Originally posted by soccerjoe5 Cool! I haven't tried extension tubes, aside from the darkening effect I've read about, any other downsides on using extension tubes? I'm guessing you lose AF?
yes you lose about a stop of light, for me not a big deal... I generally use my AF540 flash with most of my macro stuff.
I tend to use the flash as fill rather than the main source of light. I have a Stofen on and angle the head so it isn't directly pointed at the subject in this case.
Gives a much softer and natural light.
My extension tubes are advertise as AF but its baloney... it doesn't work.
I got it for the A contacts so its simpler to use flash, however I often use manual flash in tricky situations.
Best thing of extension tubes is that it does not degrade IQ.
Another way is to get a Vivitar 2x macro TC and knock out the glass. Its is then a adjustable extension tube without having to mess with different tube lengths.
