Lighting / Re: Is this dangerous when using the 600ex rt´s?
« on: October 20, 2014, 08:27:18 PM »
It's no problem leaving HSS as default.

... which makes it so annoying you have to explicitly turn hss on after each battery change, and if you forget it the flash clips at max x-sync and the camera engages safety shift :-\ ... if the flash doesn't remember the setting, I'd rather have a "no hss" setting next to 2nd curtain than the way it is now.

I would like the possibility to stop action with HSS, but also to overpower daylight.

You can use Magic Lantern, dual_iso ~triples+ the flash effectiveness... I use it all the time for high-power hss in bright daylight with a single flash as I find the 6d's max x-sync of 1/180s very limiting.

Lenses / Re: 100-400 with 1.4x teleconverter on crop body
« on: October 20, 2014, 01:22:52 PM »
These were taken with my 7D on the 100-400 with a Kenko 1.4TC.  You must use the outer 2 middle row focus points to get decent focusing ability.  Focus is slower, you need greater light and contrast.

Question is if at this magnification, you'd see a difference with a tc and the bare lens.

To the op: I've just got a 70-300L with the Kenko (you get a working but sloooooow f8 af), so take it for what it's worth - but it's about the same iq or even a bit better than the older 100-400L. Basically, forget about using this on a crop body, you're cutting 1.6x times 1.4x away from the glass and it really shows with these midrange lenses.

I only use it to zoom in on sunsets and the like nowadays that need even more cropping, but for anything that require sharpness it's not worth switching the tc on.

EOS Bodies / Re: EOS 6D Mark II to Move Upmarket? [CR1]
« on: October 19, 2014, 04:03:54 AM »
I think everyone's looking at the 6D as some sort of crippled Mk3.  They're missing the point:  the 6D represents a stripped down approach to full frame.  Its as though Canon looked at the Mk3 and said "What don't we need on this camera?"

... in this case, they could just have added the full-blown firmware - why can I play audio files along side my in-camera slide show, but cannot save hdr source files or do raw hdr? This is software crippling by removal of features, just like removing 1/8000 shutter or 1/200 x-sync is on the hardware side. Beware, it's absolutely terrific you like the 6d just as it is.

4) Focus peaking (not just confirmation)

You do know Magic Lantern has focus peaking and then some, right?

I've used the 6D in the rain and in the cold.  It's plenty robust.  To call this camera "entry-level" is nonsense.

Your opinion of other people's opinions is appreciated. However, one word of warning from bad experience - the 6d's sealing isn't as sturdy as (semi-)pro camera bodies like the 5d3 or 7d, using the 6d in rain w/o any damage basically comes down to even more luck than with other non-1d cameras.

EOS Bodies / Re: Crop camera upgrade
« on: October 18, 2014, 06:11:03 PM »
Are you saying aside from frame rate and AF performance, you don't foresee any IQ improvement for the 7D2 over the 550D?

I'm not in the market for a 7d2, so I only had a rough look. There certainly will be an improvement as your 550d's 18mp sensor is the earliest incarnation, so less banding, a little more sharpness (weaker aa filter), 2 more metapixies, maybe 1-2-2/3 stop iso improvment. Refer to other 7d2 threads or reviews for details - question is if you've experienced the problems with the older sensor the newer one might improve.

It all depends on your budget, but that wouldn't be worth €1700 for *me*, I'd rather stay with my 60d which admittedly has better usability than your Rebel. Camera bodies come and go, the 7d2 will drop in price like all do...

... but for less money (after selling your current lenses) you could upgrade to a 16-35L-IS and Sigma 50mm ART - now *that* would have an impact on your pictures for sure. Having the latest, absolute two top-notch camera bodies and shooting with some medicre lenses imho is a bad decision as your gear isn't balanced.

Thanks to both of you for your comments.  It did seem like it wouldn't provide me any significant advantage over my current equipment.  However, I don't know how much reach I will need to get good shots of the animals that I will see.  Some subjects (i.e. elephants, giraffe, zebra, hippo) will not be moving quickly, so advanced AF is not imperative.

