I occasionally find that when I want to set a fixed aperture and shutter speed , that auto ISO does not give a correct exposure.  I can manually set ISO, but exposure compensation is very useful. 
 
The issue is that I forget to reset it, and then, the next time, exposures are off.  We need a auto reminder to automatically automate the auto exposure compensation.

Yes, he is now a Canon explorer of light, so he gets to try out new pre-production models.  I'm convinced he is so good that he could make a coke bottle work for a lens.

Having been in the manufacturing business for over 30 years, I can say that changes to products do happen.  Materials are changed due to price or availability, machinery wears out and is replaced by faster and more accurate machines, subtle changes and process improvements happen frequently.  However, changes that affect the form, fit, or function are not incorporated unless there is no choice.  When that happens, you end up with one of those dreaded situations where replacement parts vary by serial number.  If a new process fails to work properly, then its a mess. 
 
Even changing component suppliers can make things different, electronic parts are phased out every few years, and substitutes must be found.  I used to do this on a daily basis for a large manufacturing company.  Sometimes, a critical part can cost a huge amount of money to tool from a different supplier.  I remember having to source critical parts for a cruise missile that was long out of production.  The cost per part for a hundred pieces was astounding, I forced the supplier to fully test the part after I discovered that their process for making it had never really been stress tested, it failed, and a redesign had to be done.  That led to a recall of 10's of thousands of parts that used the same process commercially.  They started failing about 6 months after my testing / redesign was complete, so the manufacturer had already started producing replacement parts.  We had notified the commercial users, but they weren't concerned, not until their customers started complaining.
 
So, I would expect tighter tolerances due to process improvements, and possibly cheaper materials and plastics that are cost savers to the factory.  The end user will likely not ever see a difference unless he were to test a large group of lenses and see less variation, for example.  Since there is no historical testing of large numbers of lenses that is reliable, we won't have hard evidence.

EOS Bodies / Re: EOS 6D Mark II to Move Upmarket? [CR1]
« on: October 14, 2014, 10:37:38 AM »
I personally think that the 6D is just fine where it is, the issue may be that consumers think there is something wrong because it sells for less.  Bring the 5D III to $2500 and adding a 3D at $3600-$4000 makes more sense.

If I did not already have the 5D MK III, I'd probably have bought a 6D, since it does what I need.  I bought a 5D Classic on a whim for $350 recently, it is a great camera too.

I had a D800, but my Dell i7 based pc could not reasonably handle the large noisy files.  Now I'm a couple of generations newer, and the large files are not a issue, so I'll be looking at large MP cameras but really am not in need of one.

Lenses / Re: Anybody still holding out for a Canon 24-70 f/2.8 with IS?
« on: October 13, 2014, 10:12:51 PM »
Can't speak for the Tamron, but the Canon 24-70/2.8L II is a wonderful lens.  Personally, I generally set a minimum 1/125 s shutter to stop the random motions of even 'still' subjects, and for landscapes, etc., I'm using a tripod, so the lack of IS doesn't bother me.

I'm basically in the same situation, Only in extreme low light do I drop the shutter speed a little.  A Crop camera might benefit because of the 1.6 factor, but for FF I haven't even thought about IS.

What about video?

I don't use it for video, I've been there and done that.  A dedicated video camera is the way to go.

EOS Bodies / Re: 7D Mark 2 Preorders "sound off"
« on: October 13, 2014, 07:45:09 PM »
All the big players are saying "around November 15", so I would not trust any earlier date....
WHO ARE THE BIG PLAYERS?? are u referring too B&H and Adorama?
well im trying too get this camera in HAND AD FAST AS POSSIBLE without relying on FEDEX AND UPS and there super slow "even with 1 day or overnight shipping options" i feel more comfy goin too B&H and getting mine ADORAMA NO OFFENSE DEY SEEM hella slow at getting the newest cameras and there store is super small :(

Actually, Adorama got far more 5D MK III's early on than B&H.  Canon was angry with B&H over some undisclosed offense and limited their shipments to B&H.  Adorama had always delivered my new models in the first batch received from Canon.  The cameras are shipped according to the time you place your order.  If you ordered early, you should get one of the first batch to arrive.  If you order now, it might be well after Christmas, or it might be sooner, it depends on the backlog.  A small local dealer can often do better on delivery. 
 
As far as taxes, they are owed according to the state you live in, not according to where you buy it.  1 day shipping is 1 day.  However, it takes time for a dealer to process thousands of orders so they may not ship or make them available in 1 day.

If you ordered one the first day, it should arrive in the first batch.  Amazon usually delivers a month or two after Adorama, but it seems to improve a little each year.  I think Canon gives priority to real camera stores. 
 
I pre ordered the original 7D, there was a lot of hype, but I already had a 5D MK II, and it was a big disappointment compared to the FF. I fully expect the same thing, lots of hype, but, in the end, its a crop camera sensor and limited by the area of the sensor.

How is Amazon not a real camera store?  They sell a ton of photography gear.  In fact, they have more options than any local camera store in the Phoenix area.  They may not quite have the selectivity of B&H or Adorama, but I guarantee you they are more of a camera store than the vast majority of camera stores (what you think of, at least) out there.

