When you shop camera lenses filters, the first decision is what kind of accessory actually solves your problem. Do you need more reach, a wider view, less glare, or slower shutter speeds? A conversion lens changes the focal length of your existing lens, a circular polarizer (CPL) cuts reflections and enriches colors, and a variable neutral density (ND) filter reduces light for long-exposure or shallow-depth-of-field work. The four options here range from $8.79 to $151.99, so your budget can stay small if you only need one effect.
Quick Take
- The EcostConnection 72mm CPL is the lowest-priced item in the set and focuses on reflection control and color improvement.
- The K&F CONCEPT ND2-ND400 variable ND offers light reduction across a wide range of filter sizes.
- The Acuvar 72mm conversion lens lets you choose between a 0.45x wide-angle or a 2x telephoto variant.
- The XIT/ULTIMAX ultra wide angle with macro is built around the Canon EF 28-300mm f/3.5-5.6L IS USM Lens and carries the highest listed price.

Decision Matrix

|---|---|---|---|---|
| Main job | Add wide-angle or telephoto reach | Ultra wide-angle plus macro for one Canon lens | Reduce reflections and improve color | Adjustable light reduction |
| Filter/lens type | Conversion lens | Auxiliary lens | Circular polarizer | Variable neutral density |
| Sizing | 72mm | Built around Canon EF 28-300mm f/3.5-5.6L IS USM Lens | 72mm | Multiple sizes from 37mm to 82mm |
| Price position | USD 28.99 | USD 151.99 | USD 8.79 | USD 21.11 |
If you're still deciding, start with the lowest-priced option that covers your most frequent subject. Add a converter or variable ND only when a second effect matters.
Product Notes
Acuvar 72mm Conversion Lens
Choose the Acuvar 72mm Camera Lens Filter when you want a conversion lens rather than a filter. The product comes in two versions: a 0.45x wide-angle and a 2x telephoto, so you can select the effect you need for DSLR or SLR shooting. It also includes a detachable macro element for close-up work with the wide-angle option. The main limitation is that you pick one variant, not both, so a single purchase won't cover both wide and telephoto situations. Also, the 72mm sizing means you'll need a lens with a matching thread to use it.
Ultra Wide Angle with Macro for Canon
The XIT/ULTIMAX ultra wide angle with macro is the only product here that names a specific camera lens in its title: the Canon EF 28-300mm f/3.5-5.6L IS USM. It pairs a fisheye-style wide view with a separate macro attachment, making it a two-in-one auxiliary lens for wide-framing shots like skateboarding, skydiving, or big group scenes. The limitation is the scope: if your lens doesn't belong to that Canon family, the title gives you no reason to expect it to fit. It also sits at the top of the listed-price range, so it's a bigger investment for a single-lens add-on.
EcostConnection 72mm CPL
EcostConnection's 72mm Circular Polarizer Filter is a straightforward pick for cutting glare and boosting color. The CPL frame rotates so you can tune how much polarized light passes through, and the product highlights reflections from glass, water, and shiny surfaces. It's the lowest-priced option here, but it does one job rather than several. It won't change focal length, reduce light for long exposures, or add a macro function. You'll need a lens with a 72mm filter thread, and the effect depends on how you use the rotating frame.
K&F CONCEPT Variable ND
The K&F CONCEPT ND2-ND400 Lens Filter is the variable neutral density choice for shooters who want adjustable light reduction in one accessory. The filter rotates through lighter and darker settings, and the available sizes cover 37/40.5/43/46/49/52/55/58/62/67/72/77/82mm, so it offers the broadest thread-size flexibility in this set. It won't reduce glare the way a CPL does, and high stops can produce a natural 'X black cross' effect with certain lenses. Choose it when you want shutter-speed control rather than reflection control.
Final Recommendation by Use Case
- For glare and saturated landscapes: choose the EcostConnection 72mm Circular Polarizer Filter.
- For long-exposure style shooting across multiple lens sizes: choose the K&F CONCEPT ND2-ND400 Variable Neutral Density Lens Filter.
- For flexible reach between wide and telephoto: choose the Acuvar 72mm Camera Lens Filter with the variant that matches your shooting.
- For Canon EF 28-300mm f/3.5-5.6L IS USM owners who want an ultra wide-angle and macro add-on: choose the XIT/ULTIMAX ultra wide angle with macro.
