“While photographing a moving subject, how can I better improve my skills and/or what photographic equipment(s) I shall look into, to achieve crisp and sharp images?”

“I enjoy doing sports photography that has a lot of action – what are my options for capturing fast action and stop action? I enjoy shooting both indoors and outdoors? Does this mean I should change lenses? Is there one lens or should I be looking at some choices? Are there options for filters that I should also consider?”

Currently I have a Canon 60D and a Sigma 18-250mm all in one lens. Love this lens for its versatility from Macro to zoom. I’m now looking into my next lens. Can you suggest my next lens? I’m more [interested in] people photography and at times, landscapes.

Everyone keeps telling me to get a prime lens, but it seems limiting to not have the ability to zoom. What benefit will I see from a prime lens? Do the pros use prime lenses or zoom lenses?
