Just picked up a Canon T6s for our trip to India which we just did. Got it with the standard 18-135 lens which was great for the trip but won't be good for the next event...kids opening presents in "lower light". The high F number of the 18-135 lens is already showing its limit and almost forces the need for a flash (kids don't sit still for longer exposure). Any recommendation for a good low light lens? Some in the F1.8 or better is a target. Have a budget of ~$200 but will spend more if makes senses Second..there is the book most of you keep recommending on the basics of photography. usually it is a link from Amazon and the book isn't that expensive. I would really like to get off the "full auto" modes if possible and I think it should help.