I'm not a safari geek, but I imagine with too far away subjects the atmospheric disturbance in hot climate gets so significant it won't really matter what sensor you're using :-p

After reading those posts, I'm more inclined to use it on the 5D3 and use either the 17-40 or 24-105 on the crop body for wider shots.  It does seem counterintuitive to use a FF for longer shots instead of crop.

Don't only be set upon pixel peeping sharpness, there are other lens propierties. Cropping just the center from a full frame ef lens means a vastly different bokeh and vignetting look wide open. That doesn't matter stopped down, so you should be fine with the 17-40L @f8+ on crop and using your best lens on your best sensor.

I do recall Neuro stating on more than one occasion that the only advantages crop provides are size and cost.

... and other people disagree with our full frame editor, including me and obviously jrista. Crop is certainly great for macro and having to carry around less weight & bulk for the same reach. As you wrote, you're no a pro, so shooting is supposed to be fun - which actually is a good reason to get the 7d2 toy just for the heck of it if you've got the €€€.

Based on that information:  is it worth upgrading the crop body to the 7D2?

Imho you've got all the information you need to make the decision: You know the iq of the 200mm zoom with tc on crop (won't change with the 7d2), you know the af performance of the 5d3. Looking at the shots, the 7d2's sensor performance isn't revolutionary.

Now - is having an equal af system on the crop (but with af points nearly all over the vf) and more fps worth spending €1700 on? If in doubt, what other gear parts would you spend that amount of money on as an alternative? Some of your lenses are medocre, there are good replacements esp. for the 17-40 and 50/1.4.

You can use a 3rd party program to modify partitions: Mini Tool Partition Wizard

Sure, but modifying (esp. system) partitions is still open heart surgery, no matter how stable these tools are. This means a lengthy backup, not just the files, but the whole thing and creating and testing os rescue procedures as I don't want to have a bricked system. Given the choice, I'd rather just move a folder, thank you very much :-p

Those folders are managed as "special" ones by the OS. Their position can be changed, but it needs to be done properly (it implies registry changes and so on).

Not necessarily, with the ntfs file system there's a fool-proof dumb method to move folders anywhere else (like another partition) w/o the operating system noticing: http://technet.microsoft.com/en-us/sysinternals/bb896768.aspx

For example to move all Adobe Programs from C:\ to somewhere else first move the folder with explorer, than from an admin command prompt: junction "C:\Program Files\Adobe" "X:\Where\You\Moved\It\Adobe"

I'm using this method to free my system partition since I chose a too small size on installation and don't want to go trough the hassle and risk of re-partitioning on the fly.

EOS Bodies - For Video / Re: IS on when filming on tripod?
« on: October 18, 2014, 12:32:33 PM »
For the 100mmL, it doesn't matter, it shuts down automatically.

Indeed it should, but in my experience even small tripod shakes can fool the tripod autodetect and turn IS on again - so I always turn it off manually. My impression from longer time exposures also is that turning IS off helps, but I cannot provide real proof for that.

You don't even need to use the physical switch for that, just assign a camera button with "IS Start", for example in in a dedicated "tripod" c mode (I found out that this is a quick way to disable IS after a panic attack thinking my IS was broken :-p).

Yes, the updates will take a lot of time, but that's a good thing, not a bad thing. You'll be much happier not doing it off a wifi network, and if you've ponied up for decent bandwidth from your isp.

Btw if you're not using a slipstreamed iso file, there is the possibility of pre-downloading all the updates and then running them off the disk/dvd/usb dongle and not off the net - very useful for multiple installtions. The further advantage is that the usual suspects like vc runtimes and directx updates get installed right away, too:

There are a couple of programs that achive that, here's the one I use (yes, it's also in english): http://www.heise.de/download/wsus-offline-update-ct.html

I'd doubt the subscription service rumors.  Do you really think Dell or HP would go for that?  I wouldn't either.

