(2 Pcs) Fotasy 37-40.5MM Step-Up Ring Adapter, 37mm to 40.5mm Step Up Filter Ring, 37mm Male 40.5mm Female Stepping Up Ring for DSLR Lens & ND UV CPL Infrared Filters

This 49-67mm step-up ring adapter is exactly what I needed to use my 67mm filters on a 49mm lens. The metal construction feels sturdy and high-quality, with smooth threading that attaches securely without any cross-threading or wobble. No light leaks, no vignetting — just a perfect, seamless fit. It’s a simple tool, but super effective and a great way to save money by using one set of filters across multiple lenses. Definitely a must-have for any photographer building out their kit!

They go on easy, no problems with vignetting or colors, very strong metal and have had no glare at all. Very slim too.

These adaptors work perfectly well, they have excellent finish, and they actually look better than what you can see in the product pictures.

These 58–82mm step-up rings are just what I needed to use my larger filters on smaller lenses. The threads are clean and smooth — they screw on easily without binding or sticking. The metal feels sturdy, not thin or cheap, and the finish matches my gear nicely. I’ve used them with ND and CPL filters, and everything fits tight with no light leaks. It’s a simple tool, but it does the job perfectly. Handy little adapters that save money by letting me use one set of filters across multiple lenses.

I ordered the 67-77 mm step-up adapters. Both adapters work. The built quality are OK. Have to carefully align the 67mm male thread (lens side) before turning. Once correctly aligned, the turning is smooth. The same apply to installing the 77mm attachments. At this price point, I cannot ask for more. The workmanship is decent and they offer great value for the money.

This is a Step converter adapter for any camera, or camcorder with a 37mm thread to fit some Vivitar telephoto lens. It bridges the gap between smaller threads to larger thread sized lens attachments This attachment is meant for certain Cannon digital cameras. Usually the lens size is marked with a O with a line through it. Alternatively you can get a millimeter ruler with slider bars to count all the lines. But I actually had to ask the manufacturers lol. What you see is an the side screen. When zoomed out or 1x at the lowest end, that fish eye crop shows up. If I zoom in a bit more, that interior view goes away. The camcorder has no optical zoom so this as the diameter size of the lens attachment was marked on the cap cover. But not marked on the Camcorder. Usually a circle with a line through it indicates the thread size. I will later order a manual zoom dial thing but the Vivitar gives you 2x zoom. It's a fixed or prime lens. Also among the cheapest. But when you increase the focal ranges, the image that is captured gets smaller. You loose the background sharpness but you zoom in on a subject or object. Basically the field of view narrows but gives you what is important. 50+ is mid range. But get below that, you get a wider field of view. And when to use attachments is for things out of its range. This particular camcorder is a Camworld AC13. With f/3.6mm to f=7.63mm . Those lower ranges is actually good for wide angle shots to give you both sharp background and good visuals of faces. And guessing that 40 feet 😂 with no optical zoom is where most camcorders get fuzzy, when you zoom out too far. But it's more about the type of scenery you intend to get. So a sports stadium lol is not going to be clear. You would need a higher focal lens. And you shouldn't expect a camcorder to pull in the faces of a sports player. You need the bigger things that film makers use, that are easily $3,500+ vs $80-$350s for camcorders. Camcorders aren't meant for professional grade filming. Now for Aperture that is on the lower end gives you good low light and not an over exposed picture. It might be labeled as 1:2:3. 1-5 which is basically the shutter, to regulate how much light comes in. What it all boils down to, when it comes to lens attachments: The lens attachment, needed depends on what your filming or taking shots of; and is more important than the device itself. This Camcorder has 4K resolution, 42MP camera and an full HD 3 inch display. The AC13. Made by Camworld. And, it's actually impressive for the price. It comes with an external mic, lens hood, stabilizer bar, two batteries, SD card, battery bay charger, a remote, and a USB C cable. Soon I will post my review on that. It's all USB C charging/powered. The AC13 connects via USB C to charge, or data (to any PC). The other mode is webcam. You can then use it to live stream, via a laptop with Internet access. For things like YouTube, Skype, Facebook and such. The mic is rechargeable. Standard 1/4in thread for tripod mount and it's got "hot shoe" connector. It's a port that slides in and tighten or loosen. To pull footage off- You either pop the memory card out or connect it via USB C to pull the footage. The mic of course should only be used for audio further away and not 3 feet away. As it will record and be barring. Though you can always lower the master volume.

The ring worked as it should. The quality is very good for the price, and you get two rings for what you would pay for one at other retailers. If you're careful not to cross-thread the ring when putting it onto your lens, it goes on and comes off very easily.

Love it, fit well

Actually I want Moment 67mm filter adapter or Moment 67mm filter adapter but I don’t get those things in market so I use 37mm 52mm step up filter adapter. So I need an adapter with 52mm to 67mm step up ring. Very nice, rugged but lightweight material product and very good thing is I get this product 7 days early.. proper 1 week early. I never expected this thing neither I get this experience before so I like the delving system. Thank you.

Económico y de buena calidad. Muy recomendable.

Solid construction and screws on easily. No fuss!

this is my 2nd set and I am returning them all. Out of 4 rings only 1 threads onto the lens and the filter. 1 other one threads on 1/2 way then binds. My lenses are thousands of dollars and my filters hundreds, so messing around trying to get one of these to thread on without slipping and scratching some glass is just not worth it. Wast of money in my opinion, don't waste yours. I shouldn't have cheeped out, but its not rocket science, its just threads on a ring. Bought for 70-200mm Canon and

Produto excelente, rosca de encaixe bem justo.
