Sony FE 135mm f/1.8 GM Named "Sharpest" Lens Ever Tested by LensRentals

In fact, according to their charts, it's the sharpest lens they've ever tested... out of over 300 units that have been examined.

To help further explain the results, PixelShift VP, David Schloss, has broken down and elaborated on LensRentals' tests and conclusions. CLICK HERE to check out PixelShift's full breakdown and CLICK HERE to check out Roger Cicala's original blog post and charts on LensRentals.

Below are some key takeaways from both articles:

 LensRentals' optical tests are used to create an MTF chart which tracks the resolving power of a lens from the center to the edges. The higher a point is on the graph, the better the resolution is.

 The Sony lens produced the highest MTF in the center that LensRentals has ever encountered on a non-supertelephoto lens.

 The Sigma 135mm f1.8 was previously the sharpest 135mm lens that LensRentals tested, but the Sony GM proved to be "dramatically better" in the center half of the chart.

 The Sony 135mm f/1.8 GM has a higher MTF at 100 lp/mm than most prime lenses have at 50 lp/mm -- which essentially means the Sony is capable of producing fine details that would otherwise appear blurry on many other lenses.  

 The impressive MTF chart results indicate that the Sony lens is not only designed to pair well with current high-res 42MP sensors, but with even higher megapixel sensors in the future.
