Frequently Asked Questions
Is this lens usable on full-frame Canon bodies, and how does the image circle behave on both sensor formats?
The Rokinon 8mm T3.8 is compatible with both APS-C and full-frame Canon EF mount cameras. On APS-C sensors it delivers the classic fisheye circular-to-edge distortion. On full-frame bodies the 180-degree angle of view produces a more pronounced circular fisheye effect with visible dark corners — factor this into your creative decision if you're shooting full-frame.
What does "de-clicked aperture" mean for video work, and why does it matter on this lens?
A de-clicked aperture means the iris blade ring rotates smoothly and silently without the tactile detents (clicks) that photo lenses use to step between f-stop values. This lets you pull aperture during a shot — reducing or increasing exposure on the fly — without the audible click being captured by on-camera or nearby microphones. It's essential for clean run-and-gun and documentary video work.
Does this lens autofocus, and how does manual focus feel in practice?
This is a manual focus only lens — there is no autofocus motor. The focus ring operates smoothly and the 8mm focal length's inherent depth of field at T3.8 means a large portion of the frame is in focus at once, reducing the precision required for follow focus work. For video work, manual focus is the norm on cine lenses and the broad depth of field makes this one of the easier lenses to keep sharp.
How does the removable lens hood affect shooting in bright conditions or tight spaces?
The removable hood is useful in most outdoor shooting scenarios to reduce flare and protect the front element. In very tight spaces — interiors, vehicle interiors, architectural work — removing it gives you a few extra centimeters of clearance and can allow the lens to get closer to subjects or walls without the hood entering the frame.
What's the minimum focus distance, and can this lens be used for environmental portraits or must subjects be at distance?
The 8mm fisheye's geometry is most dramatic when subjects are close to the lens — bringing a face or object within arm's reach exaggerates the perspective distortion in a way that can make for striking, character-driven environmental portraits. The minimum focus distance is close enough for intimate subject work; shooting exclusively at distance underuses the lens's creative strengths.
