From the look of the MTF, it's much better at the 300mm than the outgoing model... (and all current versions)

The 70-200 f/4L is slighly sharper, especially in the corner - but who is counting (i.e. very close)

Of course CA (which the old one is infamous at) is not depicted in an MTF so we'll have to wait for the real lens. IMO they're revamping their entire line especially with the full frames coming...

There are other things to consider besides just the optics- it won't take much improvement to be a vast improvement over the old model.

The new lens still uses the MICRO USM instead of the much, much better RING USM, so AF speed on the 70-200 f4L will still run rings around the new 75-300 and the 70-200 f4L does not extend when zoomed. The new 75-300 has the same old, tired look of the prior model, meaning it will still probably extend when zoomed. Ergonomically and optically the 70-200 f4L is still a much better lens. Used with the 1.4 converter I wouldn't be suprised if the 70-200 f4L is still better than the 75-300 at (close to)300mm.

One last thing- the new lens, if it really does come out at $650, is almost $100 MORE EXPENSIVE than the 70-200 f4L, which is utterly rediculous when you compare the two optically at comparable focal lengths, and the extra stretch to 300mm is NOT worth the difference comparing these two, even with the newer version of Image Stabilization.All the newimage stabilizationmeans is you'll be able to see how lacking optically this new lens is at even slower shutterspeeds.

If you insist on buying a QUALITY300mm zoom, there's an even bigger arguement now to buy the 100-300 f4 Sigma with Canon jacking the price up on this model.

I believe the previous model had the first generation IS and now this one is much better.

IS is ruining everything! Price-wise, anyway....

But either than that, I'd also probably choose the 70-200 f/4 over this one. Or even the sigma 70-300 apo...

because it appears to be the exact same design with a new low dispersion piece of glass and a new IS system.. the front will still rotate during focusing, this will make circ-polarizers a real pain..

if it will be priced similarly to the 70-200 f4L, there is no doubt in my mind which is the better bargain ( read L )..
