EOS Bodies / Re: Are we suckers, or smart business people?

If you're going to compare, you have to be fair:
...
* Nearly 1 stop better ISO (that puts it level with the d3s and virtually at the new d4, so it would seem)
...
The only thing that **hasn't** changed much is the amount of MP and DR!

The ISO improvement appears to only be with in-camera JPEG output.

That means that there is non improvement in the sensor itself and thus no improvement for people that shoot raw.

Thus, with the exception of fixing the banding problem with the 5DII, there has effectively been no improvement in the sensor from the 5DII to the 5DIII. Thus there is little to no improvement in image quality for anyone that uses the 5DII today to shoot raw.

PowerShot / G1X Review - The G1X is a hermaphrodite
« on: March 13, 2012, 10:42:29 PM »
http://www.luminous-landscape.com/reviews/cameras/canon_g1x_field_report.shtml

"Can Canon continue to be content to produce warmed-over versions of last year's DSLRs, ignore the mirrorless segment, and produce compromised crossover products such as the G1X? I sincerely hope not, because they are a great company which has hugely contributed to the photographic industry over the years. It's just that at the moment the still camera division at Canon seems stuck in about 2005. It took a palace revolt that same year at Nikon to give that company back its mojo. Will the same be required at Canon in 2012?"

D800 is going to be challenging to use hand held because there are increased shutter speed requirements due to the smaller pixels.

Perhaps im not sufficiently knowledgeable but i highly doubt this it true, according to your theory that means that in the same scenario you would shot a d700 or 5D1 with 1/40?

Let me answer that in another way.

With the 5D2 and an unstabilised lens, for maximum sharpness, it is recommended to use 1/2xfocal-length, compared to the traditional 1/focal-length for 35mm film.

The requirement in speed is because the angular size of the pixel decreases meaning that fine detail can more easily be blurred.

The higher the MP count goes, the more exacting the requirements are in technique.

EOS Bodies - For Stills / Re: Chuck Westfall & the 5D Mark III

AH: Canon has indicated two stops improvement in high ISO performance relative to the 5D Mark II. We understand this figure refers to in-camera JPEG files with noise reduction. Approximately how much of an improvement in high ISO performance or low ISO dynamic range is expected in RAW (CR2) files when using the latest Canon DPP software?
 
CW: These figures are not being disclosed, but of course they will be lower than the noise reduction achieved with in-camera JPEGs and EOS Movies.



I believe even 1 whole stop improvement is pretty good advertisement but since CW responds to the question very very politically, I believe DR of 5D3 is probably on par with 5D2. It's so obvious that I'm not even looking forward for any tests or in-depth reviews...

Such a shame...

Yup, me too.

There is an arrogance, if not actual contempt, shown for the customer in this interview. The answer about f/8 focusing borders on flippant.

"CW: This request has been conveyed for consideration."

I must have read another article because I didn't detect any "arrogance". The fact that they are listening to their consumers and considering f/8 is far better than him flat out saying no. You have to keep in mind that he has to be careful with what he says and promises because Canon customers would want his head if he went back on something he said, no matter what the reasons were.

I agree, I don't read arrogance here, more like a "We f**ked up, but we're not going to admit it so ask me something else."

EOS Bodies / Re: 5D3...why only usb 2.0?
« on: March 13, 2012, 07:16:12 AM »
Some guesses:
- power requirements
- internal heat/noise generated
- USB 3.0 chips were not available at the time Canon started the 5D3 design
- USB 3.0 chips could not be included into the 5D3 without pushing up the price further

My wife and I started up a photography business last year.  I'm currently in the process of getting her a camera body.  We primarily shoot family portraiture and are moving into weddings this summer. I currently have:
...
I do have the mark 3 preordered but damn the D800 is tempted... I could sell everything and start from scratch... I would lose some money yes, but does Nikon have equivalent primes as Canon does?

The D800 may allow you to print larger if you are doing tripod shooting for family portraits.

However when it comes to weddings, the D800 is going to be challenging to use hand held because there are increased shutter speed requirements due to the smaller pixels. For example, with a 50mm/1.4 on both the 5D3 and D800, you'll need to use a faster shutter speed on the D800 to reliably obtain sharp photos when hand held than you would with the 5D3. The 5D3 may deliver sharp results at 1/80 but expect to need 1/100 or 1/125 with the D800 in the same circumstances, etc. IS will help to some extent. The other side of that is because you need to shoot at 1/125, you'll need a higher ISO than you will with the 5D3.

@ dilbert & Zim
I've thought about adding an option concerning sensor features (such as snr, color & DR) but i decided against it cause there would be people, saying that "well we dont know nothing about  the sensor and it might as well be etc" and they would have a point, although the fact that Canon hasnt been touting about it in their marketing is kinda disheartening.

Well, lets look at the poll another way.

The poll doesn't offer any option for "better image IQ" unless you subscribe to the "more megapixels = better IQ".

EOS Bodies - For Stills / Re: 5D3/5D2/D800 DR plotted

Hard to compare a D3X against, say, a 1Ds3 or a 1DX  or even a 7D against the D700 - because as you say they are all Nikon

Right, but the point here isn't to compare a 1Ds3, 1DX or 7D but rather the 5D2 to the 5D3 and both of those with the D800. People want to know if the 5D3 is better than the 5D2 (and if so, by how much) and how the D800 and 5D3 compare.

Regardless of the numbers, what is quite apparent is the dramatic DR drop off at high iso.

From the graphs then we should be less concerned about the high ISO performance and focus our techniques on the low (800 or less) iso images

From my own experience the drop off is about right and I aim for 400 or less wherever possible By iso 3200 the DR seems to have dropped off by 1/3 to 6 to 7 stops.

I have ignored the D800 and 5DIII numbers as they are just estimates (and this site has a Noink bias). The D3X seems to do the business up to iso400 and falls away very quickly

The numbers are estimates because pre-production models of the camera have been used by imaging-resource, not because the numbers have been made up.

I think it is wrong to say that the website has a Nikon bias - rather the cameras that are of interest to the person who maintains that website all happen to be Nikon.

Found a 5Dii on my local CraigsList for £800 today - is this too good to be true?

BTW - also shipped with a free Lowepro bag

Never buy anything from Craigslist unless it is cash in hand and the goods are exchanged in person for cash.

If they have to post it to you or you have to send them money, skip it and move on to the next ad.

"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.

The D800 (purple line as you describe it) has data points (inverted triangles) at ISO 50 and ISO 100, for which there is no data according to the quote.  Not sure how you can state ISO 100 is indeed not present on the graph?

There are two entries for the D800 and two graphs.

One for the D800 and one for the D800E.

The D800E does not show anything for ISO values under 200.

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.

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.
