So, I just caught myself recent doing something I've been denying for a year or so (after I relized I was doing it).
$1500 for a new bike I want? Nah, too expensive to jusitify to myself.
$1800 spent on my (first ever needed repair) car. Damn that was a lot!
...and so on...
But $1400 for a new lens... not that much compared to what some of the lenses cost. [^o)]
How many of you find that when you take something that you think is "too much" and a lens that costs roughly the same amount... you find yourself justifying the lens purchase much easier?
It's a sickness we have.
