Vivitar HD4 MC AF 0.43 Hi-Def WA Converter with Macro (58mm Thread Size)

Here are some key features and details about this wide-angle converter:

1. Focal Length Multiplier:

   • The 0.43x focal length multiplier indicates that this converter widens the angle of view, allowing you to capture more in the frame compared to the original lens.

2. Compatibility:

   • The converter is designed to fit lenses with a 58mm filter thread size. It's important to ensure compatibility with your specific lens before purchasing.

3. Wide-Angle Capability:

   • The primary function of the converter is to provide a wider perspective, making it useful for capturing landscapes, architecture, or group shots.

4. Macro Capability:

   • The "Macro" feature indicates that the converter can also be used for close-up photography, allowing you to focus on subjects at a very short distance.

5. Multi-Coated Optics:

   • The "MC" in the name stands for multi-coated optics. Multi-coating helps reduce lens flare, ghosting, and improves overall image contrast and clarity.

6. Attachment Method:

   • This converter typically screws onto the front of the existing lens, using the 58mm filter thread.

7. Construction:

   • The build quality may vary, but converters like this one often have a combination of metal and plastic components.

8. Image Quality:

   • While wide-angle converters can be convenient for expanding the versatility of your lens, it's important to note that the optical quality may not match that of a dedicated wide-angle lens. There can be some trade-offs in terms of image distortion and corner sharpness.

9. Compatibility with Autofocus:

   • The "AF" in the name suggests that it supports autofocus. However, the effectiveness of autofocus with such attachments can vary, and manual focus may be preferred in certain situations.
