>>3764444Oh my God, look at the tasteful thickness of my quads. I know checking one's own digits is poor etiquette but damn.
>>3764446Those are expensive because of being superzooms but won't give you amazing picture quality. They're versatile in that they can take both wide and long pictures. If you have them at hand take a look at the full names.
Look for things like OSS (optical image stabilization), HSM (hypersonic motor) and EX (means high end, similar to Canon's L) as well as the f-number (example, f/3.5-6.3) on the Sigma. Look for the f-number and any other info on the Canon. It will be either on the ring around the front element or the barrel near the controls. Look for switches on the barrel too, usually AF/MF and stabilization on/off.
I presume the quality will be less than stellar on either, though (because of the massive zoom). Canon is likely better but that can vary.
