I succumbed to an impulse purchase just minutes ago... The Marine Corps Exchange had a perfectly good Canon EF 75-300mm f/4-5.6 III on the clearance shelf for $161.99 (tax free!) Seeing as I've been desiring a new lens for a while now because the kit lens just doesn't satisfy my desires so, I bought it. Anyways, I've already done test shots to see the capabilities and compare them to my 18-55mm. Here are the test shots - Flickr: srinaldo86's Photostream Should I return this lens and save for a more expensive one? I'm no professional so the quality is about what I expect to get for the money.
