Best lenses for the 16-MPix Panasonic Lumix DMC-GX7: Part 1By Kevin Carter - Thursday December 12 2013 Lens Recommendations
The top-performing model on the GX7 is also the most expensive prime in our database, and made not Panasonic but by rival Olympus instead. The 75mm short tele has a stellar reputation and is the equivalent of a 150mm. With an f1.8 maximum aperture it’s a promising option for low light venues, indoors sports and action, as well as outdoor portraits. Although large for a MFT format lens it’s still compact with an overall length of 69mm. Wide-open on the GX7 it’s not too sharp for portraits but sharpness improves when stopped down.
In second place is another highly respected if also somewhat expensive model, the fast standard Leica 25mm Summilux. It has very fast focusing and it’s sharp centrally from f2.0 onwards.
In third place is another highly regarded optic, the Olympus 45mm f1.8. Like the 75mm on the GX7 it has a good sharpness when stopped down from the maximum aperture. With a useful 0.5m closest focusing distance, it’s a highly attractive option for portraits. At a reasonably modest $239, Sigma’s 60mm f2.8 is another tempting alternative.
As a high speed standard, Panasonic’s upgraded 20mm f1.7 ‘pancake’ lens is another excellent performer and a popular choice. It has similar peak sharpness to the Leica 25mm ‘lux’ while being both smaller and more modestly priced. As the equivalent to a 24mm, the Olympus 12mm f2.0 is the best performing wide-angle lens in the group with a DxOMark score of 17 points and a 6P-Mpix peak sharpness.
