Reviews / Re: Why I Chose a Canon EOS 6D over a 5D MKIII
« on: February 09, 2013, 01:28:30 AM »
This thread reminds me of  Porsche Boxster vs 911 owners:

Boxster Owner (6D):
1. It's lighter due to use of high grade polymers.
2. More nimble easier to handle
3. It's convertible so I see better, especially in the dark (high ISO)
4. Easier on the wallet, cost less, better value
5. This car fits ME perfectly!  I love it!
6. Most important of them all, I don't need all that features

911 Owner (5D3):
1.  "No comment"

911 Turbo (1DX) Owner:
1. While slapping his hand on the forehead: "Damn rookie, must be his first sports car (aka to FF)"

An entry level FF NEX (NEX 9?) with same sensor for $1799 to compete with 6D/D600..WOWer  ;D

So why is the difference between this 2 shots not that big??

ISO100, f/5.6, 1/4s
To me the Nikon pic looks a bit washed out or OOF or something. The Canon one looks crisp. May be slightly more black in it but crisp.

Agreed.. the Nikon looks a little washed out compared to the 6D.. probably due to less contrast.  But the 6D underexposed compared to D600 in this picture.  If you look at the bottom of the images at the camera or the shadow around the front of the car.  There is virtually no shadow between the car and book (brighter) and the camera black accordion area is more pronounced on the D600.   Either the Nikon overexposed or the Canon is underexposed or perhaps DR?

This article suggests that the Canon 6D images are darker by about 1-2 stops vs. other Canon and Nikon cameras with identical settings (at least with long exposures).

I'm skeptical about this, and currently the article did the tests only with jpegs - so it's entirely possible this just has something to do with the jpeg engine or jpeg settings.

However, I was wondering if anyone who owns a 6D has seen this issue?  or can confirm this issue does/doesn't actually exist in the RAW files?

Canon has their own iso compared to Nikon, if you look at I-R you can se that Canon sensor sensitivity /meteringsystem  is not like Nikon. IR test target and middle  grey shows that Nikon can be  exposure up to 1 stop shorter  , if Nikons metering and sensitivity allow us to exposure 1/1250sec  Canon must be exposed 1/760sec, almost a  1 stop more.
This is a problem, if we compare noise/resolution etc at a given iso.
Example, Canon is more like 6400iso (time/f-stop) when Nikon and Canon are exposed after 12800iso because Canon  need to be exposed longer  1/760sec instead of 1/1250sec as Nikon
So if we will compare sensitivity, middle grey, stops up to clipping , Canon are almost 1 stop less sensitive compared to Nikon if we are using same time / f-stop and  middle grey are placed in the same way and up to clipping. Therefore I always are little bit curios when people are comparing cameras and for example high iso -are they exposed after the same settings time/f-stop ??
here is d800 6400iso and 5dmk3 6400iso

I see.. very interesting.  So should we prefer a camera with higher sensitivity for a given lumen?

Well, as somebody in the comments section of that page mentioned, if its underexposing, a long exposure (like the 30 seconds in the night shot of San Francisco on the link) will exacerbate the issue.

The test shots on those links were shot at 1/4 sec.

I am pretty concerned about this issue, I'm really hoping it's just the factory settings, like Auto Lighting Optimizer being turned on.

My T2i overexposes constantly, especially with my 28-135mm. I'd really like to be able to use aperture priority mode without having to mess with the EV settings constantly.
I oftentimes shoot with my 60D overexposing by 0.3 stops (sometimes 0.6), and it has never annoyed me. I just set it to +0.3 and leave it like that.
I did the same with my 60D.. +.3 or +.5

From what I see in various comparisons so far, the 6D is definitely cleaner but it also loses details as ISO increases.

you can open the RAWs with Infraview.  Maybe Rawtherapee works too.

And the winner is.........

                           Nikon           Canon
Sensor  :                1                    0
Lens      :               0                    1
Body      :               0                    1
Flash     :                1                    0
Metering:               1                    1    (tie)
Fan        :                0                  0     (we argue so much none of us deserve any points)
Total     :                 3                   3

Winner cannot be determined at this time.

I don't know, the 600EX-RT is a damn good flash.

Have to agree there. The latest round of flash tech from Canon is pretty mind bowing. I'd give that point to Canon myself.

So I guess the winner can be determined at this time.    ;D ;)

Thanks Razor,  you just extended this thread for another 14 pages.    ;D

If AF in Video is important to you, then look at T4i.  No other Canon DSLRs have AF in video except for T4i.   Even then, the AF in video for T4i is still slow and it hunts.  You might as well us manual focus.

7D better for sports but it is twice as much as 60D.

EOS Bodies / Re: What to buy...?
« on: April 29, 2012, 03:21:23 AM »
7D also have the same sensor so the IQ is also the same.  You might need to move to 7D for action/sports because of AF, weather seals, AF micro adjust and 8fps.  If you subjects move a little then maybe a 60D is enough since the AF and fps is better  T2i and T3i but not as good as 7d.   T2i, t3i, 60D and 7D has virtual identical low light performance.  T2i has the smallest body, then t3i.  60D is a noticeable jump in body size from T3i and 7D  a little bigger/better than 60D.  60D and T3i has swivel screens.

Go to Best Buy and try it out.  They should have all 4 on display for demo.  they even have the 5DM3 on display as well, behind glass though.

I hear rumors that T2i might have a very slight edge in IQ of the 4.  Don't flame it... just rumors.

My personal OPINION for what you do (non sports) get the 60D and save for FF.  If sports, then 7D unless you can get additional permission/budget to go FF (5DM3, 1Ds)

EOS Bodies / Re: What will be the response to the D3200?
« on: April 22, 2012, 11:45:35 PM »
Judging from the micro IQ difference between M2 and M3,  the t4i isn't going to change much.  It will even have the same AF with 1/2 stop iso improvement.  iq will be the same at low Iso.  Heck low ISO iq has not changed since 450d. 
Common canon!

I've heard that there will be some announcements on the 16th.
I have been waiting for the announcement as well, I am so curious. It is so frustrating waiting. I was originally told that it would be released in February, then March an now it's April.

From what I've heard, there will be minor upgrades. Most that don't have anything to do with the quality of pictures (such as wifi capabilities and touch screen). I have decided to wait, even though I am very impatient. I figured that if I wait and I like the T4i, then I will thank myself. If I wait and find out I hate it, I still win because the T3i will become cheaper.

I hope you sort everything out. Good luck :)

Interestingly, the Nikon D3200 will be announced during this timeline as well.  Hopefully we will get better news in two weeks.
