Im not an expert in cameras to tell anything technical about it. But Ive been using a A550 for the past one year and Im very much satisfied with it. I should say that this camera taught me how to take better photos. I say this stressing on th ease of handling it.
The manual that came with it was of not much use and hence had to teach myself into using it. Now with a little help from my girl friend and a little knowledge of photo enhancing softwares, I manage to take some really good shots. To know how good is this camera you can visit https://flickr.com/photos/sambhusankar/ and see for urself what really can be expected of this camera. I sure have done a bit of touch ups for the photos but yet the original should be good enough for touch ups right?
I dont find anything particularly wrong with this camera. As Ive told you before, Im 100% satisfied with it.
