Lens Sharpness Comparison
Sony 50mm 1.8 vs. Tamron 17-50
Sharpness at 50mm. Tested Apertures F1.8/F2.8, F2.8, F4.5, F8
	Comparison by Sinan Ozturk

In the first photos, lenses were compared with their largest apertures which is F1.8 for Sony 50mm and F2.8 for Tamron 17-50. Both lenses has some vignetting but Sony 50mm's vignetting is pretty heavy as you can see. Their center sharpness are close to each other at these apertures, yet in the corners Tamron is a little bit sharper.

When we stop Sony to F2.8 in the second comparison, its vignetting improves and now Tamron has more vignetting in the corners. Their sharpness performances are close to eachother but Sony 50mm looked a little more sharper to me especially in the center.

When they are stopped down to F4.5, both lenses cure their vignetting problems. Their sharpness are also good and close to eachother but then again Sony 50mm seems to have a very small edge in the sharpness performance. Yet considering its a prime lens and Tamron is a zoom lens, in my opinion Tamron is still coping with it very well.

At F8 Tamron reaches its peak performance and gains a little more contrast. They sharpness performance are again very close and maybe even same. But with the gained contrast Tamron looks just a tad sharper at F8 both in the corners and center. [Review by Sinan Ozturk]
