Rokinon Cine DS DS14M-C 14mm T3.1 ED AS IF UMC Full Frame Cine Wide Angle Lens for Canon EF

The "DS" designation stands for dual scale, meaning that the markings on opposite sides of the lens are identical so that one may determine which is which The right-hand side of the keyboard I am pulling my focus from one hand to the other. There is only one position for both the aperture and focus rings on all DS lenses, so you will not have to adjust your focus when you switch As well as the lenses, they are colored To make intercutting footage easier (without having to grade shots that come from different lenses to compensate for color differences), footage from different lenses should be matched. For those of you not interested in this detailed information, or if you're just buying one (not the whole set), you can jump right to cinema and save some money!

To answer the question of how to switch from T to Fstop, here is the best answer I am Dave Perry, Cinematographer LLC PRO, and I am a year into learning the ropes of Cine. These are cinema lenses, which have a T/stop scale, rather than a F/stop scale. There is a ratio between the focal length of the lens and the diameter of the front element known as the F/stop. As a result, it really does not tell us what amount of light is The ratio is simply a measure of the size. The T/stop in T-stop refers to the amount of light that is transmitted through the aperture, therefore the "T" in T-stop That's it. If you light a set for T/3, regardless of the focal length or manufacturer, it will always be the same T/stop value. In the case of a shot that calls for a 50mm lens and a 85mm lens, it is safe to set the 85mm lens Light was used for 1 since that was what it was As a result, we have Approximately the same amount of light as a T/1 goes through the 5 Zeiss 50mm. The set was light for T/1 if it had a 5 85mm Cooke and aperture, but both lights did not need to be changed. There is a lens swap at 5 and a call is made. It has been almost eight months since our last meeting A stop doesn't account for the loss of light all lenses endure, while the T/stop does, which means that a T/3 is appropriate. As an F/2, 1 is roughly equal to 1.

Using the 13 mm focal length of the lens, you get a focal length of 14 mm. There is an attachment of type Micro 4/3. With a 14mm lens, you can take pictures from a longer distance than with a 35mm or 85mm lens. There is still room for a 4/3 attachment in all those cases.

You cannot do that, according to me. Several of the elements in this lens are curved.
