Review COMPUTAR Tv Zoom Lens 1.2/12.5-75

The **Computar 43320DN TV Zoom Lens** is a high-performance, professional-grade optical solution designed to deliver exceptional clarity and precision for television production, surveillance, and broadcast applications. Engineered with a **1.2/12.5-75mm focal length range**, this lens offers a versatile zoom ratio of **6:1**, allowing operators to seamlessly transition between wide-angle shots for expansive coverage and telephoto reach for detailed close-ups ideal for capturing everything from sweeping stadium views to intimate interviews. Its **fixed f/1.2 aperture** ensures maximum light transmission, reducing noise and enhancing image quality in low-light conditions, whether filming in dimly lit studios or under challenging outdoor environments. The lens features a **high-resolution, aspheric optical design** with multiple low-dispersion (LD) glass elements, minimizing chromatic aberrations and spherical distortion to produce razor-sharp, color-accurate images with minimal lens flare or ghosting, even at extreme zoom settings.

Built to withstand the demands of professional use, the **43320DN** incorporates a robust **metallic barrel construction** with a **heavy-duty iris mechanism**, ensuring smooth, consistent zooming and focusing without drift or backlash. The lens is equipped with a **standard 1-inch (C-mount) thread**, making it compatible with a wide range of cameras, including high-definition and 4K models, while its **manual focus and zoom controls** provide tactile precision for fine-tuned adjustments. For added convenience, the lens includes a **focus limiter switch**, allowing users to restrict the focus range to prevent accidental misfocusing during rapid transitions. The **weather-sealed design** further protects against dust, moisture, and temperature fluctuations, making it suitable for both studio and field applications, including outdoor broadcasts, live events, and security surveillance.

The **43320DN** excels in applications requiring both flexibility and performance, such as **news broadcasting, sports coverage, medical imaging, and industrial inspection**, where clarity and reliability are paramount. Its **low-light capability** and **wide aperture** make it particularly well-suited for documentary filmmaking and surveillance systems where ambient light is limited. The lens s **compact yet sturdy build** also makes it an excellent choice for handheld operations or mounting on stabilizers, drones, or robotic cameras without compromising image stability. Whether used in a high-end broadcast studio or a rugged field environment, the Computar 43320DN TV Zoom Lens delivers professional-grade optical performance, ensuring that every frame is captured with the precision and detail required for critical visual storytelling.

**Pros and Cons of buying a Canon 43320N (EF-S 18-135mm f/3.5-5.6 IS STM) Zoom Lens**

### **Pros**

1. **Versatile Focal Range** The 18-135mm range covers wide-angle to short telephoto, making it ideal for travel, landscapes, street photography, and casual portraits. This versatility reduces the need for multiple lenses.

2. **Image Stabilization (IS)** The built-in optical image stabilization helps reduce camera shake, allowing for sharper handheld shots in low light or slower shutter speeds. This is particularly useful for beginners or photographers who shoot in dynamic conditions.

3. **Lightweight and Compact** Compared to many other zoom lenses, this lens is relatively small and easy to carry, making it a practical choice for travel or everyday use. It s also compatible with Canon s APS-C DSLRs and mirrorless cameras (via adapter for some models).

4. **Autofocus Performance** The STM (Stepping Motor) autofocus system is smooth and quiet, which is beneficial for video recording and still photography. It also works well with Canon s Dual Pixel AF for autofocus tracking in live view.

5. **Affordable Price** This lens is one of the most budget-friendly high-quality zooms available, offering excellent value for its range and features. It s a great entry-level option for photographers looking to expand their kit without breaking the bank.

6. **Good Image Quality for the Price** While not as sharp as premium lenses, it delivers respectable sharpness and color accuracy for its price point, especially at wider apertures (f/3.5). Corner sharpness improves when stopped down to f/5.6 or higher.

7. **Weather-Sealed Body** The lens has a rubberized grip and weather-sealing, which helps protect it from dust and moisture, making it more durable for outdoor use.

