Lenses / Re: New Samyang 10mm f/2.8 ultrawide! Looks impressive...
« on: December 09, 2013, 05:14:06 PM »
I bought the 14mm after reading the hype and it was awful.  Users also said it was EF, but it came with a note in the instructions stating that it was optimized for crop cameras and FF users should expect poorer quality.  That was a understatement.

What was awful if I may ask? My copy of the 14mm is great (beside easy fixable heavy distortion). I use it with a 5D3.

In german but you get the idea of the quality of UWA lenses by watching the pics:

EOS Bodies / Re: 5D MIII - Where should it expose?
« on: September 21, 2013, 06:22:15 PM »
The 5D MkIII meter, as all Canon cameras have for years, meters to 12% gray, NOT the 18% gray that is the normal presumption. 18% gray gives you a histogram spike in the middle stop of a histogram. BUT 12% gray gives you a spike in your histogram 2/3 stop below middle gray.

Your camera is working to specs and as it is intended. Some suggest the "underexposure" is due to digital captures being very sensitive to over exposure, but that just is not the truth, pre digital Canon's and Nikon's meter 12% too.

A more interesting question would be "why did the camera industry decide 12% metered scenes give a "better" exposure?" My answer would be that they considered the options and decided that gave more even and "correct" exposures more often than 18%.

How does this explain the brighter exposures of ross' and my (now sold) 7D?

Hi Ross,

thanks for asking this question! My 5D3 also underexposes, sometimes by more than 1 stop. I gave my body to the canon support twice because I thought it has a problem. Support told me that the body is OK as it is.
CPS is not aware of problems with metering. But there are a lot hits when you google for it.

I work around it with a user profile. Neutral and contrast -4, the other values are 0. This works much better imho.

Buy a white(!) water resistent textmarker. Use your 14mm in bright daylight and focus to infinity at f/2.8. Mark that point with the textmarker on your focus ring! In the night you dont have a chance to focus with that lens! (the infinity marker from samyang on the lens does not work).

EOS Bodies - For Stills / Re: My Canon 5D III went down today :((

Looks like the shutter broke to me.

How would that cause the image to step out of line in random bands ?

Looks like corruption in the card/reading/transfer somewhere to me.

If the files would be corrupt you would have some color/pixel distortions where theses bands end/begin.

- Use manual mode
- Dont use metering, it sucks with the moon. Use live view instead.
- ISO 100
- Use a tripod
- Switch off IS

Lenses / Re: lens calibration
« on: December 17, 2012, 05:53:52 PM »
If you have a 1Dx I wouldnt let Canon do the calibration. Your body allows AFMA for the wide and tele end. All values in between these ends are interpolated.

To find the best AFMA values get a license of focal pro. It is an excellent piece of software from reikan/UK. That way you can be sure that you really have the best calibration possible.

Hi everyone,

my question is ,

does anyone know what Canon "does" when they take both the body and lens for calibration?

Yes, I was lucky and was invited to assist in the calibration of my gear. Canon support first calibrates your camera body. They use their reference lens to calibrate the sensor plane of your body to match their lens. The calibration value is stored in the camera (You cannot see that value in the menu or anywhere else). After that they start to calibrate your lens(es) with the help of a lensalign like setup. These calibration values are stored inside the lenses. They can calibrate for the wide end and tele end and every step in between in case of zooms. Off course all AFMA values that *you* can set in the menu are reset to zero before the calibration and have to be zero afterwards.

I sent in my 24-70II since I noticed that it's not as sharp as my friend's copy (we bought them one week apart). I also mentioned that it's back focusing and that I've tried using AFMA but haven't got it right and would appreciate if that can be looked at too. To my surprise I was told that AFMA "shouldn't be used" except for "special" cases. I said, that I've been doing it all the time with all my bodies and lenses. After I sent a complaint to the person in charge of after sales/ warranty, I got a call saying that the "bad focus" is because I set AFMA and that it's stored in the ROM of the Lens..
I dont know if this was a communication/understanding error on his part as Canon really stores these calibration values in the lens. That is something the end user cant do. AFMA via the menu is different as it is a user configuration thing. Perhaps he mixed that up.

