I have bought and sold an M7 (not the same one) twice. Because it seemed to me that I didn't like the blinking numbers in the finder. But now that I've gotten comfortable with my M8.2, I'm used to the blinking red numbers. So. I bought another M7, my third. I hope I keep it this time.
I said I would never sell my Hasselblad Superwide-C. I sold it to buy the 40mm, so I could compose on the groundglass. I still have the 40mm, but I started missing the SWC. Flash back to the time I bought my XPAN, then later added the 30mm lens. I've become disappointed in the XPAN, and recently sold the 30mm lens kit, which has doubled in value since I bought it. I think the last straw was that I saw that the center ND filter sells used for around $550.00. Ouch, what if I ruined mine? And the 30mm took in more width than I wanted. I sold it for almost double what I paid, and began shopping for another SWC. And last week I received a very pretty SWC/M CF from KEH, with the proceeds of the 30mm sale. And had about $700 left over. This time I mean it: I will never part with my SWC/M CF!
The XPAN may go away.
Follow-up to my post in March: I did sell my Leica R outfit. Well, all but the 90 Elmarit, 135 Elmarit, and 180 APO-Telyt. Those three, I converted to Nikon mount. Roger will want to know why I made these changes. I did it so as to have both film and digital bodies I could use the same set of lenses with. Cuts down on how much gear I need to take along on trips. Now I can use my Nikon lenses, manual and AF, and my 3 Leica teles, on my FE2s; my FA; my D300; and D700. Oh yeah, and my F100 if I ever get around to using it.
And what did I do with all that cash from the sale of the Leica R outfit? That's where the M8.2 came from.
