The Bower 24mm T1.5 Cine Lens for Olympus 4/3 Mount Camerasis a wide angle prime lens that covers full frame DSLR Sensors. The lens is a wide angle lens for shooting with full frame sensor cameras, and can be used on APS-C and 4/3 sized cameras. The lens features a maximum aperture of T1.5, which makes it a very fast lens that delivers a crisp image with low chromatic aberration across the imaging field. This is accomplished by using 13 optical elements in 12 groups with two aspherical elements. The lens also features multi-coated optics for good contrast, flare reduction and optical performance.

The internal focus design that keeps the front of the lens from rotating, which allows it to work with accessories and available lens mounted filters, such as a polarizer, while allowing you to focus as close as 10.2 inches from the image plane. Designed for shooting HD video, the lens features built-in iris and focus gears, allowing you to use available follow focus units and iris motors. A silent iris design allows you to pull aperture smoothly during a shot while shooting video. The tulip-shaped lens shade is removable and you can attach optional filters using the 77mm threaded front mount.

Q: 3. What exactly is the difference between these Cine DS lenses compared to their equivalent non-DS lenses?

But what is the difference in the DS lens that makes it cost about $200 more?Also, what different markings are there on the lens that make it obvious this is a Cine DS lens compared to the previous models? If you were looking at the two side by side, how could you tell the difference?

The focus and aperture gears are exactly aligned so that the user does not have to re-adjust his/her follow focus when swapping out lenses. 2) The new Cine DS lenses now feature dual focusing scales, one on each side. 3) All of the Cine DS lenses are tested to be color matched to provide the same color & contrast in video production.

A: Yes, this lens will mount on any EF mount Canon camera and will provide great looking images. However, this lens is designed for cinematic use and both focus and aperture are adjusted manually via the rings on the lens. There is no communication between the lens and the camera, so auto-focusing and aperture adjustment from camera are not available.
