I stupidly migrated from Pentax to Canon some years back....
....my L-series addiction started with a 7-200mm F2.8. My next fix was a 24-105mm
I went down-hill pretty quickly after that. 85mm F1.2, 14mm F2.8, 70-300 F4, 16-35mm...I was so hooked I even went to other dealers for a 8mm F3.5
...then I started on the hard stuff.. shooting up with a 500mm F4...I still wasn't satisfied. I need to get get more in.. so 8-15mm F4 was next.
And then there were the Tele-extenders. 1.4x, the 2x series III....but wait... I now have cravings for a 400mm F2.8... when will it end!???
