My experience is the same: my 5DII focuses better than my 5D. Tweaked algorithms? Faster CPU? Whatever, I can use the outer AF points with my 50 1.2L whereas they were very iffy with the 5D.

The 5D2 does have a focus problem: except for the center point (and its associated assist points when in servo mode) the AF points are not very good in low-light, low-contrast situations. This renders the camera much less useful than it could have (should have!) been. The 40D and 50D have cross-type sensors in all nine locations. The 5D2 deserves no less. For the price, it ought to have more than nine AF points, all of them cross-type.

Like Chris Miller, I photograph musicians in low-light. The 5D2 sensor is great for this. The AF system, well... Let's just say it's inconsistent, and thus unreliable. Last weekend I had the opportunity to photograph the same jazz group, in the same dimly lit venue, two nights in a row. Friday night I used the 5D2 and a batch of fast primes (we're talking 1/50th at f/2, iso 3200 here). Saturday night I took a D700 and some fast primes instead. The Nikon gave me a much higher keeper rate, and the AF point layout allowed me to compose the photos much more to my liking. This was the first time I'd touched a Nikon in over 15 years; I was not very familiar with the camera. Nevertheless, it has an AF system that makes it much more useful for all-around work. I'd be much happier with 12 in-focus megapixels than 21 out-of-focus megapixels. When the 5D2 does nail the focus, the files are usually superb. IF the camera nails the focus.

Focus-recompose is difficult to impossible when shooting wide open and/or when the subject is in any sort of motion. For those of you reporting great results, what are you doing? Are you using mostly center point? Are you working in low light? Are your subjects in any sort of motion (when using the outer points?). I've gotten surprisingly good series of photos using servo and an outer point on the face of a musician, only to have the player at the next mic step up for a solo and the camera misfocus on him 90% of the time. This is extremely frustrating. We shouldn't have to spend $6000 to get a full frame Canon body with reliable focus off the center point.

Slightly off-topic, for Chris: have you found the 7D to be usable at iso 3200 or higher? You say you're going to pick one up to use alongside the 1D4. If the 7D is playing in the same ballpark as the 1D3 and 5D2 for image quality at high iso's, I'd want one myself.

Wow. Focusing accurately on a 50 1.2 with outer points! That is pretty amazing for any camera.

My 2 cents is the 5DMK2 is right up there with any camera at center focus. The outer points have issues in low light. I don't shoot that much in low light so it's not a big deal for me. If someone does shot a lot in low light than it is an issue.

No problems here either. My 5DII excels in low light with the center AF point, even my old Sigma 30/1.4 nails focus in very low light (yes, of course there's major vignetting) at ISO 3200 and f/1.4 consistently.

It's a well-known fact that the 5DII outer AF points aren't stellar, but I doubt any DSLR can beat the 5DII center point in low light.

C'mon folks not everyone is being a troll and there have been issues. Putting fingers in ears and singing la la la wont help.
In answer to the OP - yes I had issues and it took two trips to Canon to get them resolved and that only AFTER I sent in JPG photos showing the focus issues. I took a series of shots from tripod showing focus on 10 shots using the AF system. Each shot reset to min focus distance. then 10 shots using Live View and zoomed focus - same drill. the AF shots were all over the map - the LV shots were all dead on. Canon admitted to recalibrating the AF assembly. Now my 5D MkII is dead on and I couldn't be happier - but there were indeed issues and everyone who has brought them up has been shouted down. Jeez - some folks here sound like fan boyz.

This is definitely a legitimate post, as I can affirm since I just got my camera back for the second time having Canon "adjust" the focus, to no avail. In my experience the 5d ii basically has a one point focusing system, and that point is decent but not stellar. The infuriating thing is that it is wildly inconsistent, even with the center point--it can hit one shot dead on, and then the very next shot, even on the same subject, the thing can't find water in the ocean. Yes, I understand and agree that the photographer needs to be responsible for focus--but as has been previously noted, this is not always possible in some situations, there are circumstances under which you must work quickly, and at those times the camera must be reliable. In my estimation, the 5d ii is not reliable at those times.

I became so perplexed by the focusing inconsistencies that I took all the lenses that I normally use and tested them on my film camera, an EOS 3 (which has quite a reliable focusing system). According to those tests, those lenses all are capable of focusing flawlessly, so the problem really is with my 5d ii.

Unfortunately the microadjustment control is not really a solution because the camera itself is so inconsistent--the amount of front or back focusing varies from shot to shot, and in some cases it is dead on, so the microadjustments provide no solution.

I was recently photographing for an article I was writing in South America; it was at a religious festival and I did not have time to baby the camera, and I wound up putting it in the bag and using the film camera instead--but I certainly didn't intend to pay $2700 for a camera that was buried in my bag while I a used EOS 3 I bought off of Craig's List for $50 did the real work.

