I've never tried a 6D but a few weeks ago I saw some photos posted in the sports section and said if anyone questioned the 6D's capabilities I'd refer to them to that thread...

It's not about getting *some* shots right, it's about reliability and the keeper rate. The 6d's tracking is medicore, though as written above it depends on the movement type and it's easier with large targets in bright light so you can use all af points (as there's only the choice between 1 and 11).

I've got top-notch running horses shots from the 6d, and I could say they're taken with a 5d3 or 1dx and everyone would believe it. That's why posting some nice sports shots doesn't mean anything unless he/she states how many shots were missed. For some sports, this should be ok as the scenes get repeated so if the 6d misses you can just try again. But for mission-critical work like tracking a "once in a lifetime" wedding ceremony - no, I'd rather use one shot mode thank you very much :-o

The only major thing I've noticed about the 9.5 release is that PRIME has gotten a little slower.  I don't know if they've been able to pull out a bit more quality, but it does seem slower than it was when they first released it.  I'm happy to wait for it given the results, of course.

Let me/us know if you discover anything or read about changes in the PRIME output. Or is there already some tutorial available when PRIME makes sense?

I tried it with a DxO trial version back then and discovered that it takes 15min to process a 20mp file on my laptop so I didn't have the time to experiment with it. In hindsight, the output didn't seem to be always that superior to Lightroom/ACR *if* not going for 100% output resolution, but downsizing and sharpening a bit. PRIME is certainly overkill for your average iso3200 shot. It might be better for extremely noisy shots like iso 12800 underexposed - it's just that I don't do these anyway.

For some of my shots, PRIME turned out to be rather mushy, my preference in these cases would be to keep a little "nice" 6D noise in LR as it looks better to me. Probably the same reason mpeg4 asp videos sometimes look better than mpeg4 avc with stronger deblocking.

Is Wi-Fi on the 6D as bad as on the G1X??

Once you manage to get around the braindead Canon limitation (you must install a virtual wifi access point on your pc to connect the camera) it's quite ok.

The limitation is that obviously without a real antenna the connection strength is limited when a wall or a long distance is involved, and even @100% speed I'd rather put the sd card into my laptop than to wait for the wifi transfer.

However " gift horse and such" ... and I recon it's invaluable once you use it for certain wildlife setups or quick blog uploads for journalism. For longer runtime, an external power source or grip is advisable though to extend the battery time.

As for A-GPS, it does significantly speed acquisition by prefetching the almanac and ephemeris data, but there's no good way to do that with a camera, because cameras don't have cell hardware and aren't typically tethered to anything with an Internet connection.

Afaik there are two "agps", one mobile camera type which uses the cell information and one offline type which simply pre-computes the satellite paths so the tracker doesn't need to search for all of them. For the latter you
could simply upload the data via usb/wifi or put some agps file on the card, afaik some trackers do this

However the 6d gets a fix rather quickly, so I don't think there is a real need esp. since gps doesn't need much power so you can simply leave it on. Magic Lantern has an option to turn it off automatically on camera of an then on again which saves battery btw, and a "hot start" gets a fix even quicker.

Not really, they have had FilmPack plugins for LR and CS for years.

Ok, thanks for the information, I was thinking of their refusal to import raw dng files (Adobe standard) and the position they take in their forums on this issue - Adobe? What's that? :-p

Does Lightroom have face detection?  I find that to be a handy feature, a few clicks and I can build a slideshow/movie of one of my kids, for example...

I'm positive Adobe will keep adding features with their upcoming releases, for example focus peaking (Capture One has it) - LR6 is about to be released, and they won't stop there. I do hope Apple replacement app will be competitive though, any manufacturer having a monopoly is never good from the users' perspective.

I don't know that they've ever tried.

Well, at least they tried to ignore that there is a thing such as Adobe or Lightroom, and this has changed now.

Personally, I use Aperture for that (for now...).

Aperture? The program recently abandoned by its manufacturer? Well, we might have you join the LR users group at last then :->

Has anyone seen this body before? It is a 6D, stripped of wifi and GPS. Price is 30% less than a regular 6D. On offer in Norway today.

30% lower than the lowest mail-order discount price you can get? Well that's tempting, but ...

