EOS Bodies - For Stills / Re: What is 20,000 shutter clicks worth?
« on: August 12, 2013, 11:24:20 PM »
I guess if you wanted to put a dollar figure on it the extra is about 6% of the rated count. Not sure exactly what a replacement shutter costs but if say $500 then it would be 'worth' $30.

Canon General / Re: What am I doing wrong???

if you let the camera choose the focus point, it will choose use the one with the closest subject. on a face it will focus the nose not the eye.

i shoot portraits with one point focus and ai servo, if i dont have to recompose. maybe it helps to only let the camera choose cross-type points.
+1, looking at those images given the position of the focus points I'd say that's the case. 5D3 allows the focus point to be easily be moved with the joystick so the total auto-selection modes are an abomination in my opinion.

Someone asked me about this for at engagement party and I just said my gear was set to take high-quality RAW photos that weren't compatible with projectors ;). Reality is it would have just been a distraction for me and without vetting to some degree you're likely to put up a few OOF / wrongly exposed / timed images up on display. Don't know about you but I also normally fire off two or three shots to cover closed eyes and wierd expressions so I would have also been streaming a lot of virtually identical images.

Technical Support / Re: at what shutter speed you turn IS off?

Another reason to switch it off aside from the potential effect on AF speed/accuracy is that some wildlife reacts to the sound of it.

 ???  Wow!  Really??  So does this mean that if you turn off the IS, you only get one shot when the much louder SLR Actuation scares off the wildlife?

Actually that wouldn't suprise me for a lot of animals, for example from Wikipedia "Bats that can detect 200 kHz cannot hear very well below 10 kHz". Mice are shown at 1 to 70 kHz and there are many other examples at http://en.wikipedia.org/wiki/Hearing_range. According to the following page the USM motor runs at about 30kHz:


Note sure what the frequency components of the shutter noise are, but I'm pretty sure the loudest components would all be below 1KHz.

Technical Support / Re: Very soft audio w external mike of EOD 5D3
« on: January 21, 2013, 06:21:11 AM »
I'm far from an audio expert, but wouldn't the DR-100 if it's pro product possibly inject DC power over the XLR connector? Mt Spokane could well be correct on the battery, I've had few new duds, plus possibly the mic is faulty and only works when line powered. Could also be a signficant impedance / level mismatch, but don't really no enough about the charatersitics of either to know if that's likely.

it works for canon because a huge percentage of fanboys are stupid.
I used to be a Canon fanboy, the mirror actuation kept me somewhat cool, but I've since found a combination of vanes and a DC motor is both more effective and economical.

Looks too well done.
Just a quick sear on the BBQ, was still nice and rare on the inside.

Here's a kangaroo shot I took 5 years ago or so, delicious :)

HDR - High Dynamic Range / Re: Best HDR Software?
« on: January 12, 2013, 02:49:44 AM »
I've never actually used it for HDR (it does other stuff as well) but PhotoAcute has a demo (watermarked) version if anyone's interested in trying it:


The pro version (which you need for a DSLR) is $149 although by submitting a new camera / lens profile you can get a free license. I did the 7D + 70-200mm f/2.8L II profile a while back although my results were a bit mixed with the super-resolution it'd be interesting to hear from anyone so inclined how it does on HDR.

Has anyone upgraded directly from the 7D to the 5D2? How does it do in terms of low-light performance? Is it worth the jump?
I've made that upgrade and low-light ISO and IQ in general is much better. It sounds like you desire the wider field of view you'll get, so the main other thing you may miss is a good spread of AF points. Controls are somewhat different to the 7D (which is better in that regard) but not really enough to be a major concern. Personally I did later sell both and get a 5D3, but only because I also shoot a bit of action type stuff, for portrait style photography I think the 5D2 is much better than the 7D especially in low light.

As Hobby Shooter said I wouldn't dismiss the 6D without trying it. I haven't myself but assume being a later camera the menus and controls are closer to a 7D. I don't know what real-world performance / noise is like but the 6D goes to higher ISO as well. Not sure how it compares to a 5D3 but my 5D3 is noticably better at high ISO than a 5D2.

Honestly, I don't expect the ML team to break this. It would take too much work to benefit a small few. Plus they know the implications of possibly pissing off Canon. It's not impossible for Canon to lock out ML on ALL cameras, would you honestly want that to happen?

Seriously, some people just have no respect for IP.
Agree with you on the first point and being a non-profit group of volunteers even though legally I can't think of any leg Canon would have to stand on of course any lawsuit even without merit can cost stacks to defend.

But "no respect for IP" makes no sense at all to me. Even the DMCA which is pretty draconian in my opinion allows reverse engineering for the purpose of making one piece of software interoperate with another under section 1201(f). Under Australian law that 'no reverse engineering' stuff would probably be a borderline case of unconscionable conduct under consumer laws, of course once again if you had the money to defend it so I understand the stance of the ML team. But it doesn't exactly make Canon's stance either lawful or just.

Lenses / Re: EF 200-400 f/4L IS 1.4x Production to Begin in Q2

Isn't that extremely expensive? I mean you could get the 500 or 600 IS II for less than/around that.
I was thinking the same, it'll be interesting to see how it goes. It's also at a point where you could get both ends of the focal range at f/2.8 with a prime for less.

Third Party Manufacturers / Re: Sigma Launches the Sigma USB DOCK
« on: January 10, 2013, 07:27:43 AM »
Final comment: I don't get some of the thinking on this thread at all. This is a puck to reprogram lenses - how often are you going to do that? How many people are actually going to buy one? Is going into OSX or Windows that much of a pain for that twice a lifetime event? Seriously?
What they should do is have the option of a toggle switch on the data line and a debounced pushbutton on the clock line to make it OS agnostic.

I always use live-view myself and the self-timer if not using a release. The thread just reminded me I saw the following vid on YouTube of a 5D shutter in operation filmed at 2000fps I thought was fairly interesting:

I see they've added that ability for the 5D3 and later :).

Canon is a very conservative company - the lens fw update mainly seems to be designed to ensure compatibility of lenses with newer camera bodies, on each new generation release there are a few lenses (even newer ones) that need a trip to Canon service because they have issues. But Canon isn't enthusiastic about (too?) many customizations or features, they leave that to Sigma and Magic Lantern.
Yep fair point, and I guess in Canon's case they already know likely incompatibilities in advance unlike 3rd parties that need to react / reverse-engineer changes later if previously unused commands are used.
