<p>I have a Sony a100 digital camera and three Minolta film cameras. (Maxxum3000i, Maxum50. Maxxum7000)<br>
I also have about a dozen lenses (some Sony, some Minolta) that I use on these cameras and all of them easily mount/unmout on any of the cameras. I have no problems with these lenses or bodies.<br>
I bought a Telesar Zoom Slide Reverser. It is simply a macro lens with a way to insert a 35mm slide in one end and has "T" mount threads on the camera end.<br>
I found a T-Mount adapter on the web that says it fits both Minolta and Sony a100. When it arrived, I tried to mount it on the Sony Alpha and a couple of the Minoltas. It was slightly to big a diameter. I could not insert it into either camera. I ordered a second one from eBay and it will insert into the bodies of all four cameras, but it does not lock when I twist it to the right. It is also to loose, and seems like it is to small, it slides when pushed side to side or up and down. If I mount the lense, the weight of the lens causes it to come off the camera. (I broke the Telesar when it hit the floor.) So I found a Kale slide duplicator and bought a third adapter. This one is just like the second one, other than the first was anodized black, this one is silver colored. Again, it does not lock when turned to the right, shifts, and easily falls off. It also seems to small. I compared it to the Sony Alpha 100 body cap and it is definitely a smaller diameter, It almost fits inside the part of the cap that goes into the camera rather than matching up with it.</p>
<p>Am I crazy? Should I be able to screw the adapter to the slide copier lens and then just easily swap it from camera to camera like any other lens? Should it just line up the red dot and rotate about a quarter turn and click and lock? Those last two just keep rotating and come back off.</p>
<p>BTW, I don't want to use this setup to convert slides to digital. I do that already with a 22 megapixel scanner. I just want to make 6 copes of a set of 800 slides.</p>
