Related Questions and Answers

Q: 1. Can someone please explain or help me to understand how to read the hyperfocal scale on this lens? I have never had a problem using hyperfocal scales on any of my other lenses, but this one is quite perplexing to me, there are so many values on it.

A: If you are old school and know how to use the hyperfocal scale on manual lenses, then work as you have before. If you wish, you can also use the innovative hyperfocal indication line but really it is meant for others. That is because, ever since auto focus lenses came into use, they have mostly come without manual aperture scales since they had no place for the scales to be applied. Therefore a generation of photographers has grown up not knowing what they are for or how to use them. With Irix's hyperfocal line, the new user determines what aperture they are using, moves the focus ring to line up the aperture number on the Irix hyperfocal line with the lens focus mark. Then they look to the aperture numbers on the traditional scale to see the hyperfocal distance or the area that is in acceptable focus. To old users it is not necessary, to new users it is very helpful.

Q: 9. Would I be able to put a clip on mattbox on this lens to use a polarizer or would that vignette?

A: The diameter of the front of the IRIX 11mm T4.3 Cine Lens (Canon EF, Feet) (B&H# IRC11EFI) -- not to be confused with the filter size -- is 95mm which is a very common size to which to attach a matte box. Yes, it would be possible to do so. Given the ultra wide nature of the field of view, however, there will of course be at least some amount of vignetting regardless of the size of the filter, but that is unavoidable.

Q: 10. Can the aperture be controlled with a dead adater like the FotodioX Pro TLT ROKR Tilt-Shift Adapter for Nikon F Lens to Sony E ?

A: The aperture in the IRIX 11mm f/4 Firefly Lens is only controlled electronically. So the Fotodiox tilt/shift adapter would not be able to control the aperture.
