In the past few years, the old frog has introduced several very interesting lenses. Like some other Chinese manufacturers, they focus on quite extreme design. Their 24mm F14 2x macro probe lens is probably the most exotic, and is now quite famous in the video field. We are very impressed by the more conventional macro lens 65mmf2.822x apo ultra macro and 100mmf2.82x ultra macro apo full frame lens for APS-C non reflection camera. However, the old frog did not forget the M43 lens group. Therefore, in this evaluation, we are going to discuss the new old frog 50mmf2.82x ultra macro apo lens. Is this a fully manual lens again? Not exactly. This lens provides electronic contacts, so EXIF data is available, and you can also control the aperture with the camera. For better or worse, the lens no longer has an aperture ring, but it is still a manual focus lens. Therefore, in order to focus accurately, we need to use magnifying focus. After setting the camera, the zoom in and focus function of the camera can be activated by turning the focusing ring. It should be noted that the old frog is not involved in the firmware updates provided by Panasonic or Olympus. < / P > < p > in terms of price, the price of old frog is relatively bold, and the price is 399 US dollars. That’s close to the price of the Olympus M. Zuiko 60mm f2.8 ed macro lens, which costs $100 more. However, the old frog can provide a maximum magnification of 2:1, so if you like extreme macro photography, just based on paper specifications, the old frog already has some added value. < / P > < p > continues the good tradition of M43 system. The old frog 50mmf2.82x ultra macro apo is small and light. However, this does not have a negative impact on manufacturing quality. Although it doesn’t offer any form of all-weather design, it’s made of all metal and durable. In addition, it is worth pointing out that the mirror body will not stretch during the focusing process. The focusing ring operates smoothly. A barrel lens cover is also included in the package. < / P > < p > the M43 camera automatically corrects the dark angle unless it turns off itself. The old frog is a little radical here, not only to reduce, but also to eliminate the dark corner, but also to increase the corner noise under the large aperture, there is no problem. < / P > < p > so far, the macro lenses released by Laowa are very sharp, and this 50mmf2.82x ultra macro apo is no exception. In the f 2.8 aperture, the center has been very good, and the edge image quality has reached a very good level. Shrinking the aperture does not increase the sharpness of the center, but the quality of the edges and corners has been slightly improved, and it will be slightly improved at f5.6. Generally, in M43 system, diffraction effect starts from F8. However, the sharpness of this lens in the F8 is still very good, in F11 is very enough. However, when shooting, try to avoid using F16 aperture, let alone F22. The transverse color difference of < / P > < p > is only 0.1px, which is almost negligible. The old frog has an apo design, so there is no vertical color difference. < / P > < p > the aperture of Laowa 50mmf2.82x ultra macro apo lens is quite large, so whether you plan to use it for portrait or macro shot, the quality of out of focus virtualization will become a major standard. < / P > < p > as shown in the figure below, the out of focus spot rendering is very good at f2.8 aperture. The interior area of the flare is very clean, with only a slight edge. However, when the aperture is contracted at F4, the edge of the aperture becomes a little obvious. Obviously, the diaphragm leaf of Laowa’s lens is not very round. < / P > < p > when viewing the light spot of the whole picture, you can notice that the shape of the light spot attenuates to the edge. This is a kind of mechanical vignetting effect, that is, “olive” light spot will only appear in the corner of the picture. Shrinking the aperture can improve the spot shape, but at the same time, the shape of the diaphragm blade will also appear. < p > < p > on the whole, the out of focus performance is not perfect, but it is already very good. The foreground blur is very soft and the background blur is very symmetrical, but it is a little stiff at high contrast. < / P > < p > the old frog 50mm f / 2.82x ultra macro apo MFT lens is an impressive lens with some minor defects. Its bright spot is the extremely high sharpness at the beginning of f2.8 and at f4-5.6. Thanks to the almost nonexistent horizontal and vertical chromatic aberration, the lens has a very high sharpness. There was no distortion. Although there are some dark corners under large aperture in raw files, most users will not find any dark corners because of automatic image correction. However, the out of focus effect of the lens can be better. In addition to the focus of f2.8, the edge of the spot is obvious, and the background can be more smooth. Glare is also a problem in backlight, so it’s best to install the provided hood when the light is not good. < p > < p > Laowa has finally made progress in camera integration. Providing electronic contacts is an important step towards mainstream products. Although the 50 mm f2.8 2x ultra macro apo MFT lens is still a manual focus lens, EXIF data and camera controlled aperture are finally possible. The focusing ring can also automatically trigger zoom in. At least in static scenes, accurate focusing is quite easy. The manufacturing quality is the same as the old frog products we have seen before, the same high level. Although it is very light, the lens feels very strong due to the all metal body. However, there is no all-weather sealing design. < / P > < p > now the question is, is there any reason to prefer the 50mmf2.82x ultra macro apo MFT lens to the Olympus m.zuiko 60mmf2.8 ed macro lens? If you’re a macro “extremist,” the answer is obvious – the old frog provides 2:1, while Olympus has only 1:1 maximum magnification. But while the old frog lens is sharper, Olympus offers better out of focus effects, less glare and, of course, autofocus. This is life – nothing is perfect. gather and watch!
