Hi, I have a 85 1.8 lens and want to do portraits with it. Compared to that lens I want one that is sharper and with more limited depth. Would the 85 1.4 help much or is a longer lens required? I have looked into the 200/2 but its a expensive lens, how does it compare to if one headed to 6x6 or 6x7 MF? I want it to be sharp so that in normal length framing I get limited depth and I want it sharp enough that you are able to see skin pores and individual strands of hair and eyebrows. Print size is probably gonna be A4 most common but I want detail and bokeh. Thanks.
