EOS Bodies / Re: Canon 6D True High ISO King?
« on: August 24, 2014, 07:34:42 AM »
How does the EG-S screen for the 6D exactly work? Could you also use it to manually focus on a subject located at about one third from the left or right side in the viewfinder? Or does it only work for subjects in the center of the viewfinder?

It works across the whole screen, but once you move away from the broad centre, the lens you are using will dictate how effective it is as many fast prime's resolution drops away towards the edges of the frame when fully open, and as all cameras now have 'open aperture metering' you are viewing through the lens at its least efficient, resolution wise.

I find the major benefit of the 's' screens is seeing the actual dof. I use them but I still use AF too.

@pablo,

I don't really see when you're coming from with this issue of AF video on the dslrs. Surely the vast, vast majority of these cameras are sold to the casual video user, and they want AF, preferably AF that actually works. Many have found that for 'home movies' the dslr is wholly inferior to a handycam; the DPAF goes some way to helping with this. In fact I would say it has been welcomed by the buying public. The development of the video function as part of a dslr is of no relevance to the likes of BBC or ITN surely ?

I also got my 5DII when it was first released and have never had an issue. Neither have I ever updated the firmware - 'cos I never do  ;)

The 5DII must be remembered as one of the best sorted cameras right from its inception; not a good example to use !

HEHE.. that makes me chuckle. :P


Bet I was chuckling a lot louder when I read your complaints of noise in skies shot on the 5DII.

I stand my my earlier remark; the mkII was ( and still is) a well sorted camera.

Imagine doing a fast lens change with the 85 f1.2  :o

Could easily end up as  :'(

I use BBF so never have to switch lens to MF. Even for hyper focus I aim at an appropriate target and use BBF, so this includes landscape. I use the 's' screen and have played about with using manual focus against AF in critical conditions, and more often than not the AF gets it better than I can, but that's probably just me. Also if you're going to try to manual focus as an improvement in accuracy you're going to have to use L lenses in order to have the appropriate control over the focus ring.

Lenses / Re: Canon EF24-105mm f4 IS USM time for a refresh?
« on: August 22, 2014, 04:30:42 AM »
So what needs fixing?

* distortion at the wide end  - use the 16-35 f/4L
* softness at the long end - use the 70-300L
* lack of IQ in the middle - 24-70 f/4

So instead of fixing the 24-105 and making it better, Canon effectively encourage you to sell it and buy three other lenses instead, resulting in a net of two new lens sales to replace one lens.

And given that Sigma failed to deliver a substantially better lens with a bigger construction, what motivation is there for Canon to fix the current model?

*distortion at the wide end: think of it as a 28-105 and you won't go far wrong
*softness at the long end: improve your technique
*lack of IQ in the middle: give up photography and take up embroidery.

Lenses / Re: New Canon L Primes, but Not Until 2015 [CR2)
« on: August 21, 2014, 04:23:12 PM »
So how does that explain the fact that Sigma released a 50/1.4 under $1000 that is better than any Canon 50mm prime out there? ... The bottom line is that Canon makes crappy 50mm primes.  There is no escaping that.

Because Canon's first priority is professionals who depend their livelihood on the unmatched portrait performance of the 50mm f/1.2L.

As time goes on I'm having more respect for the 50 f1.4. It's a lens that is capable of producing images that boast a very expensive signature, even at f1.6 if you get the subject, distance and lighting right. Certainly not 'crappy', unless of course, you happen to be a 'crappy' photographer, then maybe an Otus is 'crappy' too.

Does anyone here remember how long it took Canon to address issues with the 5D Mark II? It definitely wasn't this quick!

Does anyone remember issues with the 5DII ? Talk about clutching at straws.

I received on of the first 5D MK II's about November 27, and a week or so later, on December 8, reports of a issue from black spots appearing on bright highlights when people shot Christmas lights.  NR normally made them go away, so many did not see them.  I had to review my shots to find one that had them.

On December 15, about two weeks after the first Camera deliveries, Canon announced that they were looking at the issue.  Canon modified the firmware to eliminate them.  On January 9, three weeks later, Canon issues a firmware update to fix them.

So, it took ~ a whole month from initial reports to verify the issue, develop a firmware update, test it and release it.

How many D810 users will have their camera fixed in a month?

I also got my 5DII when it was first released and have never had an issue. Neither have I ever updated the firmware - 'cos I never do  ;)

The 24 -105 was introduced with the original 5D and that combination made a budget wedding photographers 'kit'. The 105mm focal length went someway to compensate for the dof of an f4 lens so you can still produce some nice shallow dof portraits. I would suggest that for an event like a wedding the 24-105 is a much better lens to use than the 24-70 F4 IS, whereas if you are looking for a sharp landscape lens to use instead of primes, the latter is definitely better - assuming you get one that has been tuned up correctly.

I don't think we will see a mark II because, as has been pointed out, to improve the IQ over that range the increase in cost is going to be prohibitive. Also the mark I is still such a good lens for weddings ! I don't do many, but on one recently I used the 24-105 much of the time, and I was really pleased with the results.

