rkyobo 0 Posted January 11, 2007 Great macro of these ants, Leszek! Good detail, and very nice composition! Great work! Check out my photo of ants helping each other out. http://www.photo.net/photodb/photo?photo_id=4879886 Link to comment
les 11 Posted January 11, 2007 Thanks. This is rather an accidental shot - I can't get a coupler ring, so today I bough 2 cheap UV filters, removed the glass and glued the rings together. So, now I can put 50/1.4 on 100/2.8 macro. This gives me magnification of about 2.3 (measured), and above is my first shot using a reversed 50 on top of 100 macro. Still waiting for Kenko tubes in order to employ 1.4xTC and a second flash :D Link to comment
peter_houtmeyers 0 Posted January 12, 2007 I can see you are experimenting with equipment to get magnification. Your technique of glueing two UV -filters toghether is a good idea untill the glue lets go. Result one broken or scratched 50mm1.4. I you use two 58mm cokin filterholder-adapters its much less expensive and without the risk of damaging your lenses.These adapter have the male thread at one side and the other side is a big flat surface(flange). In this surface you could drill some small holes(4).The flanges can be bolted with small bolts. If you drill the holes in the same place every time, you could make several combinations with other threadsizes. The A system from cokin is the cheapest and has many different thread adapters.I also searched for the reverse-rings but without succes. Link to comment
les 11 Posted January 12, 2007 Thanks for the comment, Peter - in general I would say you are right, but: -inside the filter frames there is 6mm wide plastic ring cut from PVC pipe -on the outer surface, the ring has a layer of fiberglass glued with epoxy -both filter frames are screwed onto the fiberglass, with epoxy filling the female thread. (As you can see from this - yes, I am an engineer :D) Link to comment
