2.8:1 Macro Set-up

This is the set-up I am currently using to achieve my 2.8:1, at the sensor, macro images. I am able to get this magnification by stacking teleconverters between the macro lens with its 1:1 tube and the camera. The items in this set-up include, from left to right: 1. Tamron Adaptall-2 Model 52BB 90mm f2.5 Macro Lens, shown fully extended for closest focus and highest magnification. 2. Tamron Adaptall-2 18f 1:1 Tube. 3. Tamron Adaptall-2 140f 1.4X Flat Field Teleconverter. 4. Tamron Adaptall-2 01f 2X Flat Field Teleconverter. 5. Tamron Adaptall-2 Pentax K A Mount. 6. Pentax K20D Camera with attached neck strap and electronic flash extended.


For this image, I used my Canon Digital Rebel XT (350D) Camera and AF Canon EF-S 18-55mm f3.5-5.6 (Kit) Lens, hand held, manually focused, Focal Length 38mm, ISO 400, f18, 1/200 sec, with fill-in lighting from camera's built-in electronic flash. This is a full resolution Large JPEG and is Straight Out Of Camera without any post-production, editing, adjustment, cropping, or re-sizing.
