Good morning, e been us;
It has been a while, hasn't it. No response yet. OK. Let me add to the confusion:
Finding some of the more rare, or at least less popular accessories, for a camera can be a challenge. My own chosen or preferred brand is Minolta, where the new purchasers and owners of the marque ordered that all of the parts, literature, accessories, and everything else associated with the manual focusing forms of that brand of camera, were to be thrown out and destroyed. What a shame.
I have purchased a camera or a camera kit, just to get one of the accessory items in it or with it.
For getting a non-common focusing screen for the Minolta X-700, I bought another camera (Forgive me, Father, for I have sinned.) which had that particular focusing screen in it, just to get the screen. Clearly I did not need yet another X-700 body, but that was the only sample of that screen I have ever seen, and it was attached to that body. Just to compound the problem, yes, I did send the X-700 body out for a full CLA also, and that added significantly to the overall cost of the purchase of that focusing screen. I do have many samples of the regular X-700 focusing screen here already (no, please do not ask) so having the normal screen put into that body was easy during the CLA; they "did it for free." And, now the body I wanted to have that special focusing screen is now equipped with it.
Yes, some of us are much more susceptible to GAS than most others. Fortunately for me, the Canon marque is not one for which I have a strong urge, so it has been possible to resist up to this point. However, I do admit that there are a couple of Canon EOS original Elan bodies here (all I wanted was a film body that my other EOS lenses for the DSLR could go onto), and there is the Canon Pellix QL that just "arrived" one day (another repair and CLA), and there are the Canon EOS-20D bodies and the venerable EOS-D60 body and the lenses for them. There might be an EOS-50D body some day. And at some point, there is still a Canon F1 and some lenses to be purchased to replace what a kid "lost" a few years back.
I really do need to find a chapter of Cameras Anonymous.
