Aperture ring
Latest contrast to other destinations Nikon PC-E Nikkor 24mm f/3.5D aperture ring. The ring is electronically coupled to the iris, and it is easy to turn, so you have to always double check whether it position before you want a shot. The lens has its own depth-button button, it stops the opening to work.
Length scale
The goal is engraved with a distance scale marks the depth of field to f / 8, f/16 and f/32.The focus ring is wide and ribbed, and very easy to use. Focusing is internal, which means that changing the length of the lens and filter thread does not rotate against the background. Auto focus with not that objective.
Keep the version you can turn the lens
Tilt-shift beyond the PC-E Nikkor 24mm f/3.5D and 90 ° in any direction from the zero position. The press could be little green top has held down so that you may be able to execute them. Note that the only purpose of such a tab, and its counterpart, Canon has two, an independent rotation of the tilt and shift. We found that the Nikon lens is something very close to the lens of the camera shutter button - press to avoid this attention the wrong button.
A number of movements made with the goal as the objective, or even not be clear. In some areas these are trying to explain the familiar with the terminology.
Lens movement: up / down
First, the lens moves up or down to 11.5 mm. The upward movement is commonly referred to as "high", although the downward trend "case". A large knob with a worm mechanism used to move the lens and lock button on the lower side of the lens the lens to the desired position lock. Then, at the helm the sliding scale in increments of 1 mm.
That's all well and good, but why do you need this functionality in the first place? Well, if you are already photos of the buildings, high above all, I bet you seem to have this problem, at least a few times, the buildings are tilted, including the vertical lines converge at the origin over the back. This is achieved by tilting the camera to get rid of the preliminary plan and make the building fit into the picture caused. If you tilt the camera, the larger sensor vertical plane, and that is what causes the distortion is known.To your vertical vertical, you have the camera perfectly level, but with regular lens attached, it could mean that the tip is not covered by buildings, and you have too many unwanted foreground. (Or, if you are in shooting mode, you can lose the lower part of the building and the sky in the frame.)
