Built for extreme close-up imaging, the Sony E-mount AstrHori 25mm f/2.8 Ultra Macro Lens for Sony Efrom AstrHori 25mm f/2.8 Ultra Macro Lens for Sony Eis a specialized macro lens for photographing subjects at magnifications greater than life-size. Operating within a 2:1 to 5:1 maximum magnification range, this sophisticated prime lens has a minimum focusing distance of just 4.4" at the 2:1 magnification and 7.3" at 5:1, along with a comfortable working distance of 1.5-1.8". The wide-angle focal length allows the lens to achieve greater depth of field compared to long focal length macro lenses. Complementing the close-up capabilities, the optical design incorporates extra-low dispersion and high-refractive elements to enhance color fidelity and image clarity. Additionally, distinguishing itself from other macro lenses, this 25mm f/2.8 is lightweight at just 1 lb, making it easy to handle.

Related Questions and Answers

Q: 1. ¿WIll this lens work with a Nikon Z 5 with the FTZ adapter?

A: Yes, it will work.

Q: 2. Can this lens be adapted with a smart adapter to shoot on the Fujifilm GFX?

A: A smart adapter would have no benefit for use with the Venus Optics Laowa 25mm f/2.8 2.5-5X Ultra Macro Lens for Canon EF. Smart adapters are designed for lenses that have electronic contacts and allow communication to remain between the camera and lens to assist with transmitting autofocus, automatic metering, automatic exposure, and image stabilization features. The Venus Optics Laowa 25mm f/2.8 2.5-5X Ultra Macro Lens for Canon EF is a fully manual lens and has no electronic contacts and would have no benefit from a smart adapter. I would instead recommend either the Vello Canon EF/EF-S Lens to Fujifilm X-Mount Camera Lens Adapter with Aperture Control, B&H # VELAFXCEFA, or the FotodioX Canon EF Pro Lens Adapter with Built-In Iris Control for Fujifilm X-Mount Cameras, B&H # FOPFXACEI, for your usage needs. As your lens has a built-in aperture ring, if you are looking for a more economical adapter, the Vello Canon EF/EF-S Lens to Fujifilm X-Mount Camera Lens Adapter, B&H # VELAFXCEF, would work for your usage needs, but the first adapters I listed would allow you to adjust the aperture on Canon lenses that do not have aperture rings. Unfortunately, there are no Smart Adapters designed for maintaining communication between Canon EF lenses and the Fujifilm X-mount lens mount.

Q: 3. I know Venus Optics has a CanonFE to Micro 4/3s adapter on their website and B&H don't appear to have in their catalog. Would ANY generic adapter (such as https://www.bhphotovideo.com/c/product/1413074-REG/fotodiox_eos_mft_lens_mount_adapter_for.html) work with this lens?

A: Yes, any EF to MFT adapter will work.

Q: 4. So, for those who have this lens, what do you use for a flash?

A: The Venus Macro Twin light is a good macro light option for the 25mm Ultra Macro lens. https://bhpho.to/2v1d2DM

Q: 7. It works for APS-C camera

A: It works for APS-C Canon cameras where it provides a 40mm equivalent focal length

Q: 8. For a first real macro lens would you recommend this of the 60mm Laowa 2x ?

A: You could with this lens but it may be a little too advanced for a first time macro shooter. You want to look at the Canon 60mm 2.8, if you have a cropped sensor camera or the Sigma 70mm macro for a full frame.

Q: 9. Is it compatible with Sony a6400 camera?

A: Yes, the lens is designed and made for all E mount body systems.

Q: 10. Can I use this lens with Panasonic GH5?
