Its just another sign of tight corporate budgets due to slowing camera sales.  Rebadging a old design and adding minor upgrades every year is expensive, in terms of changing all the advertising, literature, software, stocking warehouses, discounting the previous model, etc. 


Look for longer intervals between models.  Canon seems to be very good at squeezing every possible dollar out of a design, so they do well when everyone else is struggling.  From a business standpoint, that's smart. 


I'd rather only see new models when something significant is changing.  I expect that the 70D technology, or other new sensor technology will trickle down eventually.  You are not going to see the high end features go into a base model.  Eventually, they will appear, but it will take a lot of time.


I can remember when a heater was optional in a new car, and forget about air conditioning or radio, or many features like power steering that are now pretty much standard.

You can easily check for shutter failure, fire off several shots at 1/8000 sec shutter speed.  Thats where it becomes apparent.


If you are using a flash (you did not say)  its possible, but not likely to be totally black.

The storage and using of Accumulators depends on the Type of Accu.

The older NiCD or NiMH get´s Memory effect if they often discharged not completely,
some Chargers are able to discharge the Accu befor charging to avoid the Memoryeffekt.


Greetings Bernd



Thats a old myth, It sold a lot of special chargers, even the Canon charger for the old 1 series could discharge a battery and then recharge it. proper investigations of this have never found it to be true.  I had some very good scientists on my staff, and they tested lots of batteries.   It only happens with a special material that common batteries like we use do not have.

Purple fringing can be removed in lightroom.




What about DPP? I was never able to figure out how to reduce PF to that degree. (I don't have Lightroom)


LR5 has a tool for removing LOCA's.  DPP has a lens correction tool, but I don't know if it works as well on that image.  I have DPP4 which doesn't work with RAW from the 5D MK II yet.


What LR is actually doing, is to remove the exact purple shade of the color from the image.  This usually is not noticible, because its a very narrow filter.  But if there is something that exact shade of purple in the image, it will no longer have any color.


DXO also removed every bit of the purple fringe, and it was easier to use than Lightroom for this.

Thank you! I see prices for 7d are going down quite rapidly these past weeks. Would it be better to get 7d instead of 70d? Do you have any experience with third-party macro ring flashes? I really don't want to pay $500 for Canon's one.

Will check the deals on Nikon and maybe Pentax and see what would be the best bang for the buck.


Canon sold a 10D with 100 macro and ring flash that is still the standard in many dental clinics.


I'd suggest a 70D plus a 100mm L  with a ring flash as being a little more modern.  The live view insures that you get what you need in one shot, and the IS helps stabilize the image so you can focus on the right spot.


With the 5D MK I, you will need a longer macro lens, look for a 150-200mm macro lens for the approximate same FOV on a FF camera.


All the Macro lenses tend to be excellent, so don't fuss over the brand.


I'd go for the better live view performance of the 70D.  Since it uses the sensor for phase detect autofocus, it does provide excellent autofocus accuracy and speed.  The 70D has some features like many FPS, but you will want focus speed and accuracy more than FPS.   The 70D also contains much of the 7D Autofocus module when not in live view, so you basically lose the FPS and the studlier build.


A 70D can be had for less or the same as a 7D.

Are they NIMH? 


A freezer is good for storage of NIMH.


http://www.ehow.com/how_7234784_store-nimh-batteries.html



Aging of batteries is a chemical process, and freezing them pretty well stops the process, so that there will be little ageing, if any while in the freezer.


The life is usually considered to be a number of charge / discharge cycles, but storing them fully charged does place stress on the dielectric, so store them with only a small charge in the freezer, and don't worry about them.


Its basically the same reason that we stored film in the freezer, the chemical process was halted, so film degraded very slowly and could last dozens of years.


If you only use your camera occasionally, just freeze two of the batteries.

7D images do have a grainy look, starting at about ISO 800.  I reprocessed mine with Lightroom 4/5 and they look a lot better.


Try using live view with live autofocus and a sturdy tripod at a reasonable range, say 10M.  If the image is sharp, then either the lens or the body or both can benefit from adjustment.


Canon India probably has their own policy regarding gray market.  Canon USA repairs them, and even seems to honor the warranty.  Each country is different, so call and ask. I'm not even certain that they can tell where it was sold.


