Hi!

I have finally taken the plunge encourage by the amazing results obtained by so many forum members. However i was disappointed to see that the vignetting is prohibitive even at the telephoto end. My equipment is G3-58mmlensmate adapter-uv filter-reverse 50mmcanon lens f2.0.

Is the vignetting expected? Does everyone using this technique get vignetting. Is it normal to expect this and then having to crop the photographs later or am I using a wrong reverse lens or doing something else wrong.

Cheers! and hoping to resolve this problem with your suggestions.

I posted a similar message a few days ago, but with a Canon FD 50mm f1.4 SSC. I got no response from those touting success with this method. So count me with you and the ever-present vignetting. I gave up.

cheers,

I thought the vignetting was expected with this method - see link

Hi. thanx

does this mean that all the others with spectacular pictures have cropped their pics. It will be helpful to hear from others who have posted pics taken with reverse SLR.

You have to fully open the iris on the reversed 50mm lens manually. The Nikkor 1.4 I use has a lock to hold it open. Otherwise you have to find a way to block it open.

I think this is what you are taking as vignetting.

You did get replies, guess you never saw them. Last two in this thread:

Did you try manually locking open your aperture?

Looking at the photos at the link poppy supplied, I can see one possible reason why I am getting vignetting (and the aperture is set wide open f1.4) My lens is substantially longer physically than the 50 f1.8 (I'd guess 2x) The FD 50 f1.4 SSC is a very old lens, and was at one time considered a reference lens, but it has been left behind by L glass and modern manufacturing I'd guess.
So, as someone said in a very early post on this topic, your success depends on the lens you have to reverse. And one variable would seem to be vignetting.

Hi all

Please find a lot of new info re macro and close-up with the G3 at http://homepage.hispeed.ch/flowe/digifoto/g3-close-up.htm - repeatedly updated.

The SRL reference in the present subject line is irrelevant: my personal favorite is a very old projector lens. "Retro lens" is more to the point.

Vigentting is *not at all* unavoidable - it depends on the lens you use - see link. There you find too a brand new section on the use of the Olympus TCon17 at close quarters.

For master pieces in G3 macro photography go to Marc Plonsky at http://www.mplonsky.com/photo/article.htm

Enjoy
