As a complete beginner at this game I went out on Friday evening to photograph my grandson playing cricket. I am using a Canon 50D with a Sigma 70mm-200mm f2.8 II APO EX DG Macro coupled to a Sigma 1.4x teleconverter. I managed one or two reasonable shots, bearing in mind my newbie status but found that, apart from not picking the best vantage point in the ground, my lens was proving to be a little on the short side. My question is what do you sports togs use for cricket? I am now thinking along the lines of purchasing one of the following...a Sigma 100-300 f4 or a Sigma 120-300 f2.8, or a Canon 100-400 f4.5-f5.6, or what about a Canon ef 300mm f4 IS USM. Any thoughts that you may have on these lenses, particularly if you use any of them, will be greatly appreciated, as will any recommendation for another lens not mentioned here. Ideally I would prefer to not have to spend more than £1K and am more than happy to purchase second-hand. Thanks in advance of any input.
