I thank you very much for your impute I have about two weeks to really make that decision, and with the additional info you gave me, I'm going to look for prices now. I say two weeks as I have a mandatory withdrawal from my annuity I had to take and am just waiting for the cash. My wife got her pup, and I'm getting my lens. I got the better end of the deal.
I will change the 100mm USM to a 100mm F2.8L IS, that is a given, and I will probably stay with the EF 70-300mm f/4-5.6 IS USM, it's now about finding the best deals.
Again,
Thank you
