5DSR Focus issues

My apologies if I did not go back far enough to see any previous discussion but has any forum members had issues with the 5DSR regarding focus issues. I've experiences an ongoing frustration with this body used on my Canon 600 and 800mm as I use it for wildlife "stills", (i'm use 1DX for action on 400mm f2,8 IS MKII). The 5DSR seems a very hit and miss affair but when you really magnify the images down, some are so sharp you could cut yourself and others are as if looking through a coke bottle or putting vaseline on the objective lens. I can put the focus point bang on the animals eye and yet at 1/4000th sec and f6.3 and resting on window or monopod ...yet they're soft. I took it to CPS in Dubai and they say they adjusted the camera but its made no difference. I tried the camera settings to adjust for the particular lens used but no appreciable difference. I've tried a little experimenting with adjusting front or back focussing but nothing scientific. Its just frustrating having to take more than you need pictures on the hope that one is a keeper.

I just wonder if because of the high pixels, that it shows what ever imperfections in my settings or shooting style. I don't get any issues with my 1DX on same lens's so it has to be the 5Dsr body. Anyone care to comment or share experiences ?

Thanks
Mark

1Dx mk2 arrived

Two 1Dx mk 2 arrived today.
Unreal high ISO performance and fast as hell.

For those of us who need SD cards at times, save your cash, the DeLock CFast to SD card adapter is not compatible at this time. Hopefully in some future firmware update that will get fixed.

5D4 image quality given 1DX2 Results

In the previous generation, the 5D3 only had better IQ over the 1DX due to resolution alone at low ISO.

Will the same hold true again? I think so.

The 1DX was better than the 5D3 at about 400 ISO and beyond. Depending of course on how picky (discerning) you are.

It is hard to imagine that Canon would show up the 1DX2 with a 5D series body. We certainty aren't getting better high ISO performance. At best, we might get a little better low ISO DR? Maybe, maybe not. Depends how they "tune" the sensor.

The 1DX2 has, for Canon, along with the 80D, shown a huge, huge leap in DR performance. ISO is improved, but not a whole lot. Which makes sense, as this is a very difficult area to improve on. And historically, a 1/3 stop per generation is typical. With 1/2 stop or more being an exceptional improvement.

All that said, we now know that unless Canon changes the way they do things - the 5D4 will be close, but not better than the 1DX2 image quality which is readily available online now. Nikon has never done it that way. They're ok with some cameras being better IQ at a lower line. Nikon obviously specialized with their D5 sensor. Going for all out high ISO performance, and giving up DR and resolution. I think that is a big mistake on their part. This is because all the D5 has going for it is the sports features. Speed and high ISO. In sports, Canon destroys Nikon. More speed, superior glass - things that matter most. As well as superior AF. And just a hair less high ISO performance, it is literally splitting meaningless hairs at that point.

Nikon I believe underestimated the number of photographers that use their flagship for events that are not sports. This is for two reasons, because the D810 is too slow, has bad high ISO, and makes gigantic files. Not to mention crappy controls for fast paced environments. Nikon lacks a 5D3 events jack-of-all-trades workhorse. D750 is kinda it now, but it's got some weaknesses. Serious pros turn to the D4S for weddings, concerts, and all events and general purpose use.

When it comes to video, Canon is slaughtering Nikon at the flagship level. Thus, the 1DX2 will be more successful than the D5.

But back to the 5D4 -- the main competitor will be the D750. 24mp. Very good sensor. But the camera feels like a plastic turd. Terrible ergonomics. Bad reputation with recalls. Nikon had a real chance to take over the event camera world, and failed. Canon, despite being horrifically slow to innovate - and given the 1DX2's performance, has only "caught up" NOT surpassed the competition, it will again come down to a choice -

Do you want the utmost in IQ, yet sacrifice in literally all other areas? Get Nikon. Happy with just a few percentage points less IQ that never show up in real world use - but gain advantage in nearly every other category? Go Canon.


As far as the rest - 5D4 will have the same 61pt system, will it be as good as the 1DX2? I doubt it. Weaker in processing or logic somehow. 24mp is what is rumored. That is good. More DR, but not as much as Nikon but close. Sounds good. 7fps.

Not much left to know if one is looking to make a decision before announcement. Unless there's some shocker surprise ( unlikely ). You pretty much know what you're getting.

The 6D2 might be the only mystery. As last time, it's sensor was better than the 5D3. It was a sort of 1/3 generation newer sensor.

