Canon General / Re: Does Canon really deserve this?
« on: November 22, 2014, 09:09:58 AM »
You have technophiles who want to keep up with the Joneses.  They may or may not be users or simply trolls. 

Then there are those who believe that the world revolves around them, whether they will admit it or not, and expect to see equipment that they want.  If it is not produced they whine, snivel and bitch to the max.

The world in general has become so accustomed to convenience that most do not wish to spend the time to produce art.  They want it produced for them and then put their name on it.

You must remember that those who are willing to complain far out number those who will complement.

So, having made my rant/shared my thoughts I am quite happy with Canon and will learn to use my equipment to the best of my and its ability for whatever application I wish to attempt.

EOS Bodies / Re: Focus problems with the Canon 7DII?
« on: November 17, 2014, 09:14:09 AM »
After seeing the posts related to focus issues I fabricated a flat target from 5mm thick yellow craft foam and narrow black masking tape so I had a high contrast target. Target was set up about 10 meters from camera; camera on tripod. Using the tamron I took shots at 150 and 600mm with MFA adjustments from -10 to +10. None of the shots with the7D2 where in focus. I put the lens on my T3i and, without adjustments of course, took the same shots. Again, none were in focus. Finally I tried with my 70-300L with similar out of focus results.

Apparently I built a focus target that cameras can't focus on. Will contact USAF to see if they want to use it in their stealth technology.  8)

Wow Rod, you gave me a nice grin to start the day.  Sorry you are having trouble.  It seems folks with tamrons and sigmas are unfortunately having problems.  Might need the lens reprogrammed to work with the 7D2.

I have decided to return mine for an exchange do to focusing issues after trying all of the suggestions given to others and anything else my twisted mind could come up with. 

Hope you can work your issue out quickly.

Bumping this one back up, now that the Unicorn II(TM) is on Amazon.   Did Canon overstate it, or are people happy with the lens additions?

Those who were looking for the lens will be happy those who were looking for another lens that they felt should have been produced will not. :o

We hear often about a camera "not perfect' not creating "sharp images" and I can't quite fathom why.  If it's a malfunctioning camera or lens, there is time to return it.   

Some of the critiques on here make no sense to me -- it examines the electronic component of an image, finds a micron measurement that differs, and then scream "foul' and "not as good", and "this one is better' at "Some" part of the technology.

Maybe it's me, but I have yet to buy a camera or a lens that fails to suit the images I produce.  Not every image is perfect, and that has more to do with the photographer or the scene than the equipment.   I shoot lots of 'keepers' and lots of 'rejects' but I blame the rejects on myself, or the subject, not the equipment. 

And I'd imagine some malfunctioning equipment arrives at the retailers -- and a buyer gets one, returns it, and gets a replacement or repair that works fine.  but, I'd bet the 'rejects' are few, and some even imaginary, in fact, maybe.   

When i buy a piece of equipment, I run it thru some tests, push it out hard to where I need it to perform, then get on with clicking the shutter -- if it malfunctions with a defect (I've only returned ONE camera in twenty-five years, and NO lens).   So, either I suck at evaluating my photos, or I'm getting good images ... but once I initially check a piece of gear, the I use it until it fails ...   Otherwise, I'd spend all my time testing and no time filling the wallet that got flat buying equipment.  :) :) :)

I think you are spot on.  I think the "soft lens" comes from it isn't taking the photo the way I see it or from user error.  Complaints far out number complements and if someone sees a statement enough times it becomes validated by the sheer weight or repetition.  I know that on this lens many of the "soft copies" came from using filters.   I can tell you from experience that many long telephotos and screw on filters do not get along well no matter how high the quality of the filter.  Also there may also be the issue of the lens and body needing MFA but the user not having a body that can do that.

I only turn it off to switch lenses.  The card doesn't come out except for rare instances.  I don't think I turned the camera off to do this.  Any issues from switching cards without turning the camera off?

EOS Bodies / Re: Can the new 7d mark ii challenge the 1d mark iv?
« on: November 13, 2014, 09:53:34 AM »
Personally, not only do I think they are both aimed at quite different markets, but I also think it very much depends on what you are used to.

For me, once you get used to the 1 series it is difficult to move away. I like the size, weight, quality and the way it balances perfectly when using big white lenses.

If I was forced to choose between the 7D ii and the 1D Mark IV I would choose the 1D Mark IV.

Throw a battery grip on the 7D2 and size, weight and balance is probably about the same.  Quality we would need your description of quality.  The 7D2's weather proofing is second to the 1DX, it has an all magnesium frame as does the battery grip from Canon.  There is about 1 stop better ISO performance on the 1DIV and a shallower DOF due to the larger sensor.

Beautiful shots Helmut.

Looks to be a potential for a nice IQ improvement.

EOS Bodies - For Stills / Re: Canon 7D mk11 is this for real or just hype
« on: November 11, 2014, 11:54:02 AM »
I was reading on the internet, I usually don't bother but this really caught my eye, are we that far behind these days.?


