Re: Preston Fiz3 not matching marks

Do you have the corresponding ring selected in the options on your handset?

Hey Saul,

The pre-marked rings for the Preston FIZ HU3 are mathematically created, whereas the majority cinematic lenses are hand made and even the focus markings on 2 identical Cookes s4 50mm will differ, especially at the Close Focus end. The Preston Handunit is mathematically calculating the distance between set points to then predetermine where the focus points should be (mathematically) but this isn’t always the case.
Other factors - The gears on the motors - Are they the correct gearing? Are they clean? Yes, These do need to be cleaned & yes it makes a difference
When doing a standard calibration, and turning off the focus ring so you can use blank rings, do you get a difference each time you calibrate?

Any chance lens mapping is turned off?

Is the amount the lens is off consistent?  You could always slide the motor up or down a bit on it's mount while engaged to the lens to compensate.

Preston Fiz3 not matching marks

Saul Oliveira
 

Hello: 
Preston HU3 with MDR-2, G4 converted.
After mapping a lens the premarked ring does not match the marks on the lens anymore. Did a Soft Reset and  the Focus knob Calibration and nothing improved. It’s always the same amount of offset and to the same direction, less in the D ring more towards the A ring. At 2 meters it sets the focus at around 2,10 more or less. 
Any ideas?
Best regards

Re: Settings on Cinetape

Ben Tubb
 

I haven’t used a cinetape in quite some time as I’ve happily swithed to CineRT. But I always kept the setting firmly on -1. It resulted in what felt to me like a quicker refresh rate and a faster display, which I preferred to a slower, stable one.

Re: Settings on Cinetape

jeffrey truong
 

Whilst i havent tested this myself i understood it as:
1=changes when actor moves more than 1 inch. Once they are past the inch they need to move more than one inch backwards for the display to go back. But if they move 0.9 inches the display wont change
-1=shows chenge immediately which means that if they are wavering at 1ft he display will quickly jump between 1' and 1'1 making the display difficult to read from fast change.

I should test this.

Re: Settings on Cinetape

Saul Oliveira
 

I remember reading this in the past, never understood the minus values. 

I understood the 1 value: “maintains the displayed distance 
until the distance change is greater than 1 unit”, but I don’t get the -1 setting: “maintains the displayed distance until the distance change is plus or minus (+/-) 1 unit.

Re: Settings on Cinetape

jeffrey truong
 

From the manual: It's is a rounding system.
 
Adjusting the Display Resolution (Starting at Version 1.06)
The Display Resolution is the amount of distance rounding-off that is shown on the Cine Tape Measure
display. Reducing the resolution (Increasing the rounding-off) is useful when a more stable display is
desired. The resolution setting is the third item accessed through the Power-up Menu. This setting shows
as “rE x” or “rE –x” where “rE” is the abbreviation for resolution and “x” is the amount of rounding-off. The
displayed minus sign (-) is the graphical representation for plus or minus (+/-). The four resolution settings
are; 1, 2, -1 & -2.
The ‘1’ setting is the normal (maximum) setting and maintains the displayed distance
until the actual (physical) distance change is greater than 1 unit.
The ‘2’ setting maintains the displayed distance until the actual (physical) distance
change is greater than 2 units. Only even numbers are displayed.
The ‘-1’ setting maintains the displayed distance until the actual (physical) distance
change is plus or minus (+/-) 1 unit.
The ‘-2’ setting maintains the displayed distance until the actual (physical) distance
change is plus or minus (+/-) 2 units. Only even numbers are displayed.
To access the display resolution adjustment, unplug the power cable, then plug it back into the Cine Tape
Measure while pushing and holding the Select / Adjust knob. The brightness setting shows initially.
Momentarily push (click) the Select / Adjust knob twice to advance past the close focus adjustment to the
display resolution adjustment. Adjust the resolution to the desired level by turning the Select / Adjust
knob. Then lock the setting into memory and return to normal operation by momentarily pushing (click) the
Select / Adjust knob

Hello:
how do you use the -2/+2 setting on the Cinetape?, what does it exactly do?

Re: Tv Logic VFM-055a Aperture

Saul Oliveira
 

They say the new F-5A is closer to the 58 than de 55 is, in terms os peaking, aperture, focus capabilities. 
Have you tested it?

Re: Tv Logic VFM-055a Aperture

Zachary Kertesz
 

It really depends on the camera, some people prefer to have it heavily cranked up but I find this gives a false sense of security for super critical and shallow work. 
Arri cameras I keep mine at -4 to -6 just to the point where a spectral will vibrate the eyes. 
Other cameras have other levels.

Go “Old School”, run a tape measure & get marks?
 
Steven i’m not taking about methodology, i’m Talking about an specific monitor and it’s adjusments. But since you asked, yes, I still run a tape, a laser, mark the actors, the dolly and get space references across the set, but I also use a cinetape in some cases and a monitor to quick check focus in some positions, mostly on wide open long telephotos when not having DoF for both eyes can ruin a take if you try to do it only by judging measures by eye or when even the cinetape isn’t useful; or to quick check a finished shot if in doubt of the focus. I use the monitor as another tool like thousands of asistants in a world where the sensors are becoming larger than monitor screens itself, and even Preston Light Ranger is a tool to exclusively use looking at a monitor.

Re: Steel vs Carbon Fibre vs Aluminum rods

Trevor T
 

I use aluminum whenever I can because they're lightweight (and cheap). But I've experienced aluminum rods being a little more flexible than steel, so if for instance I have to mount 3x Preston motors under my lens for a zoom that doesn't have a lens support… I would prefer steel. (Ideally though, I'd rather use aluminum rods, use a lens support, and separately mount my motors above the lens so gravity works in my favor.)

@Phil's idea of Titanium is great, I hadn't heard of those and I'm excited to try them out.
