1. Achromatic Design: This lens is an achromatic doublet, which means it has been designed to minimize chromatic aberration, a common issue in lenses that can result in color fringing.
2. Large Aperture: With a maximum aperture of f/10, this lens allows for a greater amount of light to enter, which can be beneficial in low-light situations or for creating shallow depth of field effects.
3. Reasonable Focal Length: A 100mm focal length provides a moderate telephoto perspective, making it suitable for various applications like portrait photography, macro, and some wildlife photography.
4. Single Glass Material: This lens is made from a single piece of glass, which can contribute to its durability and simplicity.
Cons:1. Limited Aperture Range: With a maximum aperture of f/10, this lens might not be as versatile as some other lenses with a wider aperture range.
2. Manual Focus: The lack of autofocus might require more manual adjustments, especially for certain types of photography.
3. Potential Quality Concerns: As a budget-friendly option, there might be some compromises in terms of image quality compared to more expensive lenses.
4. Lack of Special Features: This lens does not seem to have any additional features like image stabilization or weather-sealing.
Conclusion:The 14040-100 Dbl Achromat Doublet Single Glass Lens offers a balanced combination of features for a competitive price. Its achromatic design and large aperture make it suitable for various photography needs. However, its limited aperture range, manual focus, potential quality concerns, and lack of special features should be considered before making a purchase.
Recommendation:If you're looking for a budget-friendly lens with good chromatic aberration correction and a decent aperture for moderate telephoto photography, this lens could be a good choice. However, if you require more advanced features, autofocus, or a wider aperture range, you might want to consider other options in the market. Always ensure to test the lens yourself if possible to assess its performance based on your specific needs.
Holding it in front of a light source and moving around, that seems plausible, its best image is about 4 away from test piece paper. 8mm 2 lens, its thick and the paperwork in photo says it has a 100mm effective focal length .
Please look at the photos, which include exact sticker that was on box - it looks like this is a used lens someone analyzed and labeled. It is as is, I have no way other than the crude measurements mentioned of verifying these specifications.
