From the information I can tell this image is made in very poor light. Iso 800 and F8, 1/50 is not quite the settings that will make a good macro of a fly.
I do believe it's a very good attempt though, coz there is atleast some sharpness in the image.

ok.. first of all, when you shoot something very close up like this fly you need to use a small aperture (a small diafragm opening), so a higher f-number, for instance f16! that would give you more sharpness over all.
Secondly I would use the built in flash! then you can adapt your shutterspeed to both the flash and the f-number.
On my camera the shutterspeed won't go any faster than 1/250 when I use the flash.
If your subject is too bright, use a higher f-number! I think your lens can handle that.

I certainly hope this is of any use to you. Mostly it's a matter of playing with the settings a bit.
but if you want more sharpness, just turn up the F-number for a smaller diafragm opening and play with the shutter time.

:-) cheers!

Bonjour Jo

Nice try, you did very good with the reverse lens attached to another lens. Focus is quite good, composition great, exposure very good. I did something similar, check my image and go see the Workshop I included to see my camera setup. Probably similar to yours.

For Depth of field increase, there is only one solution, close down the aperture of the prime lens, not the reversed one. Mathematically, DOF is a function of the magnification ratio and the lens aperture. The more magnification you get the less DOF you get. The more you close down the lens the more DOF you get.

But be carefull closing down the lens, first you will loose a lot of precious light, and second if you go to far, a second problem called DIFFRACTION will appear. DIFFRACTION is an overall lost of sharpness (resolution) due to a very small size of the hole created by the diaphragm blades. As you close de lens down, DOF increase and also DIFFRACTION. There is no easy way in macro.

Great macro work here and the technique should be commended... macro is not my forte among other things but I really get interested with the photo specially if it is sharp like what you have here... many pinoys uses a reverse lens technique and I think it is very effective but I have not tried it yet. Keep it up.... and Regards
