Dental macro for sony body: ring flash

Used with sony body and 100mm Minolta f2.8 macro for top notch dental images.Not an easy setup but great results using aperture priority. Switch the flash on before the body otherwise the a300 won't realise it's attached and will use the inbuilt flash!

Consistent Output; Durable; Powerful Output

Good product at a much better price than Canon's own variant
