Fotodiox step-up rings are made of premium grade aluminum with precision. Every ring is inspected to ensure smooth mounting. Every ring is polished and finished with anodized matte surface for professional appearance. This step up adapter ring allows a filter/attachment with thread size of 46mm to be used with a lens with thread size of 37mm.
Fotodiox is easily a brand name that I,( a 20 yr veteran ), will turn to, understanding that every company (almost), has inexpensive, and HD accessories . Know the difference, I hate, reviews of $10,$20, etc items that would otherwise be $80+~$200 in a Brand brand name, that bash it's 'build quality's, THEN END WITH, You get what you pay for. You DO , rate it accordingly , but like in this case understand what you are reviewing. Threading 'Step up / down', rings is a precise machine process. Add coating and I've literally bought ones that don't fit, either to small or too big, either way I have no time to play. I can't grab my filters and be on a shoot NOT being able to size them or have the threads stick upon removal. Even though i try and condition every screw in part I ever use, there is always days when I'm grabbing the overnight from my delivery guy, and flying off to a shoot. Fotodiox is 1, of maybe 4 companies total, that I can do that with, & never get jammed up.
I needed a circular polarizer and i couldn't remember what size my lens was. So I check my other filters. Easy peasy no problem. My circular polarizer comes in and it doesn't fit, it's too big. Very confused, i convinced myself that the incorrect size filter must have been put into the box. I am one breath away from a call to the manufacturer (a name we all know) and I think, let me check my filters again. Sure enough, the filter box i checked happened to be my Infrared Filter and I had mistaken the IR rating (R72) for the filter size (67) and had ordered based off of that. SMDH. Thankfully many photographers great and small that came before me, have also made this mistake because the step rings have been a well established part of photography equipment for decades. Ordered this one, it fits both sides, it works great and now my forehead isn't red anymore.
This ring appears to be well-made; the inner and outer threads are smooth and non-binding, and it does not feel flimsy.
The Panasonic LX7 has a 37MM mount. As it turns out it is a proprietary mount. This adapter does not work for the Panasonic LX7. Though it does appear to by of good design and workmanship.
I have a 67mm thread lens and don’t want to invest another hundreds dollar for 67mm filters, with three 72mm filters on hand, this step ring is perfect for me. It fits perfectly on the 67mm lens, and on the other end the 72mm filter fits perfectly as well. But there is one issue, the lens hood won’t fit when the step ring is mounted. This is not a big deal since you don’t need lens hood for every situation.
Fits perfect. Screws on and off both my 77mm lenses smoothly. My 86mm filter has coarser threads and it also goes on and off smoothly. About all you can ask for, right? Much cheaper than buying several filters. If you are concerned about your lens hood not working with a bigger filter, and you believe you need one for a particular situation, buy a screw-on hood to fit the larger filter, or do like I do and use your hand or newspaper or anything handy to block the sun from getting in the front of the lens. That has worked for me for years. Good filters aren't cheap, and the fewer you have to buy the better. Step-up rings will save you a lot of money if you have just a few different size lenses.
I am updating and upgrading my smaller lenses to have 58mm filter mounts so that I only need one set of filters and common lens caps to make it cheaper and easier to outfit my multiple cameras and dozens of lenses. These are high quality step-up rings, well manufactured and professionally painted and finished. The threads are clean and clear and fit well to my lenses as well as my filters. Very good value for my needs.
So I had these 14 year old Sony lens laying around from my old Sony DCR-TRV900 camcorder, the lenses are the Sony VCL1452H Telephoto Conversion Lens & the Sony VCLR0752H High Resolution Wide Angle Lens.
I hired the PL100-400mm for an airshow, though needed an ND filter to fit it. Since I intend to eventually buy the lens, I bought the filter, but didn't want it to go to waste. So I picked up this step-up ring so that I could still utilise it with the shooter PL50-200mm.
Stupidly I left it a couple of months before testing the Fotodiox step up ring. It attaches ok at the back but the filter I was using would only slightly screw onto the front, despite this the filter is now stuck and won't come off. So I can't give this item a positive review.
I bought this so that I could use my 77mm 10-stop filters on my sony nex when I don't feel like carrying around a nikon d700 with a 24-70 lens. I have a 52-77mm step down (or is it step-up?) adapter which my filters go on, and then I attach those to this 49-55mm adaptor and screw that on to my NEX.
.... Saved me several 100 GBP on having to replace my 100mm lee filters system and filters with the sve5n system.
Screws on perfectly without issues, great metal quality. Filters and lens fits good.
Having purchased a Panasonic Lumix FZ100 Camera I found I needed a wider angle Lens for Survey work, the ones advertised for the 52mm thread of the Camera produced a high Vinyetteng at the corners,so by using a 58mm W/A & the 52-58mm step ring this was almost eliminated. Delivery was as always with Amazon brilliant & at a price no one else could match.
Useful items to have to use filters on multiple lenses. Buy for the largest lens and work backwards.
43 to 58mm step down ring is made from metal so thin it was already warped out of shape at time of delivery. What was manufacturer thinking. Completely useless. I’ll try Kood next time.
Its a ring adaptor.
I needed a step up ring to mount a 58mm wide angle lens to a consumer grade camcorder.
Ordered this 6 days ago from the US and it arrived today,Excellent quality item and i much prefer
Perfect to adapt my 58mm Gobe NDX filter to my smaller lenses, quality is very good
it s ok
M 39 thread was undersize and therefore a very slack fit into all  of my lenses
fantastic works well
