These two cameras look very similar and have very similar specs, so which should you buy? Both offer 12MP and are almost exactly the same in every respect except -

Canon Elph 100 HS	Canon Elph 300 HS
Screen Size 3″, 4x zoom(28-112mm), Mono audio recording	Screen Size 2.7″, 5x zoom(24-120mm), Stereo audio recording
Buy from Amazon	Buy from Amazon

Yep – those three specs, screen size, focal length range and audio recording during video are the only noticeable differences. Which one is best for you? Currently the 300 HS is selling at $149 and the 100 HS is selling for $129, depending on the color you pick.   For $20 more bucks you get those extra features of the 300 and the stereo audio alone is worth it!   Note that these two cameras are nearly identical in size – the images above are not to scale and make the 100 HS  look a bit smaller than the 300.  In Reality both of these cameras are in the ultracompact P&S category and are quite small.   A great soft case for either is the Case Logic TBC-302 I also recommend a spare battery and of course an SD Card 8GB is fine   As Always find me on twitter or Facebook if you have any questions.
