Hi Gerry,

If you rotate it to the minumum focusing distance the helix will allow, the back element will go inside the lens, making from the mount a good hood. Just be sure to protect the gold-plated contacts (I did a hole on a cover for this purpose). As you already noticed, the working distance is very narrow, so any other kinds of "hood" will actually block the light falling on your subject. I haven't seen any flare, even when flashing just next to the setup. As a side note: apart from trashing film, you can also dump a lens... Yesterday I tried to photograph the incandescent filament of a 1000W lamp... Well, stupid thing to do... The back of my 50f/1.8 started to burm immediately after I turned the damn thing on... Due to the short working distance, the back of the lens was touching the glass of the halogen... I guess I know now why I haven't seen such a picture ;-) ;-) Believe it or not (I couldn't) the 50f/1.8 is still working, but now it looks like the Monster of the Wax Museum. > A focusing rail would also be nice to have, but I think I'll see what > results I'm getting before I order one of those. > You have some focusing abilities by zooming in and out and micro-adjustments using the focus of the 75-300. Trying to frame your subject will prove harder than getting it in focus. (But that second part is not easy neither) Please let us know how it goes... I'll try to scan some pics to let you see some of my trials.
