Sigma 50mm f/1.4 EX DG HSM -SIGMALUX-

You shouldn't have to 'micro-adjust' this lens (or any lens for that matter).
Send it in!

Ben, your lens is FF by a tad... not as bad compared to mine before. That lady's nose would have been sharp instead. lol.

Agreed! Dunno if you saw my prior comments... 100% spot on, 1D series, 40D and two 5D bodies. I got my 5D2 and had to dial in 10 microfocus (can't remember if it was + or -)

yeah, those shots are all PRE adjustment. It's NOW spot on. I'll have to test it on my wife's XSi to see how it does there. If it's ALSO FFing there, I'll send it in I guess, but if not I'll let the camera that can adjust adjust, and the one that can't be good...

Like the guy said in the shop I was testing it in:

It's a VERY common problem according to this dude (and Kinefoto is a very good/popular shop in Hong Kong).

This is TERRIBLE. I don't care HOW "good" a lens is, if you have to send it in to get fixed right after buying it, what the heck is the point?!

I'd rather save and get a 50L just to boycott Sigma's terrible QQ issue with this lens.

Sure you can use AF micro adjust, but I want to be able to get it reasonably sharp on my 5D, not have to bring out my 5Dmkii with me all the time.

Shame Sigma, shame.

Well, I really wanted a 35L anyway

The 50L is not that much better and has its own quirks as well (the reason why I got a sig 50 as well). At least these 'issues' with the sig is correctable. Turn around for the repair was 4 days the first time and 1 hour the second (repair center is 5mins away from where I work). Like I said, worth the effort.

Yeah, but the "effort" shouldn't be necessary right?! If most people have to repair it to get it to focus correctly... you get what I mean.

Oh and you're lucky you work 5 minutes from the repair centre. Also... you got it repaired twice?! What's up with that?!





BTW what's the 50L quirks?

Mine's due today. I'll post some samples when it arrives.

First time, it was front focusing at close distances. When I got it back, I tested it there and it couldn't focus beyond 20' - infinity.

50L quirks, well, first off, I've tried 6 copies of this lens (I have friends on this forum who can vouch for all the hassles I had to go through)... It took me 3 months to finally get a decent working copy straight from Canon. Due to the 50L's inherent design, it has 'focus shift' issues when used near MFD-4' and the lens stopped down past 1.8-2.0. That to me is ridiculous.
I trust the sig's AF over the Canon. On the other hand, my other Canon primes are superior to the sig 50... maybe I'm just an anti-50L

It seems annoyingly hard to get a good 50mm prime.

85 you can choose the 85 1.8 or 85L (both are good, one is obviously more expensive). 24mm has it's choices and 35mm has the 28 1.8 (close) 35 f/2 and 35L. All of which are OK (35 f/2 isn't great, but whatever). Then 100mm you have the 100 f/2, 100 2.8 macro and the 135L (a bit longer, but still in that range IMHO). Then at 200 you have the 200 2.8L (great lens) 200 2.8L IS and the ol' 200 1.8.

50 is Canon's weak spot IMHO. The Nifty is OK and cheap, but sucks in quality. The 50 1.4 is good, but the bokeh is a bit ugly. Now the 50L has problems too. Time for a new 50mm lens Canon.

Well, using a focus test chart my new Sigma 50mm required +18-20 adjustment for front-focusing. Just a couple of wide-open shots from around the house (post-adjustment) shot as RAW with basic exposure, WB, and levels in Aperture (no sharpening added):

so of you owners with a camera that has the adjustment... would you send it in to be adjusted or just use the adjustment you have available in camera? I'm not worried about it at all on my 5Dii (the body I'll be using it with most of the time) but eventually I plan on getting a 1Dii'N' and what then? Also, what if I ever want to sell it? Sure my shots will be sharp.... but only because of the adjustment?

How hard is it to send it in?
Where does it go, how expensive is it, and who picks up the shipping?

I'm going to send it in personally because I can't use the lens on my 40D, I too was thinking of picking up a 1DmkIIN eventually so that would also be a problem.

I contacted sigma and they instructed me to send it to the NY center. It looks like I'll be paying shipping, I'm not sure there will be any cost involved for calibrating the lens as it is under warranty.

If it's under warranty it should be gone about a week and shipped back. The only cost will be the cost of sending it to NY (which is where I shipped mine) It's totaly worth it....Is it lame that you have to do this? ......He!! yes....but what you get back is a great 50mm prime....More useful to me than any of the 50L's I've owned

someone post up the phone number? (yes I'm that lazy today)

a Week? I hope that is the case. The whole reason I'm delaying it is because sigma quoted me a 4-6 week turn-around time. Not fun.

I just got mine and it needs +15 on my 5D II. On my 5D it terrible everything is out of focus, which means I won't be able to use it on my 5D.

I don't want to blame the camera because my 5D II performs awesome with most of my lenses, but this Sigma at +15 the out of focus rate is much higher. I'm going to keep on tweaking it and hopefully get it dialed in.

at normal view the pictures at 1.4 - 2.8 are wicked sharp, once I zoom in to %50 the pictures start to get soft.