I've always said the image quality from this latest generation of Canon FF cameras is superb, whether high or low ISO. Posts from 'professionals' who criticise the IQ in non demanding situations is a good way of raising blood pressure.

Nikon is seriously doomed.

Wouldn't be good for any of us if they were.

I can't help wondering if Sony might buy Nikon from Mitsubishi.

The moisture obviously is very quick to get in, but takes a lot of time to get out.[/i]

That's the worst part of inadequate sealing. There is an answer though; get an original 5D. The moisture is quick to get in but comes out just as easily  ;)

Oh dear there's going to be terrible anguish, spitting feathers and general sabre rattling if the 7DII doesn't have some sensor fabrication advance similar to the Exmor. But you know I'm not really sure how much pressure there is on Canon to catch up on this. It would seem that 99% of Canon users (generically speaking) are not bothered about that particular aspect of the sensor, including many well respected professionals; certainly judging by sales there are many other features which the buying public seem to want. Certainly the amount of people using variable ISO now surprises me, but on the other hand given the performance of a camera such as the 6D I suppose that shouldn't be surprising. And when using variable ISO who wants their DR to drop by a stop or two between ISO 100 and 800 ?

That is because those who are bothered by it will be/are moving to other manufacturers. If Canon are fine with bleeding off their market base, then sure, they won't care. If all depends on if the assumption that Canon are cool with losing market share to more progressive manufacturers is true or not.

I suspect they are not cool with that happening.

You skipped a step.  No, Canon doesn't want to lose market share.  But...you are assuming they are, in fact, losing market share.  Where is your evidence to support that assumption?   It seems equally if not more likely that those who are bothered by a ~2-stops less low ISO DR and switched from Canon to Nikon are outnumbered by those Nikon users hoping for the true replacement to the D700 that never came, and so bought a 5DIII instead. 

As for 'more progressive manufacturers', your definition of progressive is almost as biased as DxO's Scores.  DPAF...not progressive?  Fluorite elements in supertele lenses, you'd think a progressive company like Nikon would have used them decades ago like Canon did...instead Nikon called them too fragile, only now they're touting the benefits of fluorite in their newest supertele lenses.  Limiting the definitions of 'innovative' and 'progressive' to mean achieving more low ISO DR is typical of the biased DRivel posted by the crew of CR Forum DRones.

In the course of my work I come across a lot of people with cameras, and not many of those are true professionals. Some are just happy snappers, or tourists, or teenagers aspiring to a better camera. The odd one is a highly successful pro who buys £250,000 yachts with loose change ( seriously). ( zigzagzoe's got a long way to go to catch up).

Often these people will chat to me and I'll ask them why they chose Nikon, or Canon or Sony ( 'cos it's always one of these). I've never had one single person say they chose Nikon or Sony because of the extra DR that the sensor offers, or that it has more latitude and can lift shadows by five stops without seeing ugly noise. Not one. Ever.

So although those factors are the number one priority for some, generally very vocal people, and they will move away from Canon, I would suggest they are just a drop in the ocean compared with everyone else. So although I read on CR that Canon is using the same sensor fabrication that Noah had on his Ark, I'm really not sure that Canon are going to see this as a really high priority, especially given the fact that their sales are not declining in relation to Sonikon.

People do have issues with things like trying to focus in movie mode with a dslr for instance, and Canon have done something about that. I've been surprised by the number of 70Ds I've seen given that the camera hasn't been out that long. I would say that the vast amount of casual users are going to appreciate that more than lifting underexposed areas by five stops, and they are the people who are buying most of the cameras.

So what I'm coming round to say is I don't think the 7DII will have a radically different sensor fabrication, and I anticipate the howls of derision that are going to fill these pages from the usual sources.

It is amazing how responsive a company can become once a big market flexes its muscles, Nikon and China, GM and the USA.

I'm on the fence with this one.  Dust with the D600 100% should have been caught in evaluation period before launch.  But finding an issue that only shows up in crop mode + long exposures might be more of the weird lightning bolt of an issue you don't find until you release it to the masses.

- A


I'm not, long exposures and crop mode should be covered in even the most basic field trial testing protocols, what the hell are these guys doing? Not saying Canon is often any better, but come on, this is basic stuff. It might not affect many users actual images, but should easily be noticed with an efficient testing strategy.

I would think it's been rushed to market. Quite a few years ago we sold our digital imaging business to Mitsubishi -the owners of Nikon -  (and then ended up buying it back) so I know how these guys work. Nikon will be under a lot of pressure to increase margins, profitability per unit, farming production out to cheaper countries etc etc. I have no way of knowing but I would guess that a D810 costs less to produce than a 5DIII. Probably not in the D4s / 1Dx range. Seems to me they are trying to get the D8xx into a guise that will increase its appeal. Adding sRaw is a good start. I just cannot believe that Nikon introduced a 36mp camera without a smaller raw option.

Or perhaps it's intentional because the D820 will be out by Christmas.
