Built to withstand the demands of professional use, this filter is both durable and lightweight, making it an indispensable tool for those who demand the best in optical performance.

### **Pros and Cons of the URTH Und4pl77 77mm ND4 Nano Lens Filter (Ultra Rim)**

1. **Compact and Lightweight Design** The "Nano" build is significantly smaller and lighter than traditional screw-in filters, making it ideal for travel and street photography. It attaches directly to the lens without requiring a filter holder, reducing bulk.

2. **High-Quality Optical Performance** URTH is known for producing neutral-density (ND) filters with minimal color cast and distortion. The ND4 (4-stop) filter provides consistent neutral gray density, allowing for smooth aperture adjustments in bright conditions without altering color balance.

3. **Ultra-Thin Rim** The "Ultra Rim" variant is even slimmer than standard Nano filters, reducing the risk of vignetting (darkening at the edges) and improving compatibility with wide-angle lenses. This is particularly useful for landscape and architectural photography.

4. **Durable Construction** Made from high-quality glass with a scratch-resistant coating, the filter is built to withstand frequent use. The metal frame ensures stability when attached to the lens.

- Slowing down shutter speed in bright daylight (e.g., for long exposures in landscapes).

- Creating a shallow depth of field in bright conditions without increasing ISO or opening the aperture excessively.

- Stabilizing video footage by allowing slower shutter speeds.

6. **Easy to Attach/Remove** The Nano design eliminates the need for a filter holder, making it quick to swap in and out of your lens bag. It attaches via a standard 77mm lens thread, ensuring compatibility with most DSLR and mirrorless cameras.

7. **Affordable Compared to High-End Alternatives** While not the cheapest filter on the market, it offers a good balance between cost and performance, especially for photographers who prioritize portability.

1. **Limited Stop Strength** An ND4 filter only provides 4 stops of neutral density, which may be insufficient for extremely bright conditions (e.g., midday sun on snow or water). Photographers shooting in such scenarios might need a stronger ND filter (e.g., ND8 or ND16) or a variable ND filter.

2. **No Variable Density** Unlike variable ND filters, this is a fixed ND4. If you need different levels of darkness (e.g., 2 stops for some shots and 4 for others), you ll need to carry multiple filters or rely on post-processing.

3. **Potential for Vignetting** While the "Ultra Rim" design minimizes vignetting, some wide-angle lenses may still experience slight edge darkening, especially if the filter isn t perfectly centered. This can be corrected in post-processing but adds an extra step.

4. **Compatibility Issues with Some Lenses** Although the 77mm size is common, lenses with very wide angles (e.g., ultra-wide fisheye lenses) or unusual thread sizes may still struggle with vignetting or fit. Always check compatibility before purchasing.

5. **No UV Protection** This filter is purely an ND filter and does not block UV rays. If you re shooting in environments with haze or dust (e.g., deserts, beaches), a UV filter might still be beneficial.

6. **Durability Concerns with Frequent Use** While URTH filters are generally durable, the Nano design lacks the physical protection of a screw-in filter. Dropping the lens could potentially damage the filter, though the metal frame helps mitigate this.

7. **No Built-in Polarizer** If you also need polarization effects (e.g., reducing glare on water), you ll need to carry a separate polarizing filter or use a variable ND-polarizer combo.

---

The **URTH Und4pl77 77mm ND4 Nano Lens Filter (Ultra Rim)** is an excellent choice for photographers who prioritize **portability, lightweight design, and high optical quality** without sacrificing too much performance. It excels in scenarios where you need to slow down your shutter speed in bright conditions such as landscapes, long exposures, or video work while keeping your gear minimal.

However, if you frequently shoot in **extremely bright conditions** or require **variable density**, you may need to supplement this filter with others. Additionally, photographers using **ultra-wide-angle lenses** should test for vignetting before committing.

For **travel photographers, street shooters, or videographers** who want a reliable, compact ND filter, this is a strong recommendation. For **landscape photographers** who need stronger ND filters or polarizers, pairing it with additional filters might be necessary.

- **Buy it if:** You want a lightweight, high-quality ND4 filter for general use, especially for travel, street photography, or video where bulk is a concern. The Ultra Rim version is ideal if you shoot wide-angle lenses.

- **Consider alternatives if:** You need variable density (e.g., a variable ND filter), stronger ND stops (ND8 ), or additional protection (e.g., UV/polarizer). In that case, a **screw-in ND filter** or a **variable ND-polarizer combo** might be more versatile.

- **Best for:** Photographers who value **portability over versatility** and want a reliable ND filter without the bulk of traditional holders.

Overall, the URTH Und4pl77 is a well-made, practical filter that delivers solid performance for its intended use.
