Point of Focus

[theantiquetiger]

OK, I am just starting from the beginning again. I am not worried about anything but the point of focus. When I upload my images to my computer, I notice my point of focus is off just a little. Here are a couple simple shots just around the house. I was practicing focusing on the texture in the subjects. They look in focus in the viewfinder, but just off when I see it enlarged. I do wear glasses. Are these affecting my focus?

In AF, your glasses or the diopter adjustment will only effect what you see, not what the camera captures. To help find the problem source you really need to eliminate the variables which in most cases is the photographer. Use a tripod and a cable release and take a photo in good light. Make sure there is a very good line of definition that you are focusing on. Put the camera at the lowest normal shutter speed and try at a few different aperture settings. This little exercise usually highlights the problem as being the shooter. If you still have any misgivings try going though this link below or something similar. Don't worry about the reference to a specific camera.

The image of the vases is taken from a tripod (no cable release) and in manual focus ( both are manual focus). I don't know the settings (I'm at work now, don't have my camera). The image of the balls was handheld.

(btw, the image of the vases is growing on me).

OK, a couple more today from my favorite test subjects

To me, the first one below is in much better in focus, but a little over exposed

Concerns with my camera. If you look at the image of the vases from yesterday, just below the blue dot to the right is a red spot. (its right in the seam of the skirt of the coach) It was on every image I took yesterday. It is not on the images I took today.

Should I have any concerns?

(btw, the blue dot must have been a piece of dust floating by because there was nothing there and the blue image was not on any other image).

I can't see the dot......
re: focus- things can look nice and sharp on the small led screen but turn out to be too soft once you look at them large. keep playing and you will find the range of your lens and how to control the focus point. you can try playing with manual focus for a while to see if that helps you
