Top recommended filters and adapters for Olympus OM-D system?

Question

Hey everyone! I’ve been shooting with the Olympus OM-D system for a few months now, and I’m absolutely loving how portable the setup is compared to my old DSLR. However, I’m looking to level up my landscape and architectural shots and realize I really need to invest in some quality filters and adapters to get the most out of the MFT sensor.

Right now, I’m specifically looking for a solid ND filter for long exposures and a high-quality CPL to cut down on reflections. Since many MFT lenses have relatively small thread sizes, I’m torn between buying individual screw-in filters for my 12-40mm Pro or biting the bullet and getting a square filter system. Has anyone had issues with vignetting when using filters on the wider glass, like the 7-14mm f/2.8?

Additionally, I have a drawer full of old vintage OM-mount and Canon FD lenses that I’d love to breathe new life into. I’ve seen everything from the budget-friendly $20 adapters to the high-end Metabones speed boosters, but I’m worried about light leaks or loose mounts affecting the image quality.

What are your "must-have" filters or adapters that have earned a permanent spot in your camera bag? I’d love to hear which brands you think offer the best build quality for the OM-D ecosystem!

tbh after years of shooting MFT, that Olympus M.Zuiko Digital ED 7-14mm f/2.8 PRO is still tricky. I'd suggest a square system like the NiSi V7 100mm Filter System Kit to avoid vignetting. For vintage glass, the Metabones Canon FD to Micro Four Thirds Speed Booster T Ultra 0.71x is GREAT, but maybe too pricey? I've used cheap Fotasy Canon FD to M4/3 Adapter ones forever and theyre pretty okay! gl!

Budget adapters leaked light for me, sooo bad! Since circular filters usually vignette, I recommend the Haida M10 Filter Holder Kit. It’s way more reliable for architecture. gl!

Saw this earlier but finally got a minute to weigh in. Honestly, i have had some real issues with the cheaper adapters that everyone seems to love. The fit was always slightly off for me and it basically ruined the experience of using my vintage glass because of the constant wobbling. It is super frustrating. If you want something that actually stays put, just look at whatever Novoflex makes for your mount. It is way more expensive but the build quality is actually reliable. For the glass, i was pretty disappointed with the results from those budget square systems. The color shift was a nightmare to fix in post. Just go with PolarPro or maybe Urth if you want something that feels solid. You really get what you pay for when it comes to the coating quality. Tbh, you should spend some time on the Mu-43 forums or look at the compatibility spreadsheets on DPReview. There are some great user-made guides there that go deep into which specific brand combinations tend to leak light. Saved me a lot of headache after i already wasted money on junk.
