Here in Australia, the price of both are similar if you are going to buy a quality f1.2 legacy lens to go with the speedbooster. On paper, the 2 choices have similarities in that you will have manual focus lenses and f0.95 (or thereabouts) aperture, once the speedbooster increases the aperture of the legacy lens. The obvious advantage of going the Metabones route is that you can get more cheaper legacy lenses, whereas with the Nokton, it’s specifically made for the M43 mount. But what about the experience/ease of use and above all, image quality? Let’s make the following assumptions: - The legacy glass I’m talking about here will have an f1.2 aperture, such as Minolta MC Rokkor 58mm/MD Rokkor 50mm or Canon FD 55mm or Zuiko OM 50mm. In other words, quality lenses which will cost a bit more than most other legacy lenses which you can buy. Similar f1.4 legacy glass will of course also increase to f1 with the speedbooster. - The legacy glass will be in as good condition as can be expected. I know this’ll be easier said than done considering the age of the legacy lenses, but let’s assume anyway. - We’re talking about still images here - not interested in video. So does anyone have experience of both and if so, any opinion on the quality of images produced? It’s going to be one or the other for me, any comments or advice here would be greatly appreciated.
