Speedlites, Printers, Accessories / Re: Lexar CF cards FAIL - Sandisk?
« on: March 19, 2014, 03:06:37 PM »
I often read comments like; “used CF cards for more than 10 years and never had a failure”. Unfortunately if you have a closer look at the technology for memory today, you would quickly come to the conclusion that the older technology was more reliable than it is today, and why is that so? 

The frequency of card failures is increasing and the reason is that Consumer Grade Memory is no longer as robust as you would hope or expect.

Manufacturers of consumer grade memory have been on a quest to increase capacity, reduce cost and increase speed.  One thing they have done is shrink the geometries, from 40nm down to 19nm, and next is 15nm (changes about every 18months).  So by example a CF card today, using MLC NAND Flash only has a write endurance spec of < 3,000 writes.  When it goes to 15nm, endurance write will be down to 2,000.  Now if you purchased a cheap card, very likely it is TLC Flash and only has < 1,000 writes. 

With smaller geometries there are many downsides which requires modifying of firmware and circuitry.  The manufacturers are not open about the endurance write spec on their products.  However they comfort you with an offer of Lifetime Warranties, and for a product that has a Limited Life.  Small comfort when you lose 100s of photos on shoot, who cares about the replacement card – where are my valuable images!  NAND Flash has a limited number of writes and ultimately will fail with extended use.

Only advice I can give is look at Industrial Grade Products which use SLC NAND Flash.  These products have Endurance Write Specs  >2 million.  They cost more, but extremely reliable, slower performance, but not an issue for the majority of serious photographers.

+1

I hate to put the caveat out there because it seems so obvious - never leave home without at least TWO professional grade memory cards.

Now the question remains... what are professional grade memory cards and where do we find them?

1. I do not think that SLC memory is being sold today either in form of camera cards or usb flash disks or ssd disks. But I cannot be sure 100% so please feel free to correct me...

2 The reduction in cycles can be dealt with an increase in capacity. Only then the reuse count will be smaller (just like ssd disks)

3. Since I have 5D3 cameras I use double cards (with raw for both slots) for important shooting.

4. I also have a hyperdrive to backup cards after the shot but this does not negate the need for double cards...

For those trying to learn this stuff, I highly recommend these instructions:
http://rohidassanap.wordpress.com/2013/08/10/guide-to-using-dual-iso-mode-on-your-canon-5d-mark-iii/
Please IGNORE this instruction from the referenced URL:
4) Delete the CR2 files as the DNG files are just as good for adjustment.

Do NOT delete the .CR2 files. The CR2HDR.exe has been improved many times in the past so it will most probably get improved again. You may need to process your .CR2 files again...

These Magic Lantern disclaimers are about as unstable as ML hacks.

What's that supposed to mean?
Who cares?  I like it I use it. He does not like it he does not use it.

Definitely do not have a clue as to what Dual ISO is?


It interlaces a single shot with two different iso settings like 100 and 800, you then de-interlace it with a postprocessing program "cr2hdr.exe". The result is a boost in dynamic range with a minor loss of resolution on both ends of the histogram. Great for shooting moving high-dynamic rang scenes.

Magic Lantern is so feature-rich you really have to try it for yourself, good thing is that you can disable modules if you don't need them and hide menu options you never use.


Thanks Marsu.....yes...now I remember reading that when I read about the first hack into the Mark III firmware...I understand you completely.  OK...I will have to look into this more...I am still a little chicken..(bwack..bwaaaaack....LOL!)....but I am going to go to the website and read up on this and see if I want to load it up on my 5D III....that will also give you guys a little time to make the new hack more stable so that it is not... "cutting edge" stable!!!!  I think it is REALLY cool that you guys can do and actually do what you do...if that made any sense!
No worries, it works  :) 

For starters, I have used it on both my 5D3s to learn the shutter count  :)

I have checked bootflag removal too.

