Bought a 5D3 and a Sigma 50 yesterday, and after a year with te Sigma 30 and no micro adjust on my 550D, I am loving the feature on the 5D.

I have only had a small play around with it though, and amazingly the Sigma needed +20 to get the focus close to spot on - I even think it could do with a little more.

Should I be keeping it as is with MA+20? Or should I be I unsatisfied and get Sigma to adjust the lens for me?

What is the process - do they need to keep my camera with the lens while they repair it? What's the downside of keeping it on MA? Is there any downside?

I would send it back for adjustment. Sigma was fast. +20 too much for my liking. Plus, if you sell the lens, you have taken care of the problem.

Exactly what I was thinking, 20 is a LOT. Wondering whether my chances would be better getting a warranty repair or a replacement lens?

If you purchased from dealer like Adorama or B&H, they will exchange it with minimal issues ( usually). As long as it is in the return period. Otherwise, Sigma it

I have Canon 5dm3 and Sigma 50mm 1.4 and i have the same problem.

I used lens about +20MA and it is not enough. Some of my friends calibrated their Sigma lenses. In my country, sigma is very efficient about this type of problem. They calibrate lenses without paying. But they need lens and also body to calibrate! So i should send both to Sigma.

I cant use cargo because of body or lens damage. I will go to service myself and that is 500km far away from my city. So that is why i am waiting for.

I'm Australian, no no BH or Adorama here - but I bought it from Michael's here in Melbourne, so a return would be fine I am sure. Thing is though, I wonder if I would be swapping for another lemon?

Yes I think +21 or +22 would be perfect for mine, not quite perfect at +20.

Do you know how long roughly they need it for?

I don't want to leave my 5D3 with Sigma repair (CRKennedy here in Melb) but if it means the lens comes back perfect, I guess I would. Will call them tomorrow.

In your situation I would call them and see what they can do for you, being so far away.

I went through 3 copies of the sigmalux all needing +20. On my 4th copy, it only needed +3 so I kept that one.

When I had a Sigma 30 (on my T2i so no MFA) I went through 3 copies that front focused. I sent it in to Sigma without my body. It came back after about a week perfectly calibrated.

before you go to that trouble, what focal distance are you checking the focus and micro adjusting at? Over the past couple of years I have had SEVEN Sigma 50's and the only consistent thing I've seen on all is that the degree of focus shift changes with distance (and the aperture setting with a big shift around 1.8 to 2.2 typical).

This is why micro-adjust is only ever an imperfect fix for these lenses. You might be spot on at one focus distance (or aperture setting) and way out at another. Key is that you do your micro-adjust at the typical distance and aperture setting you'd be working - for me 1 to 1.5m and f2 to f2.5. Check your microadjust at your preferred distance and aperture - perhaps it's less than 20 and so things not so bad?

How old is your lens, Kobeson?

I'd be trying to swap it for one that works = test in store, with several shots at near and far focal distances.

I took my lens back to CR Kennedy 4 times here in Sydney (along with my old 7D), and ended up getting it replaced after going through the calibration song and dance for nearly a year.

I dont know how long they keep the lens and body. This week i will call them. If they calibrate my lens without my body (by using their body) and maybe i will need MA less than +20 with my body. So that is another solution. If it is possible, perhaps i can cargo only my lens.

i bought a sigma 50 1.4 at close distance it needed more then +20 MA, at longer distance it needed about -4.

really horrible lens, changing from +20 to -4 MA depending on distance is not a good practice, returned the lens, and this was my third sigma 50 1.4, I won't bother with this lens again, maybe once Sigma released fixed Mark II i might try it again.

I want to buy a macro in a few months. I decided to buy Canon 180mm L or Sigma 150mm OS.

If Sigma has problems like this, i never want to buy anything.

Do you know if Sigma 150mm 2.8 OS macro has problem like this? (+20MA is not enough)

send it to sigma... Mine came back perfect.

Never had issues with my other Sigma lens... the 10-20. Then again focus isn't too difficult to nail at 10mm and f4

I would say +20 send it back. I am currently on my second copy of the Sigma 50 because of focusing issues with the first one.
