As I stated, the majority of situations which people call "low light" really offer plenty of light for the AF systems of even low-end dSLRs.  The extra one stop of sensitivity that the 6D has is an advantage only in very rare situations, so rare that many 6D users probably have not ever experienced them.

Having shot with the 6d and my 70-300L I changed my opinion and would disagree here:

The 6d still af's in dim light @f5.6 aperture just fine w/o af assist, and the exposure was taken care of with some flashes and iso 6400. For the big boys with constant f2.8 zooms pr even faster primes that might not matter that much, but for the cheap rest of us 1 more stop of af capability can come in handy

Try testing it at the highest shutter speed, that's when issues usually start surfacing.

Thanks all, I'll try to replicate it so service has to take the problem seriously...

... otherwise looking at the other answers I'll wait some more as the 1y warranty end is some months away. Afaik in the EU, during the first year the manufacturer has to prove the item is ok, after that until 2y it's vice versa which might make a difference concerning the willingness to really search for the problem.

Technical Support / Err 30 (stuck shutter) once - get it serviced?
« on: April 08, 2014, 03:21:20 AM »
Today when shooting quick series of shots I had a err 30 on my 6d (with hss flash, if that matters). It went away after a power cycle.

I researched the net and at this stage it doesn't sound too serious, but do you think I  try to get it services anyway as it's under warranty with cps? Or will they tell me "Well, we did a few test shots and everything's peachy"?

Here is what I shoot: Landscape, wildlife, light trails, sunrises and sunsets

If you think of wildlife as "tracking moving animals" then forget the 6d, the servo capability is abysmal (basically center point only, outer points are useless as is multi-point af mode). For everything else it depends on what image quality you want to get, it doesn't sound like you need the thin depth of field of full frame and 70d is certainly "good enough" for everything you at an ok price... though it doesn't run Magic Lantern.

Not only 4k with global shutter, but they obviously had a good look at 5d3 Magic Lantern: 12ev dynamic range with 12bit raw recording (should keep data rate a bit down vs. 14bit ML). And it has a swivel screen :->

Didn't you get the cables included for the remote and linked shooting?

Yes, sure, the cables are there, with "though it needs a shutter release cable" I meant to say it's not as easy as on my 6d as the 60d needs the cable attached.

Probably the projection grid in your YN-E3-RT is misaligned.  Can you return/exchange it?

I don't think there is an alignment spec at Yongnuo, it goes where it fits, if it doesn't fit push it harder seems to be the QC ethic.

Doh, I can get it exchanged or even returned and I still would like the Yn because of the af assist if it works.

Edit: I've found the cause, it's an issue on all Yn units, read more about it in the neighboring thread: http://www.canonrumors.com/forum/index.php?topic=18534.msg385243#msg385243

First to the op: Another reason for the st-e3 beyond light/small is that it's cheaper, meaning less things can break and need servicing (think "dropping your camera").

Some European countries allow it, some don't. But you are OK, Norway is a yes.

That's because these rich oil diggers aren't part of the EU :-p ... for the European Union, you have to pay taxes and customs. For Germany it's <22€ free, <150€ vat only, >150€ vat+customs.

There is Yongnuo version of ST-e3 with AF assist but you can use it with a central AF point only

Ugh? I just got the YN-E3-RT and you nearly never can use it with the central AF point as it projects the red stripes right next to the point. Multipoint af works better, but alas, is also useless with the 6d's mediocre outer af points. I'm really puzzled, am I doing something wrong here?

Well that's disappointing. I'll need to figure a quick means to disable.

Don't let me detain you from also posting this issue in the ML forum and on their bug tracker, if there's enough request the devs might have (another) look at it and probably find a way around it, you never know:

If I needed the AF assist and it was a critical work environment, wedding receptions etc, I'd suck it up and get a 600 for on camera, besides, it is rare that an on camera fill or bounce is useless in those situations.

Jee-jay! After only two months of waiting for this thing from China, I finally have the item of my dreams in my hand. Lesson learnt #1: Don't buy from shady e-Bay sellers to save €5. Speaking of cheap, here's my impression.

Let's start with the positive facts:
+ Yn is cheap
+ Yn rembers the HSS setting even after switching through modes, Canon forgets it once you cycle though ext-a and you have to set it again.
+ Yn works with my pre-2012 60d and supports linked shot, though it needs a shutter release cable.

This leaves a mixed feeling:
+- Yn supports 2nd curtain remote. But, alas, not only does it work in M mode as written in the specs but it doesn't work in M group mode but only in the good ol' a:b:c ratio system.
+- Yn doesn't support 1/2 ev stops and interprets -1/2 ev fec as 1/1 (not -1/3 as it would make sense). For the 6d, this happens to be a blessing in disguise as you can use max. x-sync of 1/180s and still set 1/3 stops on flash.

Next up are the downers:
- Yn's wheel is really way too easy to move, when in a hurry you're not able to set it precisely.
- Yn has no personal functions if that matters to you.
- Yn's power saving setting is only off or the very short 5min, not 10/60 min like Canon

Last not least, here's the complete bummer:
- Yn has af assist, the very reason I bought it. Unfortunately this is completely useless as it uses a fixed pattern that projects the red stripes in almost all cases next to the center af point.

EDIT: This is not just my unit, it's a systematic failure on the Yn! The pattern is too wide so you need to move either the trigger in the hotshoe or walk back and forth which makes it "nice to have" for pitch black indoor shooting of static scenes, but utterly useless for anything that moves. Doh, it I wouldn't need this to make my 60D work with the rt flashes I'd return it :-\


The only issue i can find that is still really annoying is a slight delay to wake the camera up from sleep.

This cannot be changed as ML is in fact (mis)using Canon's own firmware development hook to load an additional fw from card, and the Canon lab boys don't seem to be that concerned about startup time when working from their desks :-p

Lenses / Re: Canon lens registration

For lenses, require proof of purchase AND warranty card?

At least in the EU, you can forget about any warranty cards, the receipt is the only proof of purchase required... you also don't need any original packaging as some manufacturers try to tell you.

If you want to expect a range of aspect ratios with one button click, I would never do that.  One of the most important parts of my work flow is cropping for composition and usually crops are not centred on the image.

Exactly, that's why I want different non-centered custom crops in *one* image w/o maintaining and syncing virtual copies just for this purpose.

What about exporting from Lightroom and cropping to multiple files in another app?  I don't know which one but it might be easier

I though about that, but I'd need a way to get the crop information (what parts to cut) out of LR. It could be done with keywords describing what pixels to cut, but I'd lose the cropping gui in LR.

Alas, thanks for your answers, as I expected currently there's no way around virtual copies :-\ and I now faintly remember already having read about others with the same problem. I hope Adobe sometime adds a way to have multiple crops in one image...

I know this isn't exactly a LR forum, but in the abscence of a 7d2 or 35L rumor for over a week :-p probably someone can help:

My workflow contains exporting to different aspect ratios for screen and print (2:3, nearly 2:3 paper size, 16:9, 16:10, sometimes 4:3). Problem is that with Lightroom, I currently have to add another virtual copy, crop it and sync all changes from the master (there is a commercial plugin for this) to the copies. All in all, quite a pita.

Is there some smarter version to have different crops in a single LR shot and export all these cuts in one go, most likely via a plugin I'm not aware of? Am I the only one with this annoyance, do you only export 2:3 and everything's peachy?

Is the wide panel pulled out?
Yes, it is.

Btw the wide panel tends to get dirty sometimes so the flash doesn't realize it's retracted, in this case you have to clean it and try again...
