Does it have an aperture lever to allow me to focus wide open and have the camera stop it down when I shoot? The picture does not show this.
Asked by: John
This is a manual lens, both the focus and aperture are controlled on the lens itself. You will be able to adjust the aperture on the lens.

Can I use this lens on a super 35mm digital camcorder like the Sony FS700?
Asked by: Landmark P.
You can if you buy an adaptor. This lens is EF-mount, meanwhile Sony FS700 has Sony-E mount. It will have some cropfactor, though. I'm guessing 1.4 or 1.5x? Meaning you'll probably see it as a 200mm.But it does work, and its a fantastic lens for its price.

Is this lens compatible with the Nikon D3500?

Is this lens compatible with the Nikon D3500?
Asked by: Lynn
Yes, the Rokinon 135mm f/2.0 Lens for Nikon F Mount with AE Chip is compatible for use with the Nikon D3500 DSLR camera. Do note that this is a manual lens, so you will have to focus the lens manually. However, as the lens does have an AE chip, it will provide automatic exposure metering in Auto, Program, Aperture-Priority, Shutter-Priority, and Manual modes, and the LED in the camera's viewfinder will illuminate for focus confirmation when the camera detects you have focused on your subject. It will also provide EXIF metadata to the camera.

Why does this lens not come with an AE CHIP for Canon?? For traits I'd want the focus beep confirmation and the ability to shift aperture through the camera.
Asked by: David G.
Rokinon offer both versions and different price points.
