and low noise.

Then why is it iso 400 on all cameras (crop, ff) and what about the famed high iso capability trumping the Nikon low iso trolls :-p ?

Really, there's no excuse I could imagine for this broken auto iso giving the user no options at all. The ML implementation shows that auto iso with flash works just fine w/o a single problem, I've been using it a lot since years from iso 100 to 6400 with m or ettl, local or remote, optical or radio... either there are historic reasons for the flash lockdown or of course configurations or situations I'm not aware of. The power output level is no reason though.

First of all, let me introduce myself. I am French

Fritz welcomes Frog to the forum :-)

Flash was in E-TTL mode, high speed synchronization,  and the external battery pack was plugged (Speedlite’s C.Fn 12 set to both inner batteries and external battery pack). I’ve been surprised to notice that when shooting 3 photos in bursts, the flash fired the first shoot, but not the following ones.

Hmmm, even with full power it *should* fire more than one if your battery pack is up to it and properly connected (which the flash doesn't show, mind you). You are shooting at worst-case conditions: hss, fill in snow (= fast shutter speeds = full flash burst). To debug, try shooting at a lower flash output with low fps. And don't forget sooner or later the flash overheats and stops flashing bursts.

Another question : why, when using a Speedlite with the body in auto ISO, the ISO automatically sets to 400 ?

Because Canon has a completely braindead auto iso function with flash as you just experienced ... the only way around this is to use Magic Lantern, it has an independent auto iso that works all the time.

Lenses / Re: Canon 24-105 vs canon 24-70 ii
« on: December 09, 2013, 06:59:37 AM »
But, in addition to IQ, I wanted to add that the 24-70 II also has much faster AF, especially in low light, and I believe is focusing in much less light than the 24-105 on my 5DIII.

I'd like to stress the "5d3" part because only 1dx/5d3 are able to make use of the latest lenses (70-300L, 24-70ii) more precise af system, and the 24-70ii is designed in conjunction with the 5d3/1dx af system (lens groups) in mind... there are lensrentals articles on this.

Both means that if buying a 24-70ii for a 6d you're throwing part of your money away and it's a good idea to consider a Tamron as an alternative, I guess that's part of the reason why Canon bundles the 24-105 with the 6d and released a 24-70/4 which doesn't run into the 6d's af problems and at least has IS.

Good advice here.

Thanks, I have been lingering about what 70-xyz to buy for quite a while back then :-o ...

As you are not into shallow DoF

... just one addition that imho is often lost in the debate: at least on full frame f4 @200mm already *is* very shallow and has nice background blur, of course depending on the camera-subject-background relation, that's why I'm also very happy with my 70-300L resulting in f4.5 @200mm. Except for the dedicated portrait style larger apertures tend to fall into the "creative potential, but not always practical to use" department.

it seems to be aps-c only unfortunately
Are you sure? It is listed as Canon EF on the dpreview page, not EF-S.

Google is your friend (ok, it isn't, but it returns good search results): http://www.samyang-lens.co.uk/samyang-10mm-f28-edas-ncs-cs-lens.html

Lenses / Re: Canon 24mm f2.8 IS Prime or Tamron 24-70 f2.8 VC Zoom

I mainly shoot either street photography portraits or studio or location portraits.   With my street photography, speed of autofocus is also key.

You wrote it yourself - if af speed and size (street) is your preference, better be critical about the Tamron... best check it at some shop for yourself, it has a "two phase" af lock that slows things down a bit. A good(!) copy of the Tamron otherwise is a fine lens and the wide end is very wide other than Canons 24-70ii, but for regular f2.8 shooting is has heavy vignetting and lacks sharpness to the edges (if the latter matters at all).

EOS Bodies / Re: "Two New FF Bodies in 2014" - if 5DM4, would you jump in?

As for DXO, while I admit I may be doing something wrong, I have found their software to be the worst of all the available options for editing RAW files. DXO seems to produce the noisiest results, PARTICULARLY for Canon files (they do much better with Nikon files).

I'm *only* talking of the newest nr algorithm labeled "prime" from dxo pro optics 9 ... it's impractical to use for my laptop and doesn't import raw dng, but I compared the trial version enough to know it gives stunning results in comparison to ACR/LR on higher iso settings... I guess Adobe will follow suit esp. if you say dpp is also better (I never really tried the latter either).

they seems to be far slower than Lightroom or DPP, and specifically in Canon's case, the output is just terrible.

Their "prime" is incredibly slow, and the whole dxo software is also way slower than LR for me. Plus I don't like their "settings" style "smart" interface but prefer the plain ACR/LR sliders, maybe out of habit and because I didn't have an in-depth look... but I have to admit you can get very nice "one click" results with dxo's "one shot hdr" settings while with ACR/LR you're quickly getting the feared "hdr look" with high dr images w/o a lot of hassle (tone curves, local adjustment, other external software like enfuse).

I am thinking in the £400 to perhaps £500 budget, so it looks like I may be able to get an F4L IS, F2.8L non IS or I have seen Sigma F2.8 with IS for about the same price.

Don't underestimate the usefulness of IS with these focal ranges, so only get the non-IS if you really intend to shoot mostly at high shutter speeds... for Canon f4 vs Sigma f2.8 refer to the usual review sites, mostly Sigma vs. Canon means better or same iq @ lower price vs faster and more precise af.

What are the chances of getting a poor copy of each individual lens?

