Optically, the 35/3.5 macro is excellent and gives a true 1:1 (the 50/2 is 1:2). As noted by others focus is slow but it's a heck of a bargain for what it delivers. FWIW it is one of a handful of Oly 4/3 lenses that are CDAF-enabled, meaning you don't necessarily need an E-M1. Same goes for the Mkii edition of the 14-54. Either version is a good, fast standard zoom but only the Mkii will focus decently on all m4/3 bodies.

The information for the 14-54 is correct but not for the 35/3.5.  The 35 is an older lens that is not CDAF enabled.  It will focus but it will be slow.  I haven't used it on my G3 so I don't know how slow (still have a good 4/3 body to use it on).

This chart shows lens compatibility for the GX7:

Only those with an 'OK' in the fifth column from the left have fast focus capability on the GX7.  The others will work, but slowly, and in one instance, manual focus is needed.
