Opto Engineering C-mount 0.1-0.9x Macro Lens For 2/3" Detector
- Product Code: eq180044
-
The C-Mount 0.1-0.9x f/5.5-3.0 Variable Macro Lens from Opto Engineering is a multi-configuration macro lens suitable for inspection of object sizes ranging from a few millimeters to some centimeters. Magnification and focus can be tuned by adjusting a lockable rotating knob. The lens magnification range can be selected by means of a set of extension tubes. This makes the lens ideal for prototyping purposes and machine vision applications requiring flexibility. Since the working f-number increases with the magnification, the optimum combination of field depth, image resolution, and brightness is maintained in any lens configuration. Moreover, the optical distortion approaches zero at any magnification, making this lens suitable for measurement applications.

Related Questions and Answers
Q: 1. I have Otus 55...will this lens be equal/better/worse?
A: The ZEISS Milvus 50mm f/2M ZE Macro Lens for Canon EF is a macro lens and the ZEISS Otus 55mm f/1.4 ZE Lens for Canon EF is not. Optically the 55mm is a higher level line and is sharper.
Q: 2. Is this lens weather sealed?
A: Voigtlander does not list if the Voigtlander Macro APO-Ultron 35mm f/2 Lens for FUJIFILM X-Mount is or is not weather sealed. Chances are it is not.
Q: 3. Certainly the Macro range is great but how does it compare to standard lenses when you are doing landscapes or anything focused farther away?
A: The ZEISS Milvus 2/50M uses a floating lens element design that optimizes performance from close focus through infinity. As a result, the lens serves a dual purpose as either a close-up macro lens, or a general purpose standard lens.

Q: 4. Is there a firmware update to make this compatible with the Nikon Df?
A: No, the ZEISS Milvus 50mm f/2M ZF.2 Macro Lens for Nikon F is already compatible with Nikon Df.
Q: 5. Is the diaphragm electronically actuated like a Fuji lens with an aperture ring? Or is it fully manual old school?
A: This lens is fully manual with an aperture ring. However, the lens does have an electric contact point to communicate not only the lens aperture but also the framing for the focus throw. This is very useful for the Fuji's X-pro-3 OVF.
Q: 6. Is this lens a true flat field macro suitable for use on a copy stand?
A: Yes, this lens is ideally suited for copy work. You can view the distortion characteristics on the data sheet located using the link below. a href= http://www.zeiss.com/content/dam/Photography/new/pdf/en/downloadcenter/datasheets_milvus/milvus250m.pdf target= _blank http://www.zeiss.com/content/dam/Photography/new/pdf/en/downloadcenter/datasheets_milvus/milvus250m.pdf/a
Q: 7. why is the milvus 50mm f/2M more expensive than milvus 50mm f/1.4 ? was thinking about buying, but dont know which one to get.
A: I'm pretty sure all macro lenses tend to be more expensive than their normal counterparts in the same focal length. This likely has to do with the focus helicoid it self being more complex since it needs to stay consistent throughout a considerably longer range. I chose it over the 50mm 1.4 because I needed the close focus ability for food shots and really like the recessed and smaller front element for backlit shots as well. So far this lens is a rock star, the build quality of this new line is peerless.
Q: 8. Is there any noticeable focus breathing when shooting video ?
A: 50mm lenses, even cheap ones, barely breathe at all. I would suspect you would need a laser microscope to measure the breathing on any Zeiss 50mm Milvus.
Q: 9. I am a serious panoramic photographer, my question is how is this lens perform the sharpness at infinity? i have a nikkor 55mm f/2.8, i don't like it perform at infinity. Thank you!
A: The ZEISS Milvus 50mm f/2M ZF.2 Macro Lens for Nikon F has remarkable sharpness performance when focused at infinity.
Q: 10. How does the "macro" function work? Does the adapter change in thickness by rotating?
A: You are correct. Rotate it and a helical gearing extends the lens so that it can focus closer.
