I recently purchased the Tamron 18-400mm F/3.5-6.3 Di II VC HLD lens for my canon. I tested it using the SL1 and 7D that has the cropped sensor. I was amazed with the result and it’s truly at 22.2x zoom.
The images above are not processed, no correction, without any filter, etc. This is just a demonstration of the zoom capability of the lens. All shots are handheld with only the VC turned On.
