Good start.
I suspect the 135mm lens you used is not up to doing macro work. There is a lot of colour fringing, purple around the fly's front legs and green around its back legs in #2.
The images also are not sharp, maybe because the SR system had not stabilised. You pressed the shutter release before the SR indication appeared in the viewfinder (according to the EXIF data).
Keep at it, you'll get there in the end, but if you really get the macro bug, you'll want a dedicated macro lens.

Very new at this but it is a start
Hi David, would look better with a little more depth of field DoF if you have enough light, try stopping the lens down to f/8 or f/11. You may need a flash or failing that a tripod to counter the slow shutter speed you'll have. The purple fringing may actually be a result of a wide aperture at close range say f/2.8 giving Longitudinal Chromatic Aberrations (LoCA)LoCAs (non-coinciding focal planes of the various colors) are a further aspect. LoCAs show up as magenta colored halos in front the focus point and green beyond at large apertures.[IMG]http://i291.photobucket.com/albums/ll298/badpianoplayer/First%20year/fly.jpg[/IMG]

A simple explanation of DoF can be found here:

Hope this is of some help.

That's a big improvement indeed! The next step is to try and get the point of focus on the eyes - it's tricky as the depth-of-field is so tiny but it makes a big difference.

Hi David
Glad to be of help, just a small point, if you're using flash you could try using a diffuser on the head to soften the light a little, failing that bounce the flash off a nearby reflective surface instead of directly on the subject. It may also help to use the lens in manual focus to get focus on the eyes if you wish.
Best regards,
John
