I've started with my first DSLR, the Canon 5D Mark II and a 50mm f/1.8 lens 2 years ago. This is my collection of gear so far.
Body: 2x Canon 5D Mark IICanon 16-35mm f/2.8L II: (The least sharpest of the lens I own. Haven't used it much. Plan on using it more for video with merlin steadicam)
Canon 24-70mm f/2.8L II: (Just received and lovin' it! Can't wait to go out and shoot with it!)
Canon 70-200mm f/2.8L IS II: (Big and Heavy, but outstanting lens. Haven't been using it much since getting the 85mm 1.2)
Canon 24mm f/1.4L II: (Just ordered this lens. Will receive it next week

)
Canon 35mm f/1.4L: (Love the focal length and colors. This is my most used lens.)
Canon 50mm f/1.2L: (Not exactly the sharpest lens wide open, but has a magical, 3D look to images when shot wide open. Got some great shots with it)
Canon 85mm f/1.2L II: (Just an amazing portrait lens. Sharp as a tack wide open. Just love the seperation and creamy bokeh it produces.)
Canon 100mm f/2.8L Macro IS: (I'm not really a macro shooter. Just have this in case I need to take detail shots. Lens is super sharp!)
