Cool pics

I use this lens for photography. The images are sometimes to soft but they look amazing. Its a heavy lens so it was hard to use it for street photography. Its as big as a zoom lens too so people notice you more. I do like what it gives me.

Amazing

If this lense is used on a C70 will it result in the 1.5 multiplier effect or be seen as a true 24mm?
Asked by: James
The Sirui 24mm f/2.8 Super35 Anamorphic 1.33x Lens (RF Mount) (B&H# SISR24RF) will produce an image circle that covers the APS-C sensor of the Canon C70. The equivalent focal length would be like using an anamorphic 1.33x 38mm lens on a full frame camera.

Is this only for the crop Z50? What about Z6/Z7?

Is this only for the crop Z50? What about Z6/Z7?
Asked by: Chris
It can be used on the Z6/Z7 however only in DX mode. If you shoot in FX mode, you'll see the lens barrel and need to spend time cropping it in post, killing your resolution. You'd be better fit shooting in DX mode and the sensor crop is done for you in-camera, maintaining the 4K UHD resolution. The camera's image can be de-squeezed for you in real time using a Ninja V or BMD Video Assist via the HDMI out.
