Dedicated to extreme close-up imaging, the Pentax K-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.
- K-Mount Lens/Full-Frame Format

Venus Optics Laowa 25mm f/2.8 Ultra Macro Reviews
A MUST Have for a Macro Photography
If you want 2.5 to 5x magnification and super sharp images this is your lens! Remember it is all manual, but that is really not an issue. On a Nikon Z it works exceptionally well with the Focus Stacking feature you have incredible depth of field images. A bargain at $500 !!! A++ with a Focus Rail (I use the NiSi or WeMacro).
You MUST use it on a focus rail and you will get truly excellent images all the way to 5x. An amazing lens at an amazing price. The quality of the images is outstanding but you have to use it correctly!!
What A Surprise!
This lens doesn't let you focus, so you need to move around until it's in focus. But when you do, you see a whole different world, and in such great detail. For the price, this lens is a must if you want to shoot what the eye can't see.
Works just fine
This lens takes a LOT of getting used to and does have a learning curve. Once you get the hang of it, the Laowa 25mm produces fine images at jaw breaking magnification.
Getting closer with good glass is crucial
This lens, and the miniatures I received for Christmas will be well captured (artistic skill aside). Thank you.
Good macro lens
I bought this lens for my son's project. I didn't expect high image quality at this price but it is actually pretty good. Working distance is around 2 and very useful. Zoom ring (I don't know the proper name) is a little tough to move. This lens does not have any manual focus ring nor auto focus, so you need to have a macro focusing rail slider and a tripod.
Fantastic lens when used in the right conditions
I've been using the Sony 90mm macro for a couple years, paired with a Sony A7riii and have loved every minute with it. But I wanted something for super macro photos. So I paired the Laowa 25mm with a Wemacro rail (for stacking) and the results are astounding. The lens is ridiculously sharp from center to edge. The lack of manual focus is off-putting, and no IBIS makes it impossible for me to use when not on a tripod or rail. But those are minor gripes in my situation. If you love macro and can work around the challenge of this lens, I would highly recommend it!
Just amazed with the quality of the built and the sharpness for such low price
