Of course I'm using "love" in a non-literal way, but there are some parts of my bag full of gear that I just feel click for me.
The 40D. This is to me one of the best purchases I have made. Even though it has the same resolution as the 1000D, there's just something about he 40D that says CAMERA. When you hold it, it feels substantial, like there's something more than simply wiring and electronics. With the 50D, 60D and (the surely upcoming) 70D, it has been superseded many times, but there is still something to it. It keeps clicking and it's all I need. (For now, at least...)
The 85mm f/1.8. This is one of the biggest reasons to get into the EOS system, in my opinion. While probably over-shadowed in use by the 50mm f/1.8, I would reach for the 85mm any day of the week, despite the extra cash I would shell out. The USM, the large aperture, the size, the build quality, the image quality, it's all spot on. Put anything in front of it and open up the aperture and that's pretty much it.
And the latest addition to the list, the Manfrotto Nano 5001B. I can honestly say that this has been almost as big of a revelation as the first time I shot a flash off-camera. Now I can get a light-stand with me without the bulk and with very little extra weight. Fold in the legs and I have flash-on-a-stick that I can hand-hold.
The list may grow if I ever start shooting with more expensive equipment, but for now, it's a good start.
