Always buy the best quality you can.

Even the best filters impair quality, even if only slightly. The problem is flare and reflections off the sensor rather than sharpness. Stacking filters together doubles the problems.

What are you wanting to do with this filter? ND8 is only three stops, not 8, in case you were going to try long daylight exposure times.

I always try to buy the best, but couldn't reason why they were double the price!

Yes, you are right, I was planning to do some daylight, long exposures. Can you suggest something suitable if this is not the right filter for the job?


Edit> Looks as though I made a bit of a 'howler' with the ND8. I'm guessing I need something like a ND64 for a 6-8 stop filter?! :bonk:

I'm planning on taking some coastal/lake shots when I head down south in April, so I'm only really guessing what ND filter would be suitable. Glad I asked now!

Haha! Everybody makes that mistake. Filters are also marked in optical density, eg 0.3 is one stop, 0.6 is two stops etc.

Of course the amount of ND you need depends on the available light but for what I imagine you want to do most people go for a fairly massive ten stops, that's x1000 or 3.0.

Yep, classic mistake! Glad I asked otherwise I'd be £60 lighter! :cuckoo:

Thanks for the link - todays lesson - it pays to read! ;)
