Hi.....Professional friend,

Actually what is Playing with the perpective .......while shoot making..............

Perspective is the perception of depth between foreground and background objects.

It is normally sensed by comparing the size ratio of images. Size ratio is decided

by the view point distance, not by by change in the focal length.

But when tele lens is used, view point is foreced to be from the object, making

size ratio among the images of the objects at different planes to get reduced.

Since size ratio is reduced, objects appears to be close to each other. This

has resulted due to change in the view point. since you have used telelens

your are forced to away from the object. Since this happens when tele lens

is used, many think that focal length is responsible for the change in the

perspective. Keep cool. Do not argue, if you director says use tele to

compress the perspective. Use tele and go back.

Sorry but that's not what I was asking - I was asking if anyone's seen and adaptor to put PL lenses on a Nikon stills camera....

I do not think it will work, becuase PL mount lenses will not have

covering power to fill the area with good image for 35mm

mm still camera format

Has anyone ever seen this done?

When a Nikon lens can not be used for infifity focus, what is the use of adapting it for PL mount.

But there are 35mm movie camer which can directly go with Nikon lenses - Photosonic make

oups sorry, right, 172°8 is even less a difference, it gives you 1/50 instead of 1/48... It's not noticable, for me.

 

This shutter angle is designed for working with discharge lamps such as hmi on a 50 Hz voltage when runnig 24 fps as to avoid flickering, it should not be noticed as diffrent from 180 °, to me, as a matter of image look...

I perfectly agree with the views. Idea of using 172.8 shutter angle is to have 1/50 shutter speed when working 24 frames per second, when supply frequency is 50 Hz. and HMI lights are operated with magnetic balast, so that all the frames will receive same exposure (each frame will experience 2 enegry peaks of lgihts equally). If we can run the generator at 48 Hz, the shutter angle can be 180 deg.

Where I can download operation manual for ARRI III. I have gone through

Arri Web site. But it is not listed.
