Sigma have done a pretty amazing thing. They have actualy convinced many users that it's not their responcibility to supply lenses that focus correctly. As well as shifting the responsibility they are actualy going to make money from the fact too.

Nice work Sigma.

I agree fully. I have owned about 12 Canon lenses over the last decade, and every single one has focused accurately out of the box.

And you have assumed that I "hate Sigma" simply because I'm critical of their thinking regarding the dock. I'm on occasion critical of my wives cooking. It does not mean I "hate" her.

no i assume you hate sigma based on your tone and your general attitude.

you can freely send a lens back to sigma if you want. you may also purchase the dock and do it yourself. you pretend that you have to buy the dock to sort out any focus issues, this is 100% false.

furthermore, the dock allows you to calibrate based on 3 distances. This allows people who really want to get it perfect to do so instead of using 1 value for lens correction in their camera.

take your average enthusiast on this site, give them a canon lens, i can almost guarantee they will assume it's 100% unless multiple shots prove otherwise.

give them a sigma and I bet the first thing they do is go out and try to produce focus problems.

Yep, canon lenses have problems...Once in a blue moon.

We must get blue moons quite often then. Canon AF problems are not as uncommon as you seem to think. A quick search of this forum will show you that.

MattD wrote in post #16813220 (external link)
They have so many problems that out of the 20 or so canon lenses Ive used or owned i yet had to send any of them to be calibrated. Not one.

Sigma on the other hand. Currently on my 3rd 50mm 1.4. All have had issues. Had the 70-200 too, that had issues

I guess from your experience with 20 lenses that we can extrapolate to all the millions of lenses Canon have produced, eh?

Out of all my lenses (a nice mix of Canons and Sigmas), the only ones which have had any kind of problem at all were the following:
Canon 24-105, faulty aperture/IS
Canon 50/1.4, inconsistent AF
Canon 50/1.8, inconsistent AF

I've had/used a similar amount of lenses as you, so where does that leave us?

MattD wrote in post #16813220 (external link)
IF there is a problem Id 1st ask why im required to spend additional cash on a product to fix it myself?

Read my post. You aren't required to do that. You have the option to do that. If you don't want to do that, you can send it off to be fixed under warranty just like you would do with a Canon lens.

What you should be asking is why you would want to do that.

The answer would be: the ability to fix focus issues on lenses without having to send them in and be without the lens for x days/weeks, the ability to customise certain lenses for greater speed vs greater accuracy, the ability to update firmware.

i think you accidently clicked on a sigma thread about sigma lens when you are a sigma hater. please use the back button on your browser to return to the main forums and select a canon branded lens to discuss.

I lol'ed :)

There will always be a vocal minority that can't stand third party lenses, but will continue these discussions.

If you you can't handle third party, stick with OEM.

There are drawbacks of third party lenses, and if your expecting perfection, rely on OEM.

Even sticking to OEM won't guarantee perfection ;)

Wow. Ignorance is bliss. You better read more about how phase detect autofocus works and as well as manufacturing tolerances of cameras and lens before you make a sweeping statement like this one.

There isn't anything sensitive about my post. It's about tolerance for third party lenses. Let's not pretend you have any tolerance for them to start with. I'm perfectly fine with it.

Classic.

Not so much sensitive as tired of people like you providing nothing to conversations and trying to derail them with trollish comments.

in a discussion about a new 50mm lens, you provide what is essentially "i can't believe sigma makes you buy the dock for their crappy lenses instead of shipping them in working order like canon does."

please just go away.

If it is announced on the 11th as rumoured then it shouldn't be too long till a proper review! I remember reading it has a floating element which is meant to help the AF consistency so I expect to hear about it :P

Considering how expensive the Zeiss is it ought to be better! LOL.

Not sure if you realized I was being sarcastic, or that the Otus is an MF lens...

My comment was in reply to a comment about the dock. Sorry it wasn't all sun shine and light.


I also never said anything like "crappy" lenses either. If you had bothered to look at my post history you would know my opinion of sigma lenses.

Yeh, Canon is soooo good with AF it just put the ability to tune AF into their cameras so that people who purchase a Sigma could tune it on their Canon camera. They added this feature out of the goodness of their heart just to help out Sigma.

I use all sorts of lenses and every single lens I have purchased that has AF abilities needed some micro adjustments. Every single one, some more than others, some less...but not one was perfect. If you got 10 Canon lenses that were perfect ( at least by your standards ) then I suggest you go out and buy a lottery ticket.

if you expecting perfection...then i'd say you are SOL. OEM lenses are sure not perfection...not in a long shot.
