Simmod SIMple Fit Follow Focus Gear – Large (L)

Say goodbye to 3D printed plastic gears and never heat a Delrin gear in the oven again!  Take the guessing game out of fitment issues and say hello to the SIMple Fit Gear!

The SIMple Fit Gear is the worlds first seamless follow focus gear that combines an all-aluminum gear with an interchangeable compressible insert, allowing you to fit any lens. SIMply select the insert size that measures closest to your lens body circumference and attach the gear. It’s a SIMple, elegant, flexible solution with the professional durability and performance of an aluminum gear!

This kit will fit lenses with a focus barrel that measures between 70mm to 73mm in diameter, based on a compression value of -1mm when the rubber insert is fully compressed to fit.  For example, if your lens barrel measures 71.2mm, you would select and install the 71mm insert.  If required, please use the supplied shimming tape to fine tune the fitment.

Each kit comes with the following:

1 x Mod 0.8 aluminum follow focus gear / 10mm width (Optional 20mm width)

4 x Compressible insert (70mm, 71mm, 72mm, 73mm)

1 x Shimming Tape

1:  Using a caliper or measuring tape, measure the diameter of your focus ring.

2:  Once you have determined the diameter of your focus ring, select the insert that is closest to your diameter.  For example, if your lens barrel measures 75.2mm, you would select and install the 75mm insert.  Install the insert into the precision channels in the aluminum gear.

3:  VERY IMPORTANT.  Set your focus to infinity on the lens.  Failure to set your focus to infinity can result in damage to your helicoid.

4:  With your lens sitting upright and focus set to infinity, install the focus gear from the top-down, pushing gently and evenly until it comes to rest at your desired spot on the focus ring.  If installing from the top-down is not possible, you can install from the bottom, however, it is very important to set your focus to infinity before putting any upward pressure.
