Hi, I had an AF140C for a while a couple of years ago which I used with an A 100/2.8 macro I had.
In contrast (!) with the AF080C and presumably many other ringflashes, it has 2 semicircular flash tubes which you can switch on & off independently. This means you're not limited to full-on shadowless flash. It also has modelling lamps so you can preview the effect of the shadows. It's a very fine piece of equipment and gives a nice light - not as clinical as you might think. Ring flashes have many applications outside medical and nature macro photography. For instance, they are commonly used in portraiture and fashion by some excellent photographers. The AF140C is a good deal more expensive than the AF080C, but probably as good a ringflash as you'll get apart from the giant ones that fashion normally photogaphers use. --- Bob mailto:[EMAIL PROTECTED] Thursday, January 24, 2002, 10:03:46 PM, you wrote: > Hi Bolo... > I can't comment on these flashes specifically, but you can find out more > about their technical specs at Boz's K-mount pages: > <http://www.BDimitrov.de/kmp/flashes/TTL/index.html> > You can use step rings with the 080C to move between the 49mm mount on the > flash and whatever your lenses use. > As far as ring flashes go, though, be aware that the light from a ring flash > is a bit "clinical" (pun intended).
