p.1 #1Sony RX1R III accessories - searching for magnetic UV filter, thumb grip and soft release button
Hello everyone.

I was wondering if anyone can suggest some accessories for the Rx1R III. Looking particularly for the following:

- good quality magnetic ring and filters - mostly protective one, but will also add more in future - is Breakthrough any good brand?
- thumb grip that does not obstruct all the wheels, yet doestn't cost $$$ like the sony?
- soft release button with "fat" thread that does not look crooked?

Please share your findings as it's pretty strange that there is not much out there that matches my list.

Thank you.

I've had the RX1r.3 for nearly a year. Here's what I'm using.

UV filter screwed directly on the lens: Kase MCUV III Ultra Slim UV Filter (49mm)
https://www.bhphotovideo.com/c/product/1848265-REG/kase_1102020006_mcuv_ii_ultra_slim.html
-Very good optical and build quality, it's a slim filter and doesn't protrude too far from the lens.

Magnetic filter set: Kase KW Revolution Mega Set (49mm)
https://www.bhphotovideo.com/c/product/1852276-REG/kase_1110112203_revolution_mega_set_49mm.html
+All the filters are magnetic and stackable, comes with magnetic rings that screw into the front of the lens
+Comes with 3 ND filters, a polarizer, a light pollution filter, and a UV filter (I use a standard screw-in UV)
+Comes with a magnetic lens cap, which is very handy
+Magnetics are VERY strong, never had a filter come off unintentionally
+Very good optical quality, haven't noticed any color cast or vignetting

Filter case: K&F Concept 3-Pocket Circular Filter Case (Up to 62mm)
https://www.bhphotovideo.com/c/product/1795046-REG/k_f_concept_kf13_139_3_pocket_circular_filter_case.html
+The included filter pouch that comes with the Kase system is comically huge and obnoxious

Flash: Godox iT30Pro S TTL Mini Flash for Sony (Black)
https://www.bhphotovideo.com/c/product/1895980-REG/godox_it30pro_s_black_it30pro_s_ttl_mini.html
+If you're looking for a compact TTL flash, I use and can recommend this one
+Size, weight, and appearance are a good match for the RX1 series
+Decent power and recycle times
+Also works as a remote trigger for other Godox flashes
-I'd recommend getting a diffuser, which doesn't come with the iT30Pro for some reason

Hand/thumb grip: IDSworks hand grip / thumb grip for Sony RX1RIII
https://idsworks.store/products/idsworks-hand-grip-thumb-grip-for-sony-rx1riii?variant=44208150052909
+Excellent fit and finish
+Improves the grip on the soap bar RX1 immeasurably
+Very light and low profile, barely makes the camera any taller
-Bottom of the plate does not have a tripod thread. I'm okay with this since I don't want the camera to be any taller
-Stupid money for what it is, but the quality is excellent

Small bag: Bellroy Lite Sling Mini (4 liter)
https://www.amazon.com/Bellroy-Lite-Sling-Mini-Ash/dp/B0CY9XNVFF?th=1
+Countless options for a small bag, but I've been happy with this one
