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.

Just a click of a button can make these types go away:)

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

Let me count my Blue Moons. Canon 24-105 back focus. Sent back to Adorama for second copy. Second copy was spot on. Canon 85/1.8 - ditto. Canon 50/1.8 sent to Canon for calibration. They sent it back after finding and replacing a bad control board. My 70-200/4 IS and 60 macro both require MFA but at least the value is consistant at all focus distances.

My 24-105 and 85 needed to be sent back because the required MFA changed based on subject distance, this is something the Sigma dock would have been able to make up for and I would not have needed to send them back if Canon would built the same controls into their MFA in body system.

lol I'm the same way. 5 of my 13 canon lenses have had focusing issues. 1 of my 5 sigmas has had an issue.

I don't trust canon lenses.

Life was so different years ago - baf. That's before auto focus.
Lol I could be wrong but we just seemed to accept the lens as a tool more back then - and just went out and made photographs...... lol
And computers were supposed to simplify our lives......someone sure git that prediction messed up..... Lol

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.

I don't know if you think you're sounding clever but really it just sounds like you have a poor understanding of what causes AF issues. Canon's AFMA is intended to correct for manufacturing tolerances. The problems Sigmas tend to have are both due to manufacturing tolerance and gross inconsistency.

I have a copy of the previous Sigma 50 that had a gross inconsistency and sent to Sigma for corrections. Came back and now is spot on with focus. I still have 5 more years on my Sigma 7 year warranty to keep my piece of mind.

I had a 70-200 lens that did not seem to focus sharply at around 150-200 range. Sent it into Canon to get fixed, they returned back saying they found no issues. Tried using it and still had problems. Sent it in again with photos and this time they said they made some adjustments. Tried it out, better but not as sharp as I think it should be. Third time to Canon and finally got a new lens from them.

Have to say the Sigma experience was much more pleasant.

I hope you are not trying to insinuate that inconsistency issues are limited to Sigmas:

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

The Canon 50mm 1.2 has a similarly bad reputation to the Sigma 50mm 1.4 in terms of focus reliability. However, note that 50mm planar lenses have focus breathing issues, that is the focus point changes with the aperture setting. Which adds a lot of difficulty as the camera is always focusing at f/1.4.

Also note that Canon has changed how autofocus works with the 6D and 5D Mark III, there's now a closed loop system. The latest lenses since about 2012 like the 24-70mm II 2.8 have a rotation sensor built into the lens. So the lens focuses and reports back to the camera it's focus position. It didn't used to work like this it used to be a fire and forget system.

50L could've been one of Canon's finest IMHO. I just love the rendering of that lens. I just wish it was a bit more consistent in terms of focusing. Here's hoping the new Sigma is a marked improvement.

My first of the new Sigma lenses is a 120-300 Sports, and if this is the standard of all their newer releases, then I will have faith in the 50. To be honest, I returned 3 Sig 50's as all 3 of them were lemons on my 5D3, and eventually settled on the Sig 85 which is awesome. But the 120-300 Sports is just amazing.

The inconsistency of its AF is actually a function of the design that allows it to render the way it does. The lack of a floating element allows leaves a lot of uncorrected spherical aberrations that create that beautiful bokeh and overall dreamy quality, but it wrecks havoc on AF systems.

Same goes for the old Sigma 50m 1.4! Which had fantastic rendering and brilliant bokeh, and was generally on par with the canon 50L... but the focus issues. It wasn't even micro-adjustable because it is inconsistent depending on the focus distance.

It appears neither Canon or Sigma could get a 50mm Planar to work right with AF... Bring on the retrofocal 50mm!

The 35A was $899 when introduced I believe.

As nice as this lens is, I think I'm going to pass. Too rich for my blood. For now at least. Maybe when prices come down.
