It's not even easy to take a picture of a cat with this precision. You made a really nice job. The cat is in a good pose and seems like a model whom you told where to stay and in which position.
, I don't have this problem but when it's really dark like for this picture, I use my most shinny lens which is manual so I'm thinking in buying an automatic one
You can do it, but for me it's a waste of money and time. It's better to use a mechanical one and buy different lens, maybe a MacroS one. When I'll get my external hard drive I'll post you my older photos, and please, feel free to comment and even insult me if you don't like them xDD
