On the X5s gimbal, I have read a bunck of great material and used it to  refine my operations. Some postings looked at rings, I am looking at  balance and filters, and how the X5s behaved...

My "partner" on this journey has been a 1000gm (0.1 uncrement) Jewler's scale...

DJI (Leica) OEM 15mm 1.7 (115gm)... I typically use a B+W XS-Pro 46mm UV  as a protector. I leave the 10gm DJI Brass BR10 46mm Balancing ring  off. The Filter is 13.4gm. I use the hood and DJI sleeve (1.5gm) . The  gimbal performs amoothly and without chatter or alerts.

Lumix 14-42 PZ Power zoom (extends during use), 93gm. DJI recommends  BR17 and BR6 which weigh 16 and 5.7 gm respectively. I use a B+W XS-Pro  UV 37mm brass, which weighs 10.4gm. I tried it with the 6gm weight for  17.3gm, and it wasn't happy (smooth and alert). I swapped the 6gm for  the 17gm plus the filter (26.6gm), the gimbal was happy and worked  perfectly. No hood needed with this lens. Of note is the fact that I  mount the filter after the BR17, adding to COB shift, saw no vignetting.  Handwheel2 for ZOOM makes it perform beautifully, great for golf  courses. From min focus to 30 feet Handwheel for focus is a BIG  improvement ofer my digits sliding and tapping.

Olympus 12mm 2.0, high quality lens (130gm),  Interesting balance due to  the short but heavy aluminium body. I used a B+W 46 XS-Pro UV (13.4gm  as above). no 10gm BR10, got an alert, but smooth. I swapped it for a  COKIN Harmonie 46mm UV (3.9gm), no hood (too heavy- weighs 14.3gm), and  although 5.4 gm lighter, works great, smooth, no alerts. Added an old  filter body as a hood, Tiffen 46 aluminium (no glass), perfect, cut  flare... Short focus throw on this means calibrated Handwheel helps a  lot.

Olympus 45mm 1.8, comes with Face ring (2gm), Hood (OEM) 10gm. Balancing  ring is set BR8 and BR6, total 14gm. I use a B+W XS-Pro UV (10.4gm),  was ok, but not smooth. BR6 was too heavy, with filter. Took an obsolete  Tiffen 37mm FLD, removed the glass, 3.8 gm. Used it after the filter,  like a hood, perfect. Smooth, cut flare... Going to try a cokin 37mm  Harmonie (s/b ~3gm).

Hope this helps

Thank you, this certainly helps.

Thanks for your input.
