A question about "Macro Coupler"

I just seen in BHphotovideo, they have an equipment name "Macro Coupler". I know that used for attack lenses face to face. Do you have any picture when you taken with equipment? When you take with equipment, which type of focus you use is the best (Auto or manual)?

Have a look at video No. 4 in the following link. It may answer your questions :

Below is one of the first I tried with this technique using a Sigma 18-50mm lens and an old Canon 50mm FD coupled together. Manual focus works best. This was before I had the 100mm f/2.8 macro lens, and since I got that one I haven't tried the reverse macro setup again.

Here's a couple more I dug from the archives:

Thanks for this post. The video library is awesome and I learned some great stuff after viewing only 3 videos.

I especially like the tripod mounted computer stand for tethered to a computer shooting. I like to view my portrait images on a computer screen and having a stand for my notebook like that is described will be great! I am glad that I didn't get rid of my old 3001P tripod and ball head. Tomorrow, it becomes a computer stand!

Thanks all!

Steve... Thanks for post , bookmarked , will go back later .
