Shutter speed is a factor also when shooting under common fluorescent lighting. At higher shutter speeds, color banding and exposure inconsistencies become an issue. I just get Mark III and EF 24-105 1:4 L IS USM lens and went for important indoor presentation with combination of tungsten and fluorescent lights. The original Canon EF 24-70mm f/2.8 L is sharpest at the plane of focus at 24mm and f/2.8 when tested on a Canon 5D Mark II. Stopping down yields very little increase in center sharpness and results in slightly softer mid-frames and corners (at the absolute point of focus .). As you move from 24mm to 70mm the edges get progressively softer. Outdoor on a sunny day it is easy to get a proper exposure because you have so much light. I would try Av mode (aperture priority) and select as Tim suggests, a wide-ish aperture like f/4 and a focal length between 50mm and like 80mm on your T3i. The shutter speed will be very fast and that is great. 1. I just received my Canon 5DS (the international version) in the mail today. I upgraded from a 6D, and the first thing I noticed is that the default setting on the 5DS was to only display 1 focus point, in the center. The 6D had all 12 points showing. When auto focusing with the 6D, many different points would light up and the one it focused Overall image sensor performance. The Canon 6D Mark II’s new 26.2Mp full-frame CMOS sensor delivers very good overall performance, achieving a DxOMark sensor score of 85 points to rank as the 5 th best Canon sensor we’ve tested. Its stand out performance is in the Sports ( Low-Light ISO) category, where a very good score of ISO 2862 ensures They include settings for fixing the very abrupt highlight rolloff on the 5D Mark III in video mode, by shifting the usable dynamic range of the camera towards the highs, without compromising noise in the lows or shadow detail. In fact it allows you to expose for the lows without worrying as much about blown highlights. 1.
