85mm on APS is 135mm... 135mm on APS is like 216mm..... so 216mm.... even shoot f/2... shutter speed will be challenging... plus cannot bump ISO beyond 400.... so do not think it is ideal...... though I have both..... that's why I did not consider 135mm at all..... for this.....

Considering in an event, where you are busy shooting for hours... by then, the hand usually become very shaky... that's why I did not really consider the 135mm.... the reach could be just too long too......
Of on 5D3... no issue... just bump ISO.... and IQ still is great..........
