Nikon D7100 with my Sigma 150mm Macro lens....
That shot shows the actual size of the spider compared to the size of my camera sensor....the spider's body was about 8mm long...
The macro setting on your P&S/bridge camera is most likely not true macro, more like "close-up"...try moving away from your subject a bit and see what happens...
If you have a view finder (or you can use the LCD screen) just set manual focus and move back and forth until your subject is in focus...this is how I shoot true 1:1 macro on my camera...
