Lens Sharpness Comparison
Tamron 17-50 vs Sony RX100 2's Lens
Sharpness at 50mm. Tested Apertures F4/F4.5, F6.3/F8
	Comparison by Sinan Ozturk

Tamron 17-50 (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 Tamron 17-50 is also stopped down to F4.

In the second comparison both lenses' sweet spot is used which is F8 for Tamron 17-50 and F6.3 for Sony RX100 2. So second photos are their best performance.
