Hi... I use the Panasonic 14-42 PZ for high quality golf course shoots. The optics are very good, and the power zoom works well with the handwheel2 for smooth slow precise zooming. Works fine with iPad mini as well.... I use a B+W MRC xspro UV in 37mm, with the br-6 ring and a glassless Tiffen ring as a hood. This is in Florida sun. The DJI br 6+17 rings weigh 23 gm. The setup I use weighs 21 gm. This lens chatters a bit at less than 18 gm. It is fine with the 17 gm br17 and the B+W filter at 26 gm. Hope this helps... BTW, I own the high quality Olympus 12 & 45mm primes as well, but the Panasonic performance is excellent on 4K and 5.2K....