* I have to admit the gps function is very handy since it doesn't drain much battery and you don't need to merge a separate tracklog in postprocssing. Not really necessary though if you already have a dedicated gps tracker that is bound to be more precise than the 6d.

* Canon's wifi implementation is somewhat lacking, but if you manage to set up a virtual access point on your pc controlling the camera wireless with your laptop can be nice for wildlife shots. Using it with a mobile phone (ios/android) for odd shots or selfies is also handy. Last not least, if you're a journalist you can offload shots quickly to your employer or your blog.

Without such download, acquisition takes a fair bit longer. Would such method exist for the 6D as well?

Nope, Canon's gps is very basic and the worst part is that it doesn't record where the camera is pointing (unlike hotshoe gps receivers) so it's really no advantage over a dedicated tracker, but just a convenience.

Fyi: DxO Pro Optics 9.5 has been released with supposedly tighter integration with Lightroom.

In practice, this just means that DxO accepts that cannot compete against LR's library management and have to integrate with it, but this could be done before. Let me know if there's really anything wortwhile new here.

The big joke is that even with the official LR integration, DxO still cannot read dng raw files but is happy to export linear dng. In practice, this means that the workflow offer is still a big fail for a lot of people who have converted their raw files to dng for one reason or another (there are a couple of good reasons).

People who own the 6D and use it (including me) seem to be generally pretty pleased with it's performance and likely (I don't want to speak for everyone, of course)

Indeed, count me out of this summary. The 6d's tracking is mediocre at best, might work ok-ish with the correct c.fn settings for spatial movement but is a complete failure for towards/away esp. if being forced to track with a single non-cross point... up 50% keepers for running horses if I'm lucky and I really tried about everything.

I find the 6D to have better focus than any crop camera (and I've owned them all).

I'd also tend to disagree here. I've never owned a 7d which has said to have ok tracking capabilty, but my 60d is at least as good as my 6d and you don't have to worry about "oh no, it a non-cross point" but just can use them. The low-light capability of the 60d is very handy, mind you.

If it's just actuations, that doesn't worry me at all.

Not with a 1d, but if you have a 100k-rated camera (60d, 6d) and your doing focus stacks all the time you start to think about if it's really necessary to do quick af... besides, it really hurts to hear the mirror flip on each af, a real reason to get a 70d with an actually working lv af system.

Why would the camera close and reopen the shutter when doing a live few quick focus?  I would think it would be sufficient to just flip the mirror twice.

I don't know, maybe protect the sensor from dust being whirled around when flipping the mirror? But each "quick af" operation certainly counts as a shutter actuation towards certain doom(tm), even though at least Magic Lantern has different stats for lv actuations and non-lv shots.

Why do people keep thinking that a 24-70mm f/2 is even remotely likely?

Hope dies last and if there is nothing really looking forwards to (clean iso 12800, f2 zooms, ...) you won't be able to satisfy your gear acquisition syndrome in the future, meaning severe withdrawal symptoms in the future.

Yet oddly there are millions of people taking pictures they are perfectly happy with using Rebels every day.  I know I did.

I admit I really do find this odd esp. if you've used at least a xxd camera type before - the Rebels are so crippled in the fw (well, Magic Lantern somewhat compensates) and body usability (small grip, no back wheel, no nothing) that I wouldn't want to use this handheld all day long. Probably doesn't matter on a tripod for landscape though.

Personally, when focus stacking, I never change the frame i.e. camera never moves

I also do this with Magic Lantern, the catch is that when re-focusing the image magnification changes which means that you are missing image data behind objects.  The software tries to compensate by adding some reconstruction blur, but this often doesn't work esp. not for high-iq pro purposes.

There are only two ways around this problem: a) use a macro rail which forces all images to have the same magnification at all focus settings or b) stop shooting at the first large object and remove clutter in the foreground.

Crop is 'all about' getting 95% of the product for 50% of the price.

Well, I guess that was in the bad ol' times. Unless you're completely broke getting a 6d or used 5d2 gets you into into ff territory at a budget recently unheard of. Heck, even *I* have got a ff, and that's sayin' something. For 50% of a 6d you're getting a Rebel, and I somehow doubt you'll want to produce anything with that kind of usability.
