is 15.5mm, meaning I have to subtract 15.5mm from my vertical orientation measurement to get the landscape oriented one. If you have difficulty seeing a bright spot or disc, just point the back of the camera up at the sky and look into the front of the lens. The entrance pupil is the image of the limiting aperture or diaphragm, as seen through the front of the lens. It's even really simple because it's done with the LCD screen or the viewfinder of the camera if it's a reflex as we'll see in the page dedicated to the entrance pupil!

This is not of much importance, and even of no importance at all with long focals because: It is fundamental if you have at least a foreground and a background to shoot. Record the position of the nodal rail in your clamp, such as "Clamp centered on 49mm rail mark," the lens being used and (if using a zoom lens) the focal length setting of the lens. FYI the correct term is either the centre of projection, optical centre or "no parallax point", the most widely used term: "nodal point" refers to something else! That site tell me that the entrance pupil of Nikon 50mm f1.4 AF is 52.8mm in front of the film plane. By a system of adapted perpendicular stages, you'll have to place the camera on the head for its rotary axis and the nodal point to overlap.

Rotating the lens on its nodal point allows you to avoid those parallax errors, ultimately leading to a better panoramic image. To see the image at 72dpi as that is what loaded well into Flickr click here. This 4.5-inch lens plate is made of T6061 aircraft-grade aluminum. For primes, I understand that the nodal point will be fixed, so I could find the point once and mark it, but for zooms, since the nodal point moves when I zoom, a method that can be easily replicated in the field would be best. http://www.swissarmyfork.com/lens_table_1.htm, And read the text at top of the page. Sh), (TOP Liveview mode makes it simpler than ever. I found I could use a flash bracket mounted on top of my existing 50mm quick release plate to gain the necessary offset, though the length of the bracket in front of the lens meant it entered into the frame on wide angle shots. .), (AMD don't forget to mark on the paper the position of the front glass of the lens.

Is this variant of Exact Path Length Problem easy or NP Complete. Some lenses, notably fisheyes, do not have a single no-parallax point. The same who, by the way, would have explained how the nodal point is not that important! ), (BIF I'll stress again, but I already explained why above, that the less you shoot close subjects, hence beautiful and distant skylines, the less the problem of the nodal point (of the entrance pupil) is raised. Preparatives Figure 1: The nodal points of a thick lens. The acid test was to get the overhead wires to line up with the correct sag in them. Typically speaking, I usually calculate the nodal points for the shortest and longest focal lengths of a zoom lens. The foreground and background will overlap exactly in the same way, whatever the direction of the camera, from the left to the right (image here).

With a lens plate, you reduce the risk of the telephoto lens dragging the camera setup down when mounted on a ball head. One needs two vertical objects as reference points, like a street lamp post From this point of view, perspective doesn't change. <> It is used to find the nodal point on a lens while on its center of rotation. check that the height of the laser ray matches the one of the lens axis. We can clearly see a gap between the streetlamp (foreground) and the dome of the Institut de France (in the distance) when we rotated the camera (photo 2) without taking into account the way we set it on the head unless we even shot with the camera in the hand. It balances the camera properly when mounted on a tripod. If I've got a nodal slider, though, I still need to find the nodal point of the lens. Zeiss 100mm 2.0. It seems that if you don't try to set your camera at the nodal point, certain software like PTGui or Autopano Giga stitch better the images in the central part of the final image, rejecting quite intelligently the unavoidable defects at the edges. The result is speaking for itself. You'll have artefacts along overlap zones between two consecutive photos, especially visible in city landscapes where regular geometric lines are the norm. Regardless of what you call the no-parallax point, it is easily found by trial and error. Zeiss 35mm 2.0 Therefore, I have to ensure that the rail is clamped into the index rotator's clamp at the exact same position each time if I ever entirely break down the setup.
