The one waiting the new version of 100-400 IS, investegation

[tome223]

I have the current version of the 100-400 and love it.  Am planning to get a 17-40 L and it's nice that the 17-40L, 100-400, (and 24-105 L for that matter) all take 77mm filters.  Something to consider, who knows when the newer version of the 100-400 is coming out - and if it does - what it's filter size will be.  I for one like the push / pull of the 100-400.  Even if a new version of the 100-400 would come out I think I'd invest my money in glass elsewhere rather than in the most recent model.

I am waiting for the new version.

I might have the funds from a tax refund around may/june of next year, if by then it's available, then for (almost*) sure I'll get one, if not, I'll have a tougher time deciding between the existing 100-400 which I have actually used and I'm in love with, and the 70-300 L which I have not used but I would believe might be an excellent choice given the advancement in technology when compared to the 100-400, but I certainly don't have any hardcore data to support such statement.

*almost in reference to a potentially obscene increment in price, like going from $1600 US to $3,000 US. In such case I would think, darn you Canon!
