I guess I should start with introductions. Hello! I got into DSLR photography 3 years ago and because my day-job revolves around moving images, it has been more of a nice hobby than a career move (though it's a pretty complimentary one!) I still use the same 300D and I've gradually been collecting lenses for it. Currently I have the kit lens (now in storage), a Sigma 17-70, Canon 75-300 (it's slow at 4-5.6 but it has IS which is nice) and my two special lenses, a Sigma 105mm macro and the Sigma 8mm fisheye. These last two I guess are my guilty purchases. I bought the macro about a year and a half ago, and besides having fun with it, I've not had too many practical needs for it! I think I've used it for 1 session of product shots, and the only other time I break it out is when I need a faster long lens normally for indoor stuff (its 2.8) The fisheye I only bought this week and I've not had real chance to break it in yet. I shoot a lot of band videos and can get very close up to sporting events so I can at least see me getting more use out of this lens at least. Not to mention the easier panoramic photography. The question is, should I feel bad about not using the lenses much? How should I find more use for the macro? Also, what about less cliché uses for a fisheye? I guess having spare lenses around you only break out when you need to isn't a bad thing, but if I really decide I don't need the macro for example, I could probably sell it and put the money towards a new body. What do you think?
