I have been on holiday in Canada for two weeks, walking with my Tamron 150-600mm and 5DIII. The birds are difficult to find - you suddenly come across small birds who will be around for a few seconds or minutes and then disappear. To get any photos you need a portable, reasonably long lens that you can swing into action in seconds. The birds are often hiding in bushes and you need IS for long exposures. My 300mm f/2.8 II + 2xTC III would have been the best solution, but the Tamron 150-600mm was more than good enough and more suitable for a holiday combining a family visit with the odd day for birding. Those knockers who have dismissed the Tamron in favour of a 400mm f/5.6L + 1.4xTC would have been completely stranded without IS - one of the exposures was as low as 1/50s and many in the 1/250 range. The 100-400mm would have been too short. The exifs are on the photos, which are all 100% crops, ie 1 pixel on the image = 1 pixel on the uncropped full frame. I was pleased with the haul. Most of the photos were in the Hammonds Plain area of Halifax NS.
The first 4: Canada Warbler 1/50s, Cedar waxwing, Black-capped chickadee, Ovenbird.
