Hi, I'm really enjoying this forum and learning so much. Thanks to all for sharing your knowledge and experiences. After using a Canon ELPH for the last several years, I recently ordered my first DSLR-- a Canon Xsi/450D with the 18-55 IS kit lens plus a 55-250 IS lens, along with an 8GB SDHC memory card. In addition to that, what would you recommend I get right off the bat to complement/protect my investment? Should I go ahead and get UV and circular polorizer filters as protection and image enhancement? If so, what size? Will HOYA multi-coated be OK or overkill for a beginner? I'm sure I'll eventually want some kind of bag to carry my gear in, but that's so personalized I figured it'd be clear what my needs are after owning the camera for a while. My heart is already set on eventually picking up the nifty-fifty prime lens and one of the Speedlites, but I want to spend some time becoming proficient with what I've already ordered first; not to mention that I cannot afford everything I want yet. Is there anything else you'd recommend I consider getting early on? Right now, I expect my uses to vary, since I am new to this and haven't established my special interest. I will take pictures indoors of family, outdoors at social events/concerts, my son's sports, and landscapes/wildlife. Thanks in advance for your advice.
