Originally posted by dms Assuming you were focused on the 13, the camera seems to be focused properly. At m=0.5 (which is about where you are at I believe) the depth of field is equal before and after the focus point--which is what you are seeing.
But the resolution (and contrast) is terrible! Hopefully it's just in the macro range--and indeed you should not expect a zoom to do well wide open at m=0.5. (I cannot say if this is what to expect from a consumer macro zoom at m=0.5--although since the f/8 is no better/actually maybe worse I rather doubt it will improve markedly if you stopped down to f/16-which ideally it should do.)
That was shot at about 6 ft distance using the standard, not macro mode on the lens.
The setting is one of the default settings in the camera modes,, vibrant perhaps, I didnt look.
Normally I shoot with the Muted setting with toning turned off, by default toning is turned on and set to red. I could re-shoot those again at macro, however many of my macro shots are sharper, It is the distant shots that suffer. A good example is Pine trees. At 500 ft the needles are all a mess and almost not distinguishable, this happens with the sigma, the pentax 28-80, and the pentax M 75-150. With all 3 lenses distant detail is lost. Shots done at 100ft are not so bad, but still not as focused as I would expect considering how well it does close up.
Not being savy I am not sure what m=0.5 means. Sorry for my ignorance on the technical side.
