Canon General / How to understand DxO scores
« on: June 08, 2012, 11:48:51 PM »
This story was published at the beginning of 2011 but it should serve to illustrate why the DxO scores are useful:

... as they tell an important story (once you get past the fanboyism.)

Site Information / Sticky topics at the top of the front page...

I think these are being over done.

For example today, I go to the front page of canonrumors and the top article is the "Preorders" thing and not the announcement of the 650D.

The preorders thing was there yesterday, today's news is the 650D...

If I see that the top story hasn't changed on the front page then I'm very unlikely to scroll down... don't know about others...

EOS Bodies - For Stills / Canon EOS 650D/T4i announced
« on: June 08, 2012, 12:36:01 AM »
The news is now up on dpreview with all of their usual samples, etc.

http://www.dpreview.com/previews/canon-eos-650d-rebel-t4i/

From the front page of their preview:
The EOS 650D has a new 'Hybrid CMOS' sensor that now includes pixels dedicated to phase detection autofocus (in a similar fashion to Nikon's 1 J1 and 1 V1 mirrorless cameras).

... so either the 650D does have a new sensor or they're using it in new and different ways.

94
For portrait and landscape, the D3200 scores 24.1 and 13.2 respectively whlist the 5D Mark III scored 24.1 and 11.7. Of course the 5D Mark III whips the D3200 in low-light ISO (sports) but otherwise the scores are the same (81) for both cameras.

So it just goes to show that APS-C sensors aren't necessarily as useless, even with higher MP counts. Unless you need that low-light/higher ISO.

As DxO points out, 5 of the top 10 cameras on their website are now made by Nikon.

Got to wonder if Canon will be able to deliver a crop sensor that comes anywhere near that.

PowerShot Cameras / Will the S100 successor have a larger sensor?
« on: June 06, 2012, 08:10:30 AM »
Will Canon increase the sensor size of the S100 in its successor to deliver more MP with better IQ rather than just more MP?

EOS Bodies - For Stills / DxO compares the 5D Mark III with the D800
« on: June 05, 2012, 05:07:12 AM »
Even if you think DxO don't know anything and their testing is rubbish, you should have a read of this as they go into more detail about their testing, specifically the signal-to-noise testing:

EOS Bodies - For Stills / Weather Sealing for EOS cameras
« on: May 24, 2012, 03:15:12 AM »
Before the digital era, the top of the line film EOS camera was the EOS 1v. It was UAS$1899.
With the battery pack booster, the pricing was around $3000.

The EOS 1v was marketted as being waterproof.

The EOS 1v was released just over 11 years ago, in February 2000.

In 1998, Canon brought out the EOS 3 in 1998, for around $1400. Today it is $1699.

If you allow for a 3% price rise per year since 1998, that would end up at around $2055 (EOS 3) and $2788 (EOS 1v). If you want to argue that time should mean that things are cheaper, then...

So quite clearly, weather sealing does not mean a camera needs to cost > $3000.

But another way to look at this is that the difference in a digital camera that shoots 6fps at 22MP (5D3) and a film SLR that shoots 10fps (1v) is $1800.

How much of the $1699 is electronics for film that can be ripped out?

If the cost of that was ~$200, then the "digital" part of the 5D Mark III is worth $2000 out of the $3499 price tag.

EOS Bodies - For Stills / 5D3 weather sealing...
« on: May 20, 2012, 01:40:34 PM »
Has anyone splashed their 5D3 and had it keep on keeping on?
Is it fully weather sealed with o-rings for everything?

From comments on the web, it seems that the Nikon D800 is not fully weather sealed as it is missing rubber o-rings in various places (battery compartment). Can anyone that has used a 5D3 and D800 comment on that?

5D MK III Sample Images / Moire?

Does anyone have a CR2 (raw) file that shows moire at 100% magnification?

... Canon have split the line and we're yet to see what they can do with video in a 5D sized body?

EOS Bodies - For Video / C300 in professional use...
« on: April 14, 2012, 03:45:06 AM »
A couple of URLs with stories from pros...

http://www.hurlbutvisuals.com/blog/2012/04/dueling-canon-c300-and-arri-alexa/

... this one is interesting because there are quite a few comments and discussion about how to dial down the detail of the C300 with how it renders skin. They don't want to capture and broadcast all of those pimples, etc.

http://www.hurlbutvisuals.com/blog/2012/03/the-canon-c300-on-an-el-pollo-loco-spot/

In this case, it is a story of the C300 being used to shoot a promo. In case you were thinking that the C300 was expensive, do an inventory of all of their other expenses - especially post. The C300 cost will be a once off that will be amortized over many different shoots whilst other costs (gennie rental, gas, post, etc) will be re-occurring.

EOS Bodies / How to distinguish the Cinema 1D?
« on: April 13, 2012, 04:33:55 PM »
I like C1D because it matches up with the C300 and C500. 1DC makes it feel too like a variation of the 1D series cameras, although that it is. Tough call!

EOS Bodies / How about an app store for EOS cameras?
« on: April 10, 2012, 05:08:22 PM »
Now that cameras are dedicated imaging computers, why not have an app store where you can download certified apps for your camera that are written by 3rd parties?

That would make it possible for people to write their own zebra stripes app or develop their own apps to deliver better bracketing support ... - make it possible for the camera to support more features without Canon having to do all of the research, development and testing.
