Third Party Manufacturers / Re: Sigma 50 1.4 Art NOT bokehlicious?

Bokeh is great.  AF can be awful, but some are finding it adequate. 

Does that sound like "obsessive insanity"?   If you like to play the good copy game, have fun!  Or, wait for the firmware upgrade. 

I too was hoping that some of the most dependable, articulate posters here at CR were wrong about the AF.  They weren't.  I'll wait until next year before trying again with this one.

Don Haines had a good idea, get some credit in a practical way. 

If you kind of, sort of said they could use it, take it as a lesson.  Whenever you use your camera and share the images, if you want credit, if your heading towards pro or semi-pro, have a plan in mind.

Consider visiting the Professional Photographers of America website--they have some good info for free.  Members get more detailed © protection discussions, plus access to decent templates for contracts and model releases.

At the very least, you've gotten something good for your portfolio.  While the shot itself is quite a nice one, having it used so prominently in this rolling ad boosts its usefulness as a feather in your cap for future jobs.

 ::)  Note that AFTER writing this post, I went back and saw in your signature that you have the f/4 version of the 70-200mm.  That complicates the decision, a little, I suppose!  Enjoy whatever you get!


Lets talk practical for a moment.  The 85 1.2L produces beautiful bokeh, but it is a specialty lens.  Not every shot in a session or a portfolio should have razor thin depth of field, so, for very versatile portrait work, as a tool, the 70-200mm 2.8 IS II offers much, much more, and costs pretty close to the same as the 85.  True, its MFD is about 10" further than the 85, but, beyond that, it is useful in so many, many more situations, not just for formal portraits, but events, sports, nature, and landscape.

The 70-200mm produces DoF shallow enough to be impractical at times, meaning, just like with a faster but shorter lens, you have to be mindful of details that you might want sharp but can start melting into dreamy bokeh.  Neuro could give you all the math, I'm sure, about focal length and aperture producing OOF areas in a photo.

Not everybody has the right head for 85mm.  There are certain shapes of skulls and faces that benefit from the compression of a longer focal length.

Few working pros, if faced with a budget that allows only one lens, would go for the 85 over the 70-200mm.

Don't forget--the 70-200 has lightning AF--and IS!

Would I ever give up my 85mm 1.2L II?  Only if, heaven forbid, forced to choose between that and my 70-200mm.

So where else is this lens being discussed in English?  Sigma Rumors looks like nothing but a promo site.

B&H reviews are all 4 & 5 stars, don't see chatter about the AF problems.  Amazon has a few mentions of the AF woes, but I bet those are from CR members!

As for those here buying up to 4 copies to find a good one, consider this: If you are able to order and receive one within a week or two, you are almost certainly getting one that has been exchanged, meaning you are increasing your chances of getting another bad one.

I'm hoping Sigma comes clean and publicizes the fix(es) when and if.

I'm also hoping Canon comes up with new version of the 50 1.2 in the meantime.

I'm full of hope.

Based on seat of my pants calculations it seems like these lenses have a problem in about one out of three cases.  Does that seem fair?

No spray?  Shoot at a different time or place.

I hate those gnats.  They go right into my ears.

All Sigma lenses have focusing problems! I had two of the a 24-700 and 70-200 last versions - I sent them to be calibrated with my body and then everything was ok.

This is FALSE.  I have two Sigma lenses that have had no focusing problems.  (I don't consider improving AF accuracy with in-camera AFMA to be part of a "problem.")

But the 50 Art that I received did have erratic, unreliable AF that could not be helped with AFMA.

So, if online chatter can lead to Sigma fixing the problem, we aren't helping by using sweeping, ranting statements such as "All Sigma lenses have focusing problems!"

Dilbert, you are misunderstanding "inconsistency."

The 50 Art can be perfectly calibrated, yet still misses focus on too many shots. 

You get your AFMA perfect, then you get into a shooting situation, and one shot will be just right, then the next three will be terribly front or back focused.  I know--that is exactly why I sent mine back.

