Excerpt: I use a Nikon D7000, but wanted a small portable to carry in my pocket to replace an old Canon SD850IS that was no longer working. I bought two of the Elph 310HS cameras, one for me and one for my daughter. The cameras were only a few days old when I first started taking photos with my 310HS, but I immediately noticed a strong yellow-green tint throughout all of the photos. I then took the same photo subjects with my daughter's new 310HS.
Summary: Unfortunately, this wonderful camera is marred with one main fault, it is designed to have some of the best optics for its truly small size, this is wonderful, however, the engineering of the mechanical components no longer meets the high standards that Canons have been known for in the past. I am satisfied with Canon's warrantee service, but it should be sturdier, given the price... and...
Pros: Wonderful pictures in nearly any conditions as well as great warranty service, that was unfortunately necessary when lens stuck at full zoom. The size is
Cons: It is super fragile. I am rather careful with almost everything I own, however, the camera 'turned on' and extended lens while in small camera case. Luckily explained this to tech dept. at Canon... and they agreed that it should have had a safety mechanism to stop it from doing this, because it jammed the zoom mechanism. Replaced free... but still has no safety mechanism to prevent this.
