The following opinions have been automatically translated with Microsoft Translator. | Venus Laowa 60mm f/2.8 2x Macro Pros: 2:1 playback ratio, metal construction, uv filter provided (required... Unfortunately!). Cons: Important barrel distortion to any RR ratio, intolerable for a macro lens. Important vignette especially at the extremes of MAF. Interior of the barrel exposed to the weather (sic!!) from the front if used without filter. Ridiculous MAF dial excursion (less than 180 degrees) Opinion: I bought it, for reproduction work where I was interested in reaching playback ratios greater than 1:1 and in the Nikon list there was nothing that had this feature. What about... it was a disappointment how I had never had it in the course of my photographic "life"! Inconceivable distortion for a lens that also targets the reproduction of flat documents. The vignette is important throughout the excursion of MAF distances and at the extremes, especially with closed diaphragms, the corners of the frame are sharply cut. It's a lens designed to sufficiently cover the DX format (and on the packaging clearly appears the word DX, I noticed it later) but on FF it shows all its limitations. Let's talk about the rotation of the macaw of MAF: on the Micro Nikkor 55mm f3.5 you have a rotation of 330 degrees between infinity and 0.5x (40 years of optical design!), here, instead, you have to settle for less than 150 degrees between infinity and 2x, which makes a precise MAF really difficult maybe even with cameras equipped with focusing. As soon as I opened the package and picked up the optics I was pleasantly surprised by the presence of a UV filter screwed on the front... Well... never remove that filter!!, especially if you go to photograph in "field" in search of insects, flowers, shells etc. maybe with a wind that carries grains of sand or other, directly on the helicoid of MAF. Sincerely, in hindsight, spend all that money (see on the site how much it costs) for a lens that has all those "characters" and that allows you to photograph only in stop-down because it does not have the automatic transmission of the diaphragm, I only call it a "SOLA". The much-vaunted sharpness, at this point, if there is, I don't care anymore. Next time I'll be more careful. P.S. The same Chinese optics, branded differently, is sold at half the price by a well-known Abruzzo optical-mechanical construction company!! sent on November 11, 2019 |