Even new there is a small chance, but it's much more likely when buying used - you cannot see humidity damage or decentering from the outside, and the lens has no "usage" counter unlike a camera shutter. The usual advice is to buy lenses only after checking (craiglist and similar) or pose very precise questions to an ebay seller so that you have the option to return the lens if the answers proved wrong. Be sure to check by shooting a a test chart for lack of sharpness and decentering vs. test shots @ the digital picture.

PLEASE don't call me PR!!!

Well, that's what you get for writing something nice :-p ... I'm not up to the correct obvious terms obviously as you relate to the public - otherwise you'd just write a PM to the op - but maybe PR is something different entirely and is considered deprecating since it made you post your qualifications ... so sorry for that.

EOS Bodies / Re: Bought at 6D on Black Friday; AFMA or not?
« on: December 09, 2013, 03:30:43 AM »
4) Selectively use AFMA for my fast lenses (F2.8 and wider)?

This. Unless your f4+ lenses are completely off the scale (doesn't hurt to check though) you'll first want to adjust your fast lenses. Also use search :-) and/or read this thread: http://www.canonrumors.com/forum/index.php/topic,17966.msg333275.html#msg333275

If the answer is to use AFMA, what work flow do you recommend?

I recommend using Magic Lantern, it has an afma module ("dot_tune") that automatically adjusts your lens. If you don't want to use that in the current alpha state, alternatives are the commercial FoCal software or using a simple metering stick, then phase' af'ing on a certain spot and afma'ing until it's where you want it... but you have to do that a couple of times because the 6d af has some variance itsseelf.

EOS Bodies - For Video / Re: 6D can't be this bad can it?
« on: December 09, 2013, 03:24:27 AM »
I'm not sure what competition you're referring to Marsu - the only affordable cameras that do RAW are the Blackmagics, and they're so far removed from a DSLR that they can't be compared. And if you think a BMCC is cheap because the body doesn't cost much you're wrong. Once you add all the extras you're looking at paying more than a C100 for a far less versatile camera (but which does provide higher resolution images with a lot more colour information).

Thanks, since I'm not into video I really didn't calculate the "total cost of ownership", I'll consider this in the future. As for shooting raw, I don't suggest you do it all the time because of the large data rate and slow processing time - but it should prove invaluable to have the potential for select scenes? As for the workflow, things seem to have improved recently because you can directly import the new ML raw format into Premiere CC (if you can afford it, that is...).

Pricewatch Deals / Re: Waiting vs. Buying Now
« on: December 09, 2013, 03:16:29 AM »
I'm in the market for a Canon 6d and possibly a lens or two (70-200 F4L?, though the len can wait)

Imho there is some air left in the 6d's price, it's produced cheaper than the 5d2. However, in comparison to the 70d and considering the fact is the cheapest Canon ff I don't see that much happening to the price anymore as Nikon has released their contenders and nothing is happening in the Canon mid-low ff area until the end of 2014 or 2015... that's why I've bought my 6d at the current price.

Just be sure to use a cashback or similar and don't purchase the lens at full price.

Street & City / Re: Impressions of the weekend, feedback appreciated
« on: December 09, 2013, 03:09:42 AM »
These are really nice, I'd like to give some constructive criticism, but I don't find anything to improve. With the ef-s lens on ff you've found something quite unique, you should expand on that!

Btw it's always interesting to see djs put up a show when basically switching cds and doing some beatmixing :-p
 
The lens I used was a Tokina 12-24mm for APS-C sized sensors.

... and with a 5d2 *snigger* that'll make the "you need a 5d3 to shoot your doorknob in low light" crowd think :-p

The results when using long exposures, zooming and using multiple flashes are pretty interesting, especially in the range where the image circle can't cover the hole sensor of my 5D, it's almost like the light trails are coming out of the picture.

It's a damn pitty the Canon brand flashes don't support 2nd curtain remote sync - is this 1st or 2nd curtain (using your Yn triggers)?

« on: December 09, 2013, 02:43:47 AM »
So, sorry, but the visual evidence says otherwise...there IS an IQ improvement between the 5D II and 5D III, in many ways a significant improvement.

Thanks for doing these gifs, it's interesting and I think I can spot the 5d2's banding - but maybe I'm just looking for it.

Having said that, *significant* in a non-scientific context is very subjective, as far as I remember the context then was the horrendous price jump to $3500 that caught many people off guard and created higher expectations towards the sensor than Canon currently can (you'd probably say: wants to) deliver.

What doesn't show up in the gif and what I have to admit I'm guilty of underestimating: The newer ff sensors react *much* better to postprocessing either in nr or sharpening, multiplying the seemingly moderate step up in noise pattern. Esp. with DxO's prime nr it's stunning how iso 6400 looks on the 6d, if only it wouldn't take my laptop 30 minutes to denoise a single picture :-p...

EOS Bodies - For Stills / Re: The Unthinkable: Swapped out 5D3 for 6D
« on: December 09, 2013, 01:45:45 AM »
Interesting about ML not being able to be uninstalled on the 5D3...
I'm positive this will be solved - actually the uninstallation (i.e. removal of the in-camera boot flag) in 99% likelihood works the same as on every other camera like the 6d, it's just that the 5d3 is the most expensive one and no one wanted to try it yet.
Alex has said that it cannot be done in a 100% safe way. I too truly hope that it will be solved (and that ML would be updated to support the 1.2.3 firmware release).

Thanks for the correction, I admit I didn't read all of the 5d3 thread since I don't own one and was more interested in "payment for features". For everyone else, read further in this 5d3 bootflag thread: http://www.magiclantern.fm/forum/index.php?topic=9274.0
