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

Venus Optics (Anhui ChangGeng Optics Technology Co., Ltd.) is a Chinese manufacturer of photographic lenses, specialized in the design of innovative macro and wide angle lenses. Headquarters and production site are in Hefei, sales and marketing are located in Hongkong and the USA.

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
4 f/2.8 MFT 8 Fisheye MFT 2019 Smallest focal length for MFT. Ultracompact and thus suited for drone photography.[11]
7.5 f/2 MFT 15 MFT C-Dreamer 2017 Combination of fast lens, ultra wide angle lens, and rectilinear projection for MFT. An ultra light version is available for drone photography.[12]
9 f/2.8 APS-C 13.5 Zero-D (C-Dreamer, C&D-Dreamer) 2018 Combination of fast lens, ultra wide angle lens, and rectilinear projection w/ negligible distortion for APS-C. Ultracompact construction. A MFT version is available.[13]
9 t/2.9 APS-C 13.5 Zero-D Cine 2020 Ultra wide angle cine lens with rectilinear projection and negligible distortion for APS-C.
9 f/5.6 Full frame 9 Zero-D (W-Dreamer) 2020 Widest angle rectilinear full frame lens with negligible distortion.
10-18 f/4.5-5.6 Full frame 10-18 C-Dreamer 2018 Greatest zoom factor of a full frame wide angle lens.[14]
12 f/2.8 Full frame 12 Zero-D (D-Dreamer) 2016 Combination of fast lens, ultra wide angle lens, and rectilinear projection w/ negligible distortion for full frame format.[15]
12 t/2.9 Full frame 12 Zero-D Cine 2020 Cine 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]
15 t/2.1 Full frame 15 Zero-D Cine 2020 Wide angle cine lens with rectilinear projection and negligible distortion.
15 f/4 Full frame 15 Wide Angle Macro (W-Dreamer) 2015 Widest angle macro lens. Shift function for landscsape format.[17]
15 f/2 Full frame 15 Zero-D (D-Dreamer) 2017 Fastest 15 mm lens for full frame. Rectilinear projection, minimum distortion.[18]
17 f/1.8 MFT 34 C-Dreamer 2019 Very 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]
17 f/4 Fujifilm GFX 13.5 Ultra-Wide GFX Zero-D 2019 Widest angle lens for Fujifilm G-Mount. Rectilinear projection, minimum distortion.[20][21]
24 f/14 Full frame 25 2x Macro Probe 2018 Novel concept. Allows for large distance between photographer and object. Can be immersed in aqueous media.[22]
25 f/2.8 Full frame 25 2.5-5x Ultra Macro 2018 Most 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]
60 f/2.8 Full frame 60 2x Ultra Macro 2015 First 2x macro lens that can be focused at infinity.[17]
65 f/2.8 APS-C 97.5 2x Ultra Macro APO 2020 Apochromatic lens. Compact and lightweight APS-C version of the 100 mm 2x Ultra Macro f/2.8. Can also be focused at infinity.
100 f/2.8 Full frame 100 2x Ultra Macro APO 2019 Apochromatic lens. Laowa's second 2x macro lens after the 60 mm f/2.8 that can be focused at infinity. Minimum chromatic aberration.[24]
105 f/2 (t/3.2) Full frame 105 Smooth Trans Focus (STF) 2016 Built 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]
