I fell for the hype and bought a D800 from a small local dealer.  I also bought a top of the line 24-70mmG, and a very good 80-200mm f/2.8D and I already had a 50mm f/1.8D as well as several lesser Nikon and Sigma lenses.  I also bought a used  manual focus 200-400mm AIS, and a 500mm reflex, so I had reasonably good glass to try it with.
At ISO 100-400, the DR was amazing, clearly better than anything I've seen before, and i've owned all the high end Canon bodies.  However, as ISO's rose further, the noise increased faster than I thought it should, so NR was required in increasingly heavier doses. 
Then, the huge file sizes took 5-10 seconds to render, and just applying a bit of NR would take my PC 30 seconds to a minute using LR 4, while it took 1-2 sec for the 5D MK III files.  Since I had several hundered images taken in very low light to edit, it was painful.
Finally, after editing the first 1000 images, I'd had it.  CA's from the 24-70mm were horrible and even when lens corrections and CA removal applied, they were awful.  It was difficult to get sharp images without extreme care.
All the troubles for a camera that was really a studio camera optomized for low ISO's was not what I wanted.  I was also put off by no affordable lens that had comparable quality to my 24-105mmL, my 135mmL, or my 100-400mm L  The 200-400mm lens turned out to have focus issues, so I returned it.  I could have bought all three of the Canon L's I mentioned for the price of that lens.
I sold it all, except for the mirror lens which adapts to Canon nicely, and bought a refurb 5D MK II which I like much better as a all around camera.
So my conclusion is that its a fine body, but I struggled with the lenses and lack of high quality ones to match my canon lenses, and with high ISO's where the DR is actually poorer than the canon 5D MK III.
For landscapes and studio images, it is be a great camera.  If a PJ just uses jpeg and does not have to edit the images, he would like it, but the first time he sits down to edit 1000 raw images, he is going to learn something new.

The 5D MK III is a fine camera, but was not worth the difference in price to me, I had big time issues with not being able to see the AF points in low light, and since I always use the center point, the 5D MK II dos very well.
I returned my 5D MK III and managed to use the Canon CLP to buy a refurb for $1407.  It had about 385 shutter actuations, virtually new. I had sold my original 5D MK II for $1700, so I did ok.
At some point Canon will be selling them as refurbs, and I'll consider one then, if its on the CLP list of available bodies..

I love my 35mm L, but it definitely could be improved by a significant amount.  One of the weaknesses is the tendency to front focus closer than 5 ft.  I set mine at about 10 ft, which works fine for most images, but its off if I get close.
The depth of field is very shallow near mfd.

I've seen one possible explanation noting that since the lens has a stepper motor, it could lose synch with the camera body, and a remount/restart is needed to get the camera to synch up again.  The fix may very well be just having the camera body do a synch when the lens position does not match rather than lockup or generate a error message.
I tried another thing after reading the comment, focusing far away, then keeping my finger on the lens barrel so it could not move out to focus closely.  I could feel the stepper motor pulsing for about 5 seconds, then I removed my finger and it focused fine.  I also manually pushed it in while focusing, it just keeps working fine.
Could those with a problem mention the body they are using?

The local cave wardens would string up anyone using a flash.  They supposedly do a lot of damage.

I have a hard time believing that. From what exactly, a few microseconds of photons? Open a cave to the noonday sun for a week and it will change things, but a flash doesn't make sense. And if so, then how is a headlamp supposed to be OK?

There are low level lights though, so my 5D MK II/ 35mmL worked just fine.

I probably would have done better if I could have stopped. I was with a group that was marching forward.

Gardner cave in NE Washington State up near the Canadian Border.  Sorry for the poor photoshop job, I removed some obstructions from the image, and its a poor job.

Nice, I'll have to visit it next time I'm up there.
You are right, its my poor memory.  They prohibit you from touching the delicate formations, not from using flash
If you are ever up here, drop a e-mail and we might be able to meet.
Here is some damage, I thought the guide said it was from bright lights letting the alge grow.
 

 
 
Setting up a tripod - just too many people in a group, and not enough room on any flat places.  Mistly, the descent is on narrow and steep stairs cut into the rock, or steel stairs.  A  monopod should work though.
The 35mm L and 5D Mark II worked very well, but in some places, a flash would have been needed.  I restricted my photos to areas close to a light.