My 7D was fine with all my Canon lenses, no issues there.  At the time, I had a 70-200mm f/4 L IS which was wonderful.

sanj, here are my test results using the following method:

Camera settings
-5DIII with battery grip - 2 fully charged batteries (grip doesn't matter) or 1D X
-Freshly in-camera formatted CF cards



Thanks for taking the time to test ---




BUT there is a fundamental problem with your test.  Formatting cards in camera does nothing but mark the fat table to tell the camera that the memory can be written over, and make it disappear.  Thats why card recovery utilities can recover files, no actual formatting of the card was done.  Its also why card testing sites do a low level card format before each test.


 Depending on the memory controller, it may choose to write over cells with data in them, thus forcing a slow erase, or it may write to empty cells if there are any. Each run will be different.


The results have only a remote relationship to memory speed, but it is related to the contents of the memory card.


Do a low level format or card erase before each test.  That will put a card in new condition with no data on it, so it will not have to erase data before writing.  Its a slow process, but then, the card tests will be something that is accurate and level the playing field.  It can be done in a card reader attached to a computer.


You may, in fact, get the same or similar results, but why not do the test correctly?
That's a good point and my reasoning behind the format of the cards was just to clear all of the free space - realizing that I'm not actually deleting the files, just telling the controller that the space can be overwritten. 

In my experience, low level formats have very little effect on read/write speeds, but once a storage device drops below 20% free space, there is a significant effect on speed, increasing as space runs out.  CF cards might work differently, but I think Canon would offer that as an option (like they do with SD cards) if it made much of a difference.

Also, I was really just testing for myself to see if the cards were worth the money - but thank you for the feedback :)


True, but its a matter of not knowing the actual affect of a used card, or even how much was used.



It is a huge impact in SD cards, not so much for CF cards.  That's why Canon has a low level format option for SD cards.  They drop write speeds to the range of 5 -20 MBPS.  Those that pay for and think they have super fast write speeds with SD cards are often fooled by the hype.

I find that PRIME does two things really well - it keeps colors saturated and retains detail.  It isn't as slow on newer machines - my shots typically process in around 90-180 seconds on my PC, which is a Intel Core i7 I7-4770K 3.5 GHz Quad-Core Processor with 64 GB of RAM that I built. 

Agreed.  I generally use it for shots at ISO 3200 and higher. 

It will be getting faster soon.  On my >3 year old 17" MBP (I really wish Apple would bring the 17" back!), with a 2.53 GHz Core i5 (dual-core) and 8 GB of RAM, the current version of DxO (as in, double-digit, that I use to process images of birds like Nightingales, Ducks, and Anhingas) takes less than 2 minutes per 'typical' image (in the ISO 4000 - 12800 range; higher ISOs take a bit longer).


I have the current i7, and prime takes only about 5 seconds to update the display.  However, exporting seems to take forever. 


I'm planning on a upgrade this fall if the new processors are significantly faster.  I have the i7, 24GB Ram, and a 500 some GB Samsung SSD along with a 3TB Hard Drive.  Its not the fastest, but no slouch either.

For the intended users, the lens is fine, its not a Pro lens, so don't expect $2500 performance.

Here is a before and after with Canon's Champ of purple fringing, the 85mm f/1.8

Yes, they started sending me surveys immediately.  Some of them were under NDR, so I won't reveal them.  They might raise more than a few eyebrows, and they are merely surveys, nothing factual.
You should have seen the surveys they sent out after the Creative Cloud response :) .

I'm on a few other advisory panels like this, but most of them are pretty dull surveys.  Some pay me for my time, which is nice.


Yes, I've received a lot of free software for this and for beta testing.
Software companies are very good to their testers - I wish the two car companies that I'm on panels for would be a little more generous!


You mean Tesla and Lamborghini ;)

EOS-M / Re: How Much Would You Pay...
« on: July 14, 2014, 10:09:02 PM »
Right now, its not a matter of cost, its a matter of technology being able to match phase detect. 


The $259 selling price for the current ebay deal speaks volumes.  They don't sell.  Sure, there might be a few who want one, but Canon depends on large volume sales, and it was a big flop in the US and Europe.  In Asia and Japan, it sells well.


This is a pretty good example showing how different the market is in Asia and USA/Europe.  DSLR's sell well everywhere, so expect more of them.

Pricewatch Deals / Re: EOS M + 18-55mm for $250!
« on: July 14, 2014, 03:44:26 PM »
I was very tempted just because of the price.  But, then reality kicked in, and I passed.  I've a G1X MK II which would duplicate most of my potential usage, and it focuses very fast. 


My 5D MK III would be the camera for serious shooting.


When mirror-less gets fast focus, tracking, and a large body with FF sensor, that can replace my 5D MK III, I'll be tempted.
