I tried it out in my studio, but its in a trailer, and the vibration and movement of the floor makes it difficult to actually test the lens / body, even with a ev 12 lighting.  Once weather improves, I'll run it outside on concrete where I have brighter light and no movement. 
 
One of the things about focal is that the camera needs to be very stable to get the best and most accurate results.  I think its trying to tell me that I move too much.

Technical Support / Re: Is this dust or sensor damage?!
« on: April 11, 2013, 12:58:39 PM »
Do a little more testing to narrow it down. Its hard to fix a issue until you understand just what it is.
Take a 5 second exposure with the lens cap on.  (Use AI Servo)  This will let you see if any pixels are stuck "ON", but seeing the ones that are off is more difficult.
 
Set the aperture to f/22, but the lens in manual focus and set it to mfd, and take a shot of a evenly lit portion of the sky or white wall.  Dirt and dust blobs of verying sensities will show up. A block of pixels that are stuck off are obvious.   Usually, most dust will merely blow away with use of a rocket blower while the camera is in the manual clean mode.  If that doesn't work, Canon will clean it for you, but it might not be covered under warranty, so ask.  They are not always consistent about this, if you just received it dirty its one thing, but owning it longer might be treated differently.

It can't be too high, this thread is still here :)

Now that's offencive, Sir.

For what it's worth, I can comprehend the Queen's English perfectly.  It's the local patois that I have trouble with...fortunately, I found help.

Just humor, but I apologize for any implications that it applied personally to you or any other poster.  If it did, I'd be implicating myself. (not a unreasonable thought  ;) )

Lenses / Re: $1000 budget, need lens recommendation for Canon t1i
« on: April 11, 2013, 12:44:35 PM »
I'd say get two flashes with remote releases like pocket wizard or chinese knockoff, flash / light stands, large umbrella reflectors, a tripod, remote release, and you are fine.  The 18-55 is plenty sharp, but you need evenly distributed light, and lots of it.

EOS Bodies - For Stills / Re: 5D 3 sales
« on: April 11, 2013, 12:37:20 PM »
Spring is the big sales time for cameras.  People buy them for upcoming weddings, vacations, graduations and more.  So improved sales are not suprising.
 
With the EU economy fears, it is suprising that sales are booming, but maybe people have more willingness to spend than the news types think.  I have a investment in a EU stock mutual fund, maybe it will take off ;)

EOS Bodies / Re: Is the SL1 sensor an improvement?
« on: April 11, 2013, 12:31:40 PM »
Its at least two generations newer than your T2i.  Some seem to think that the number of pixels defines a sensor generation.  It doesn't.  This is supposedly a second generation Hybrid sensor.
 
As far as IQ, at low ISO's you are almost certainly not going to notice any difference.  Improvements to sensors are most noticible by the reduced noise at high ISP's, or, in this case, by better hybrid autofocus.
 
The bottom line is that its a improvement for focusing in the live mode, and probably has a bit lower noise at high ISO'sin jpeg mode due to the new Digic 5.  Certainly no big difference unless you want autofocus while taking video.

Lenses / Re: Help: 24-105L making faint noises
« on: April 10, 2013, 10:03:54 PM »
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.
