(2 Pcs) 37-43MM Step-Up Ring Adapter, 37mm to 43mm Step Up Filter Ring, 37mm Male 43mm Female Stepping Up Ring for DSLR Camera Lens and 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!

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.

Perfect fit. Works great.Added to tameron lens and add UV light protection. This helped in adding canon ring flash.

Item is a good value with very competitive price and features. Works as described.

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 attachmentsThis 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.

This are great. Got these to fit ND and a CPL filter on a canon RF 50mm .Quality is solid easy to thread to the lens housing.

Got this ring adapter for my Canon M50 lens. Worked perfect! Very happy with the quality of the product. Worked perfectly for me.
