Well, I've gone and done it, I was after a 55-230 II but bought the 100-400!
It had come up before and I missed it - mostly on purpose as its so expensive, then it came back at a good price, so I thought - nope... not unless the XT1 sells...
Guess what within minutes the flipping thing sells (for a bit less than I wanted)... so I try to talk myself out of it again, this time looking to my wife for sense...
No that didn't work either, she says go for it, but as a final barrier I know that the price is firm but as I'd not got what I wanted on the XT1 I still put in an offer, hopefully that'll stop me buying it when he refuses - a final get out...
lol, no he comes back with another price... damn... guess I just had no choice
This was bound to happen though, or something similar - my camera bag was getting much too light with only mostly shed loads of accessories - GAS was seeping under the door with someone on the other side with a pretty heavy set of bellows!
On the up side I know how these things work with me, buy the 55-230 because its cheap and light, but mutter about the range, then at some point buy a 50-200 because its a bit wider and in time get the 100-400 anyway, so at least I should have saved a few quid in trade-ups!
