Jan, you are throwing a wrench in my thought process and to be honest I really do appreciate it! You force me to think logically just as my daughter does at home ...I call her my mother because she is the more sensible one!

Yes, so far there has been no logic to my reasoning when it comes to photography gear. So let me try and type this out and hopefully come to a decision ...

You are right, the Tamron is good enough I guess and I do have the 50mm 1.8 II coming today (from what I've seen it is sharp but not the greatest background blur) but I really don't use a tripod too often.
I have the 70-200mm f4 IS mainly for the IS and the weight as opposed to the 2.8. The zoom range is great for running grandkids and dogs and the take-along weight is great for going to the park and I don't have to run around with them as much for a shot as I would have to with a prime. But the 200mm prime is great for low light when needed and blurring the background and again a nice weight for me (so the two sort of make up for not having the weighty 70-200mm 2.8).

So, hmmm ...looks like now the logical decision (and I am trying real hard to be logical on this one) would be to keep the Tamron, sell the 200mm and get the 135L.
