EOS 500D (美版为Rebel T1i), 裸机$799. 不过现在裸机供货不足,似乎还需要等等,也望可以盼到降价.
features: same 15.1 Megapixels as the semi-pro EOS 50D; DIGIC 4 models, faster processing and better noise reduction at high ISO;
               ISO 100-12800 (though I don't think I would touch anything beyond 600 or so);
               recording: 720p at 30fps, 1080p at 20fps (gonna take up a lot of my intended 8G SD)
               anything else I didn't/ need to mention?

Canon EF 50mm f/1.8 II Standard & Medium Lens (定焦50mm, 1.8), $89. Should I take this or not?

One of the more popular and inexpensive prime lens with an amazing f/1.8. Said to be high quality for the price, but slow/noisy autofocusing. Any other thoughts, people?


Tamron AF 18-250mm F/3.5-6.3 Di-II LD Aspherical (IF) Macro Zoom Lens for Canon, $449.
More expensive than I thought, but the wide zoom is irresistible. Thoughts, guys?

Or


Canon EF-S 55-250mm f/4.0-5.6 IS Telephoto Zoom Lens, $253. Sacrifice the 18-55 zoom and smaller aperture at a lower cost, this one may not be a good travel/walkabout one. Thoughts, guys?

or

Canon EF 28-135mm f/3.5-5.6 IS USM Standard Zoom Lens, $398. Finally one with USM, good for general purposes and walkabout but at the expense of a tele-size zoom. A little bit cheaper than the Tamaron one. Opinion?
