Among the domestic lens manufacturers, there is such a manufacturer that has been quietly working in the field of macro photography. In addition to the unique shape of the lenses it produces, everyone is surprised by the excellent workmanship and reliable imaging. He also has his own loyal user group, and he is Anhui Chang Geng Optical Technology. Of course, in addition to the macro lens, Lao Frog also does very well in other lenses.
Today we will not talk about anything else, just talk about me not long ago The old frog CF65mmF2.8CA-DreamerMacro2X lens I got, because it is an APS-C format lens, roughly equivalent to a full-frame 100 micro lens, the lens has three body mounts: Fuji X-mount, Sony E port, Canon EF-M port, the version I got this time is Fuji X port.
Old frog CF65mmF2 .8CA-DreamerMacro2X has a slight change in the outer packaging compared to the previous one. This time the packaging is decorated with a white-based color gradient ribbon and color ring, and this color embellishment seems to be the color reflected by the lens coating. It is more advanced and more refined in terms of texture.

The package box contains the lens manual, warranty card and other information and Lens hood. The old frog CF65mmF2.8CA-DreamerMacro2X lens, including the focus ring, hood and aperture ring, is made of metal as a whole, and the overall feel is very good. The solid metal material not only provides a reliable guarantee for the lens group and enhances the durability of the lens, but also has a certain pressure feeling. A proper pressure feeling will also provide a better shooting experience and feeling for the shooting process, especially for The proper pressing feeling when holding macro shots can provide stable support to a large extent, so that users will not feel top-to-head when pressing the shutter.

Old frog CF65mmF2.8CA-DreamerMacro2X lens body color still continues the traditional design of the old frog, the overall blackened design surrounds a blue circle in the front of the lens. Below the blue circle is the English LOGO of the old frog and the focal length, aperture, magnification, and the size of the lens. The display of the lens information can be said to be clear at a glance.

Although the old frog CF65mmF2.8CA-DreamerMacro2X is used as a manual lens, it is still remarkable in terms of operating feel. The rotation of the focus ring has a soft operating feel, and the rotation of the aperture ring also has a clear sense of passage when switching the aperture. During the shooting process, the photographer can easily control the aperture size with the clear sense of passage when switching the aperture.

lens group design, the old frog CF65mmF2.8-DreamerMacro2X adopts the lens group design of 10 groups and 14 elements, including 3 abnormal dispersion glasses. According to the information provided by the manufacturer, the lens also adopts the “apochromatic” APO technology that the pass lens does not have, which can completely eliminate the dispersion and is not affected by the chromatic dispersion during shooting. As for whether the “apochromatic” APO technology adopted by Lao Frog will completely eliminate the dispersion phenomenon, we will verify its effect in the following formal tests.
The compact lens structure of the old CF65mmF2.8CA-DreamerMacro2X also creates a compact and portable lens volume, just because the filter diameter of the old frog CF65mmF2.8CA-DreamerMacro2X is only 52mm, so it is visually The effect seems to be a bit slender, but this is also its characteristic. It has good shooting performance when paired with APS-C format cameras. At the same time, it also takes into account portability to a large extent. The convenience of small and portable features allows users to either It is very convenient to carry around for shooting outdoors or going out to play.

Resolution real shot test
With the continuous development of the camera, the pixel of the camera is getting higher and higher, and the presentation of picture quality is also increasing The finer the camera, the higher the requirements for the presentation of the lens and the higher the performance of the body. Before the macro shooting, we first conducted a regular image quality test. We all said that there is no underdog in the macro. Therefore, I did not perform the conventional 1:1 and 2:1 resolution performance of the real shots. Macro shooting, the actual performance of the macro will be shown in the macro real shooting below. This time I chose a newspaper with a focus distance of about three meters for shooting, and then zoomed in 100% on the center and edges of the frame to observe the resolution performance.

