The following opinions have been automatically translated with Microsoft Translator. | Venus Laowa 6mm f/2 Zero-D MFT Pros: Size, weight, contacts for EXIF data, correction of optical defects, starburst effect, minimum focusing distance, lateral aberrations virtually absent at closed apertures. Cons: Rendering at the edges, ghosting with strong direct light, diffraction even at f/8. Manual focus only. Opinion: Stratospheric and unique lens of its kind, of this size and quality can only exist in the micro four-thirds world. The image quality, although not its workhorse, is decent, good in the center, inevitably decays at the edges. The best apertures are between f/4 and f/5.6, but at f/8, the aperture at which diffraction begins to appear, you have the best uniformity over the entire frame. You can also use it safely at f/11 and f/16 but you have to be well aware of what you are doing. The aperture is adjusted directly in the camera, while the focus is only manual (but it's not a problem at all, the depth of field is gigantic). This means that you don't have to set the focal length for stabilization, very convenient! With strong light directed into the frame (e.g. against the sun), ghosting is always present, while contrast hardly suffers (applause!). The distortion is corrected almost perfectly with the optical scheme, demonstrating to other manufacturers who rely on software corrections that it is possible to churn out small, well-built lenses of good optical quality even without relying on corrections in the machine. The color rendering is true to life. The star effect of the light points is undoubtedly the best of the micro four-thirds system. It starts with apertures just closed (even at f/4 the star is well formed) and is perfect between f/8 and f/11. A well-defined 10-pointed star with thin arms, a pleasure. The very wide angle of view makes the use of this lens not very easy, but it opens up to a very creative use of perspective. For me it is best in images set of a close-up subject, but it can also be used in images of natural and urban landscapes with a little foresight: the wide perspective includes many elements in the frame, making the composition not very easy. It is not a lens for everyone but a unique gem in the system. sent on January 06, 2025 |
 | Panasonic Leica DG Summilux 9mm f/1.7 ASPH Pros: Weight, compactness, reproduction ratio, resolution at short distances (even at the edges) Cons: Chromatic aberrations, build quality, infinity resolution, noisy autofocus, very high highlights Opinion: Lens purchased as a rectilinear alternative to the Olympus M.Zuiko Digital ED 8mm f/1.8 Fisheye Pro (lens of a completely different caliber) for ambient macro photography. This lens is ideal for short-medium distances, a context in which it gives its best showing excellent resolution over the entire frame even at closed apertures. At infinity, however, I noticed that it loses fine detail and in high-contrast areas aberration is very present. The distortion is corrected in the camera quite effectively. The out-of-focus areas are not particularly pleasant but have a very characteristic look. Coupled with an OM-1, the exposure of the lights is slightly high. Given the negligible weight, the build quality does not cry out for a miracle, it does not return particular solidity in the hand. The lens hood is a toy. I wouldn't buy this lens for landscape but for closeup/mid-distance photography, where it performs best. sent on September 01, 2024 |
 | Olympus M.Zuiko Digital ED 8mm f/1.8 Fisheye Pro Pros: Size & Weight, Image Quality, Brightness, Tropicalization, Reproduction Ratio Cons: Slight purple fringing in certain situations Opinion: Fantastic super bright fisheye lens. The good reproduction ratio allows you to take high-quality ambient macro photos. The minimum focusing distance allows you to get closer to about 1cm from the front element: at these very short distances, even with a focal length of 8mm, the depth of field is very shallow and the bokeh becomes distinctly "swirly" at full aperture. With an f/5.6 aperture you can generally keep the whole subject in focus, with a legible and pleasant blur of the background, allowing you to contextualize the photo. Sharpness, especially in the center, is very good even at full aperture, ensuring high performance for night photography and astrophotography at relatively low ISOs. In situations of high contrast at relatively wide apertures, the presence of a slight purple fringing that can be easily eliminated in post-production is highlighted. In combination with Olympus/OM bodies, you can correct fisheye distortion to use the lens as a straight wide angle, however fisheye distortion is the reason I bought this lens and is one of the reasons why it's really fun to use. sent on January 15, 2024 |
 | Samyang 135mm f/2 ED UMC Pros: Image quality, sharpness, bokeh, bright aperture, price Cons: Loss of contrast in backlight, weight, absence of contact, green cast Opinion: Spectacular optics to say the least for the selling price. The image quality is impressive, the sharpness is very high already at f/2 and improves when the aperture is closed. Incredibly creamy bokeh with well-defined bubbles of highlights in the background. Optically corrected chromatic aberration, almost non-existent. Well-frictioned and precise focus ring, aperture ring with half-stop increments (f/2 to f/22). Excellent build quality, which raises the weight to almost 1kg. Fortunately, the lens is compatible with a ring for Sony FE 24-240 mm, an accessory I would say almost indispensable. Good reproduction ratio (1:4, which becomes 1:2 on m4/3 cameras, I use it on OM-1) which, together with the minimum fairly close focusing distance, make it a perfect lens for artistic nature photography of flowers, fungi, insects etc... Since it has no contacts, the machine does not save the exif data. It suffers from a large loss of contrast in strong backlight situations. My specimen has a green cast that can be easily corrected in post-production by acting on the color temperature. It is not a tropicalized lens. It seems that it takes up the optical scheme of a Zeiss lens, and the results can be seen. Great goal. sent on January 08, 2024 |
