Tamron 70-300 f4/5.6 DI VC USD & Kenko Teleconverter - April 12 2012

Tamron 70-300 f4/5.6 DI VC USD
Went out again today this time without the teleconverter.
I actually found the AF was much more precise without the TC, particularly when trying to get a photo of a bird in amongst the clutter of branches. I've found that that light affects the TC more so than I had originally thought. It seems to work best in bright sunlight.
Here are some pictures from today's outing.
The two Robin photos were taken about the same time of day at about the same distance, (aprox 25 feet), on two different days, one with the TC and one without.

 Song Sparrow 20 feet
Tree Sparow 30 feet
This sparrow had just flown up from having a bath in the river and was drying off in the sun.
I think we will try the 1.4x TC on Rose's Canon 100mm F2.8 lens next.