8. **Compatibility with Canon s EOS R System** With an adapter, it can be used on Canon s full-frame mirrorless cameras (EOS R series), though performance may vary slightly due to the crop factor.

9. **Reliable Brand** Canon is known for its reliability, and this lens has a solid reputation for durability and consistent performance over time.

10. **Great for Beginners** Its ease of use, versatility, and affordability make it an excellent choice for new photographers learning the craft.

### **Cons**

1. **Fixed Aperture Range (f/3.5-5.6)** The aperture narrows as you zoom in, which can limit low-light performance and background bokeh effects. This is common for budget zooms but can be frustrating for creative control in certain situations.

2. **Not as Sharp as Premium Zooms** While sharp enough for most casual and beginner use, it doesn t match the edge-to-edge sharpness of higher-end lenses like the Canon EF-S 17-55mm f/2.8 IS USM or third-party options like Sigma or Tamron. Sharpness is best at mid-range focal lengths and wider apertures.

3. **Barrel and Pincushion Distortion** Like many zooms, this lens exhibits noticeable distortion at the wide (18mm) and telephoto (135mm) ends. While correctable in post-processing, it can be distracting in raw shots.

4. **Chromatic Aberrations** Some fringe colors (purple or green) may appear at the edges of the frame, especially at wide apertures or when shooting high-contrast scenes. This is manageable but can be annoying for detail-oriented photographers.

5. **Limited Low-Light Performance** The maximum aperture of f/3.5 at 18mm and f/5.6 at 135mm restricts performance in low-light conditions. You may need to use slower shutter speeds or higher ISO, which can introduce noise.

6. **No Image Stabilization for Full-Frame Cameras** While the IS works well on APS-C cameras, its effectiveness on full-frame cameras (when used with an adapter) is reduced due to the crop factor. Full-frame users may still need a tripod or faster shutter speeds.

7. **Plastic Construction** The lens body is primarily made of plastic, which, while lightweight, may feel less premium compared to metal-bodied lenses. However, it s still durable for everyday use.

8. **Vignetting** Some vignetting (darkening of corners) is noticeable at wide apertures, particularly at 18mm. This can be corrected in post-processing but may require adjustments.

9. **No Built-in Lens Hood** The lens doesn t come with a hood, which can be inconvenient for outdoor shooting where lens flare is a concern. A third-party hood can be purchased separately.

10. **Autofocus Speed at Telephoto** While the STM autofocus is smooth, it may struggle slightly at the longer end of the zoom (135mm) when tracking fast-moving subjects, though it s generally reliable for most casual use.

### **Conclusion and Recommendation**

The **Canon EF-S 18-135mm f/3.5-5.6 IS STM** is an excellent all-around zoom lens for beginners, travel photographers, and casual users who prioritize versatility and affordability. Its wide focal range, image stabilization, lightweight design, and smooth autofocus make it a practical choice for those who want a single lens to handle a variety of situations without investing in multiple primes or zooms.

- Serious photographers who prioritize edge-to-edge sharpness and low-light performance.

- Videographers who require consistent autofocus performance at the telephoto end or need wider apertures for shallow depth of field.

- Full-frame users who want to avoid adapters and may prefer a native full-frame zoom.

- Those who frequently shoot in extremely low light or need the flexibility of a fast aperture.

If you re a beginner or an enthusiast looking for a **versatile, affordable, and reliable zoom lens** for your Canon APS-C camera, the **EF-S 18-135mm f/3.5-5.6 IS STM** is an outstanding choice. It strikes a great balance between performance, portability, and cost, making it one of the best all-around lenses in its price range.

However, if you re a full-frame user or a more advanced photographer who prioritizes image quality and low-light performance, you might consider pairing this lens with a faster prime (e.g., a 50mm f/1.8) or investing in a higher-end zoom like the **Canon EF-S 17-55mm f/2.8 IS USM** or a third-party option like the **Sigma 18-35mm f/1.8 DC HSM** (if compatible with your camera).

For most casual and intermediate users, this lens will serve you well for years to come.
