Fixed lens: not infinity stop in manual focus, fly by wire focus.. What does it mean?

[Van Din]

Given that it is autofocus and manual, it will not have an infinity stop in manual focus mode, although it is set up for gearing. We have a VERY new way to "fly by wire focus" for the fixed zoom that all will appreciate. It is the magic of that lens (along with the resolution).

I believe it just means that because the lens is "Fly-By-Wire" the focus ring will turn continuously, instead of stopping when it has reached infinite, as in a manual lens.

I guess this means that you could use it with gearing, but you wouldn't want to because it wouldn't be repeatable. Instead you would want to use the "fly by wire focus" control for pulling focus.

I don't understand the advantage of not having an infinity stop.

Cheaper and internally controlled. (HVX-200)

 

[J. Eric Camp]

In the internal controls for a fly by wire the system will generally scroll to find the sharpest point. I assume that a hard stop at the infinity point could damage the internal motors. You can make your on hard stop in your gearing.

I don't know if this has been discussed in another thread....I
I work with documentaries and I would like to see lenses developed with AF because in certain situations, it is invaluable to forget about focus pulling.
I know the 8x fixed lens for Scarlet has AF, but I prefer to build a modular systems with the 2/3 rd brain.

Can anyone tell me which RED lenses are expected to have AF?

The only RED AF lenses are the 8X that is on the 2/3" SCARLET, and the FF35 lenses (three zooms, a telephoto, and 1.4x and a 2x extenders).
