Arri Alexa internal filter module kit includes :

- IFM / Extenders depth gauge DG-1

- Internal filter tool

- IFM shim

- 0.0, 0.3, 0.6, 0.9, 1.2, 1.5, 1.8, 2.1, 2.4 Full spectrum ND Filters

- Filter cloth

- CD User manual

- Instruction manual

- Unlike standard external filters IFM filters have an anti-reflective multi-coating which maintains a high image contrast.

- The Alexa has an EI of 800 therefore ND filters are useful when shooting in bright conditions when a shallow depth of field is desired. 

- The FSND (Full spectrum neutral density) filters have an absorptive coating ensuring an even attenuation of the light over the full  spectrum therefore there is no color shift at any density.
