Sen ei Aluminum Step-Up Ring Reviews

Excellent quality for a low price.

I have step-up rings from at least 5 different brands and the Sensei ones are just as well made as the more expensive ones. The only difference is if they are made of brass which makes them easier to remove if you need to exchange them often.

I always buy Sensei…

I always buy the Sensei Step-Up Ring when I need one. For the price, it is good quality, thin and does the job. B&H Photo has great customer service, they always ship my orders fast.

No, that step-up ring will not fit. The Sirui 60mm Portrait Lens does not have threads to screw into.

Can I stack two filters?
Asked by: Gustavo
Yes, you can stack 2 filters with the same size thread but beware of vignetting (darkening of the edges) with wider angle lenses.

Are both threads fine/standard or is the 95mm coarse like the Canon RF 28-70L and the 67mm fine?
Asked by: Nick
The Sensei 67-95mm Aluminum Step-Up Ring has course 1.0 pitch threading on the 95mm side, and standard 0.75 pitch on the 67mm side. This is fairly standard for these sizes.

If I have a camera with a 30mm lens, and a 37mm fisheye, do I need a step up or step down ring?
Asked by: Charlie
If your filter/attachment is larger than your lens, it's a step-up. In this case, your fisheye attachment is 37mm and your lens' front diameter is 30mm, hence, you'd need a step-up ring.
