<p>For sure you should keep it, a $100 dollar lens that can produce outstanding results. I recently took a panoramic of the Detroit skyline at night with this lens. I shot it with 2 different lenses. 1 attempt with the 50mm f/1.8 and another with a Canon 28-135 f3.5/5.6 IS @ 50mm. My reason for doing this was similar to yours - shall i sell it? <br>

The answer - NO WAY!<br>

The results from the 50mm were far superior in my opinion compared to the same shots taken with the 28-135 @ 50mm. The sharpness and level of detail was outstanding.<br>

I have not post processed the results from the 28-135 but you can see the results of the 50mm in my portfolio. I obviously cannot compare it with results you can achieve from the Tamron, but you should try the test. Same settings on your camera in same light at various apertures. </p>

<p>Try going to Costco. On their website they have link and tips to calibrating your monitor and downloading the printer profiles for the store you are using to ensure that what you see on the screen is what you get!</p>
