I am looking to purchase a lens for 50:50 macro:portrait, the portrait will mainly be of my 2 year old so the focus needs to be fast (as it can be on a macro) and accurate. Will i notice much difference indoor/low light and boken between F2 vs F2.8.
I have read the focus ring is stiff on the Tamron and that AF tends to hunt alot? Which has the smoothest bokeh especially for those portraits. Canon has usm vs tamron F2. I have heard great thing about macro from both these lenses but I would love to hear about portrait too.
Has anyone compared the 2 lenses? how do they compare portrait wise to the 50 1.8/1.4?
I know working length for macro is ideally longer but i can't afford 2 lenses and ltd space indoors for 100mm.
Any help advice welcome
