AF speed of the PZ1650 vs SEL35F18

Was able to do a side by side comparison to the AF speed of the PZ1650 vs SEL35F18.

(Note that the PZ1650 support Phase Detect AF while the SEL35F18 only works on Contrast Detect 'at the moment'. I have 2 Nex 5R both set at the same setting)

Test Condition:
-Test took place indoors in low light. Auto-ISO will set from 1600 to 3200.
-Random panning from a close subject, mid distant subject, to a far distant subject.
-I held the two Nex 5R. One on each hand, vertically. occasionally switching cameras from one hand to the other.

Sony NEX SEL50F18 Versus SEL35F18

We have the likes of SEL50F18 and the SEL35F18, which by all measures are and will be good enough, heck, better than enough. And they are affordable by a much larger majority of users. 

Which one you would recommend SEL35F18 or SEL50F18?