I am kind of disgusted by the situation with the focus problems on that camera. I wish I had gone with Nikon or Sony instead. Still, I must admit the output of the 5d ii is sensational, but for me it is mostly a camera for situations in which you can be very deliberate, or focus it in live view on a tripod. In those situations it is superb. Shame on Canon for putting out a $2700 camera with the rinky dink focusing system they have on their entry level models. Even the 40d and 50d have better focusing systems. I think it is appalling that they want $2700 for a camera with a professional output, but if you further want a professional focusing system, you have to come up with a few thousand more, despite the fact they developed great focusing technology many, many years ago (as my EOS 3 consistently demonstrates).

As for customer service fixing the problem, they apparently have no interest. I live in Los Angeles, and the center is in Irvine so I take it in personally. I went down there last week, explained the situation thoroughly and asked them to look into it again. So I drop off the camera. and I got a call three hours later--yes, three hours--telling me my camera was fixed and ready to be picked up. Three hours? So in three hours they have gotten the camera to a tech, who has inspected it, tested it out, and done the necessary repairs? Umm . . . that somehow seemed unlikely, but that is what they claimed. I went down and picked up my camera, and not surprisingly it is exactly the same as it was before. Gee, next time maybe they will even keep it for a day or two, to make it at least seem like they are actually looking at it.

"My 5D Mark II has a focus problem" = legitimate post.


"Since the Cann 5dII's focus issues are pretty well known..."
= troll post.



Sorry... but FWIW neither of my 5D Mark II's has had any focusing problems, let alone the "wel known" ones, whatever those are...

I must admit, I have actually experienced several times where in low light situations, using one of the outer points, the AF does tend to hunt for a while. (used both a 35L and 135L) Mostly an annoyance, or am I just not wanting to admit it is a problem?

I still shoot a Nikonos RS underwater film camera (1992), one of the first autofocus cameras. It is difficult to get more primitive than this. I ALWAYS give it a high contrast edge to focus on. I can't say I've ever had any problems with AF cameras, even this old Nikonos, if you give it an edge to focus on!

I keep reading this. I always use my 5D in center point only, and usually in bright light. So I tested 5D1 (haven't tested the 5DII yet). I used a 50mm f1.4 , famous for poor low light focus. I focused on a rectangular picture frame, high contrast, at night with only a 14 watt fluorescent bulb. I believe this is EV 5, very low light. The 5D1 locked instantly with the outer points on one edge of the frame, and hunted on the edge at 90 degrees. So the problem is not low light or poor 50mm lens. It is the lack of a cross sensor. If you rotate that outer sensor point about 45 degrees, it locks very quickly. A little user experience and knowledge can do wonders for even "inferior AF sysems"!

But it's still an inferior AF system. If your subject is a little more animate than a rectangular picture frame, the technique of rotating the camera is useless. Try photographing a musician on stage with an outer focusing point on the 5DII (low light, close to wide open aperture so very little depth of field, subject moving a little while playing an instrument) and you'll be in a for a frustrating experience. Sometimes it works, sometimes it doesn't. On a $2700 camera, in 2009, there's no excuse for that. How much could it have cost to make all the AF sensors cross-type?

And plenty of folks whine the outer AF point on the 7D are undependable, and they're cross sensors, so that may not solve your problem. I suppose I grew with such crappy gear I'm continually amazed at how good 5DII AF is! I recall my Elan 7E, EOS 3, 1N, 10D & 20D were really a crapshoot with the outer points compared to the 5DII. Actually I shoot musicians performing all the time with my 5DII and it rarely misses. However, I'm shooting on stages with pro lighting, not smoky bars with cheap lighting trees so that may have something to do with it.

I agree with Mr. Levitt here--there is no excuse for this shoddy of an AF system on a $2700 camera. Yes, of course, cross sensors can miss wildly also. For those of you who are not having problems with the AF system, I give you my whole-hearted congratulations. Unfortunately the rest of us who would like a slightly better success rate are left to wonder why such a ballyhooed camera did not warrant at least a slightly better system, especially since Canon has the technology at its disposal, and had already installed it on other cameras. As I stated previously, the output from the 5dii can be sensational, but had I known I was spending $2700 for a camera that would turn out to have a limited application for me (i.e., not reliable for active situations when AF is necessary), I would have certainly bought another manufacturer's product. Honestly, the impression I have increasingly gotten is that Canon does not have much respect for the customer's pocketbook.

I have the microadjustment on my 35L at plus 20, and it still isn't exactly right, but I can't adjust it any further. It's not the lens, it focuses dead on with my film body, it's the 5dii which just doesn't want to focus it.

There is nothing wrong with the 5d2 AF. you only need to know how it reacts to specific situations, once you master that it becomes 2nd nature.
