This uniform appears to me to be an army uniform, not an SS uniform.
The cap is the standard issue officers' cap, lacking the SS Death's Head emblem.
The collar double tramline effect is the army officers' designator. The SS used a variety of collar emblems used separately or inter-mixed. These were, :
Square stud effect, in a variety of layouts and numbers
SS lightning emblem
Variety of different laurel wreath layouts
All of this are absent in this picture. Unfortunately the exact rank is shown on the shoulder flashes and I can't make them out at all.
The only thing I can tell you about his medal ribbons is the one in the second picture that is wrapped from the button to behind the tunic. This appears to be the War Merit Cross Second Class. The Iron Cross Second Class ribbon is similar, but the colours were reversed. The ribbon pictured here has a dark (black) central stripe and lighter (red) outer stripes.
Presuming this is the same individual, the second picture is probably taken later as the first one lacks the ribbon.
