Lens Sharpness Comparison

Sony 50mm F1.8 vs Sony RX100 2's Lens

Sharpness at 50mm.
Tested Apertures F4/F4.5, F6.3/F8
 
Comparison by Sinan Ozturk   
Sony 50 F1.8 (on Sony Alpha A35) zoomed at 50mm.

Sony RX100 2 (fixed lens) zoomed to same focal length. At this focal length Sony RX100 2's maximum aperture is F4.5 so in the comparison Sony 50mm F1.8 is also stopped down to F4.

In the second comparison both lenses' sweet spot is used which is F8 for Sony 50mm and F6.3 for Sony RX100 2. So second photos are their best performance.