 
A small side vent that probably goes to the surface somewhere in the trees and rocks above.  The cave has been pretty well explored and documented over the years, but I only have my recollection of what the guide said.

EOS Bodies / Re: Question - Auto focus speeds & Battery Grips
« on: August 08, 2012, 11:55:19 AM »
The two lower-voltage batteries in a grip are used alternately, not simultaneously, so no boost.

I didn't mean to imply that with a grip it can increase the AF speed. I was referring to the fact that as a battery is almost completely drained it can provide a slightly lower voltage. So a battery grip, since it provides more total energy stored, can keep the rated voltage longer.
The power and voltage of a Li-on battery does not drop off like a regular battery.  Circuitry internal to the battery monitors it, and throws a electronic switch when it senses that it is nearly discharged.  Any drop in voltage is very small.
This is noticibly apparent in my DeWalt Drill Driver which uses a Li-on battery.  It drives screws, even difficult ones with full strength, and suddenly shuts off while driving a screw, it does not fade away like nimh ot nicad batteries.
There is a good reason for this, a Li-on battery cannot stand being fully discharged, if that happens, it cannot be recharged without some special equipment.  So the battery may shut down when it gets to 10% or so of capacity.

I started a similar thread earlier as I was looking at the 28-300 for the same reason- at certain events I find the 24-105 not long enough for some shots, and when I have the 70-300 sometimes I find myself wanting to go wider. From reading reviews It seems the 28-300 delivers comparable performance to the 24-105 at the respective focal lengths, but once you get past 100mm it can't deliver the IQ of a decent telephoto. (seems like very average or even mediocre performance, especially considering the $2500 price tag & weight).

My take is that this is a lens you use when you want a good quality general walkaround (focal lengths 28-100mm), but would also like telephoto coverage (100-300mm) when necessary, without the hassle of switching lenses. In that case, an average-quality shot is better than a missed shot.

It is certainly not a average lens, if yours has a issue, send it in for repair.

I played with mine some more today.  With the lens mounted to my powered up 5D MK II, I pushed the barrel of the lens all the way back, and did a lot of other screwy things, but it kept on working perfectly.  Apparently not all of them have the issue, or it is particular to certain camera bodies.
Or maybe just an early batch is affected?
I think mine is a early batch.

Although Canon has not been releasing codecs for 64 bit windows, Microsoft does release them, but slowly. 
The good thing, is that the codec covers multiple manufacturers.

No support for the 1D X though.

I think Epson is the one with heads that clog.  My 3880 takes one day before the red head starts to clog.  In two days, the yellow clogs as well.  I run a cleaning every other day to keep from any serious clog.  Expensive!

Well heck.
I guess I had that happen on my 60D.

I was fiddling around a bit absent minded & the lens moved inward with a fairly light pressure made by my finger. I saw it move about 1/8 inch  :o (oops) & thought that didn't seem right.

I had to pop the battery out & back in to get functionality back in the lens ( didn't try re seating the lens ). It seems it just froze up causing no damage  :) . Definitely sensitive, glad their doing a fix because it could be a pain in the butt ox if it happened often.
If you push the end of the lens barrel to put on the cap, or whatever, it will telescope in, some may take more perssure, but all of them move.
What should noot happen is for the camera to lockup when it senses a lens movement.

I tried to see if I had the issue, mounted mine to my 5D MK II and pushed on the lens, and of course, it would not autofocus because the barrel could not move with me pushing on it.  I removed my finger and it worked fine.  I tried squeezing the barrel too, but that has no affect.
Then, it dawned on me that what they must be saying is that some cameras lock up when you do not allow the lens to autofocus by pressing  the focus barrel or focus ring on the front of the lens.
Thats why the fix is firmware for the camera.  nothing wrong with the lens.

EOS Bodies - For Stills / Re: How rugged is my 5D Mkiii?
« on: August 06, 2012, 10:53:22 PM »
There is no standard to define ruggedness or protection.  One camera might survive a big time hit while another fails with a little bump.
The trick is where to provide the bump.
It all depends on the individual and the way you use the camera.  If you thiink it will get dropped or banged around, one of the protective covers will help.  However, a 1 series body is definitely built to take a licking.
