I can't set a high frame rate with some lenses.
When certain lenses and recording formats are combined, the maximum frame rate may be restricted.
Operating Instructions, 5. Shooting - Useful Functions - Slow & Quick Motion
The following message is displayed in VF when the maximum frame rate is reached.
----------------------------------
The upper limit of xxx FPS for
the current lens and recording
format has been reached.
----------------------------------
Refer to the lens compatibility information below for more information on lenses with this restriction.
