Essential lens filters for Sony 24-70mm GM II owners?

yo, honestly I've been using that lens for a year and finding the right glass is a struggle. For your situation, I would suggest being super careful with frame thickness because vignetting at 24mm is actually highkey annoying on the GM II. 1. B+W 82mm Master Clear MRC Nano 007M Protection Filter vs Hoya 82mm HD3 UV Filter: The B+W is built like a tank, but unfortunately, the brass ring keeps binding on my Sony's threads. The Hoya is thinner but it's a total pain to clean... wouldn't recommend it tbh.
2. PolarPro 82mm QuartzLine Circular Polarizer Filter: This is basically the winner for landscapes. It's way slimmer than the B+W alternatives so you dont get those dark corners at 24mm. Best choice? I'd go with the Breakthrough Photography 82mm X4 UV Filter for daily protection. The color neutrality is actually better than the bigger brands i've tested. Anyway, gl!

Honestly, im gonna go against the grain here and suggest a completely different approach. Everyone is focused on which glass to put in front of your GM II, but as someone who's shot Sony glass professionally for years, I'd argue the best way to protect that investment is actually a 'naked' lens with a rigorous DIY maintenance routine. Basically, even the highest-end UV filters introduce two extra air-to-glass surfaces which can lead to ghosting or internal reflections in harsh lighting. If youre chasing that peak GM II sharpness, adding more glass is counter-intuitive. Here is my DIY self-service protection kit instead: 1. Use the lens hood 24/7. It provides way more impact protection than a thin piece of glass ever will and prevents flare. 2. Invest in a Giottos Rocket Air Blaster and high-quality Zeiss Lens Cleaning Wipes. Learning to safely clean your front element yourself is a key skill. The fluorine coating on the GM II is incredibly durable and shed oils easily anyway.
3. For the CPL, if you really want to avoid vignetting and maintain that 'pro' workflow, look into the Kase Wolverine Magnetic Circular Polarizer. It's a magnetic system so you dont have to keep screwing things onto the brass threads, which avoids the binding issues others mentioned. Just my two cents, but definately think about whether you really need that UV filter or if it's just a security blanket. Keep it clean yourself and let that Sony glass breathe!

> I’ve had issues with vignetting at 24mm with thicker frames, so just go with PolarPro or Hoya and you cant go wrong. Totally agree that frame thickness is the silent killer on this lens... I learned that the hard way with an old variable ND I tried to reuse. If you want a solid middle ground between protection and quality for long-term use, here are my quick tips:

• Look into a magnetic system like the Freewell Magnetic UV Filter. It is way thinner than most screw-ons and makes swapping to a polarizer way less of a chore when youre in a rush.
• If you prefer the classic screw-ins, the Urth Plus+ UV Filter has been surprisingly solid for the price without messing with the GM II sharpness. I have been using the Freewell setup for a few months now and honestly havent noticed any major ghosting issues. Plus, you can stack the magnetic caps right on top which is super convenient for daily carry. Just keep that lens hood on for physical protection and you should be good to go, basically what more do you need???

Respectfully, I'd suggest a different approach than just the standard big names everyone mentions. I've been shooting with the GM II for a while now and I was super paranoid about ruining that sharpness, so I did some deep diving into the technical specs to avoid any vignetting at 24mm. While others suggested PolarPro, I actually found them a bit bulky for my taste. Here’s what I’ve been using instead: 1. NiSi 82mm HUC UV Filter: Honestly, this is the way to go if ur worried about frame thickness. It’s ultra-slim and the glass quality is incredible. I haven't seen a single hint of vignetting even at the widest focal length.
2. Marumi 82mm Exus Lens Protect Solid: I'm a pretty cautious guy with my gear, and this filter is basically a shield. It’s way stronger than your average protector but still maintains that highkey transparency you need for a GM lens.
3. NiSi 82mm True Color Pro Nano CPL: I’ve tried a few, but this one is the most color-neutral CPL I’ve ever owned. No weird yellow or blue casts which saves me so much time in post. I’m really satisfied with this setup... it works well and gives me total peace of mind without compromising the image quality. Hope that helps! 👍

For your situation, just a protector and a polarizer are the only essentials you need. I’ve had issues with vignetting at 24mm with thicker frames, so just go with PolarPro or Hoya and you cant go wrong. Honestly, I was pretty disappointed with how some other things performed on this glass. Just get the premium slim lines from those brands. Basically, don't skimp if you want that GM II sharpness to stay perfect...

I've been using the GM II for nearly a year now and I'm still super satisfied with how it handles. To keep that legendary sharpness without seeing dark corners at 24mm, you really have to be picky about the glass quality and the ring height. Like someone mentioned, the frame thickness is usually what ruins the shot at the wide end. Here are the two I've found that work perfectly:

• Kenko 82mm Zeta Quint Protector
• I use this for daily protection. It uses hardened glass that is way tougher than your average UV filter, but the frame is still incredibly low-profile. No vignetting at all.
• Haida 82mm NanoPro MC Circular Polarizer
• This is my go-to for landscapes. Honestly, the color neutrality is excellent and it doesn't give that weird yellow cast you sometimes see with cheaper polarizers. Basically, if you invest in the high-end lines like these, you wont regret it. The build quality matches the lens perfectly and I havent had any issues with the threads sticking or the image quality degrading. Just make sure you get the genuine versions since there are lots of fakes out there... it really makes a difference on a lens this good.
