This LEE Filters SW150 Mark II Lens Adapter is designed to allow a separately available SW150 Mark II Filter Holder to connect to a Tamron SP 15-30mm f/2.8 Di VC USD lens, which then permits the use of 150mm-wide, 2mm-thick filters without vignetting.

This lens adapter consists of three components: a front ring, a compression ring, and a locking ring. Placement of the lens adapter onto the lens is easily accomplished by sliding the front ring over the built-in hood with the front ring's integrated lugs positioned away from the lens body. The compression ring can then be slid over the rear of the lens until it meets the front ring. Finally, the locking ring is also slid over the rear of the lens until it can be screwed into the front ring. After that is accomplished, an SW150 Mark II Holder can be placed over the adapter from the front of the lens for use.

Q: 4. I'm wondering it this adapter will work with an earlier Lee Foundation Kit (FK) holder for 4x4/4x6 filters?

A: No, this is only for the SW150 Mark II holder.

Q: 5. Will a rear mount filter system like the one on this lens work with gradient gel filters (if those even come in a gel equivalent)?

A: In all our years of cinematography we have not heard of a rear gel grad filter ever being available. It is our opinion that it would not be practical. In order to fully utilizes grad filters, the user needs to position them precisely. That position may be higher or lower than the center of the frame. Also, it could be at an angle as well. This would be very difficult to manage in a rear gel. The clear solution is using 100mm filters in a holder such as NiSi S5 150mm Filter Holder Kit with Circular Polarizer for Select Tamron 15-30mm Lenses BH NIFH150T1530.
