Best camera advice (maybe life??). Do not wait. When you are ready, do it. For cameras, when you are ready and have the need, look at what is available and make the best decision you can at that time. There will always be a "new release."
For what it's worth, the rumblings and patents on new lenses can still mean that the new lenses are years away. We have all seen multiple patents for different lenses well before their actual release.
So, you wait based on a rumor, you could easily miss many great photography opportunities.
Thanks for the reply. I know what you mean, and I agree, but on an item of this dollar value, it's a little different. One has pause when the current version is 6-7 years old, and there are rumors of new DO versions. I did own the previous (IS) version of the 500 f/4 for two years, and the weight was an issue. I've been using the 100-400 II for the last ~year, and while it is good and very versatile, the 500 f/4 II keeps me awake at night - LOL. You'd have to admit that the DO version of the 500/600
could indeed be released soon, maybe even announced this Fall, and the feeling (at that time) of having just bought the "old" II version at full price, should that happen, would not be good, especially when size & weight are a huge factor.
