I had my E-5 out for the first time in three months or so, doing some testing with the Micro-Nikkor 55mm f/3.5 that I purchased recently (for use with the GXR and A12 Camera Mount, when it arrives) and comparing it to the Olympus ZD 50mm f/2 Macro. What a brilliant old lens the Nikkor is, and what marvelous camera the E-5 is! I don't really need it any more, my photographic goals and shooting needs have changed so radically this year such that the work I outfitted myself with the E-5 kit to handle doesn't exist.
So do I sell it off or keep it for that very infrequent use? It's lovely equipment ... the body is superbly responsive, produces outstanding image quality, the lenses are equally superb ... but it seems silly to have what amounts to $5000 or more worth of excellent camera gear sitting in the closet unused.
It's the Photography which endures, not the equipment.
