Lenses / Re: Help: 24-105L making faint noises

The IS starts only when you half press the shutter button and stops about 2 seconds after you release it.  That is almost certainly what you are hearing.

Software & Accessories / Re: Focal vs Focus Tune
« on: April 10, 2013, 09:52:43 PM »
I doubt if there is any difference in results.  FoCal has had time to make several improvements over the past 1+ years, and they now understand the limitations of AF systems much better than they did.  They do still discover new things almost every week.  There is a new post about discovering a bug in Nikon Firmware for almost every Nikon Camera that causes it to put the wrong AFMA value in the image metada, which, of course affects the testing.
 
Autofocus varies from shot to shot a lot more than we think.  Usually it is not enough to notice unless you are really looking hard, but it also flat out misses.
 
FoCal has so much data from the thousands of tests that they can predict the correct AFMA with only two shots, the third shot being used to verify the results.  They have developed a much more accurate AF algorithm than the one Canon uses in liveview, so they can determine the peak resolution of a perfectly focused lens, and then use curve fitting with two points.
 
The FoCal manual is available for viewing or downloading.  I sat down and read all 130 some pages a few evenings ago.  I learned a lot about how Canon and Nikon's AF works, and at least some of the weak points.  Its worth reading about the tests you can run even if you don't buy it.

Pricewatch Deals / Re: Canon Refurb 400mm f/5.6L $910
« on: April 10, 2013, 09:31:16 PM »
Its a good lens for BIF, fast AF and reasonably sharp.  I had one and sold it in favor of the 100-400mmL.  The issue I had was its length, its a great lens for the price.  It is fairly long, and does not fit in a lot of camera bags, while the 100-400mmL is actually shorter when collapsed than a 70-200mmL MK II.  A 70-200 with 2X TC is cumbersome to hold, but can produce excellent images.

Do you still have the 100-400mmL and/or the 70-200 with 2X TC?

Yes, I have both.  I much prefer to use the 100-400L at 400mm.

Haven't heard of this "EQD" brand.  Would it be just as good as a Dell IPS 24", which often is on sale as well?

Where are you seeing EQD? I'm seeing Monoprice-branded displays. I assume they use LG panels.

He is referring to the post about a 24 inch panel.  Nothing to do with the original topic on a 30 inch monitor.

Just added to the refurb site.  I don't recall seeing it here before.

Yep I'm using the new version already.

Crazy.  Every time I tried it the program would crash and I would have to manually restore my settings.  Maybe I'll uninstall it, reboot, and re-install again.

But it doesnt work with the 5DIII (reikan af algorythm).


Works just fine with my 5D MK III!

Be sure to use the new version, they fixed those crashes now.
I should elaborate, I have it installed on two computers, and find the function crashes frequently on one I seldom use, but works fine on my laptop which is what I normally use.  Both are windows 7 64 bit OS with 4GB memory.  I've never bothered to find out why.  The one it crashes on is a older Dell, but upgraded with a SSD.

I've had a 40D that has literally gone unused since I bought it shortly after the 40D was made available. 

I can already hear all the WHY's?

Well, I've been shooting film up until January of this year.  I had several film cameras including a 4 x 5 so the 40D wasn't being used.  I've been slowly selling off my film camera gear.  Before coming across this post, I was considering selling the 40D. 

Maybe I should hold onto it.   :)

I bought mine from a seller who wanted video.  The price will keep dropping, so, if you don't use it, sell it.  You can always buy one later for less.
I likely got a deal, $300-$350 is the top price.

EOS Bodies - For Video / Re: New 5D3 Firmware Spotted!!!!!!!
« on: April 10, 2013, 01:34:47 PM »
Atomos page says Canon won't ship the firmware until May.
http://www.atomos.com/whats-new/


People claim to be already seeing it in new 5D MK III's.

Careful testing at DXO shows that with the same lens, the 5D MK III has 15% better resolution than the 5D MK II.  Thats quite a bit for a tiny number of additional pixels.
 
Its hard to know why you are seeing this, but somewhere along the line, something is wrong.
As Neuro said, live autofocus is done by contrast detection and should be near perfect.  Reikan Focal has a focus algorithm that will focus your camera better than liveview, and can be used to check images as well.

EOS Bodies - For Stills / Re: Charge new LP-E6 batter over night?
« on: April 10, 2013, 01:25:18 PM »


I'm curious if Canon makes the camera shut off at a certain voltage, above the trigger point for the protection circuit in the LiIon.  Seems like it would be easy and allow you to run the battery until the camera shuts off.

Its built into the Li-on battery, its in all of them.  The electronics shuts off power to the camera with a safety margin.  Without that, li-on batteries would die the first time they were fully discharged.  Its a good idea to store them partially charged.

I'm still a faithful 40D user.  Well, I should say my assistant is, as it serves as a backup body for me and he shoots with it when I don't have it on me.  I'll put an L lens or a 50 1.4 on it and it still pumps out beautiful images.

I took a few test shots last night indoors at up to ISO 3200.  It handled the exposure nicely, and with modern raw processing, the high iso image turned out much better than expected.

We continually get suprised by things like this, and learn.  It is possible that the lens developed a issue, or that you have a filter on it.  Filters generally don't like that kind of lighting, but different ones handle it differently.

Thanks for the replies. Would it be risky to use my other Canon battery in it as the original 6D battery charges? I want to use it right away  8)
You can use the old battery safely, but there have been a lot of compatability issues noted while trying to charge the old battery in a new charger.  If that does not work, ask Canon to replace your old batteries.
