Dedicated to extreme close-up imaging, the Sony E-mount Laowa 25mm f/2.8 2.5-5X Ultra Macro from Venus Optics is a specialized macro lens for photographing subjects at magnifications greater than life-size. Operating within a 2.5:1 to 5:1 range, this lens has a minimum focus distance of just 6.8" at the 5:1 magnification along with a comfortable 1.6" working distance. This range is benefitted by the wide-angle focal length, too, in order to achieve greater depth of field compared to long focal length macro lenses. Complementing the close-up capabilities, the optical design incorporates one extra-low dispersion element to reduce color fringing and chromatic aberrations for a high degree of clarity. Additionally, distinguishing itself from other macro lenses, this 25mm f/2.8 is characterized by its notably sleek and lightweight design for easier handling and more room to work with artificial lighting.

Venus Optics Laowa 25mm f/2.8 Ultra Macro Overview
Prime 25mm f/2.8 is designed for full-frame Sony E-mount mirrorless cameras but can also be used with APS-C models where it provides a 37.5mm equivalent focal length.
Specifically developed for macro photography, this lens is designed for use within a 2.5:1 to 5:1 magnification range for producing greater-than-life-size imagery. This lens does not offer infinity focus.
When at 5:1 magnification, the lens has a minimum focusing distance of 6.8" along with a working distance of 1.6", which affords sufficient room for illuminating your subject. At the 2.5:1 position, a minimum focusing distance of 9.2" is possible along with a working distance of 1.8".
Wide-angle design benefits the high magnification design by providing greater depth of field compared to telephoto or long lens designs.
Manual focus operation for precise control over focusing distance when working with close-up subjects.
One extra-low dispersion element greatly reduces chromatic aberrations and color fringing for improved clarity and color accuracy.
Eight-blade diaphragm contributes to a pleasing out of focus quality when using shallow depth of field.
Especially slim and lightweight physical design is easier to use handheld and offers more room for illuminating close-up subjects.

Venus Optics Laowa 25mm f/2.8 Ultra Macro Reviews
Marvelous lens
By Anthony
Rated 5 out of 5

I bought this to pair with my Novoflex Castel-M focusing rail, and it is a match made in heaven. The lens itself is an excellent product, well-built, and a delight to use. When paired with the Castel-M, it provides a truly capable and pain-free setup for magnifications in the 2.5x to 5x range. Well worth the money!
Excellent piece of kit, but steep learning curve for me

Been taking flower focus stacks with Z9 on Nisi 200 rail, Godox DP400, & using Helicon software. My first experience doing manual stacks, with results so far being hit and miss...lots of artifacts in some cases. Also, I had no idea how much debris can collect on a Trader Joe's bouquet until I saw them at 5x.

So, for those who have this lens, what do you use for a flash?
The Venus Macro Twin light is a good macro light option for the 25mm Ultra Macro lens. https://bhpho.to/2v1d2DM

Will this work with Nikon D7500 crop senor
Will this work with Nikon D7500 crop senor
Yes, it will work with a crop sensor (Nikon DX format), but its magnification is increased from 2.5-5 to about 3.6-7.5. I use it with my D500, also DX format. Because it has such high magnification, it has very narrow depth of field, so it is a major challenge to use this lens unless you use a macro rail and focus stacking. Using it on a DX body is even more problematic, since the magnification is even higher.

Is there a focus ring on this lens to manually focus? I'm seeing confusing statements about the requirement of moving the camera to focus.
There is a ring that will extend the lens from out from 2.5-5x magnification. This is a prime/ fixed 25mm lens. It does not have a “focus” ring that you would find on a traditional zoom lens. You would have to move the camera to find your area of focus. This lens is best paired with a macro rail and tripod for that reason.

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?
Yes, any EF to MFT adapter will work.
