Curious about one thing: what's ur actual budget for the whole kit? Like, under $60 or u willing to spend more? In my experience, u don't need to overpay for the big brands tbh. * Neewer Universal 37mm Phone Lens Filter Clip ($12) fits the large OP15 island without vignetting.
* K&F Concept 37mm Variable ND Filter ND2-ND400 ($25) handles the Hasselblad color science well. Let me know ur price range!

sooo, i just got my OnePlus 15 too and i totally get the excitement but also the worry about that massive camera bump... its huge lol. basically, if u wanna do those smooth water shots, u need ND filters which are like sunglasses for ur lens. they let u use long shutter speeds during the day without everything turning white. but u gotta be super careful cuz the ultrawide lens on this thing is so wide that a lot of cheap clips will actually show up in the corners of ur photo which is basically a nightmare. For your situation, i really think u should look into a dedicated case system instead of a generic clip. i’m still a bit of a beginner with mobile photography gear, but i found that using something like the OnePlus+15&linkCode=osi&------123456890?5422-20" target="_blank" rel="nofollow sponsored">Moment Case for OnePlus 15 paired with the Moment 67mm Lens Filter Mount is the safest way to go. it makes sure everything is lined up perfectly so u dont scratch that expensive Hasselblad glass. then u can just screw on a high-quality filter like the Moment 67mm Variable ND Filter (2-5 Stop) and u are good to go! also, for the long exposures at night, i would suggest being really conservative with ur tripod choice. cheap ones might blow over in the wind and u definitely dont want ur new phone hitting the rocks. i’ve been using the Joby GorillaPod 5K Kit with Ballhead cuz its super sturdy but u can still wrap it around a tree branch or a fence. honestly its better to spend a bit more on stabilization than to risk the phone falling... anyway hope that helps and gl on ur trip!! 👍

For your situation, safety is basically key since that camera island is so big. I wouldnt trust cheap clips. Try the Kase Smartphone Master Filter Holder and Kase Wolverine Magnetic ND Filter Set 67mm—it feels way more secure on the OP15. Also for long shots I use the Manfrotto PIXI Mini Tripod. Its around $25, super stable, and wont let your phone fall over in a breeze lol. Hope it helps!!

I totally agree with Aaron about the alignment issues on these huge sensors. Its a nightmare if a clip isnt perfectly centered over the lens. I have been really satisfied with a more DIY budget approach that doesnt involve those expensive proprietary cases or mounts.

• SmallRig Universal Mobile Phone Cage 2791B
• This is my favorite find. It fits the OP15 perfectly even with a thin case and you can screw in standard accessories anywhere. Its way cheaper than the name brand rigs.
• Ulanzi MT-11 Flexible Octopus Tripod
• Honestly works better than my old fixed tripods for weird angles on rocks. No complaints about the stability for long exposures.
• Zomei 37mm Variable ND2-ND400 Filter
• I found this for a great price and it works well without messing with the Hasselblad colors too much. Since you are heading out for landscapes, just grabbing a universal cage like that SmallRig one gives you way more grip than holding the phone bare. It makes the whole setup feel like a real camera... really helps when you are trying to line up those wide shots. Dont be afraid to mix and match parts from different brands to save some cash. Happy to see more people pushing this camera system.

Quick reply while I have a sec. I'd definitely be careful about overspending on those high-end filter sets right away. You might want to consider the Zomei 37mm Adjustable ND Filter since it's super cheap and basically does the same job as the pricey ones for a fraction of the cost. I've had mine for ages and it's held up great. For mounting, check out the Ulanzi ST-27 Metal Phone Tripod Mount—it's heavy-duty and should handle the weight of the OP15 without slipping. I actually started using that same mount for my kid's school plays because it's so easy to swap onto a tripod. It's funny how these gadgets end up being used for totally random stuff once you have them. I think I use it more for recording soccer games and FaceTime calls with my family now than for actual professional-grade photography haha. But yeah, definitely keep it budget-friendly and save that money for some good food or gas on your trip.

TL;DR: Skip the basic clips and look into a modular DIY cage setup to avoid vignetting and sensor interference. Basically, because the OP15 has such a massive sensor array, I think the biggest hurdle is the optical axis alignment. IIRC, some folks on the developer forums mentioned that the ultrawide is SO wide that even the thinnest universal mounts might creep into the frame. If you're handy, I'd honestly suggest building a custom rig using a universal smartphone cage. Not sure if it’s common knowledge yet, but you can sometimes modify standard step-up rings to sit closer to the camera glass by removing some of the internal threads, which realy helps minimize light leak and vignetting. I haven't tested it myself yet, but I heard that the laser autofocus sensor on this model is realy sensitive to hardware being too close to the lens housing. You might have to DIY some spacers or use a specific offset to keep the Hasselblad tech working perfectly during long exposures. Going the "self-service" route with a modular cage gives you WAY better grip and stability than a flimsy clip anyway. Just my two cents!
