EOS Bodies - For Stills / Re: 5D3/5D2/D800 DR plotted
« on: March 10, 2012, 09:51:48 PM »
I went to the site, but there was no image, it said there was no data for the D800(e) below ISO 200, so I'm wondering whe the chart shows a curve belowISO 200 attributed to the D800(e)

(e) denotes estimated.

So we have a curve made up by a Nikon site that is faked?

Not something I'd want to spread around.

It's not faked.


"There is no data yet for the D800E below ISO 200." From the page linked to.

Yet, they show a curve below 200.  I guess you would call that curve a creative estimate?

The graph is correct. The sentence you quote refers to ISO values, not their presentation on the graph.

Thus "ISO 400" is not below "ISO 200", it is above it.

"ISO 100" is below "ISO 200" and indeed is not present on the graph.

EOS Bodies / Re: 5D3 same max dynamic range as the 5D2???
« on: March 10, 2012, 04:29:34 PM »
The 5D3 and D800 are pretty much comparable, but only at ISO800 and above.. Below ISO 800, the D800's DR is heading sky high, setting a new record.

Bill Claff, whose site this is from, is a long-time fervent Nikon guy; and these graphs are based on estimated values for both the D800 and the 5D Mk III.

Big pinch of salt in order here...

As long as the methodology used is the same across all cameras then it is valid to compare cameras with.

The numbers in his graph don't agree with DxO (for example) but the disagreement is roughly the same whether the camera is Canon or Nikon.

I'm not sure what's got into digitalrev, but they've put the price up on the 5D to $4000!! That's only $200 less than Teds, which kind of makes the whole buying grey to save pointless!

I think I'll pick mine up from Camera Pro, will give them a call during the week, has anyone bought from them before that doesn't live in Brisbane? (I'm in Melbourne) Any idea on what you would do if you're interstate and had a warranty issue?

Cheers!
Sam.

Demand.

They can keep putting the price up until people stop buying from them instead of other places.

Maybe they didn't realise how many people would order from them and now that they realise they only have to undercut Teds by a smaller margin, they're doing so because nobody else is competing with them on a low price.

The URL is an interactive graph.

You need to click on the cameras on the right for them to show up on the graph.

It is all Nikon except for the 5DII and 5DIII.

EOS Bodies / Re: Canon Teases Exclusive Screening at NAB 2012

A strange one this...

The C300 is top of the line cinema, so the new DSLR, has to be somewhat inferior to it - especially if we are to expect it to be cheaper.

The 5D3 is basically a merging of the 5D2 and 7D cameras and lines.  The 1Dx is now the sports action camera, so the space remains for the "Studio" version of a DSLR with a full-featured video spec, in a 1D-type body...  What with Nikons's D800, it would not surprise me to see a very high resolution stills camera with high-res video...

Lets hope that Canon takes on a similar direction to Nikon and does the "studio DSLR" in a normal body rather than a 1D style body.

The graph is interactive and allows you to compare 5D2 (green under/close to orange) with 5D3 (orange).

The 5D2 and 5D3 are the same until roughly ISO 800. Both start at around 9...

I've included the D800 on this graph (purple line) starts at almost 11 and the D3X is directly under that (green line) starts at around 10.5.

EOS Bodies - For Stills / Re: 5D Mark 3 Queue @ B&H
« on: March 10, 2012, 11:49:05 AM »
I placed my order on March 4, 6:30 am.  Where do u think I am in the pre-order list?

Also, I find it hard to believe that canon would release a new camera & have just 1000 inventory to a store like b & h.

Depends on how often B&H will receive shipments. Maybe 1000 a week for ...?

I would expect that B&H will get theirs when the train arrives carrying the container from whichever west coast port receives it (probably Seattle area.)

EOS Bodies - For Stills / Re: 5D Mark 3 Queue @ B&H
« on: March 10, 2012, 11:43:23 AM »
I pre-ordered the camera at approximately 12:20am EST the night that it was announced at B&H. I called up B&H today and asked them where I stood in the pre-order queue. He couldn't give me an exact answer, but he indicated that I was in the first 500 pre-orders, but in the latter half (so around position 350-450). He also stated that the current queue has ballooned well past 10,000 pre-orders (but again, didn't give me the exact figure).

I wonder what percentage of that 10,000 is international sales looking to buy at US prices rather than their local price?

I can believe I'm saying this but i agree with Axilrod  :P

Remember that the 4K DSLR will not be a good stills camera as such.

Its resolution is 3840×2160 (8.3 million) pixels.
Thats what modern "4K" represents.
NOT 7680x4320 what you think would be 4K.

That remains to be seen.

Whilst HD TV (1920x1080) is only a 2MP picture, the C300 has an 8MP sensor to deliver that because of the Bayer sesnor pattern.

Thus it is not beyond imagination for Canon to deliver a 4K DSLR that actually has a 36+MP sensor.

The price of $3500 would be justified to me if...

* there were 13 or more stops of DR in the photos and nothing less
* there was 1 (preferably 2) or more stops of improvement in signal to noise from ISO 100 through to ISO 6400
* USB 3.0
* clean HDMI out at 1080i or better
* better sealing on the buttons, etc, to keep out dust and moisture

As long as the number of megapixels was at least the same as the 5D Mark II, I'm not particularly concerned.

What I want is better quality photos for pulling out detail from dark regions and less noise.

EOS Bodies / Re: Is this the Canon 5DX?
« on: March 08, 2012, 07:43:46 PM »
Has anyone loaded the picture up into photoshop and tried adjusting the various levels to see if there's any easily observed evidence of cut-n-paste?

EOS Bodies / Re: Where did the new Canon 5DX topic go to?
« on: March 08, 2012, 07:29:13 PM »

Looks very similar to me in terms of the lighting although I spose Canon could have some standardised setup.

Or rendered both images with a computer as they do with lenses?

FWIW, I made a similar observation with the new prime IS lenses (same reflection patterns in the lens' front element) and both turned out to be true.

Personally, I think the 5D mkIII specs suit the needs of landscape photographers. Or, at the very least, it suits my needs as a landscape/nature photographer.

 My reasoning is thus: I'm often shooting in the morning or evening (golden hour) in low light at an f-stop between f/8 and f/11 and quite often I'll be using various filters from polarizers to graduated ND filters. This means that in order to get decent shutter speed I generally have to crank the ISO up, but I want as clean an image as possible. So the 5D mkIII's improvement on the mkII's ISO will be a great help.

Here's a tip: get a tripod and shoot at ISO 100 more often.
