[1 oz / 27 g] When time easy without any bubbles.

[1 oz / 27 g] This is an ingenious battery and USB charger. The charger is small enough to serve as a case for the battery.

[0.12 lb] This is an obvious extension for a camera I believe will be very dominant in the documentary filmmaking field. But it is equally clear that we need a good cage, good filters and maybe even extension battery recharging from a small accessory attached to the cage -- and yes, this filter accessory is ONLY the very beginning. Sturdy, well made and for me it will always be attached with the sun shade.

[0.12 lb] Easy to install. Low profile. good value for the money

[1 oz / 27 g] works great ! Does what it's suppose to !!!

[1 oz / 27 g] Does what it's supposed to do. I have two batteries, while one is in use, the other is charging. It also helps with making sure that the battery isn't lost because it doubles as a single battery case.

[0.12 lb] I’ve awarded this four stars, not because it is a brilliant piece of kit, but because it is essential if you want to control shutter speed, especially important for video.

Let’s take 4K recording (which requires an external recorder) as an example.

The camera is fixed f/4 and the minimum ISO for 4K, as with the RX100 V, is 1600. In bright sunlight, this will give an aperture of f/64 to f/90. If you shoot S-Log 2, which has the benefit that you can over-expose it by 1.5 - 2.5 stops, this still leaves the need for a neutral density filter reducing exposure by about six stops.

There are very few companies making 30.5mm neutral density filters. I purchased B+W filters (neutral density and a polarizer). These are expensive, but the alternative (a step-up ring plus a stepped up lens shield) proved very difficult to acquire. Heliopan offers this solution, but I spoke with them and they confirm B&H’s wait time of about six weeks.

The RX0 has no problem with vignetting with the B+W filters, including stacking two of them, but stacking does cause an issue with the lens hood, which may require application of a bit of gaffer tape when filters are stacked.

[0.12 lb] Very important protector. I have never used these protectors until a put a scratch on an lcd screen on my pocket camera. Now I will always have a lcd screen protector. They are very clear and you can the image very clearly.

[0.12 lb] I was nervous at first because Id never seen a charger like this one before, but it works great and is really easy to travel with.

[1 oz / 27 g] Yes so, this works and charges batterys.
It´s compact and works via USB.
No surprises, no complaints.
