Alex,
Results from today. I tried the 28mm reversed onto tubes but magnification was no increase on what you are currently getting and the viewfinder is really quite dim making it hard to even find the subject never mind focus on it. I tried a different tack. Reverse the 28 onto a 2x converter. Now my converter is pretty rubbish ( recyled coke bottle job ![]() A quality 1.4 converter would no doubt produce better quality at a bit less magnification. For anyone trying this, ensure all glass surfaces are clean. Any crud will show up very sharply on the image. The downside of this degree of magnification is focusing. A focusing rail absolutely essential. I cheated and set this up on my milling table as I do not have a focusing rail but it proved the point. Flash was as per your set up diffused about 8 inches from subject to get an aperture of f16. Then reduced to 1/2 power for the shot without converter. The attatched images are all full frame. The first two are 2x converter with reversed 28 and the last just a reversed 28 for comparison. The subject is the dreaded green fly. Adults are around 2.8 to 3mm long. The warmth of the workshop seemed to have them multiplying at an alarming rate. ![]() Don |

Wow Don they are fantastic you have managed a good DOP considering its only f16. I haven't been able to find anything yet to make the attachment for reversing the lens. I would love to have a go.

![]() A 50mm reversed on a quality converter is also an option for less magnification. Your gallery shot of these beasties was in my mind while I did these. Probably inspired the subject. Don |

Have fun Alex and remember to post results. I am sure you will.
![]() A 1.4 converter should, although giving less magnification give greater DOF. In this case anything better than recyled coke bottle should give good results. You will be pleased that working distance does not change by much. I did manage to tape the 28mm hood over the lens mount, so rear element was not too affected by the blast of light. Don |

Hi Don: Well I had a short go at it this evening. I got a couple of focused shots and you are absolutely right about the tubes.... Too dark for focus. At least for these eyes... I think in brighter light this is going to be a sweet set up to play with .... I am getting an error code and shut down trying to use my Tc.... I'll have to investigate it....Err 001. The other immediate impression I have is that the DOF is so shallow unless turned down to f16 (for me anyway) which seems to be the sweet spot... Couldn't see through the lens for focus except under a bright light.... You are absolutely right about the need for a focusing rail.... This is a handful to hand hold steady
