Yes I always look for the green dot. I have even taken pictures of books with words and there will be a small part that is in focus but never the whole line of text.

For reference, this is a picture I took using the lens and it is bang on sharp (in my opinion) but it was at f3.5 which I don't have as many problems with.


But for every 100 pictures I take there is only 1 or 2 that are sharp and it seems like a waste of time.
If you can get part of a line of text in a book sharp, and the rest of the text blurred - that's excellent!

It sounds like you're experiencing depth of field, not focusing troubles.

The razor thin depth of field up close with a 50mm 1.8 isn't a bad thing - it's one of the great things about this lens.

As you stop down the lens, or shoot from a longer distance to your subject you depth of field gets greater. Experience will soon help you decide how much depth of field you want in a shot.

This is why the 50mm lens is such a great creative tool - you have absolute control.

I suggest rejoice in your new-found friend, and get lots of practice in with it.



Please note: A 50mm lens with built in focusing motor will not help you with this. Learning how to use depth of field has nothing to do with autofocusing ability Vs manual focusing. Actually - I think manual focusing is even better when learning this stuff.
