The 7D is a fantastic camera and still very relevant in the Canon lineup. The 7d is a great match up with any of the EF lenses, especially L glass. The 24-70mm is fantastic on the 7D, it's only not wide enough if all you shoot is wide... If so, it's still a great walk around lens. The 17-55mm lens is fantastic on the 7D and the mid range and long lenses are incredible... +1
I had the 1DIIN and the 24-105. Bought the 7D and the 15-85. Sold the 1DIIN and the 24-105. Bought the 17-55. Sold the 15-85. If I had only one lens, it would be the 15-85. Since I have the 100mm macro and 77mm filters, I kept the 17-55. I does miss the 15mm end though.
I've used numerous Canon bodies, and agree the 7D still has a great place in the Canon line-up. I expect I will keep my 7D till it dies ... It's handling is SO much better than any other Canon APS-C - and while it lacks some of the FF advantages in terms of IQ, often that's only noticed in pixel peeping.
I have several Canon lenses, including L glass, and my 7D is most often paired with the Canon 15-85mm, then Canon 70-300mm L (ie at 480mm in 35mm equivalent). I also find my 7D great for macro work (with the 100mm) and it handles landscapes / ultrawides well too, eg 10mm (16mm equivalent in 35mm format) sharp corner to corner.
When / if the 7DmkII comes out, I am keen to see what it delivers. All in all, I'm sure Canon will give us good tools to continue shooting photos.
