I will have one as soon as I can get my hands on one, and if it focuses as good or better than the 1D IV will have 2 :)

Its exactly what I have been looking for and I know my shutter count on my 1D IV's is really getting up there so its time.

What do you mean this weekend? I read that this camera does not ship until March.

They will be showing it at some events, although I haven't followed any where/when info.

So, apparantly us "mere mortals" are not yet allowed to take photos with the 1DX yet, but Canon does have its team of "superstars" checking it out. I suspect that under their contract they are not allowed to post photos though.

But Vincent Laforet has posted a couple shots of the rear LCD showing shots taken at ISO 52,000:

Granted, you can't tell much from the 3" LCD, but at least at that high ISO they are not garbled with noise!

Jay, hmm...I don't have a twitter account. The first time the guys in that thread posted links I got that same result -- but for these the shots actually come up!

Well, check out these two posts in the 2AM thread before they get zapped for unauthorized posting of someone else's image:

I don't do Twitter either, but the pics came up okay. That first one is amazing...at 10x on 51k ISO, that is pretty damned cool.

I look forward to seeing what the pics from ISO 100 will look like blown up to A1 size....600x900mm.


Growing old disgracefully!

I'd be more impressed if the shot showing the LCD had been taken at 5,200 ISO...

You mean 52,000 not 5,200 ;) And they look okay...definitely noticeably noise, but not too bad... (also, no Twitter for me either, but the link works)

No, I meant what I typed because I was quoting the number Tony posted. Maybe he meant 52,000...

Huh? Why?

A photo of a photo on another camera's LCD is somewhere slightly beyond useless.

Show That the determinant of the group of 2 by 2 matrices is a group homomorphism to R*, where R* is a multiplicative group of nonzero real numbers

Still too easy. Your question is merely a fancy way of asking us to prove that det(A*B) = det(A)det(B) for 2x2 non singular matrices A and B. Which is trivial:

Let A = [a b, c, d], B = [e f, g h]
So AB = [ae + bg af+bh, ce + dg, cf + dh]

Now det(AB) = aedh+bgcf - afdg - bhce
also det(A) = ad-bc and det(B) = eh-fg

So det(A)det(B) = (ad-bc)(eh-fg) = aedh+bgcf - afdg - bhce = det(AB)

Of course, I assumed you meant the multiplicative group for the 2x2 non-singular matrices, since that is where such a homomorphism exists.

:-P

If you notice, I was quoting Tony (albeit, his wrong post, but the right guy ;) ).
