Has anyone tested any of the Leica WA lenses on the 1DIII? If so, what lenses work?

If not, I would love to know if there is a safe routine for testing lenses that MIGHT not clear the mirror. Can anyone speculate on possible miror damage or suggest a safe routine?

The pixel-pitch of the 1D-III is definitely smaller than that of the 1D-II . . it has to be, as it has more pixels in it for the same sensor size.

However, because Canon reduced the "wasted space" between the acutal light-collecting photosites, they were able to utilize the same size photosites in both cameras.

Additionally, Canon worked some magic on the microlenses that collect the light for the photosites, resulting in better light collection.

Thus, the dynamic range (signal to noise) of the 1D-III is better than that of the 1D-II, even though the pixel density has increased.


Yeah, it's important to note the definition of pixel pitch. From the center of one pixel to the center of the next one in the row. One sensor could have 50% wasted space, another could have 10% wasted space. If both sensors had 10mp on an aps-H sensor, the pixel pitch of both would be the same.
I believe better ccd sensors can reach 90% coverage. But these sensors don't have all the good NR stuff on the sensor.
There's a light collection efficency - the quality of the diode (?), the efficiency of the mirrors, and the amount of space between each "collector". So we really don't know much about what's going on from knowing the pixel pic spec.

But the 1D MK III is a 0.6 mm shorter in the horizontal direction, for a total loss of 2%. I want those 0.2 megapixels back!

Could be, but the 4GB and 8GB Extreme III are also nearly identical on the Mark II and the 1Ds Mark II, FWIW.

He said he was using 4GB Extreme III's in both cases, so I was even more surprised to see his results.

Yes recently purchased (from mydigitaldiscount) 4 GB Sandisk Extreme III...CF and SD versions.

I really don't understand it myself. Rob Galbraith was implying fast SD write times. I'm sure I don't have anything odd set in the camera to cause such a discrepancy in CF vs SD write times (about 2X slower). I am using "standard" vs "multiple" for the card write selection, and I have the preview set to display the image from the CF card when both are written to. If anyone can think of something I might have set wrong that would cause such a drag on the SD times, let me know. I formatted both cards prior to test.

I know I could have done the test a lot better, I apologise for that, still it does give an indication of general trends and what clearing speeds, bursts to expect. The most puzzling thing to me is if you want to use SD cards, you'll pay for it, but it's not much more hassle just to write to BOTH formats at that point. Strange, no?

It's not that puzzling to me.

Basically, the CF is so fast (compared to the SD), that once you're limited by the SD card, the camera doesn't take all that much longer to ALSO write to the CF card.

That's fine — but why is the SD slot so much slower than the CF? I thought it was supposed to be the other way around...

Yeah, looking at RG's tables for the Mark IIN, with even older series cards, SD beats CF by a noticeable margin in raw speed for both JPEG and RAW.

With my 1DIIN, SD cards of equivalent type, i.e. both Extreme III same capacity, were faster than CF by some amount at clearing the buffer. I no longer have the specs, but there was a noticeable difference. Canon specifically made mention in the white paper that the SD interface had been improved a greater amount than the CF interface, so in light of the faster SD in the N (confirmed by several other tests available on-line including the RG database), it is puzzling why the SD is now MUCH slower. I no longer have any non-HC SD cards, so I wonder how much of a role the known "slowness" of SDHC cards is playing here. Just out of curiosity, I just did a quick test as well.

Using M mode, 1/500, ISO 100, body cap mounted, high speed drive I held down the shutter till the second click after the pause and then hit the stopwatch at that point to just time the buffer clearing. Cards used were a Sandisk Extreme IV 8GB CF and Sandisk Extreme III 4GB SDHC. In both cases the total frame count was 45, which makes sense given the lack of information.

Again these times are for the buffer clearing from the time the last of the 45 frames was shot:

Extreme IV 8GB CF 36 seconds till light went out.

Extreme III 4GB SDHC 1:08 till the light went out.

I've been playing around with the camera, had hoped to do some shooting, but have preety much spent the night getting familiar with the controls and CF's .

I was a bit thrown off by some of the differences between the 1D2N, but for the most part, i find the layout much better, in a lighter battery (with a great display about battery life).

I still do have some questions, I'm not sure if someone has already discussed these and feeling a bit to lazy to go through 14 pages to see if these have been discussed or not.

