Lenses / Re: A New EF 800 f/5.6L IS II? [CR2]
« on: October 24, 2012, 06:35:26 PM »

800mm f/4.0 would have a slightly smaller front element as the 1200mm f/5.6 but the physical length would be a good 6 inch shoter. Would weigh about 16.5kg.



Now the succeeding article is now CR1. Hmmmm...

The lens looks heavier than the girl behind it  ;D

Wait, canon is pulling the wool over everyone's eyes. When they start producing the large megapixel ff dslr, pros will start selling 5d mark iiis cheap. Then the price will go down encouraging those who buy the 6d to move up to the 5d ii, and rebel users to get the 6d, and there will be a major price drop on the rebels, X0d's, 6d's, 7d's, and 5d mark iii. Worst case scenario, you wait and the price doesn't drop and you find a used one.
Sure, and when they start producing the Gigapixel SLR the 5DMkIII will be sold for 10$  ;D  ;D  ;D
Seriously now, this is just an exaggeration to point out that we can always wait for something better and miss while we wait...

EOS Bodies / Re: What's a good camera?
« on: October 24, 2012, 11:21:40 AM »
I'd like to see a black and white camera.  Not monochrome, pure binary black and white.  Each pixel either on or off, nothing in between.  DxO Landscape Score = 1 and no argument about it.

I love images like this one:

 

 :P

Hmm wouldn't that have practically zero noise (as long as the "sensor" would be able to distinguish between black or white) ? In that case I imagine a DXO ISO noise score of say ... 100000  ;D  ;D  ;D
Now how this contributes to the final score ?  ;D

Making the best of the six month delay I figure I will put $10 or $20 in a jar each week and then when the upgrade comes out I'll get a 2.0 X III extender for my 500 and it will be almost "free."

Then compare the 5D3 with 500 + 2.0 X (1000 mm) vs my 7D with the 500 + 1.4 X (1120 mm) and see which one wins.
Well this is interesting! I do have a 2X but I miss a ... 500mm!
How many days must I do the same ?  :(  :(  :( (Yes, I can divide please don't answer!)

Aha! We have all fallen for the oldest engineering trick in the book - tell 'em it'll take 6 months when you know it'll take just 2 or 3 so when you release the fix "early" it looks like you're a miracle worker who puts the customer first!

Plus all this at no extra charge! Seriously? Canon had to say that? If I ever have to pay for a firmware update that's when I jump to Nikon. Whilst I like my 5D3 it was initially over-priced as shown by the big price-drops now available. Still, at least I've taken enough shots that I couldn't have got from the 40D I had.  ::)

I predict January for the release.....or August...or....
For a six month delay they will have to squeeze in the AF illumination fix, improve the minimum shutter at auto iso and whatever else has been mentioned as a shortcoming that can be solved by firmware. Even so they will be late!

1251
Unless ... they plan to release the AF illumination fix as a minor upgrade much sooner   ::) (Now we have to laugh from time to time)

1252
Red Light AF illumination in AF Servo would be much much cheaper though  :( ... for us  :D

Can anyone explain the particulars here what this means with regard to video with the 5D3.....?
It's only relevant for professionals. There are no consumer grade hdmi recorders because it would mean digital video copying on a humungous scale. The cheapest recorders you can find are in the $5K region, I think.

Uncompressed does mean that you can achieve a higher bit rate than what is stored to the cards, but I couldn't say anything about the magnitude of the difference.

For me, this is a forgettable extra, anyway. Ymmv :)


I think this will do it. It isn't $5K but it isn't cheap.

What I find puzzling is the 6-month delay. It's almost as if this really is a reaction to the most recent Magic Lantern announcements.

Not recommended as a solution for recording the live HDMI output of DSLR cameras.


How about this one: http://www.bhphotovideo.com/c/product/858661-REG/ATOMOS_ATOMNJA002_Ninja_2.html

Yes! It looks OK and ... 1000$ :(

Canon General / Re: To take on a partner or not?
« on: October 23, 2012, 10:25:03 AM »
Well that depends (suprise!) on how good friend of yours he/she is...

You must be 100% sure of your partner's character (OK pretty close to 100% is more realistic). On the other hand it is a part-time job so it seems you have nothing to lose to try (except your friend in the worst - and possibly unlikely-  case scenario).

Glad I ... could NOT help but I am afraid this is a decision you have to make on your own...

1258
And what about the minimum shutter in auto ISO? Doesn't need an update (to add at least 1/500, 1/1000) ?

1259
April 2013? You mean April 1st 2013? Because in that case everything is explained  :P

True...but what if it was lighter than the 600 II?  600/4 = 150mm front element, 800/5.6 = 143mm front element...so lighter is possible.

Also, I think they need to update the 800/5.6 for optical performance.  Those who do their research (which I would hope is almost anyone spending $13K on a lens) pretty easliy learn that the bare 600 II is optically better than the 800/5.6, enough better that you can add a TC and it's still better.  The 600 II + 1.4xIII is better than the bare 800/5.6, plus it's 40mm longer, lighter and cheaper, and offers f/4 when you use it without the TC.  The 600 II + 2xIII is optically better than the 800/5.6 + 1.4xIII, too, and likewise it's longer, lighter, and cheaper.  So, with the 600 II performance, I see no real need for the continued existence of the current 800/5.6.

How about the current 800mm vs the 400/2.8 + 2xTC?

Any new 800mm would have to beat both the 400x2 and 600x1.4 combos
...
unless
...
maybe we could be in for an 800mm f/5.0, or even an 800mm f/4.5 or f/4.0? I know canon has some serious superstition about non-whole-stop lenses (except in 50/85mm and vari-aperture zooms), but they could use even a 1/3rd-stop advantage as marketing fodder if the new lens isn't much better than a 600x1.4 (although i've no reason to think it wouldn't be).
A faster than f/5.6 would be monstrous. Plus a f/4.5 wouldn't benefit more with the teleconverters. It still would work in AF only with EF1.4X. And I cannot imagine an 800mm f/4. Unless it is sold with someone to carry it!
