As you may have realized from my previous blog posts am i a huge fan of old vintage lenses. This love has grown so strong that I decided to completely switch from Sony A-Mount to Sony E-Mount. I sold my A77II, which I enjoyed for the past 2 years. But after I bought the A6000, the 77II found its place in my cupboard.
The reason for this step from A to E is the way shorter flange focal distance of an E-Mount Camera. The flange focal distance describes the distance between the last (rear) glass element of the lens and the sensor or film of the camera. As you can see in
the picture the flange focal distance of a conventional A-Mount (or any other camera with a mirror or translucent mirror) is way longer. The mirror and the flipping mechanism need space.
Flange focal distance
In this list, you can see the flange focal distance of several mounts (Full list can be found here). I personally use Minolta MD, Minolta A, M42 and Exakta EXA on my Sony Alpha 6000. If you want to adapt old or just different lens mounts to your camera without any effect to the infinity focus or the quality its important to always keep an eye on the flange focal distances. If the distance of the lens you want to adapt is at least 1mm longer than the one you need on your camera you may be able to find an adapter in the WWW.
| Sony E-Mount / Sony NEX | 18 mm |
| Sony A-Mount / Minolta A-Mount | 44,5 mm |
| M42 x 1 | 45,46 mm |
| Exakta EXA | 44,7 mm |
| Minolta MD / MC / SR | 43,5 mm |
| Pentax Q-Mount | 9,2 mm |
Some examples:
“I want to adapt a M42 lens to my Sony E-Mount Camera” à No problem. Look for an M42 to E-Mount adapter. Have fun.
“I want to adapt a M42 lens to my Sony A-Mount Camera” à Maybe a little problem. There are really thin adapters to buy. Make sure to buy a “good” one that has the exact measurements. Otherwise when it’s a little bit too thick or too thin you lose your infinity focus.
“I want to adapt an Exakta EXA lens to my Sony A-Mount Camrea” à There is no way to adapt the EXA Lens to A-Mount without either losing infinity focus or dealing with an extra lens inside the adapter. It’s possible but you either lose quality and light or the infinity focus.
“I want to adapt an Exakta EXA lens to my Sony E-Mount Camera” à No problem. Look for an EXA to E-Mount adapter. Have fun.
“I want to adapt a Pentax Q-Mount lens to my Sony E-Mount Camera” à There is no way to adapt the Q-Mount Lens to A-Mount without either losing infinity focus or dealing with an extra lens inside the adapter. It’s possible but you either lose quality and light or the infinity focus.
As you can see in the examples it’s always possible to adapt a lens. The only thing you might lose is quality and light or infinity focus. There are even some “smart adapters” which you can use to use autofocus lenses (Nikon, Canon) on your Sony E-Mount Camera. (Need to be the newer models to deal with the autofocus).
