It is a very professionally made piece of equipment. There was an issue with the billing but it was resolved quickly and accurately. The thread on the Lens is a 42.5 x .7 which is kind of an odd ball. We needed a polarizing filter to be fitted to the end of the .7x lens. We are going to attempt to attach a 43.1 x .7 filter onto the end. We may have to glue it on. I could not locate a 42.5 x .7 polarizing filter anywhere. An adapter to 42mm x.7 or 43mm x .7 to 42.5mm x .7 would be great. The equipment and quality are great and customer service quickly took care of the error we had. Review: Excelent purchases.. very happy. - Ordered this product on desertcart.com to ship to Canada, lens and camera arrived within 2 working days. Both camera and lens from same seller were in tip top shape. I can't speak of the lens without mentioning the camera. The clarity of the 300x lens and 16MP Hayear camera combo are excellent with no distortion, or barrelling edge artifacts, and great color with proper LED lighting. ## Features - Objective Magnification Power by 0.7 - 4.5X(about 10 - 300X on the 21 inch display) - 1.0X C-mount adapter - Working distance: 100mm-115mm - focusing mechanism：Focusing handwheel tightness is adjustable，focusing range 15mm & 40mm ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B01CBCZPP4 | | Best Sellers Rank | #1,241 in Camera Lens Adapters & Converters | | Brand | HAYEAR | | Color | Black | | Customer Reviews | 4.4 out of 5 stars 38 Reviews | | Enclosure Material | Aluminum | | Item Weight | 630 Grams | | Light Source Type | LED | | Magnification Maximum | 300 x | | Manufacturer | HAYEAR | | Manufacturer Part Number | HY-300XA | | Material | Aluminum | | Model Number | HY-300XA | | Objective Lens Description | Achromatic | | Power Source | Battery Powered | | Real Angle Of View | 45 Degrees | | Real Angle of View | 45 Degrees | | UPC | 709619589462 | | Unit Count | 1.0 Count | ## Product Details - **Brand:** HAYEAR - **Color:** Black - **Item Weight:** 630 Grams - **Light Source Type:** LED - **Magnification Maximum:** 300 x - **Material:** Aluminum - **Objective Lens Description:** Achromatic - **Power Source:** Battery Powered - **Real Angle of View:** 45 Degrees - **UPC:** 709619589462 ## Images ![Monocular Max 300x Zoom C-Mount Glass Lens Adapter F/Industry Digital Microscope Camera Objective - Image 1](https://m.media-amazon.com/images/I/5169TFgvbNL.jpg) ![Monocular Max 300x Zoom C-Mount Glass Lens Adapter F/Industry Digital Microscope Camera Objective - Image 2](https://m.media-amazon.com/images/I/51i3AYcumAL.jpg) ![Monocular Max 300x Zoom C-Mount Glass Lens Adapter F/Industry Digital Microscope Camera Objective - Image 3](https://m.media-amazon.com/images/I/51IqCf8nwtL.jpg) ![Monocular Max 300x Zoom C-Mount Glass Lens Adapter F/Industry Digital Microscope Camera Objective - Image 4](https://m.media-amazon.com/images/I/51L0qQ+jxJL.jpg) ![Monocular Max 300x Zoom C-Mount Glass Lens Adapter F/Industry Digital Microscope Camera Objective - Image 5](https://m.media-amazon.com/images/I/61f3DdDFPyL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ This is a quality lens assembly! *by A***R on October 3, 2023* This lens is not a toy.