No, were not as far behind as DXO indicates. The 7D II "SCORES" poorly on DXO because it hasn't gained anything on the low ISO or color depth front. DXO scores are a very bad way to compare cameras, always have been, always will be.


Ignore DXO scores. Look at the measurements. Look at the ISO chart, and compare it with the original 7D chart (the likely upgraders to the 7D II). What do you see? Has anything improved?


The 7D II did gain about 2/3rds of a stop improvement at higher and very high ISO settings over the 7D. It did not gain at low ISO as it still has roughly the same read noise, and it barely gained on the color fidelity front. Until Canon does something about their readout system, I wouldn't expect the low ISO or color accuracy performance to improve. Canon has a distributed system...the sensor is only one part, there are additional off-die components involved, and I believe it is those off-die components that are really holding them back (and, if the information is correct, those components are not even manufactured by Canon, they are relatively cheap third party components). That's low ISO, though, just low ISO.


(Personally, I was really hoping Canon would do something special with the 7D II sensor, something way out of "normal park" for themselves...but they did not. It would have been nice to see Canon show some real out-of-the-box innovation on the sensor front, but as far as low ISO performance goes, it's pretty run of the mill for Canon. I found that quite disappointing when the 7D II was first released, but in the grand scheme of things...they improved the sensor where it mattered for the 7D II's primary use case.)


The 7D II DID make gains at high ISO, and they are very reasonable gains. The 7D II sensor Q.E. has improved, the total sensor size also increased a little bit (the 7D II has more of a 1.55x crop at 336mm^2 rather than the classic Canon 1.6x crop at 330mm^2...slightly more total sensor area, better high ISO performance), and the FWC increased (by almost 10ke- over the 7D, which is quite considerable, and even 4ke- over the 70D. So, despite the fact that the 7D II barely gained much in terms of total DR at ISO 100, the increased charge capacity of the pixels is still going to mean lower photon shot noise, which is going to mean an improvement in IQ at midtones and highlights.)


Those improvements at ISO 100 ultimately trickle down to the higher ISO settings, allowing more charge at each setting, which is probably where most of Canon's high ISO improvement comes from: more light, less gain, lower noise.


Are the gains as much as many of us hoped? No. Are they reasonable gains for the intended use case for the camera? Yes. Plus, throw in all the rest of the improved features...65 cross type AF points. Unless the new AF system has the same jitter issues that the 7D had, that should be a winner.

Great description.  I haven't noticed any jitter like the 7D yet on the 7D2 but I have only had one day with it.  Metering is much better, focus stays on much better and recovers faster if it is lost, focus is quicker if you have good contrast.  Everything seems improved from the 7D.

One of the reasons I prefer to wait a while before buying stuff.  I am appreciative of the consumers who volunteer to be the company's beta testers...   ;D

It is sort like a walking through a mine field... let someone else volunteer.   ;)

But then you lose the sense of adventure, the adrenaline rush and all that stuff.  I am a Beta tester this time BTW.  So far so good...knocks on wood.

I seem to be having similar issues as the OP. I got mine on October 30th along with a brand new canon 50 1.4 and got right to fiddling around with settings and taking pictures of my cats, that night I got quite a few soft/out of focus images, but figured it was being new to the camera and lens or maybe that it needed afma. the next day I shot some photos of people dressed up for Halloween with my canon 17-55 2.8 (which I have had for a while and had no issues with on a T2i body) surprisingly still had lots of soft/out of focus images that mostly seemed to be front focused. I figured afma would be the solution, so I attempted to perform afma on all my lenses with the help of some online articles. after that results with my 50 1.4 and other lenses seemed to improve, but I still was getting a relatively high number of out of focus images for non action shots of people and my cats. (all of this was with one shot mode)

next I got to shoot some action shots at a bike race using AI servo mode and zone af with a canon 70-200 F4L. with this setup I had very few out of focus shots, despite tracking fast moving subjects. I was very pleased with the camera for action.

I continued to shoot non moving subjects in one shot mode and continued to be disappointed with the results, so I figured another attempt at afma might help, this time with the help a commercial afma setup tool. (the datacolor Spyderlenscal) with this tool and my canon 400 5.6L in one shot focus mode I am getting frustrated trying to get it calibrated, if I get it set when coming in to focus from mfd setting then it is significantly back focused when coming into focus from infinity. I have found however that when using ai servo mode I get sharp images either way, it's almost as if the camera thinks (in one shot mode) it has locked on before it has fully focused and stops, leaving a margin of error. but in ai servo mode the camera continues to hunt a tiny bit until it has found perfect focus.

I will be interested to see if the OP's camera was indeed a lemon (looks like that is the case) or if it is just a matter of getting used to the camera and properly performing afma.

I'd send it back. So far, my photos have been much better with the replacement.

I agree with sending back if you get inconsistent AF.  I just got mine and it appears to be very consistent.

While Thom does not lambast DXO mark I do believe he points them out for what they are.  A business trying to do a thriving business without looking so.  If they were to eliminate the overall score and not make suggestions on equipment they would raise their stock for some but would loose with others.  If Canon is not a client for their testing programs then they are most likely to paint their other clients in a better light to not lose them.
