different tools for different applications

I like to spend time on flickr.  It is an amazingly diverse community of photographers ranging from absolute novices to consummate professionals.  One of the questions that come up in the gear groups there and in conversation with other photographers quite often is, “which lens should I purchase?”  With interchangeable lens system cameras coming down in price by the day it seems, it is becoming much more accessible to acquire high quality photographic tools.  One of the main benefits to an interchangeable lens camera, is just that, lenses!  Which to choose and why?  C’mon in and we shall discuss.  Before the end of this article, you too will know which lenses will provide you with the best bang for you buck, depending on which buck you choose to bang… Continue reading →