First o ff, i just purchased the 5D, and like how the multi-controller can be used to select the AF point. However, with the 1DIII, it appears that the IDIII can only use the multi-controller for a pre-registered point - is this correct, or did i miss something in the manuall While talking abou the 5D, i also have to say i find it very frustrating that the Depth-of-field button on canon's 1D series and consumer cameras are on opposite sides. It took me the past month to get used to the 5D's being on the left side (after selling my 1DIIN), now it is going to be even worse having when i'm working with both bodies).

The other question i have around AF CF's, is that, when the AF-Start button is used (when "2" is the option selected for CF IV-1), it seems that even 5-6 seconds after taking a shot, the IS on my 24-105 is still working. Is this normal Is this bcoz of the settings in CF IV-12 The operation does not seem to be the same as CF 4-1 in the 5D (i believe the 1DIIN, the 1v, EOS 3 and A2E functioned the same way as the 5D). I had thought the only difference would have been that their is now a dedicated AF-ON button rather then using the * button.

I also had a question about CF III-15. I find the "2" setting confusing (using the set key for mirror lockup). I had actually liked having the "C" mode in the 5D, where i could quickly setup a shooting preference that had mirror lockup and other settings pre-selected. I know that the 1DIII does have the thre pre-setttings available, but unlike the 5D, where you just change the shooting mode to "C", with the 1DIII, you still have to go through the CF menu options to select one of the three registered settings. It would have been nice if you could have selected the pre-sets using the mode dial (certainly more useful then having the "P" - program setting).

Other custom function questons i have are regarding:
CFII - 1/2long exposure noise reduction / high ISO noise reduction - are thse actually recommended, or is it better to use other programs for NR


Another question i've got is the transferring images from the camera to the personal computer. I've always used a card reader. Is it actually faster transferring files directly from the camera

ANyway, those are just some of the initial questions and things i don't like abou the camera.

On the plus - I love the addtiional customization. I am really going to have to play around with a lot of the AF custom functions in particular. I lalso ove the sound of the shutter - the silent mode is considerably quieter, i don't know if it is Elan quiet, but probably the quietest one series camera ever. I also like the lighter/longer lasting battery and more precise battery indicator, as well as the control layout - it jwill ust take a bit to get used to - probably more then going from the 1DIIN to the 5D. I'll probably also love the larger LCD, but just taking trial shots to get used to the camera's controls is not enough to judge the quality of the LCD at this point.

anyway, i can't get to get more used to the camera so i can put it through some actual real world shooting.

A final note before i call it a night, i seem to remember that there was some sort of cheat sheet of custom functions that came out with the 1DIIN or 1DII. I can't remember if i saw it on a canon site, RG's site or some other source, but it was a quick way to get used to some of the custom functins, i'm hoping something similar gets released for the 1DIII.

It's mentioned briefly in this quote from http://www.robgalbraith.com/bins/multi_page.asp?cid=7-8738-8908-8948


"Media management The EOS-1D Mark III has about all the options one could imagine for storing pictures on memory cards, and it does so faster than any previous Canon digital SLR too. CompactFlash write speed is approaching 11MB/second with the fastest cards in our testing, and well over 14MB/second with SD. The camera doesn't support UDMA, so it doesn't take full advantage of the speed possible from cards like SanDisk's Extreme IV and Lexar's 300X. Nevertheless, it is the fastest writing Canon (or Nikon) digital SLR we've tested."


And there's also some timings with CF card here:

http://www.imaging-resource.com/PRODS/E1DMK3/E1DMK3A6.HTM

This was all with pre-production cameras.

One small, annoying issue that I've noticed: If you're using two cards to record images - in my case, raw to the CF and JPEG to the SD - and then you want to delete the images on both cards. The "delete all images from card" function uses the card which has been set to "display". You can't select the card to use for erasing images. To erase the other card, you have to go back into the menu system to select that card for display and then go back to the "delete all images function". In a sense, I suppose it's a protection measure - you can see the images on the card before you go about erasing them... but still...

I'm not really fussed about it. The camera is such a joy to use. It's a fantastic all-rounder.

Price inflation?
What prices has been paid for the MIII? B&H shows $4999. Other sites show $4799-4999.

Are they being greedy?
