A Doh! Moment

August 15, 2013  •  Leave a Comment

I recently had one of those Doh! moments where I can't believe I never thought of something before.

Of the three lenses I have, I have always been a little less than pleased with my Tamron 17-50mm leans, particularly since I upgraded to my 7D camera body. The biggest issue I had was regarding sharpness; the Tamron always seemed softer than my two Canon lenses.

As I was perusing the web, I came across the term Micro Focus Adjustment (MFA). What this essentially means is that because each lens and camera body is unique, a particular combination may require some adjusting to work together in an optimal fashion, in this case regarding auto focus. In order to calibrate a particular lens/body combination, one uses an image (like the one featured as the cover of this post) of co-centric circles to compare focus. When I did this I learned that my Tamron lens was WAY off and needed to be adjusted significantly. So hopefully that will help fix my softness issue with that lens. Time to get out there and take some more photos!
