I have never had pleasing results with the 135/2.8 AI-S in infrared but decided to give it some cencentrated camera time in order to 'learn' by touch how to overcome the horrific IR focus shift that this lens exhibits. Up close is easier than at infinity (maybe that is due to my copy of the lens). A non-IBIS D610, handheld, using live-view at 135mm in a fast, crowded and brightly lit environment was not going to work. These life-sized guys were static but getting a non-obstructed view at distance was a challenge.
