Well regarding the thread of calypsob "extension tube problem" instead of hijacking his thread I open a new one..because my problem is not that bad and I think is not because the shape of the elements of the lens I'm using..

I'm using 2 sets of extension tubes on a 135mm lens

Well its giving me around .98 magnification, with a working distance of 28-30cm !! So I really want this to work..

When it doesnt glare, can get this..

Which in IMO are very sharp for a cheap combo..

If I put my DCR-250 on top I get around 3:1 mag with a working distance around 9-10cm

But when the flare appears is like this.

BTW: Right now I can't afford a real macro lens, so what do you think I need to add/do to my tubes to eliminate that glare..


Thanks.
