EOS Bodies / Re: 1dX dust in viewfinder
« on: August 18, 2012, 11:54:08 AM »
Usually, a rocket blower will clean off the dust, on my 5D MK III, it did turn out to be on the mirror, and cleaning it solved the issue.
You can ask Canon to clean it as well.

OH HO!!!!!!!!
Update on my lens... that clicking noise is now gone!!!!
I left it on the bed for awhile after I got upset.
And now... its silent the way it is supposed to be!!

I hope it was just lube or something that hadn't set in or something that was pushing or idk....

Thanks for the help!
I'm glad its gone, but its pretty suspicious, a intermittent issue can be nasty to isolate, even for a repair depot.  It might have some damage from return shipping to you.
Take it out and give it a good 1000 photo workout while you can still have Canon repair send you a return label.

Alright guys,

Got the lens, it's optically in great condition, a lil' bit of internal dust but nothing to worry about. 

Things to worry about:
- Put two rubber bands on over the loose grip and it seems to be fine...but weather sealing is @ -1
- The part of the lens that houses the rear lens element moves slightly...and moves the rear element by about a millimeter.  This I took to be a huge problem, as if that moves while shooting my focus will change. (yes?)
- Did some real quick afmf adjustments...and +20 looks the best. (5dmkII) 

Optically it's still a beast, and I don't think I'll be returning it...but is there any way to improve on it's faults?  Please share any experiences you may have had!

Thanks guys!
Some of the third party camera repair stations still have a few parts, and they salvage whatever parts they can from severely damaged units. Check with them about possible repairs.
Check Fred Miranda, since there are several there who use the lens.

I focused on the word "mixed" and so far this looked the best of all the other adjustments

Your AFMA method is a formula for disaster.  Focusing on a book that way, the camera might grab anyone of the horizontal lines. 
Use a target designed to make sure that you are forcing the camera to autofocus exactly where you want it to.
Using software like Reikan FoCal is far better, but at least use something like this.  Its free!
Note how the center horizontal line is isolated so the camera can only lock onto the one place.  There is a lot of other good info there as well.  Proper setup and exact perpendicularity to the target is a must.

OH! O_O they do that?!
yes it was brand new... but I guess it was in stock for too long that lubricant dried up or something.
(just a theory to make my self feel better)

When I first called them about my first return, they told me I had to pay the way there and they would pay the way back...

Thanks guys! Ill call them up tomorrow and get this label!

If you used Amex to buy it, they extend the warranty by a year, as well as covering damage, loss, etc.

Call them.  Normally, they send you return postage.
Did you buy a new one?  Unless you are really expert, buying a used one can end up costing you a lot more than new.

Rotating turret lenses used to be common.  different focal lengths.  And, yes, they were allowed to photograph the president. (Calvin Coolidge ;) ) Times Change

EOS Bodies / Re: Lasers Can Damage Your Sensor
« on: August 17, 2012, 03:25:49 PM »
This has been known about for quite sometime. I believe it has to be in liveview as well when the laser hits it.

Im just curious how canon would handle a warranty repair on such instance as there is certainly no warnings from them about the possibility of this happening. So would it be user area and no free fix/replacement from canon?

Yes, the topic is two years old, and someone just now resructed it.  Maybe CR should lock all the old topics?

Third Party Manufacturers / Re: Sony NEX goes Full Frame!!!!
« on: August 17, 2012, 02:18:10 PM »

Sounds like it could handle E-mount lenses in crop mode, and would need alpha lenses for full-frame. Which is really actually good for users, cause Sony has some good A-mount lenses, where as I can't imagine any E-mount holding up to full frame. But with a crop mode, they'd be the same as they are on the NEX-7

The Nex Cameras are mirrorless, and that allows them to be smaller and thinner.  This is due to a reduced flange distance.
 A-mount lenses and a E-mount lens have different flange to sensor distances, so a adaptor would be needed to adapt aA mount lenses.  If the Camera was designed to use A Mount lenses, then it would need to be the same thickness as a DSLR, and e-mounnt lenses would not work, since they would have to mount inside the body to focus or have some sort of a adapter that had optics and made a poor lens really poor.
If A FF Nex were to appear, it would need all new lenses.

AF with those pins taped varies from model to model and body to body.  I taped several lenses and tried TC's on them with my 5D MK III, and they struggled or did not AF at all.  Only one, a old 70-200mm f/2.8L did what I'd call a reasonably fast and accurate autofocus with TC's stacked.  My old 40D would AF on almost any lens with TC at f/8 and usually f/11.  It just is unpredictable.

Their previous attempt at FF was a bust.  hopefully they do will not have the sensor to overheat issues from the built-in IS like the APS-C cameras have.
Their user interface is a nightmare and a good reason to stay away from Nex as well.  Sony does have a few good lenses, but only a few.  They are badly overpriced for non IS lenses.

Lenses / Re: best filter for shooting portraits (babies)

A Filter? 
In the days of film, when we did not have special effects of digital post processing, we had star filters and dozens of other special effects filters.

Now, about the only image modifying filters used are gradient filters to keep from overexposing the sky, or ND filters to allow you to use a wide aperture in bright light.  Polarizing filters will reduce reflections coming from water, and in any situation where the light is polarized.
UV filters, at least good ones should not affect your image.

Perhaps you can post one of your problem images along with the camera settings, and tell us what it is that you want to improve.  The term better looking is very vague.

Cameras can go bad, lenses can get out of calibration, there are lots of potential things that can happen.  You need to try to see if you can recreate the issue.
1D MK IV Low light with AI Servo, for example, is going to fail, the camera will shoot even if AF is not completely achieved when in AI servo.  Use one shot.  It may not AF, but will not close the shutter until its focused.  That might not be your problem, its just a possibility.
My 1D MK IV had very accurate autofocus, but struggled in low light.  Thats pretty well documented.  The 5D MK II is a excellent low light AF body (center point).

EOS Bodies - For Stills / Re: Canon GPS Options
« on: August 17, 2012, 12:33:17 AM »
Pretty much any GPS unit produces a log that can be downloaded to your computer and synched to your photos using the time stamp.  This requires that your camera have the correct time, which can be synched to a pc with Canon Utility such that its accurate to the second.
Some cell phones have this capability, and GPS data loggers are cheap.