My first words "Bull $hit" I couldn't help myself. It was obvious the person talking wasn't technical. I asked, so you mean to tell me that if I set AFMA for the 24-70II on my 1DX those settings are stored on the lens.. Reply.. YES.. .. I explained why this was complete Bull$hit.!! by asking "so that means, I can't use this lens on my other camera bodies.. SILENCE..

Long story short.. I was asked to send my my 1dx which they just "reset" ALL my AFMA settings and they re-flashed the ROM on both the 1dx and 24-70II  and asked me to "retry".

I just finished testing using lensalign, (didn't feel like using focal pro). my manual testing resulted in (-4,-4).. Same as what I got with Focal Pro on the first day I got the 24-70II.
Well, Canon support is sometimes lazy and they just do nothing with your gear. They just send it back and pretend to have done something.

Any thoughts.. the CPS guy I spoke to wasn't very helpful.. He kept insisting that I should use the multicontroller/joystick to "SELECT the focus point"
Very helpful indeed...

you can imagine my frustration explaining DOF and that the little red square that's on the object tells me where I focused, and that object isn't sharp, hence SOMETHING is wrong. I asked him, do you take photos, he replied yes, I said I'm sorry but you're no photographer.. kinda mean, but I couldn't help it!!!!

Ok Rant over!!!!!!

I feel your pain. If you need help and they treat you like an idiot.

EOS Bodies / Re: Canon 5D Mark III - Price Drop Details
« on: October 30, 2012, 03:20:38 PM »
Is the price drop really from Canon, or is it from retailers? I would be really curious to know whether Canon themselves is actually getting less per unit with recent drops to $3100 and $2900 and such, or whether it is simply that the initial 5D III Feaver has warn off? That all the pre-orders and early buyers who were anticipating the 5D III for years and were going to get one regardless are now done, and now retailers are trying to attract the more careful, price-wary buyers? Canon doesn't get $3500 a pop for each 5D III sold...they get something in the mid $2000 range. It is the retailers who are trying to build sales...and I assume that for all the prices down to the low of around $2700 I saw recently, they are still making a profit...as is Canon.

I got my 5dIII for 2500EUR from a small shop. If you substract the sales tax of 19% you are at 2025EUR. The shop wants to earn something as well as the distributor. So my guess is that canon is getting something in the mid 1000EUR/$ (because EUR=$ for some unknown reason) range.

The CR guy can see which country I'm in because of my IP address. But I can block or hide my IP address from any internet Proxy Server (some hackers can actually have a different IP address display e.g. to show that they're in New York when they're actually in Poland!). So your GPS idea would not work - hackers would find a way around it.

Secondly, why on earth would Canon Inc. or any other consumer electronics manufacturer wish to sell a 'dumbed- down' product for more money in Europe than a superior one (in capabilities) in the USA for less money (as prices there are already cheaper even accounting for FX rates + local taxes)?

Apple Inc. does not have a British iPhone 5 that is inferior to a Norwegian (non-EU) iPhone 5, nor would they ever consider doing that to their product lines. Can you imagine an Australian iPad 3 have lower resolution than an American iPad3. The 1DX is the 1DX no matter where you buy it in the world, and that is how it should be.

...

If a hacker bypasses a GPS (VERY DIFFICULT), then it's on the camera owner, not Canon.

...

Bypassing your GPS check is everything but difficult. You could build a device that sends (usually via serial protocol) faked GPS data to the camera (e.g. location is NY). The format of the GPS data is well known and even if Canon use a proprietary format then it should be easy to sniff the serial communiacation and decode the format.

And if that doesnt help you could patch the firmware and remove that part from the code that does the decision whether you are allowed to use extra functions.

sorry, but that doesnt work.
