Venus Optics 25mm f/2.8 overview

  • 1Description

Dedicated to extreme close-up imaging, the Canon EF-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.

Prime 25mm f/2.8 is designed for full-frame Canon EF-mount DSLR cameras, however can also be used with APS-C models where it provides a 40mm 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 25mm f/2.8 reviews

    Laowa 25mm f/2.8 2.5-5X Ultra Macro Lens for Canon EF is rated 4.7 out of 5 by 3.
    Rated 5 out of 5 by from Really magnifies! Got my new super macro lens and began trying to use it. It has no electronic connection to the camera (no contacts). It just connects mechanically. The camera cannot determine what the lens is doing. The aperture closes down as you set it. But that gives you a good idea how dark your image will be. Very difficult to use with only a flash, because you cannot see to manually focus it (no auto-focus). If you provide a strong bright continuous light, it works fine. You can move the light around to try different angles and brightness and directly see what you will get. Does not have infinite focus. Will only focus a couple of inches from the lens. Depth of Field is probably less than a millimeter. Was able to manually "focus" using the view finder, but much better using a magnified live view. The major focus is just to move back and forth until the subject is in the millimeter of focus. The lens "focus" is really just twisting the f-stop ring and changing the length and magnification. With some practice, I could get the focus right where I wanted. It is amazing how much it magnifies! It was fun trying to find something small enough, so that you could see the whole subject in the frame. Attached is an uncropped photo of a single grain of table salt and a photo of tiny chia seeds. Really fun (but challenging) to play around with! Next I may get a focus rail and try some focus stacking.

    Rated 4 out of 5 by from Challenging... With Superb Image Quality First, let me begin by saying that I am a published photographer who sells stock images. Second, this should not be considered a recommendation as I have only been shooting with this lens for two weeks, but I will share with you what I have learned so far. I have found the most challenging aspect of this lens to be an EXTREMELY HARD TO TURN magnification (focusing) ring, which makes using this lens without a focus rail extremely tricky...but not impossible. As expected lack of light in the viewfinder is an issue with this lens, and the greater the magnification the less light. When composing the shot use f 2.8 to take advantage of the most available light, then click to f 8 or higher to shoot your image utilizing better depth of field. A good flash system with this lens is a necessity for me. Use a flashlight or focus light to help illuminate the subject while composing the shot. As you may have already guessed, this lens would be very limiting when trying to shoot live subjects in the field. The build quality of the Laowa is like that of a Sherman tank. Even the lens cap is metal and screws on...just make sure you align the two red marks or it will not click secure. The image quality of this lens is superb. My attached photo of the eyes of a tiny Holocephala Robber Fly shows what this lens is capable of. I actually added a set of Vello 49 mm metal extension tubes to the lens in this case, because this insect measures a mere 2 mm across both eyes! If you shoot with a full frame camera you will need to add a set of these very sturdy and inexpensive tubes to allow you to fill most of the frame with very tiny insects, because even 5x magnification will not be enough. I shot this image in studio WITHOUT a focus rail with my Canon EOS 6D affixed to a table. I utilized my Yongnuo flash system, two on either side and one above the subject. When focusing with the lens focus ring for a stacked image, the ring must be BARELY turned with each shot requiring either superb nearsighted vision or a magnifying glass to see the smallest movement, hence the difficulty of using this lens' stiff focusing ring for a focus stacked image. The attached image is a ten image stack that I produced with a good focus stacking software. So far I have used this lens to produce five exceptional images and I have high hopes for the Laowa 25mm in the future.
