Re: EF 70-300mm f4-5.6 is USM II

thanks for the input, think I figured out what has been hindering my shooting.

1)  first several days was shooting in overcast weather

2)  had filter affixed to lens

yesterday had a sunny day & took off filter, great experience, lots of keepers.

filter added more glass to shoot through and I guess overcast day hindered contrast for AF to work properly

looks like alls good
