Hi, a couple months ago i got my first D-SLR camera finally. I ending up getting the canon rebel T2i, with both the 18-55mm lens and 55-250mm lenses. I really like the camera, seems really nice. A question i have is should i always take photos on the highest 18MP resolution? I notice when i take photos, it takes a long time to put them in my computer, and thats only taken about 200-300 at events. I put it in the medium mode, i think its about 8MP, and they downloaded rather quickly like my P&S camera did with 12MP. I didnt see much of a difference in the photos and am thinking ahead for wdw, where i will probably take about 2000 shots when we go, it would take all day if on full 18 MP to get into the computer it seems. I am using 16MB class 10 cards-have 2 of them. Also, i find mainly using the 18-55 lens most of the time, is that correct? sometimes i do want to use the more telephoto, but then i have to change out for just a few shots then put the other one back on. Lastly, i bought a sun shield for the end of the lens, but i noticed if all the way back at 18MM or 55MM on the zoom lens, i can see it in the corners, so i bought a different one that is smaller and that seems to not show up, but is the longer one better to keep the sun out? any other help for this newbie would be great!! Thanks!
