Here is a side-by-side look at the specifications:
If you shop around a bit, you will find that the difference in price is only about $50.
Newegg.com shows $305 and $354.
I looked at sample photos from each camera taken of the same scene and the SD400 was better due to its greater detail from the extra megapixel.
I would say, go for the SD400.
Hey there. I am just about to purchase my first new digital camera in 4 years! I was just wondering if i should save some money and go with the SD 300 or pay the extra $100 or so for the SD400. Is there a huge difference between features or picture quality?? I am also considering the Nikon coolpix S1. Thanks a lot in advance!
