Lenses / Re: 24-70/4 MFT charts

I have a question, what is a MFT chart?


It tells you about sharpness, contrast reproduction and bokeh quality at wide open and (for Canon) @f8. It doesn't tell you about vignetting, distortion, flare or onion bokeh.

This is what you want to read (and then read again and again trying to remember it :-p): http://www.luminous-landscape.com/tutorials/understanding-series/understanding-mtf.shtml

EOS Bodies - For Stills / Re: 60D Microfocus Adjustment on FoCal

Reikan is looking into the possibility that the 60D's lacking of MFA is only in the UI software.

I wouldn't be surprised - the ui was/is in the 50d and 5d2, the only thing Canon most likely did is set a preprocessor macro flag before compiling the firmware: #define DUMB_SUCKERS_AFMA_UI_DISABLE 1

You can write arbitrary Canon settings with Magic Lantern - the problem just is that w/o documentation it's hard to figure out where the memory addresses are, and if you're getting it wrong the camera is bricked. But if the afma functionality is there, it should be possible to use it after much trial & error.

When can I hope for the next rebate program? Nothing before Xmas? right after?

At least in the European rebate programs Canon in just discounting older and standard lenses and some tele zooms - I wouldn't hope for an official discount on this one for one or even two years to come I'm afraid to say. More likely they'll do a kit with the 5d3 sooner or later, I remember it's been seen in Australia.

looking at the MTF from the canon.. why do you think the sigma is worse?

Argh, sorry, you're of course correct - I mixed up the two Canon lines comparing them to the Sigma :-p ... the Sigma has the "better" chart (or more aggressive marketing division), though the line indeed goes down after 2/3 of the frame.

can someon explain what he reads out of the MTF chart?

Sigma obviously only shows the lens "wide open" results, Canon also has the f8 graphs (see attachment).

Having read http://www.luminous-landscape.com/tutorials/understanding-series/understanding-mtf.shtml and http://www.sigmaphoto.com/pu-mtf-chart-guide ...

... [edit] I'd say leave I should only interpret mtf charts when I'm fully awake :-p

But charts are just charts, doesn't mean much - the charts predicted the new 24-70/2.8 to be "THE" lens, but in real life of course it isn't and no mtf chart tells you about distortion, flare or onion bokeh.

I hope 3rd party products like this moderates how Canon prices future lenses like the 35/1.4 II.

It'll influence Canon's pricing alright - by making the L glass even more expensive because people are usually thinking "it's mighty expensive, it has to be stellar".

If the new Canon 35/2IS would be a couple of hundred $$$ more expensive they might even sell more, now that the price is comparable to the Sigma 35/1.4 people will actually compare the lenses on equal footing - and the Canon without the red ring might not necessarily come out on top.

I bet the USB port was included to reduce the number of warranty service requests. The Sigma 50mm 1.4 has some of the worst focus shift I have ever seen.

And surely it's there in case Canon (or another manufacturer) decides to modify the upcoming firmware updates or camera bodies so that 3rd party lenses miraculously show strange behaviors :-p

The lens looks really attractive, but if buying 3rd party lenses for Canon - why use Canon at all since they are behind in sensor tech and camera body price? That's what lets me still hope for an updates Canon 50mm prime, though the Sigma 50mm is good and has a good price, too.

Making a normal zoom, especially a fast normal zoom with IS is the greatest challenge their is.

I was under the impression Canon didn't choose the 24-70/2.8IS prototype because of weight and bulk issues, and not because it's very difficult to add IS to any lens?

Why in hell would I care about lens size over usability?

The newer IS system and near-macro capabilty is a big usability plus, many people might want to trade in the 70-105 zoom range if they have a 70- tele zoom anyway (and most will sooner or later). So as with the 6d, this zoom is ideal for traveling, maybe in combination with a physically short 70-300L

It's just and again the price tag that clouds the sky and the assumption that Canon does not want to give people the choice but wants to engineer them into buying more expensive gear than they'd like. And imho it's still the aftermath of the 5d3 price shock, Canon simply being greedy and thus alienating their former loyal customers.

2605
it's possible Canon does not expect to move a huge volume of them (unlike, say, the 24-105/4L IS or 17-40/4L), and has priced it higher to compensate.

Possible, it's a pity we don't know the manufacturing cost curve in comparison to units produced. It is obvious lenses like a 600L will be expensive because of low volume, but I'd expect the costs for (kit?) lenses like the 24-70/4 to drop drastically even if they don't reach the #1 sales position.

And Canon is known to try to get away with as much as they can grab I'm afraid to say looking at the 5d3 price - I don't believe the manufacturing cost of the 1dx af system and a modified (silent) shutter explains the initial $3500 price tag.

I know their sales numbers on aggregate haven't been stellar, but in general, the company wouldn't be here very long if it couldn't course correct as needed.

A large enterprise like Canon doesn't just disappear because they can soften the fall and distribute profits and losses between divisions. They can survive quite a long time without good sales if their shares don't plummet and there's a hostile takeover. And Canon just has the advantage of a user base that is tied to their system, so they are quite safe unless they completely screw up.

That's why it takes them so long to correct a flawed strategy in one segment like dlsr - in a smaller company the execs would get fired much faster enabling changes. But if they are really persistent to ignore reality they'll indeed go the way of Kodak and all other long-gone electronics companies.

For many years, it has been argued that people who buy Macs, and more recently, iPhones, are paying more to get less.  So maybe it's the same silent majority that has made Apple the largest company in the world...

"Two mouse buttons confuse me" Mac-users aside, iPhones offer not less, but more for more money: fast hardware, more apps, a fine-tuned integrated and *working* ecosystem, better usability, better os upgrades (unlike Android). And unlike Canon Apple makes their customers go ecstatic with each and every product, while Canon just manages to make most people I know shake their heads in disbelief.

But the main difference is: Apple is way more innovative while Canon is the most conservative company I can imagine, the current Canon execs would get fired @Apple in no time. The only strategy I can see from Canon atm is to make people believe "it's expensive, it has to be stellar".

2608
Canon is listening to customers, they're just not listening to the vocal minority ???
The thing is, the people on the forum are not, generally speaking, Canon's major target audience.

I agree that this forum is not a representation of Canon's whole customer base - well, maybe the enthusiast "L only" side.

But what silent majority is supposed to be Canon's target audience that wants to pay more to get less? Even newbies to dlsr won't say "what? built-in gps? I'll take two!" when the Nikon body next to it has more mp and a lower price tag.

so will they offer a choice of two lenses when the 24-70 f4 is released? How will that work then since the 24-105 kit will be much cheaper?

The 24-105 kits will be just there as long as they've sold all old lenses and the new 24-70 are in volume production.

And the 6d+24-70/4 kit might not be more expensive, the price for the lens alone is likely to be overpriced because Canon wants to make the kit appear more discounted and attractive - otherwise the 6d is sure to loose big time against the d600.

I can see them falling into third place behind Nikon and Sony in a couple of years.

As soon as their strategy appears even non-working to Canon shareholders, they'll come around and fire their executives and revise their pricing. The only ones sure to loose are the customers paying the current high prices until Canon realizes this won't work forever.

Congratulations! At the MSRP of 1500$ for the 24-70 f/4L IS. This lens is now

DOA.

I agree if purchased separately, but the theory was all along that this price will be just a marketing joke to be able to sell heavily "discounted" kits with the 6d making the new camera body more attractive.