It is good to have ML back. I used to have ML permanently on my 5D2. However, I have sold it last month to fund a 2nd 5D3. Keep in mind that I introduced ML to the new owner and he got hooked with dual_iso just like me!

So I suppose the rumor of a new 100-400 has died by now ?
Be patient. There is a CR3 that there will be a similar CR1 rumor next year  ;D

It is fine on my 8GB SD card and I am pretty sure that it will work up to a 32GB SD card.

52
I will wait till it is more to at least the beta stage before I try out Magic Lantern on my camera.

Definitely a sound decision when in doubt, only problem is that the ml devs have no schedule at all for a beta or even release stage - all this would mean additional testing and documentary burden, and the resources are allocated to developing new features.

This is certainly fine by me as I'm experienced with ml and can code modules and patches myself, I just want to prevent disappointment if a "stable" ml with the newer features might take quite a while to arrive.
Greetings Marsu. ML is now available for 5DMkIII with firmware 1.2.3. Bootflag removal is now possible (finally).

Now, that's quite an accomplishment. For starters I used to find the shutter count of my new 5D3  :)

EDIT: Just saw your thread....

53
hello all,

I just found out the shutter count of my new 5D3. After taking enough pictures and playing with it the shutter count was 132.

So it was new after all.

I found out by installing Magic Lantern which became available for 5D3 firmware 1.2.3 with bootflag removal capability  :) :) :)

1.4 no question if loss of IQ is your primary concern.
+1, 1.4xIII by all means to get maximum possible IQ. You got your 70-200 2.8 II for this very reason I assume.

Lenses / Re: List of rumored lenses
« on: March 15, 2014, 07:45:51 AM »
It's interesting to see that the rumored lenses in 2010 remain as is in 2014!
;D ;D ;D

I made a quick experiment. I switched cards and now the image number jumped to more than 900.
So there is a strong possibility it is my doing. Anyway this has made me to try and check the camera as much as possible. Of course I did not test everything but I tested a lot. It is just fine. It is behaving exactly as my first one.

So I do not think there is a reason for return.
Another positive hint: The clock was unset.

So I will keep it  :)

Thank you for your responses.

P.S

hello,

having sold my 5D2 I bought a 5D3. I made some tests to check it but due to bad weather and work I did not have the chance to use it. So now I tried to test it again.

It works fine but I noticed 2 things:

1. There is a infinitessimally small dot on the glass of the back LCD. It is just a dot
and can be seen only when the LCD is off.

I mentioned it and I was offered an exchange.

However, since I will have to pay the courier I guess it will cost (with insurance) more than 50 euros.

Any suggestions? (since it is very very small and can be seen only when LCD is off)

2. The image counter seemed a little over 500 while I had shot less than 10. But I do not
remember whether  I had formated the CF I put in the camera before using it.

Could this be the cause?

They claimed that this is the cause.

If you bought the camera as NEW from authourized dealer, then you should demand the dealer to take the return/exchange at no cost. You think the 500shots came from Canon? or from returned customer?
True but:

1. They claim it was due to the card I put in and I am not sure it was empty at the first place. I think that I shot a few, saw that I didn't care about the content and then formatted it. I had no intention to check - the thought hadn't even crossed my mind since it was the 2nd camera had I bought from them and I also had bought a 500mm f/4L IS II.

In my next buy I will be prepared but for now how can I be sure that I wasn't at fault for this counter?
They aren't authorized dealers but they offered an exchange (and they gave a contract number of a 3 year guarantee).

2. Now if  I  return it on the basis of the mark they will at least laugh at me. It is practically a point and seen only when the LCD is NOT lit.

58
Thanks, I am thinking that it would be too much to return it just for that. And my 1st 5D3 was from them, it was (and is) just fine.

For me, it's all about pixel density. I have 20/10 vision..I can CLEARLY see the pixels. It's utterly horrid..

I'm at 20/15 w-o correction, and I can see the pixels in my EVF too if I want to concentrate on that. 

I have 20/2000 vision.... I can't find my camera without my glasses.....
;D ;D ;D
