The photo is too big, so I open it and take a screenshot of it so I can uploaded here.
Anyway, if you look close, you can tell this bird is not properly focused. That's a very common problem with my setup.
First of all, the auto focus from Samsung is absolutely shit. Everytime it focuses on a branch either behind or in front of the bird. It always failed to focus on the bird itself. So I use manual focus. But then the screen is very small, with direct sunlight, I can't tell if the bird is crystal clear or not. I placed an order from fuji to see if it looks better on a 4R photo paper. But even if it looks ok, I still want to try if I can get a perfect focus with my phone.
One possible way to solve it is to carry a HDMI screen. Samsung's camera app can output a HDMI preview when connected to an external monitor. But I wonder how I'm gonna take a picture of bird with such chunky devices.
