Laowa 15 mm f/4 Wide Angle Macro with shift function by Venus Optics

Company

Venus Optics was founded in 2013. Founder, managing director [2] and chief developer is Dayong Li [3] who graduated in opto-electronic engineering from the Beijing Institute of Technology.[4]

The company develops and produces innovative[5] [6] photographic lenses under the brand name Laowa ('old frog').

Lenses
Laowa 9 mm f/2.8 super wide angle lens for APS-C, introduced in 2015
Laowa 25 mm 2.5-5x ultra macro lens for full frame, introduced in 2018

The first lens was the 60 mm f/2.8 2 x Ultra Macro, a full frame lens with a magnification factor of 2:1 that could also be focused to infinity which is unique.[7] In the same year, Venus Optics released the widest angle macro lens to offer a 1:1 magnification ratio, the 15 mm f/4 Wide Angle Macro. The small focal length allows to include the background details (e.g., where and how the subject lives) in the photo. Due to physical reasons, the working distance in the macro range is rather short (at 1:1, focusing distance is 12.2 cm resulting in a working distance of only 4.7 mm).[8][9][10] In the meantime, Venus Optics have released unique lenses mainly in the fields of ultra macro and rectilinear and/or fast ultra wide angle lenses for full frame, APS-C, MFT, and Fujifilm G-Mount (see table).

Laowa lenses (July 2020)[9]
Focal length [mm] Max. aperture Image sensor format Focal length, full frame equivalent [mm] Name Year of introduction Unique feature at date of introduction
4f/2.8MFT8Fisheye MFT2019Smallest focal length for MFT. Ultracompact and thus suited for drone photography.[11]
7.5f/2MFT15MFT2017Combination of fast lens, ultra wide angle lens, and rectilinear projection for MFT. An ultra light version is available for drone photography.[12]
9f/2.8APS-C13.5Zero-D2018Combination of fast lens, ultra wide angle lens, and rectilinear projection w/ negligible distortion for APS-C. Ultracompact construction. A MFT version is available.[13]
9t/2.9APS-C13.5Zero-D Cine2020Ultra wide angle cine lens with rectilinear projection and negligible distortion for APS-C.
9f/5.6Full frame9Zero-D2020Widest angle rectilinear full frame lens with negligible distortion.
10-18f/4.5-5.6Full frame10-18Zoom2018Greatest zoom factor of a full frame wide angle lens.[14]
12f/2.8Full frame12Zero-D2016Combination of fast lens, ultra wide angle lens, and rectilinear projection w/ negligible distortion for full frame format.[15]
12t/2.9Full frame12Zero-D Cine2020Cine version of the 12 mm f/2.8 Zero-D. Field of view is 122°. Close to being distortion-free. Compact and relatively light for a cine lens. Minimum focusing distance is 7" (18 cm).[16]
15t/2.1Full frame15Zero-D Cine2020Wide angle cine lens with rectilinear projection and negligible distortion.
15f/4Full frame15Wide Angle Macro2015Widest angle macro lens. Shift function for landscsape format.[17]
15f/2Full frame15Zero-D2017Fastest 15 mm lens for full frame. Rectilinear projection, minimum distortion.[18]
17f/1.8MFT34Prime2019Very compact and light weight lens (172 g) and thus also suited for aerial photography. Small minimum focus distance of 5.9″ (15 cm) enables close-up shots.[19]
17f/4Fujifilm GFX13.5Ultra-Wide GFX Zero-D2019Widest angle lens for Fujifilm G-Mount. Rectilinear projection, minimum distortion.[20][21]
24f/14Full frame252x Macro Probe2018Novel concept. Allows for large distance between photographer and object. Can be immersed in aqueous media.[22]
25f/2.8Full frame252.5-5x Ultra Macro2018Most compact construction in this class with approximately 4 cm working distance (cf. Mitakon Zhongyi 20 mm f/2 4.5x Super Macro Lens and Canon MP-E 65 mm f/2.8 1–5x Macro).[23]
60f/2.8Full frame602x Ultra Macro2015First 2x macro lens that can be focused at infinity.[17]
65f/2.8APS-C97.52x Ultra Macro APO2020Apochromatic lens. Compact and lightweight APS-C version of the 100 mm 2x Ultra Macro f/2.8. Can also be focused at infinity.
100f/2.8Full frame1002x Ultra Macro APO2019Apochromatic lens. Laowa's second 2x macro lens after the 60 mm f/2.8 that can be focused at infinity. Minimum chromatic aberration.[24]
105f/2 (t/3.2)Full frame105Smooth Trans Focus (STF)2016Built in apodization element for creative photography.[25]

Most Laowa lenses (an exception is e.g., the 100 mm f/2,8 2x Ultra Macro APO) are purely manual lenses. There is no communication between the camera body and the lens, hence, no transfer of Exif data, no autofocus function, no lens-based image stabilization (OIS), and no automatic aperture control. However, autofocus plays a minor role in macro and wide angle photography. Auto focus bracketing is not possible with manual lenses. The company does not exclude the development of more lenses with electronics in them.[6]

gollark: I use nano, yes, but mostly VS Code for editing tasks.
gollark: I am not actually *that* good at programming.
