1d IV vs. 7D II

;)

Well, while it appears the Dodo was fairly swift. Using a modern proxy, the ostrich (as a large, land bird) runs about 40 mph, I'd put an uneducated, non-scientific guess at about 25-35 mph peak speed.

Assuming that the origination of the Unicorn is from people seeing Rhino's, the White Rhino can run about 31 mph at peak.

If, instead, the Unicorn is really someone's great practical joke and it was simply a horse dressed up, a Quarter horse can run about 47.5 mph.

So, if a Dodo and a Unicorn made a bet as to who would get the land-speed record, if it's a Unicorn based on a White Rhino, it might be a toss-up. If it's a Unicorn based on a dressed up horse, pretty much the horse would win.

And now I feel all proud and geeky and self satisfied that I have go through the time and effort to attempt to make an absolutely meaningless point about something completely unrelated to the original topic.

That's all fine and dandy... but neither will approach the airspeed is of a swallow carrying a coconut

I think Arthur et al. (1975) show that at least two swallows will be required.

What do you mean by overall land speed?
No offense to Drizzzt's excellent deductions, but if we are talking about also running over terrain that horses (uh- unicorns) cannot tread easily, like swamps, that will severely alter results.
By the way, thanks to Drizzzt for clearing up the issue about the dodo's speed. I had maligned the dead guy in an earlier post ("1/125 isn't enough to shoot a dodo with the 135L, let alone a hummingbird").

On topic: having used neither 1DIV nor 7DII, I can only surmise that the 7DII will have better IQ due to it's more advanced sensor and processing capabilities. Canon has discontinued its APS-H line, and the 70D is a already a better APS-C than 7D in so many ways for the value segment. So I think Canon will go all the way for the niche segment of a high-end user who need the extra reach of a crop.

I'm certainly hoping the 7DII will be a viable replacement for my high-milage 1D MkIV based on all sorts of performance parameters. But until the over-anticipated 7DII actually ships, speculation is next to useless.

Reading this thread, I can't understand why I never see "sticky" threads on this forum.

BTW, I'm sure there are been people who sometimes complain about their 1D IV, but nobody has ever complained about his/her 7DII, so we can induce that the latter is better from a KarlPopperian point of view.

Okay, I know one is discontinued and the other is non-existent, but this is mostly for fun and a bit of learning.

Apparently, you have not used the 1DV.
