Hi folks,

I was wondering if anyone could suggest a good step-up ring to use with the NX70? Ideally a 37mm-58mm model.

I got one of these: General Brand 37mm-58mm Step-Up Ring (Lens to Filter) 37-58 B&H


But the problem is, it won't fit the NX70, the connection isn't "deep" enough, and doesn't make contact with the thread on the front of the lens. It does fit if I stick it on the outside of my UC filter, but that's awkward and vignettes badly.

Can anyone recommend a specific brand and model? There are so many "generic brand" versions of this, and I don't want to have to buy them all to see what works. I would also prefer a UK or European supplier, I don't really want to buy a $10 adapter and add on $100 just to get it posted to me.

Thanks in advance.

It's funny, Mike.
I bought a "general brand" 37-52 (and then used a 52-77 so I could use my variable ND filter) and it worked without a problem with no cut-off at all. I guess their general brand might come from multiple suppliers or just have poor quality control.

I have also used both Bower and Tiffen rings with success

Thanks Chuck - I will maybe try one of those brands.

The "Generic" I got from B&H had a very, very shallow filter screw that just wouldn't reach the threads. I have another alternative on order, if that doesn't work out I'll try to source one of the brands you mentioned.

Chuck,

I think they key here is to do it in two steps. The second 37-58mm I ordered is exactly the same as the first.

Thinking about it again, it is logical. A 58mm filter is the same size as the front of the barrel of the NX70, so it's never going to fit unless you get a cone-shaped step-up ring, which is unlikely. That 52mm you have probably fits perfectly inside the NX70 lens area.

I'm going to go the two-adapter route, the first one stepping up to an intermediate size, the second to 58mm. The purpose of this is to get a better mounting with my Cavison mattebox.

I'll report back with my findings, including photographs!

Using the two step ring system worked for me for a couple of reasons. For one thing, I was less concerned about using a matte box, as the reason I was using this camera was to stay small and very compact. I wanted to use a 77mm variable ND, which I already owned and it allowed me to use a wide angle rubber shade that afforded both light protection and a bit of impact protection, as well.

By getting the biggest, thinnest filters you can afford you are also making the filter a bit future proof, as you will, at some point own another camera.
