Members of the dpreview Canon forum are finding "hidden" gems and lumps of coal. I've also found some from digging through the feature list and photos of the new S2is:
- separate button needed for supermacro mode
- when taking a still during movie mode, the still is 5-megapixel, but there is a blip in the video
- this camera does not have a remote (but then the S1's never worked properly).
- custom time for duration of delay and number of shots taken (my daughter's Casio takes 1 or 3 self-timer shots)
- use camera as audio recorder, up to 2-hour recordings (no use to me)
- color modes and custom scenes -- not sure the utility of these
- camera is a half-inch thicker, which may make it hard to pocket
- no hotshoe, but an optional USB-connect flash available
- LCD screen is still unreasonably small
- While high-speed shooting mode is 2.4 shots/sec, the normal speed is still only 1.5 shots/sec. for photos in Large-Fine mode.
- Night Display brightens the display by reducing LCD screen's frame rate -- leads to jerky viewing, if that's like my Canon camcorder night mode.
Another problem for those hoping to reuse their S1 accessories with the S2: the filter size is larger: the S1 teleconverter has a 52mm thread, but the S2 is 58 mm. A stepdown adapter might cause vigenetting.
Amazon.com's ship date for the S2 is July 5.
