Q: 6. 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.
