In the ultra-wide-angle and macro categories, Canon Nikon mirrorless users have more lens options
With the hot sale of Canon Nikon mirrorless full-frame cameras, the Lao Frog lens will be more brand-specific after the launch of 15mmF2.0Rf mount and Z mount, 10-18mmF4.5-5.6Z mount The three lenses have also added RF mount and Z mount. They are 12mmF2.8 ultra-wide-angle “zero” distortion lens, 100mmF2.8 macro lens with “APO” apochromatic technology, and 25mmF2.8 macro lens with 2.5-5x magnification. In the ultra-wide-angle and macro categories, Canon Nikon mirrorless users have more lens options.
12mm F2.8 ultra-wide-angle and large-aperture full-frame SLR interchangeable lens, using a large-aperture glass aspherical lens, One medium-aperture glass aspheric surface, which effectively corrects the distortion aberrations. In order to ensure the performance of near zero distortion from infinity to close distance, the focusing method adopts two sets of main focusing group and auxiliary focusing group. Focusing, corrected the problem of excessive distortion caused by distance changes.
In order to solve the dispersion problem caused by the ultra-wide-angle and large aperture, this lens uses 3 abnormal dispersion glasses to greatly correct the dispersion aberration.
Each lens adopts a low-reflection multilayer film, which greatly eliminates ghosting and flare.
121-degree ultra-wide viewing angle, F2.8 large aperture, 18cm minimum focusing distance, allowing users to have more creative space.
Apochromatic APO High-performance and high-quality experience brought by technology
This lens is a macro lens under a full-frame system. It has an apochromatic APO technology that is not available under ordinary lenses. It can eliminate dispersion and make Shooting macro questions It is not affected by chromatic dispersion. From infinity to macro, it provides excellent imaging quality experience, and also provides stable and reliable support for users to reduce the workload in the later stage of the work.
Unique infinity to 2x magnification imaging, bringing a different macro experience
Different from the traditional macro lens, this lens has high performance in the full-frame system On the basis of imaging, high-resolution images can be taken from infinity to macro, and an amazing 2x object magnification is achieved in macro mode. The blessing of APO technology allows this lens to be imaged at double magnification. There is also no significant dispersion. A higher magnification ratio gives users more creative space.
circular aperture brings a soft blur effect
Sony mouth uses 13 diaphragm blades to form a circular aperture, which can make the point light source present a nearly circular virtual Effect. Gives a beautiful and soft blur out of focus. Canon uses 9 diaphragm blades and Nikon uses 7 diaphragms.
Auto iris brings more accurate exposure
Canon mount adopts automatic iris design, built-in electronic motor, can adjust the iris parameters through the body and record the aperture value and lens model. Data information. And in macro shooting, the maximum aperture can be maintained to focus, giving photographers a more convenient focusing experience.
is the same inside and outside, the excellent lens created by the reliable structure inside and outside
The inside of has 10 groups of 12 lenses, including two ED ultra-low dispersion lens structures to bring high-quality imaging. The outside has a mechanical structure made of all metal materials to ensure the durability of the lens for long-term use.
2.5 times MTF map
This lens is a super macro lens developed for full frame, which can magnify the subject by 2.5 to 5 times, which is higher than the general micro The distance lens can capture the unimaginable micro world.
The mechanical structure of this lens is all made of metal parts to ensure the accuracy and durability of the lens assembly.
has designed a tripod ring for this lens to ensure the photographer’s center of gravity control and the convenience of vertical shooting. The front end of the lens can be extended with the focus assist lamp accessories to increase the accuracy of focus.
In order to solve the limitation of the working distance of the high-magnification macro lens, this lens adopts a special optical structure, which increases the working area to about 4.5cm. The macro light distribution makes the photographer better Macro works.
The lens structure includes a low-dispersion lens to minimize optical dispersion.
