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.

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.

EOS Bodies / Re: Focus problems with the Canon 7DII?
« on: November 11, 2014, 11:21:38 AM »
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.

The old one had lousy handling, terrible optical performance from 300mm to 400mm wide open with the IS activated, and the IS was just this side of useless.
While I strongly disagree on the first point (I really like push-pull zoom) and wouldn't use anywhere near as strong words on the others either (having taken thousands of pictures with it and been happy with the results), I would definitely like better optics and IS and while the extra weight worries me (as I'd be hiking with it in the wilderness), I probably will upgrade mine if the new one is good enough. I'll wait for reviews first, though.

I like the push pull too.  That wasn't the lousy handling part.

I use mine wide open at 400mm all the time and it takes sharp shots.  The IS is a little weak I will agree.

He kind of reminds me of a Vally girl but I agree the ISO ability is most important to me.

Good catch Jon.  I wonder if the 5DIV or the 1DXII will be the sweepstakes winner.

having had the camera for a week now, I really really really don't like DPR. Lightroom is a far superior product and I hope they have an update soon.

I like it for its quikview feature. It opens up fast and is great for viewing rating and deleting. Also good if you want to convert without any additional auto corrections on top of what the camera does because the default conversion is the same as an in camera JPEG.

So why not just shoot jpeg?  If all we're doing is using DPR to convert from raw to jpeg, then why bother.

I'm using DPP to convert them from RAW to Tiff with the minimum processing possible. But with DPP I have no idea whats really going on "under the hood". Then I review them in Adobe Bridge. The TIFFs that interest me go through Camera Raw into Photoshop. Probably not the best way but so far it's working OK. I'll bring them all into lightroom once there is an update available. If someone has a better workflow I'd love to here about it. The OOC JPGs looked OK but really weren't suitable for evaluating a new camera.

That is my plan also.  Zero out the settings in DPP.  I plan on using the lens optimizer in DPP also.  I use DPP to sort, then to LR for final cuts and file naming and organization.  Back to DPP to convert to tiffs then PS to finish PP and convert to jpegs.

Got my 7Dm2 today. I have to be a bit critical here, it's a great camera but not perfect.

I had some issues with my Sigma 17-50mm 2.8. These lens worked fine on my 70D but I am getting very inaccurate focus on the 7Dm2, no matter what Micro AF adjustments I make.

My other lenses (85mm 1.8, 100mm macro, 10-22mm) work very well with the 7Dm2. So I guess there could be an incompatibility issue between these lens and the 7Dm2 body. I wish more people could test this combination.

Zooming in photos is a step backwards from the 70D. On the 70D I could just use my thumb to press the review button and use the two buttons next to the AF-On to zoom in and out, or just use the touching screen. On the 70D I can also zoom in a photo and from that point rotate the bottom wheel so the next photo would also appear zoomed in, very good to compare focus.

On the 7Dm2 I need to press a button on the left side (so I need to use the other hand) to review the photo, then press another button to be able to zoom and from there use the wheel. If I want to view the next photo zoomed in, I have to do everything again, rotating the bottom wheel won't do it like it did on the 70D.

That exposure scale that is displayed on the top screen of the 70D is now hidden inside the viewfinder on the 7Dm2. Not a big deal but just saying.

You will most likely need to get the Sigma rechipped.  This is common since Sigma reverse engineers the communications with bodies.  Your focus problem is highly likely a Sigma issue.