Canon EOS-1D X Mark II Studio Tests

HTML:
<a href="http://See the full studio test">DPReview</a> has posted their first studio tests with the Canon EOS-1D X Mark II. They have tested RAW dynamic range performance as well as ISO to give you an idea just how good the new 20.2mp Canon sensor is.</p>
<p>Dyanmic Range</p>
<blockquote><p>The Canon EOS-1D X Mark II shows very similar amounts of noise to the excellent sensor in the Sony a7R II up until a 3EV push, with the Canon dropping behind after a 4EV push. It’s a similar story against the likes of the <span id="imageComparisonLink2429" class="linkish">Nikon D750</span> or <span id="imageComparisonLink2430" class="linkish">D810</span>. This means that the darker shadows in a processed image would be slightly cleaner in images from these cameras, after contrast adjustments or a less extreme push.</p>
<p>However, this performance is noticeably better than the <span id="imageComparisonLink2432" class="linkish">Canon EOS 5DS R</span> and, significantly, better than the 1D X II’s most direct rival: the <span id="imageComparisonLink2433" class="linkish">Nikon D5</span>. <a href="http://www.dpreview.com/news/8090146652/canon-eos-1d-x-mark-ii-studio-tests/1" target="_blank">See the full studio test</a></p></blockquote>
<p>ISO Performance:</p>
<blockquote><p>Although the 1D-X II shows significant increase in dynamic range at low ISOs in our dynamic range tests, high ISO Raw performance remains <span id="imageComparisonLink2446" class="linkish">fairly similar</span> to its predecessor, falling behind the Nikon D5, and even slightly behind the 42MP Sony a7R II, <span id="imageComparisonLink2447" class="linkish">at very high ISOs</span>. <a href="http://www.dpreview.com/news/8090146652/canon-eos-1d-x-mark-ii-studio-tests/1" target="_blank">See the full studio test</a></p></blockquote>
<p>There will likely be a lot of comparison tests and reviews rolling out in the coming weeks. I haven’t received my EOS-1D X Mark II yet, so I’ll just enjoy reading about it for now. :)</p>

1dx Mark II battery dilemma

Hi,

Does anyone know the performance of the old 1dx battery and the new lp-e19 on the 1dxII? I am cutting a trip very close with when I will be receiving the camera, and I need 3 total batteries. Unfortunately, nobody has the new battery in stock, and may not for my trip. So I am looking at the old battery. I am only shooting video. How will this affect battery life? Anyone test this?

Also, does anyone know if some place rents this battery?
Thanks for your help.

The ludicrously large 1d series

So I borrowed a 1dx from Canon a few weeks ago and enjoyed myself vastly. I also borrowed the 500 f/4 II at the same time, and it was a blast.

In the past, I wondered how people could actually want a camera that large, and I figured that once you had one in the hand that perhaps the benefits of it would make themselves evident.

Well, I loved the frame rate, and I loved the files, but I have to say, I'm still sitting here wondering what Canon put in people's water to make them want to hold what feels like a chemistry text book up to their faces. I was out in the wood and marshes with the beast, so I wasn't able to determine if the combination would - as I suspect - scare small children were I to expose them to it on the street.

Perhaps it's not a question of choice, but rather of how much heft and volume is necessary to house that much electronic stuff, to harden it, to allow for heat dissipation, etc.

I bring this up because I now find myself watching everyone and their brother put up their 1Dx for sale, as they take possession of the new 1dx2. It is sorely tempting to take advantage of the increased supply in the 1dx used market. The price of a decent 1dx appears to be moving below that of a new 5dsr.

I'd sold my 5d3 in order to get maximum $ to put that cash toward the 5d4, but now I'm thinking I could get a 1dx instead. So hear are my questions:

1) Will my perception of the size and heft issue lessen over time?
2) Care to speculate as to IQ comparisons between the non-existent 5d4 and the quite existent 1dx?
3) Will mothers cross the street and put their hands over their children's eyes when I approach with 8 pounds of rig? (Think about that. The weight of a gallon of milk: 8 pounds; and the milk would have a better center of gravity.)
4) This one you need not answer, as I've discovered the answer... Will my wife allow me to carry this rig in her presence when other humans might see us?

Thanks for any discouragement. -tig

Step up ring and hood for 50mm 1.2, does it fit?

Having recently acquired a canon 50mm f1.2 and the missus somehow not minding too much the problem of filters has arisen. All filters I have are 77mm to fit my zooms so I was hoping it'd be possible to use a step-up adapter 72-77mm and still fit the normal lens hood. Does anyone know if it works? The filters I have are all slim Hoya filters

I was hoping to not have to buy more filters as they are after all pretty expensive and the only other lens I could see myself buying with another size thread would be using 67mm filter size.

