There is great interest in using third-party lenses on some modern digitals, particularly mirrorless offerings from the likes of Sony and Fuji. Leica M lenses are the iconic choice but there are endless permutations of lenses and cameras. All this is possible by using lens adapters to convert mounts to work with other manufacturers’ lenses. I have written about my experiences with adapters such as the Voigtländer Close-Focus device for Sony A7s and the Metabones Leica R to Sony E mount but that only touches the surface.
Such is the interest that the choices multiply by the month. But is a £15 adaptor from an obscure eBay supplier as good as a German Novoflex or a Canadian Metabones? Or should we stick to the expensive adapters offered by the camera manufacturers themselves. Now we have some sort of answer in an exhaustive article by Brian Smith who has analysed all adapters for the popular Sony A7 range. Of course, using adapters brings compromise, as GServo reminds us at The Phoblographer.
