Just to add a little more to what the guys have already said:
the white Jungstammführer
lanyard accompanied by HJ-style shoulder straps and the lower rank puts a date on the photo of 1939 at the earliest because in that year the lanyard ceased to show the wearer's rank and instead showed his appointment. This explains the disparity between the lanyard and the actual rank shown on his shoulder straps.
(The photo seems a little over-exposed so it
might be showing a green lanyard although I strongly doubt that. Nevertheless, even if that is the case his HJ-style shoulder straps give us an absolute earliest possible date as being 1938 as Darin says)
The Traditionsarmdreieck and lack of
HJ Ehrenzeichen shows that he joined the DJ during the four months between the 2nd of October 1932 (qualification date for the HJ Ehrenzeichen) and the 30th of Jan 1933 (qualification date for the Traditionsarmdreieck).
The second pattern DJ membership badge he is wearing was not actually permitted at this point because it had been superceded by the HJ Ehrenzeichen. The DJ badge was however permitted for wear on civilian clothing. He is probably wearing it because he didn't qualify for the HJ Ehrenzeichen but still wants to show that he was a member of the DJ for a few months prior to the qualification date for the Traditionsarmdreieck. A possibility is that he had applied for, but not yet received, his HJ Ehrenzeichen and that this is the reason for the DJ badge being worn. I have my doubts though because by the time this picture was taken he had had close to 5 years to apply for the HJ Ehrenzeichen.
The NSDAP membership badge shows that he was at least 18 years old when the photo was taken which in turn means that he must have been 11 when he joined the DJ in 1932.
