Brian, I would say just check your set up for any focus issues with each lens and micro adjust them if you need to. Then I always shoot on spot metering and spot focus with single focus servo. Camera set up is the most important thing with taking great images. In all my workshops it is the first thing we go over because almost everyones camera isn't set up for taking the best shots.

Thanks Zak !
...sorry for being dumb!!, but what is 'micro adjust' and how's it done!?!?
Bri...
Thanks Zak for introducing the subject of fine tuning our lenses, do you use the fixture mentioned in this article: Lens Align Pro Review. Focus on Better Focus: How to Micro Adjust your camera.
There is many ways people say to do it and some say you can't Micro Adjust variable lenses only prime. What I find is that if I am adjusting say my 18-200mm lens is that if it front focuses at 18mm it rear focuses at 200mm. What I do is set my lens at mid point say 110mm and micro adjust it there which evens out the lens correcting both ends to the best of its ability.
