Does anyone know which ND filters actually work well with the Sigma 18-50mm f2.8? I am super new to this and I feel like a total idiot even asking but I just got this lens for my Sony camera and I want to take those cool blurry water photos while I'm on vacation in Iceland next month. I keep seeing things about 55mm thread sizes and then people talking about 2-stop or 6-stop filters and honestly my brain is melting.
I checked Amazon and there are like a million brands like K&F and Tiffen and some are $20 and some are $200 and I have no clue if the cheap ones are just gonna ruin my photos. I spent most of my savings on the lens itself so I probably only have like 60 or 70 bucks left for a filter but I dont want it to look terrible. Is a variable one better for a beginner? I heard they can make a weird X shape on the image and that sounds bad. I just want something that screws on easily and lets me take photos of waterfalls without them being totally blown out and white. Does the brand matter that much for someone who is just starting out or should I just get whatever has the most stars on Amazon...

I remember being in your shoes when I first took my kit to some waterfalls in Oregon. I bought a cheap filter and every photo had a gross green tint... totally ruined the vibe. For your budget, here is what I have actually tested:
- K&F Concept 55mm Nano-X Variable ND2-ND32 is super convenient. You just twist it to darken the image. I noticed a little sharpness loss at the edges, but it is great for beginners. Just dont turn it past the marks or you get that X shape.
- Tiffen 55mm ND 1.2 Filter is a fixed 4-stop. Since it doesnt rotate, you get zero X-pattern issues and the colors are usually more accurate. The downside is it is less flexible if the light changes. Honestly, for Iceland, I would grab the K&F. Swapping filters in that wind and mist is a pain, so having one that does it all is way easier.

Like someone mentioned, variables can be tricky. I once used a budget one and it felt so gritty when turning... i was terrified it would scratch something. I actually disagree that a variable is best for beginners. A fixed one is much safer and simpler for a trip like Iceland.
- Hoya 55mm PROND64 Filter
- This 6-stop is a decent option for daytime waterfalls.
- It costs about 50 bucks and fits the Sigma perfectly.

Unfortunately, variables are usually not as good as expected when you're on a budget. I had issues with a cheap one where the color shift was just pathetic... totally ruined my trip. Like someone mentioned, the X-pattern is a real risk for those wide shots. Try these instead:
- Urth 55mm ND64 (6 Stop) Filter Plus+
- Hoya 55mm PROND EX 64 Filter A fixed 6-stop is much safer for waterfalls.
