Review TIFFEN New 37 To 49mm Step up Black Ring 37mm

The Tiffen 3749SUR 37mm Step-Up Ring is a precision-engineered accessory designed to bridge the gap between lenses of varying flange focal distances, making it an indispensable tool for photographers seeking versatility and flexibility in their gear setup. Crafted from high-quality metal, this step-up ring is built to withstand the demands of professional use, ensuring durability and reliability across a wide range of shooting conditions. With a diameter of 37mm, it is perfectly suited for mounting on standard screw-in filters, polarizers, or other circular accessories, while its internal threading allows it to seamlessly attach to lenses with a 49mm filter thread commonly found on many mid-range and professional-grade lenses. This compatibility eliminates the need for costly lens adapters or compromises in image quality, as the ring maintains optical integrity without introducing vignetting or distortion. The smooth, precise threading ensures a secure and consistent fit, reducing the risk of accidental detachment during transport or use. Whether you're a landscape photographer looking to add a polarizer to a lens that doesn t natively support it, a videographer expanding your creative toolkit, or a studio professional managing a diverse collection of equipment, the Tiffen 3749SUR offers a simple yet effective solution. Its universal design makes it a practical addition to any photographer s toolkit, enabling seamless transitions between different lenses and accessories without sacrificing performance or ease of use.

The Tiffen 3749SUR 37/49mm step-up ring is a useful accessory for photographers transitioning between lenses with different filter thread sizes, specifically from 37mm to 49mm. Below is a detailed breakdown of its pros and cons, followed by a conclusion and recommendation.

### **Pros of the Tiffen 3749SUR 37/49mm Step-Up Ring**

1. **Compatibility with Multiple Lens Sizes**

The step-up ring allows you to attach 37mm filters (such as polarizers, ND filters, or graduated ND filters) to lenses with a 49mm filter thread. This is particularly useful if you own lenses with different filter thread sizes or if you frequently switch between them. It bridges the gap without requiring additional adapters for each filter.

2. **Cost-Effective Solution**

Purchasing a step-up ring is often cheaper than buying a full set of filters in both sizes. If you already own 37mm filters, this ring lets you reuse them on larger lenses instead of investing in new 49mm filters.

3. **Lightweight and Compact**

Step-up rings are lightweight and take up minimal space in your camera bag. They don t add bulk to your setup, making them convenient for travel or on-the-go photography.

4. **Versatility for Different Filters**

Since the ring accommodates 37mm filters, you can use a wide range of Tiffen filters (e.g., polarizers, color correction, or gradient ND filters) on lenses that would otherwise not fit them. This flexibility can enhance your creative options without additional hardware.

5. **No Loss of Image Quality**

Unlike some third-party adapters, Tiffen products are generally well-crafted and designed to maintain image sharpness and optical performance. The ring is made from durable materials and is engineered to minimize vignetting or distortion.

6. **Easy to Install and Remove**

The design is straightforward simply screw the ring onto the lens and then attach your 37mm filter. No tools are required, and it can be quickly removed when not in use.

7. **Compatible with Popular Lens Brands**

The 49mm filter thread is common on many lenses from Canon, Nikon, Sony, and other brands. If you own lenses with this thread size, the step-up ring will work seamlessly with them.

### **Cons of the Tiffen 3749SUR 37/49mm Step-Up Ring**

1. **Limited to 37mm Filters Only**

The ring only works with 37mm filters, not larger or smaller sizes. If you need to use 43mm, 52mm, or other filter sizes, you ll require additional adapters or rings. This can become cumbersome if you work with a variety of filter sizes.

2. **Potential for Vignetting**

While high-quality rings like the Tiffen 3749SUR minimize vignetting, some users may still notice slight darkening at the edges of the frame, especially with wide-angle lenses. This is more noticeable with certain filter types (e.g., large ND filters) and may require testing to confirm.

3. **Not Universal for All Lenses**

Some lenses, particularly those with very wide apertures or specialized mounts, may not accommodate step-up rings perfectly. In rare cases, the ring could interfere with the lens s autofocus or aperture mechanism, though this is uncommon with reputable brands like Tiffen.

4. **Additional Hardware Needed for Other Sizes**

If you later need to use filters larger than 37mm (e.g., 52mm), you ll have to purchase additional step-up or step-down rings. This can add to the overall cost over time if your filter needs evolve.

5. **Potential for Misalignment**

If the ring is not properly seated or if the filter is not centered, it could lead to misalignment or uneven light transmission. However, this is easily avoidable with careful handling.

6. **Not Ideal for Heavy Filters**

While the Tiffen ring is sturdy, very heavy filters (e.g., large ND filters) could potentially cause slight pressure on the lens mount if not securely attached. Most users won t encounter this issue, but it s worth noting for extreme cases.

### **Conclusion**

The Tiffen 3749SUR 37/49mm step-up ring is a practical and high-quality solution for photographers who need to use 37mm filters on lenses with a 49mm thread. Its advantages such as cost savings, versatility, and ease of use make it a valuable accessory for those who already own 37mm filters or want to avoid purchasing larger filter sets. However, its limitations, such as compatibility only with 37mm filters and potential vignetting, should be considered before purchase.

If you frequently switch between lenses with different filter threads or own a collection of 37mm filters, this ring is a worthwhile investment. For photographers who primarily use 49mm filters or plan to expand their filter sizes in the future, the long-term value may be lower, and other adapters might be more useful.

### **Recommendation**

- You own 37mm filters and need to use them on lenses with a 49mm thread.

- You frequently switch between lenses with different filter sizes and want a cost-effective way to reuse filters.

- You prioritize quality and durability in your photography accessories.

- You don t anticipate needing filters larger than 37mm in the near future.

- You primarily use 49mm filters and rarely need 37mm ones (in which case, purchasing 49mm filters directly may be simpler).

- You work with wide-angle lenses and are concerned about vignetting (test the ring with your specific setup first).

- You plan to expand your filter sizes significantly and may need multiple adapters in the future.

For most photographers who find themselves in the first scenario, the Tiffen 3749SUR is a solid, reliable choice that enhances flexibility without sacrificing quality. Pair it with high-quality 37mm filters (e.g., Tiffen ND or polarizers) for the best results.
