Need help for TCON-17

[jojojoy]

I am using D7hi and just received my new TCON-17 lens yesterday.
Just wondering if anyone have focus problem with TCon-17 on?

I can never get focus in normal setting.
In Micro, it seems a little bit better.
However, the pic. are still not acceptable.

Can anyone help?

I did circle on the photos.

Also the radial blury ......

I don't know if it is the len problem.

I don't have a D7hi; but, I do have a A1. I have never encountered any focusing problem with the A1+TCON-17 combo. The quality of A1+TCON-17 may not be as good as other combinations and also shows some slight vignetting, it is not that bad especially the chromatic aberration (i.e., purple and greenish fringing). How did you mount th TCON-17 on your D7hi?

The following two threads discussed some converters for the A1. I believe they should also work with your D7hi: http://www.stevesforums.com/phpBB2/v...ic.php?t=17608

I have a auto-focussing problem with the TCON17 on my C750 for distances closer than about 20 feet. I have to use manual focus.
