It is no secret that one of the best advantages of mirrorless over traditional DSLR systems is the ease of adapting various lenses to your camera. You can use really old vintages lenses for a unique look and feel with ease, but the one thing you always give up when you use these old lenses is Auto Focus – but Fotodiox Pro doesn’t want that to be the case anymore (at least on Sony mirrorless) thanks to their new PRONTO lens adapter.The PRONTO lens adapter does something unique – it allows the camera to communicate with it, and then uses a tiny motor to adjust the position of the lens to achieve focus in the shot. What this means is you can now use your vintage or manual focus only lenses with autofocus! Now, it’s not going to be incredibly fast or accurate AF, and definitely not good for tracking subjects, but if you don’t mind a slightly slower AF experience, this could be a nice lens adapter for you.
But whats more, it’s not limited to just one lens mount. The PRONTO base can be used with several other primary mounts, so you can use this one adapter with Olympus OM, Pentax, Nikon, M42 and more by simply switching out the lens mounting plate. Which makes this an even more interesting idea.
Fotodiox Pro says the adapter works with the Sony camera’s phase detection AF system, so it may be faster than contrast detect based systems, but color us skeptical until we see that work well with our own eyes. Additionally, we do somewhat wonder who could really NEED this sort of adapter – sure, if it was as fast and accurate as a normal Sony lens that would be one thing, but we can be pretty sure that is not the case. So then the question becomes, is this AF going to be faster and more accurate than you with the all of the manual focusing aides Sony cameras have now? That depends on the photographer, but we know from experience that fast and accurate MF is totally possible, so we wonder at what point it would be better to just perfect your MF skills vs invest in an adapter like this.
We guess time will tell. More information about the PRONTO lens mount adapter can be found over on the Fotodiox Pro website, here.