To me, a real camera store has at least one pro or knowledgeable person that can answer questions, demonstrate a camera, and intelligently discuss your needs.  Even Best Buy has some help that knows what they are doing.  Amazon, Costco, Walmart, Sams, and the like just push merchandise out the door.  They are not Camera stores, they do not hire photographers. 
 
The point is that just because Home Depot sells a zillion toilets, for example, they are not a plumbing store, they often stock the wrong parts for the job because the store buyers just buy what the manufacturers sell them for the lowest price.  I had to redo my water well system recently, and went to Home Depot to get a pressure switch and a pressure relief valve.  In their well section, they stock this stuff, the wrong type of pressure switch, and a pressure relief valve intended for air compressors, not water systems.  Its dangerous when they sell you a 250 psi relief valve when it should be 75 psi, sometimes 100 psi.  The wrong one could cause a disaster. 
 
You might read this thread about the 5D MK III's and Amazon pre-orders, its a story repeated for each pro or semi pro new model.

I have been a Canon user my entire life.  I love the product, including DPP which is my RAW converter of choice.

I presently shoot with a 1D Mark IV and a 5D Mark III, which are fully supported by my present version of DPP.  The 7D Mark II requires that I update my DPP.

Here is my problem with that.....

The newer version of DPP does not support my operating system.  I run Vista 64.  Updating my operating system requires that I go to Windows 8 which needs a clean install.  Huge job. Okay..... rant over.   :D

I would suggest upgrading to Windows 7 if you upgrade.  Windows 10 will likely be out early next year.
 
I'd stay with your 1D MK IV, its still well ahead of the 7D MK II.  Don't fall for the hype.  If Keeping a old OS prevents you from replacing the 1D MK IV, Canon did you a favor.
 
I'm also your age, I reinstall my OS once a year.  To make it easier, I create a disk image on a spare hard drive to have as a backup.  Then, I only have to update programs installed or updated since the previous image was made.  That helps reduce the big job.  I've bought two new Dell XPS computers with Windows 8 in the past year.  I just pull out the hard drive with Windows 8, put in a SSD and install Windows 7.
 
Right now, DPP4 is pretty bad, you are not missing anything.

Reviews / Re: Jeff Cable's 7D2 & High ISO Look
« on: October 13, 2014, 01:42:42 PM »
This is a case where I'll wait and see what the real ISO capability of a production camera actually is.  I'd guess it will be around 1000 - 1100.  The tests I've seen so far indicate that the real raw ISO is the same or a hair better then the 70D, but for jpeg output, the dual processors are able to apply better NR, closer to what a home computer can do.  That's good news for jpeg users.
 
I hope all the professional testers are wrong, and its better than the images they took, but they have the most accurate tests.

Technical Support / Re: 100-400mm will not stop down
« on: October 13, 2014, 10:28:30 AM »
Try stopping down the lens, and then pressing the DoF preview button. If the aperture blades do work, the image in the viewfinder should get darker. You can also look down the barrel of the lens and see the aperture blades while that button is pressed (again, if they're working). You can confirm how this should work by trying it with a working lens.

If they're definitely not working, it could be worth cleaning the electronic contacts on the lens, but failing that, I'd suggest a return trip to a canon service centre for that lens.

+1, its easy to do a check.
 
The camera gets feedback from the lens about the aperture responding to commands, and gives a error if it does not feedback the requested aperture, so look at it, set it wide open, then reduce the aperture and press the DOF button.  It will be a obvious change.  Cleaning contacts is all you can do.

EOS Bodies - For Stills / Re: Canon 7D Mark 2 Rolling Review
« on: October 13, 2014, 10:16:42 AM »
As Steve said... Rouse is not exactly unbiased and independent. When all the canon explorers say its too good to be true... Well don't bet the farm on these reviews is all.

Andy mentioned that he thought this camera could beat the 5d3 on high ISO. I'm not drinking the punch yet.



Photos and tests have been out for quite a while now, it basically matches the 70D for high ISO, a stop behind the 1D MK IV, 2 stops behind the 5DMK III.
 
 
You can see for yourself.

Lenses / Re: Canon 400mm f5.6 in combo with the 5D3
« on: October 13, 2014, 09:57:16 AM »
It all comes down to the type of sports and the lighting.  If you have a 1/2000 shutter speed and low light, then the high ISO will reduce resolution, but the 5D MK III does reasonably well at up to ISO 12800.

EOS Bodies / Re: AA Filter: Still Relevant, Marketing Ploy, or Obsolete?
« on: October 12, 2014, 11:55:32 PM »
There are different kinds of AA filters.  They are usually combined, but some leave out the mechanical filter and use digital filters instead.
 
Basically, a AA filter is a lowpass filter that eliminates MoirĂ© by eliminating frequencies above the Nyquist frequency.  A perfect filter would be like a square wave and cutoff at the exact frequency.  In reality, the frequency cutoff is a roll off function, so it affects frequencies below Nyquist, and still allows some above Nyquist to pass.  A Combination of digital and optical can give a sharper cutoff, so there is also a filter in the electronics processing the data from the sensor.
 
You can eliminate the optical filter, and do as good a job as possible with the digital filter, but it will let more high frequencies thru, and thus, more MoirĂ©.  Its a complex balancing job, but is made easier by high MP sensors.
 
There is continuing work going on because of the big payback.  Here is a older paper describing the development of a combined optical and digital filter.