From the actual shooting point of view, the overall image quality of the old frog CF65mmF2.8CA-DreamerMacro2X lens is not bad, but At the maximum aperture, the image quality of the center and the edge is slightly loose. When the aperture is contracted by one or two stops, both the center image quality and the edge image quality have a more obvious improvement; and from the aperture f/ Starting from 16, the sharpness and contrast of the center and edge image quality have been reduced due to lens diffraction, but overall the performance of this lens from the maximum aperture of f/2.8 to f/8 is relatively balanced. Basically, the pictures taken under each stop aperture can easily reach the usable state.
From the official data, we can know the old frog CF65mmF2.8CA- DreamerMacro2X adopts the lens design of 10 groups and 14 elements, and also has the blessing of “apochromatic” APO technology, which can completely eliminate the dispersion phenomenon. In order to test the extent to which the old CF65mmF2.8CA-DreamerMacro2X lens eliminates dispersion in actual shooting, I deliberately shoot silver reflective metal to observe the dispersion when the sun is strongest at noon.

Because the old frog CF65mmF2.8CA-DreamerMacro2X is a manual lens, it cannot record the aperture value information when shooting with Fuji X-Pro. In the above two photos, I used the minimum aperture and maximum aperture to shoot separately. Judging from the actual shooting results, the “apochromatic” APO technology really makes the old frog CF65mmF2.8CA-DreamerMacro2X lens even if it is There is no chromatic aberration in the shooting when the light is the strongest, and the performance of such dispersion elimination is very commendable.
background blur test
telephoto macro lens is used by many photographers or photography hobbies Sometimes the photographer is not just using it as a single macro lens. In many cases, photographers will also use the characteristics of the telephoto and large aperture of the macro lens to shoot portraits or still life and other subjects. CF65mmF2.8CA-DreamerMacro2X as an APS-C frame telephoto macro, the performance in terms of blur, I believe everyone is also looking forward to it.

Maximum Aperture Blur
From the perspective of the shooting blur effect, the CF65mmF2.8CA-DreamerMacro2X lens’s maximum aperture bokeh performance is fair Yes, it can be seen from the blur of the background light that the blur in the center of the picture is still oily and the transition of the circular light spot in the center of the picture is also very uniform, there is no phenomenon of onion rings, but the background light at the edge appears illusory A certain degree of caliber erosion phenomenon. Next, let’s take a look at the background blur effect of a few portrait shots and see if the background blur in the outdoor environment can also be smooth and smooth.

The red area in the second portrait is the out-of-focus real shot screenshot area. From the 100% enlarged image of the out-of-focus screenshot, the old frog CF65mmF2.8CA -DreamerMacro2X This lens benefits from the 9-piece aperture blade design, which makes the background blur transition in portrait shooting very oily and can present a soft and beautiful out-of-focus effect.
sample shots and summary
At the end of the article, let’s talk about the old frog CF65mmF2. The macro shooting experience of the 8CA-DreamerMacro2X lens, and a summary of the detail display ability of this lens for macro shooting. Shooting with a macro lens often allows us to discover a microscopic world that we have never paid attention to or cannot detect before. At this time, the magnification ability of the macro lens is the most important indicator. The closer the image, the more powerful it is.

I used double magnification and a large aperture to shoot the coin and found that the old frog CF65mmF2.8CA-DreamerMacro2X lens also showed good strength. The texture on the coin can be said to be clear. Here, I would like to remind you that double magnification and large aperture shooting will make the depth of field of the picture very shallow, which is difficult for general users to shoot handheld. I recommend using a tripod and 2X magnification during shooting. When shooting, due to its small depth of field, a perfect work is taken through depth synthesis; and in order to better show the texture of the subject, sufficient light is also one of the necessary conditions.
Editor’s point of view:
Among many domestic lens brands, Laowa uses macro It is unique with the ultra-wide-angle lens. The old frog CF65mmF2.8CA-DreamerMacro2X that I have used recently has left a deep impression on me, whether it is from in-focus imaging or out-of-focus blur, or its powerful portability. Give me enough surprises. I believe that the compact and concise design and excellent imaging performance of this lens will bring more surprises to many photographers, and it will also shine in the field of macro subjects. The current Jingdong price is 2,498 yuan.
