I have this desire to get up close and personal so I need to step back. I keep forgetting that this is a 50mm lens. I think the reason I'm finding it difficult to focus is because I'm too close to my subject. Lensbaby offers a Macro Converter or a 46mm Macro Filter Kit. I may consider this down the road, but I still have a lot to learn. I read that the macro filters are easy to pop on and off and might be more versatile. Before I buy anything else I may try using an extension tube or two. Since I'm also considering a macro lens down the road I want to be sure I'm going to get the results that I expect. I will probably want a more versatile lens than this Lensbaby Sweet 50.
The two images below were cropped for better composition. I had pretty good morning overcast light and shot these at f5.6 early this morning.
I think I could have gotten this shot with my 50mm prime lens so I'll do some experimenting. Below is the full image, before cropping.
