Especially where I can take away the fear that I had, that the flash caused by his too narrow diameter at full frame shutdowns. If he does !!! I also have a Sony used him on the Alpha 850 50 / 2.8 macro, there is no vignetting at close range. For landscapes, where the ring flash would be absolutely out of place, it would cause an infinite focused already vignetting. TTL measurement works well, the flash output forth, may od to stop 11. 16 dimmed. Who does not live by macro photography but occasionally experimenting in this area, like me, will certainly find the Bilora D140 a useful cheap ring flash.