"Last Windows ever" (if they really said that and meant it) would not only relate to the payment method, but to the upgrade policy. Microsoft has went away from releasing big service packs more and more, and with windows 8.1 they started experimenting with a rolling release scheme with frequent feature updates.

And what's so different between a long-term subscription payment (maybe 3 years with your new pc) and buying a Windows version that is phased out in the same timeframe? Answer: No difference, it's just an increase in the version number that doesn't say anything about the content.

"End of subscription" doesn't necessarily mean the product self-destructs or becomes unusable like with Adobe CC, with a lot of other software products it just means the end of updates and support - you can continue using it anyway.

EOS Bodies - For Stills / Re: LP-E6N Backwards Compatible
« on: October 17, 2014, 05:46:07 PM »
I asked the same question at Photokina fair in Germany last month and was told it is backwards compatible. Anyway, advertised higher capacity is negligible in my opinion (1850 vs 1800 mAh) and not worth the money.

An in-depth test might reveal that there are other benefits, maybe more recharge cycles or faster recharging?

Knowing Canon, there might be another agenda: the new battery type might have a much more elaborate counterfeiting prevention, and with newer cameras or 7d2+ fw upgrades the old lp-e6 might be disabled by Canon.

They showed how important battery sales are to them with the latest 6d/5d3 fw upgrades that adds warning messages and chargers that don't accept detected 3rd party batteries anymore.

You can see my photographs here: https://www.flickr.com/photos/michaelhooper/

Seeing that you're doing a lot of "animal in motion" shots, the 7d2 would certainly be a huge improvement. But I applaud you for even trying with the 600d's system, with my 60d (same af system) I know how limiting it is.

I can't select the iso as exactly as I'd like. With the 400 5.6 I often want to shoot between 400 and 800 and I can't.

Just don't - intermediate iso stops are just digitally over- or underexposed versions of the base iso. It can be argued that due to Canon's specific low iso read noise problem, some 160x iso stops are a very tiny bit better, but really nothing to write home about or upgrade for. My advice: simply shoot raw with full stops and worry about the image content.

At 800 iso I have very little dynamic range to play with, so if the bird is black and white I'm in trouble if the exposure isn't perfect.

A 7d2 won't fix your b/w problem at this iso range, nor will any other crop camera of any other brand. The only available option with current tech really is to get a full frame, then you can try to squeeze the last bits out of the shadows w/o running into shadow noise or banding. It's a worst case scenario just like wedding dresses, but with animals you cannot use controlled lighting like with people.

I only shoot in manual, and having a bit more customizability might be good. Certainly having a couple of definable presets would be very useful.

Use Magic Lantern - available for your 600d, but not for the 7d2 (and no, it'll be not ready shortly after release, if ever).

I sometimes wonder if something in the middle would be useful! 100 2.8L?

I don't really know about your specific requirements, but the 100L is always a safe bet - great iq and the most fun lens since there's no minimal focal distance. The af is a bit slower though, it's a macro lens after all.

How well does the Canon's AF assist work? :)
Point taken, but as it turned out Yn's af assist performance in real world use is 100% up on par with the Canon :-p
The 600-EX-RT AF assist works very very well, obviously the joke was on the ST-E3-RT AF assist being non existent, but we are onto the YN-600-RT now, and I am sure the assist on that will not be anywhere near as good as the Canon version.

Ok, this probably was too sarcastic to understand: Imho Yn's af's assist beam's performance is up on par with the Canon controller because Yn's is useless, and Canon's is non-existent :-p

I noticed that they require fresh batteries, and whenever I have a misfire - I change the batteries and we are good to go again.

Thanks for reminding me, I almost forgot that "fresh" batteries really do help... I just didn't remember because my Canon 600ex unit as a master works 100% until the very end. There seem to be very different electronic parts inside Yn vs. Canon.
