Pentax HD PENTAX-DA AF Rear Converter 1.4X AW - Thoughts
1

Well after seeing the exif data from a converter attached lens I've placed my order.

Because the lens ID remains intact but the aperture and focal length is corrected this converter should work with all lens (if they physically fit) SDm/HSM/DC etc etc.

even better AF should be 40% faster than the native lens because no longer is there a requirement for a af reducer like old lens so AF will operate at full speed.

Obviously at full speed if a lens required 10 turns to focus 1ft it will now need 6 turns to focus 1ft so 40% faster.

Wonder how long till someone measures end-end travel and states 'your wrong it take the same time' missing the point entirely as all 'end-end' measubators do
