Use with older lenses

While SB is primarily designed for use with Canon EF lenses, where can ensure the transfer of information to the EXIF ​​and (sometimes) slow autofocus, this is just the beginning. Its great potential lies mainly in the possibility to use older lenses from different manufacturers.

Works!

After a long wait Speed ​​Booster arrived from England. It works perfectly! For those who can't wait I have the first photo with the lens Canon 50 mm f1.4. Click on the photo to get scaled-down version of the original with the EXIF ​​information as recorded by SB.
