Shoot during high pressure (clearer atmosphere), when there is no wind, and when there is no day time heat that may be causing optical issues. Shoot when the moon is high - the lower the moon is, the more atmosphere you have to shoot through, which can affect the sharpness. Use live view to focus.
The Canon 50mm f/1.8 STM is optically superb and handles very well. It has exactly the same superior optics as the EF 50mm f/1.8 II, which had the same optics and added multicoating to the optics of the EF 50mm f/1.8 of 1987. Autofocus performance top. Autofocus is fast and nearly silent, as we take for granted with Canon.
At f/1.8, the Tamron is more than sharp enough for portraiture and the level of sharpness is consistent across the whole frame. Bokeh is wonderfully smooth, even more so than with the Tamron SP 45mm f/1.8 Di VC USD, helped by the longer focal length. 4. Canon EF 85mm f/1.8 USM. The best Canon DSLR portrait lens for size and price.
For Canon 5D Mark II: in LiveView, with movie recording enabled AND LiveView display set to Movie. Tip: you can change LiveView display type from Expo menu. For Canon 50D: in LiveView, with movie recording enabled from ML menu.