New 50mm Compact Macro on the Way? [CR1]

HTML:
We’re told that Canon will updating one of it’s niche macro lenses, the 50mm f/2.5 compact macro. As with most lens rumors, no timeline was given for an announcement.</p>
<p>The current 50mm f/2.5 compact macro is very popular with for reproductions and copywork.</p>
<p>We’ve always expected the EF 180mm f/3.5 to be the next macro to get an update.</p>

1DX Mark II purchase in Japan - where??

Help please. Has anyone in the not too distant past made a camera purchase in Japan?

My daughter will be in Tokyo in roughly 3 weeks for a 2 week holiday and is agreeable to bringing home the Mark II if the deal is right since she'd get to use it for 4K video (she's DSLR competent). This would have to end up costing no more than in Canada and I'm guessing that might be a challenge.

So, suggestions please. Also, any experiences with importation issues.

Jack

1DX owners are you upgrading to the 1DX Mark II?

When the mark two was announced I have to admit I wasn't too impressed with the new features mainly the 2 fps increase and 2mp increase and the better AF didn't really scream a reason for me to want to upgrade from my 1DX as I mainly use my 1DX cameras for landscape/adventure photography for it's weather sealing and the 12fps is more then enough for me with the adventure sports I do, but reading the reviews so far and the friends I know who just had theirs come in it really does look impressive with the real world tests.

So are you upgrading? or are you sticking with your 1DX till the mark III?

Also for those of you making money off photography do you see a need to upgrade every time Canon releases a new 1D series camera? I know on the Nikon side a lot of photographers still use the d3s instead of upgrading to the d4, d4s and d5 which struck me as weird but then again I don't know much about Nikon.

1DX2: Dynamic Range

At the risk of starting a thread that will possibly degenerate into name calling and acknowledgement that DxO are the masters of measurement ( :o), I'll expand here on a recent post I made regarding an article in UK magazine, Amateur Photographer.

Written by Bob Newman, a Prof. of Computer Science at the University of Wolverhampton, he talks about the changes in approach taken by Canon and Nikon to their analogue-to-digital converters (ADCs).

I'll paraphrase the salient points:

Previously, Canon's approach resulted in lots of residual noise when using low ISOs compared to Nikon. The reason being that Canon's ADCs were not on the same chip as the sensor. With a limited number of communications channels between them (usually 16 in the top-end bodies), the camera had to process the data very quickly before moving on to the next frame.

There is a trade-off between speed and noise. The read noise would lurk in the shadows and when boosted, would offend the eye (my words, not Bob's).

Nikon had taken the route of placing the ADC on the same chip as the sensor which allowed them to have more of them; 24 on the D4 and thousands in other cameras which used a column-parallel arrangement allowing the ADC(s) to be built into the sensor array. This allows for slower processing and lower read noise.

At high ISO, the implimentation of the ADC is less critical as the boosted signal is much greater than the electrical noise inherent within the circuitry. Therefore Canon's high ISO performance wasn't held back but low ISO had limits to the dynamic range.

Now with the 1DX2, Canon have gone the route of using these column ADCs to get improved low ISO DR whereas Nikon have gone the opposite way to give the user lower DR at low ISO but things improve once you get to high ISO.

So there we have it. The 1DX2 kicks ass at low ISOs but the D5 will take the DR lead at high ISO. Recent examples on the web show Canon's high ISOs are quite smudgie compared to the D5.

Now over to DxO for their take ;)

Cfast Cards that work with 1DX II

I was wondering if anyone has tried any 256gb Cfast cards with the new 1dx II? Looking for mainly 4k video shooting at 60-fps...

I see that lexar makes some, but they say they are for the alexa mini. Do they also work with the 1dxII? Trying to figure out what to buy. I believe canon has only confirmed that the sandisk 128 works. But I need the 256.

Let me know.
Thanks,
Dustin

Some Canon Production Affected by Japan Earthquakes

HTML:
In a statement made to <a href="http://www.amateurphotographer.co.uk/latest/photo-news/canon-makes-statement-kumamoto-earthquakes-impact-74828" target="_blank">Amateur Photographer</a>, Canon has confirmed that the Japanese earthquakes have had some effect on production. While no Canon factories were affected, third party parts suppliers have been.</p>
<blockquote><p>Fortunately, there have been no serious injuries among Canon employees or their families in the region. None of the company’s buildings or facilities have incurred any significant damage and all Canon Group companies in the region are able to operate normally. However, production of some products has halted due to the impact on part supply companies and infrastructure. At the moment the impact to the business is minimal, the future situation is still being assessed.</p></blockquote>
<p>We’re still unsure how much of an impact these issues are going to have on new products coming down the pipeline.</p>
