Stupid me, took the Tamron lens to Africa without actually getting acquainted with it first.
First, it zooms the wrong way. Not like Canons do.
Second, it is quite long and heavy and does not fit in my regular camera cases.
Third, the animals get worried when this thing is pointed at them and they seek cover.
Other than that, I fount the picture quality up to 400mm OK full open and 600mm acceptable at f/8.
You have to use manual focus every now and then which is not a surprise. AE seems to have some issues as well, especially shooting against the light. Compensate according to the histogram.
