Nick, I believe a filter factor of 1.2 is 4 stops.

Thank you Shane, It's completly the oppisite of what I thought it would be. lol Just figured that one would turn the knob towards the direction on was focusing to. But now that I think about it, before internal focusing the lens would physically shorten in length (towards the camera) as you focused towards infinity. Thanks, Chuck

I think this is the right forum for this question. Could someone tell me the direction the follow focus knob is turning (looking at the knob from the side) when focusing toward infinity. This is assuming a standard cine lens. Thank you, Chuck

Hi Robert, Would just like to point out that $100.00 in machine shop time (not to mention the enginerring involved) is about the time the machinist gets his first cup of coffee and turns the mill/lathe on. Just how it is.

Hey Glenn, One film that always impressed me for the fighting footage was Walter Hills "Hard Times". In fact the pacing of the whole film is incredible. Not to mention the acting, lighting etc. etc. Chuck

Ahhhh.... I you sure about that?

Yes. The viewfinder has a ground glass area in the central portion of the frame just like a regular ground glass system in a cine camera.

Angenieux made a few of the 9.5-57 f1.9 zooms with side finders but they are pretty rare. Nice lens though. And of course there are about a gizzilon 12 to 120's out there with side finders.

Hello Nick, You got it right about losing proper back focus. If you gel behind the lens you will optically increase the flange focale depth by appx. 1/3 the thickness of the gel. (.0015") Not to much to worry about on longer lenses but it wreaks havoc on wide angles. Also if you recollimate the lens for use with a gel behind it, you have to have one in there at all times even if it's just a clear one or you will not be able to achieve infinity focus. Chuck

Hi Matt, There's not much to it. Perhaps if you could tell me your voltage and current (amps) requirements I could lend a hand with the choice of battery and charger.

The first site listed has some basic and good info on the use and care of newer types of rechargeable cells. http://www.rchobbies.org/lithium_battery_breakthrough.htm http://www.a123systems.com/html/technology.htm http://www.all-battery.com/index.asp?PageA...mp;Category=262 http://www.hobby-lobby.com/lithium-polymer.htm http://www.rchobbies.org/lithium_battery_breakthrough.htm http://www2.towerhobbies.com/cgi-bin/wti00...25&I=LXHDJ1 Here's one more http://www.hobby-lobby.com/chargers_lipoly.htm#Xtrema

What mattebox?

Yeah that's right. A bare bulb.

That sucked, and it's so hard gluing all those little pieces back togeather.

YOU DID WHAT !!!!!!!! Was that with a bastard file? lol

Hello Sam, As a former 30 year camera/optical tech. I would say the knowledge you would gain from such work would be of great benefit to a career in the industry.

15mm rods are used either on 60mm or 100mm on centers 19mm rods are 105mm on center

"C" mount lenses are for 16mm cameras, their flange focal depth is .690".

LOL Mayby it's caused your upside down in NZ! Speaking of apes... I read that if you put a baby chimp and a baby human on a table surounded by clear glass at the same level as the table a chimp will not crawl out over the glass area but a baby child will. I'm putting my money on the chimp. Chuck

Hi Nick, I always got that confused and thought it was the other way around. That is, that you got slightly more reach past the plane of best focus. Mayby I'll finally remember it this time. lol Chuck

Michael, Have you or someone else you know taking apart the spindle assembly? Just wondering if some pieces are missing in there. Anyhow it's a real basic mechanical piece as a whole and any camera tech or machinist would be able to fix it right up. Even if they had to replace the oilite bush or make a sleeve for a worn axle it is really no big deal. Chuck Oh yeah, and I agree with Charles (always liked that name) that the chance of a spindle being bent is rather low.

Good evening David, Almost but not quite from ground up. Jimmy Beaumonte and I worked togeather at his shop in L.A. at he time of the start of the "Empireflex". The basic VistaVision movement was from an existing camera. What we did in L.A. was to breadboard the movement on a piece of tooling plate to find the best location for sprockets, rollers and where to position the Arri 35 mags that were used for the camera. Some work was also done on the mirror reflexing componets. After that Jimmy and his wife Hillary went up to Lucasville to finish the project. Chuck

Pointed on one end and beveled on the other. Use for removing emulsion buildup on the gate.

Hi Devon, It's a camera mount and lens support (mainly zooms) for a 35 llc/b with the motor sticking out of the bottom.

I think they still focus backwards which is tough on the puller if you don't have a follow focus device which is reversable.