After trying for 10 days to get the 50 Art to function properly, I went back to using lenses that do work, such as the ef 85mm 1.2 L (so I know all about shallow DoF) and the ef 24-70mm 2.8 II L.  WHAT a FREAKING relief to have sharp, accurate, 95% successful AF!!!

Dilbert, do you understand now?  The 50 Art, for whatever reason, can be perfectly "tuned" to match a body, and still be all over the place.  If you happened to get a copy that does not exhibit such behavior, stop trying to tell others that there is some kind of user error or misunderstanding.

And, btw, I have a 35 Art that is almost as reliable with AF as my 24-70 (the best AF I've ever seen), and a Sigma 15mm 2.8 fisheye that is spectacular.  Those work.  I think I made a mistake buying the 50 Art before Sigma, using its customers as testers, figured out what is wrong with their production. 

As for the USB dock, it might make things worse for Sigma customers, because now there is this extra level of trouble-shooting Sigma tech support can use to delay actually finding out the true problems with their lenses.  Customer calls Sigma complaining about erratic AF, Sigma asks, "Have you used the dock?"  Customer buys dock, gets frustrated, return time to merchant has expired...Seems like it will cause more problems than it fixes FOR THOSE CUSTOMERs WHO KNOW HOW TO AFMA IN CAMERA.

I bought my 35Art last October, and it had, I believe, the third generation of firmware.  It did need AFMA on my 5DIII, nothing extreme, but it is super accurate with AF and produces spectacular landscapes stopped down, and lovely close-up stuff with better bokeh than the ef 35mm 1.4 L that I sold.  Very little CA even wide open, solid build.  I love it.

But I'm no Sigma fan after being teased by the awesome IQ of the 50Art, only to be let down by erratic AF beyond five feet.

The 35Art spoiled me, and I'm in a hectic time now, so I did not want to pay another $60 for the USB dock, spend a lot of time working with it, and possibly find that the AF was still erratic (not just in need of calibration).

So...Before I got the 50Art, I would have gushed about Sigma.  Now I just scratch my head.

Funny, Viggo, you mention the 85L, because I was just telling a friend that the 50Art had the best bokeh under 100mm I've seen on any lens EXCEPT the 85L II.  I know, the 85 has clunky AF, but for portrait stuff, it truly excels.  Also, I've had minimal issues with CA, and I'm usually shooting between f/1.2 and f/2.2.  But I do control my backgrounds for portraits, don't play much with lens flare or include metallic surfaces or reflections on water with the portraits.)  Not good for much else, but I still think it is the best at what it does.  (But I did give up fast on the 50Art.)

Two:  A GREAT fast-wide zoom, sharp edge to edge, minimal distortion. 

A 50mm1.2 with Sigma Art sharpness, and kickass AF.

Fast-wide zoom is my top wish.

I don't think anything except IS could improve this lens.

One little quirk, though:  I find that when using the deep, cup style hood, I have to consistently over expose by about 1 stop.  Without the hood, it's inline with my other lenses, about 1/3 of a stop EC for a nice histogram.

Love it, and think it's probably the best portrait lens for the money anywhere.  And lately, I've started taking it along for landscape, leaving my heavy, more expensive 70-200mm resting at home.  Great for landscape.

Just got my RMA from B&H.  Simply don't want to deal with the dock.  Also, just read on the lensrental site that they have had "multiple" problems with the lens locking up during adjustment on the dock.

And I don't play the "good copy" game.

Lovely bokeh, all around IQ, but I'm too spoiled by AF to give it up for MF!   :-X

To help with the decision making process, whether to keep or ship back the 50 Art, I called Sigma Tech Support.  Got right through.  Yes, they recommend the dock, but the surprising bit I heard was a vehement denial that Sigma "reverse engineers" their AF systems.  The tech said that "Japan is a socialist nation, and they don't keep these things secret.  Sigma works with Canon.  We get our specs from Canon.  Anything other than this is internet fantasy."

He also went onto say that the 50mm Art is a "reverse telephoto...a VERY TOUCHY type of lens."  This as an explanation for why the dock is so important.

Had a photo session this morning, using my ef 24-70mm 2.8 II.  How wonderful to hit the focus every time, not worry.
