I'm glad that you have finally settled on your lens lineup.
BTW, nice bird pics, too.
Hin, I like your idea about having some buddies on the forum to be accountable to when contemplating lens purchases. The little group could simply be called "LBAs Anonymous". For those who are contemplating stupid lens purchases, they might be reading comments such as:
"You need that lens like you need a hole in your head."
"Step away from the computer and nobody will get hurt."
"Step away from your wallet and nobody will get hurt."
"If you have to take out a loan to have that lens, then it's not worth it."
"You already have 4-50mms; do you really need a 5th one?"
"If you buy this lens, are you going to be able to eat for the rest of the month?"
"If you buy this lens, will your wife stick around?
Anyhow, you get my drift.
