ah ok, thanks. No wonder I was seeing lot of extra light when I trying to take a picture of a flower with table lamp pointed at it. Don't have extra lens rear cap, but will try to make a black paper hood for it.
But this takes lot of time. Spent about 3 hours learning how this whole thing works. Was also chasing an Ant, thru this, the small tiny ant looks big!! Couldn't get a good shot. Planning to sprinkle some food and wait for the ants to come, then try to take the pictures
stinger608 - with extension tube, the view gets very dark and you need lot of light on the subject (may be I haven't tried too much). But with reverse ring, especially if you have a lens with has manual aperture control the view is much brighter and subject is more magnified. I tried this with a 35-70 with macro capability lens which has F3.5 to 4.5 and has the capability to adjust aperture manually. So I kept the lens at 35 and F3.5. Planning to use the 18-55 but have to tape the aperture level at the bottom of the lens.
Now that I lost 3 hrs over the weekend and need to catch up with those lol.
