SQL - select the record with the highest count value within a field

is there a way to select the first record with the highest count value
within a field?
 
Example:
Data: 
FIELD1   FIELD2    COUNTFIELD 
AAA      A12        5
AAA      A13        2
AAA      A14        1
BBB      B17        5  
BBB      B13        5
BBB      B15        1

Result needed (Assuming FIELD1 is the field where the highest COUNTFIELD
need to select from)
FIELD1   FIELD2    COUNTFIELD 
AAA      A12        5
BBB      B17        5
