- The clipping pressure of a clip-on mattebox can make the focus ring of Super Speed lenses stiff; ARRI solutions for 15-mm lightweight rods (BPA-6, CBP-5/6) are bulky and tall, and CBP requires an additional dovetail plate.
- A 15-mm rod support mounted from above using an LMB 4x5 with a 143-mm clamp adapter works on all LMBs; an R2 ring from the MB-19 with a reducer from 114 to 80 mm keeps the rod support optically centered equally whether mounted above or below.
- The lower half of the BPA-6 is removable and saves height; an LMS-4 top plate mounted under the camera paired with UAP-3 plus LWS-6 yields the flattest base plate with centered rods, though this loses the rear attachment point.
- Third-party solutions include the Octamas ALEXA 35 Bottom Plate with integrated 15-mm lightweight rods and ARRI dovetail clamp (approximately 262 g), described as the lightest and flattest option; Catgriller dovetail fits directly into the top stage with 15-mm rods front and rear (19-mm adapter available); Wooden Camera ARCA plate and cam-jam rail plate kit are further alternatives.
- Some operators report that most MKIII Super Speed lenses tolerate a clip-on mattebox if focus is calibrated first and the clamp is tightened to only about 75 percent.
- Minimal solution: threaded filters or an 80-mm Series-9 filter holder with rubber lens shade.

- Whether clip-on matteboxes actually impede focus on Super Speed lenses is contested among operators.
- Solutions depend on the specific Super Speed lens generation and focus calibration.
- Height savings versus functional features (rear attachment, stability) involve trade-offs.
