Fixed focus lenses?

[Mr. Paul White]

For run 'n gun work, without AC, truly handheld and deep DOF, any tip on fixed focus lenses?

Hi,

Your joking? Right! If your serious then the Pelling 8mm in PL mount could be what your after, set the focus to 60cmm stop down. Just make sure there is no dust on the front element!

Wasn't the Kinoptic 9.8mm fixed focus? You see those around in PL mount.

NO. This lens focuses if I remember correctly.

Mayby Mr. White meant to say fixed focale length. Then again mayby not. lol

Oh yeah, I believe also that the 9.8 focused. I think it was the 5.7 mm (for 16mm film) that was fixed focus.

Generally for handheld work without an AC pulling focus, you'd probably first try and get a decent f-stop to work in, use a wide-angle lens, and thus have some depth of field to cover you. Then you might set the lens to some hyperfocal distance, or a ballpark distance that the subject will be on average.

Or as an operator, I would get a close and far eye-focus and memorize roughly how much I twisted the focus ring, so when it came time to make a correction in focus, I could turn the barrel by a certain amount that I knew was close to being correct and hope the depth of field would cover me. It's not unusual, for example, to walk the camera handheld up to someone and turn the focus ring until you hit minimum, if minimum was something like 2 1/2' on that lens, and then stop getting any closer.

We do alot of so called Run 'n Gun news style. If we are used to using lenses like Canons YJ19 series, what lens is going to give us the same flexibility on the RED?

[Martin Drew]

I wonder if you may be best off with a S16 lens shooting 2K, that will give you similar DOF to 2/3 inch. I am presuming shooting 35mm in a single operator ENG style is just going to be too onerous. It may work if you have a LOT of light and keep with a wide lens, but S16 may make your life easier.

There are certainly variable focus versions of this lens, Century did one for example, but I am sure I read somewhere that the original Kinoptic was fixed focus. I will have to see if I can find the reference.
