Lenses / Re: Practical use of the ef 50mm 1.2L
« on: January 30, 2015, 09:04:10 AM »
This is the clearest demo I've found of focus shift on the 50mm 1.2.  Shows various apertures at 2', 3', 6', and 10' distances.

And...I've had a change of heart.  Good encouragement here, along with doses of reality.  Thanks.  I'm going to refuse the delivery next week.  Simply too much trouble to try and master at this point.  I will live with the lenses I have until Canon either fixes the focus shift with a new design or Sigma demonstrates they've fixed their AF inconsistency with a firmware update or whatever it takes.
I understand your concerns based on Internet sources, but I would at least give the lens a try.  You can always return it.  Or if you want essentially the same lens without as much focus shift and not as soft, but with other issues (slow AF driven by wire, shallower DOF, exposed glass on mount), give the 85L II a try.  These are both specialty portrait lenses that aren't easy to use, but not impossible, either.  The results when shot between f/1.2 and f/2 are stunning, however.

Has anyone figured out what this does?

Improves the AF controllability when shooting in Live View mode with a wide-angle lens (fixed focal length or zoom).


I'm hoping it will enable live view autofocus on my TS-E 17L...   ;)
I heard that it will do that for the TS-E lenses (can't wait to try it), but Canon intentionally disabled AF for Zeiss lenses with this firmware ;)

I think the update means a new UWA is coming. It's generally for that lens instead of existing ones
That's a definite possibility given the rumored 14-24 f/4L.

BLASPHEMY!! It's 11-24!  ;D ;D

Wow, I really haven't been sleeping much lately!  I must have crossed over the the dark side (black telephotos and backwards rings) for a moment.

Please forgive me :-[

I'm curious also, wonder if the 2470 classifies as a "wide angle" lens?

Installed and working at least.
I'm hoping it fixes the issue that happens when you scroll to the edges of the LV AF area (which isn't the edge of the screen) and the cursor/zoomed view snaps back to the center.  Hopefully it will just stop now, and won't surprise me by jumping back to center making me scroll all over again.  Or better yet, maybe it will go to the edges of the screen and stop there.

Congrats on the purchase as well.  I have owned two copies of the lens and I think you'll love it.  It, along with the 85 f/1.2 II are pretty much the only lenses I use for portraits.  Other lenses work well for other subjects, but the shallow DOF, color and contrast of this lens really makes for special portraits.  With a little one, you'll fall in love with it right away.

I generally shoot between f/1.2 and f/2 and have never noticed the dreaded focus shift on either copy.  Perhaps it's because of the aperture, or perhaps because of the rumored change that Canon made some years ago to improve this behavior.  I also believe a lot of the reported problems are related to the fact that shooting at f/1.2 is very difficult and the closer you get to the subject, the shallower the DOF becomes (paper thin).  Your best bet is to use FoCal or another tool to AFMA the lens (pretty critical), and take multiple shots, re-focusing between each one.  You'll find that your keeper rate at f/1.2 up close is going to be pretty low - maybe 10-50% in low light, higher in good light.  Be patient with it if you shoot wide open, as you get more comfortable with it, you'll find your keeper rate will go up.  Be sure to use your camera's focus points as the focus and recompose technique doesn't work well due to the field curvature and shallow DOF of this lens.  Also, you can always shoot in M mode and bump up the shutter speed to 1/100s or higher to give yourself a better margin.

EOS Bodies / Re: New 1DX firmware info by Fred Miranda site member

The updates are both up - the leak was correct.  No info on exactly what #1 does.  I'm in no rush to update my firmware - will let the guinea pigs go first :)

Very interesting, and I haven't experienced any of these issues, but I wonder what #1 is all about:

1. Improves the AF controllability when shooting in Live View mode with a wide-angle lens (fixed focal length or zoom).

Will they finally fix the cursor (whatever it's called) from snapping back to the middle when you reach the edge of the LV focus area?  That's been a pet peeve of mine forever.

I would have stuck with my point n shoot and saved $30K in gear
LOL, I got the red ring fever, then the 5D diagnosis, then the big white infection, and finally the 1D dose of death.

I could probably do a lot more with a P & S with the things I've learned along the way :)

Here's the solution, written by the late Uwe Steinmueller:

You should probably PDF this page as I'm not sure how long his widow will keep everything online.

I recently sold all my Canon gear with the exception of my 70-200 2.8. I was hoping to downgrade some of it since I am trying to cut back to more of a hobby rather than pursue photography professionally. I just do not have the time in my life so I got a chance to get all my money I paid for my gear and even made a little. The question is I still need a body and a mid zoom like 24-70 2.8 II and a prime. I just am torn if I should wait a few weeks or take advantage of the 1dx rebates and grab a 1dx now and the 24-70 and wait for the rest till the announcement. Either way I plan on saving some for a nice vacation with the family. Any help would be appreciated.
I'd go for the 1D X and 24-70 II while the getting is good.  They're selling for insanely good prices compared to what most of us paid and unless you need lots of pixels or a smaller camera, I don't think you'll find a better camera than the 1D X.  As for primes, that's a personal one, but the rebates are good on them as well.

East Wind & takesome1, thank you for your perspective as 1D X owners.  I had a feeling it wasn't quite as great as hyped (compared to the 1D X), but it still sounds like a huge leap over the 7D.  I think I'll keep an eye out for a refurb down the road, but the 1D X and 5DIII serve my needs just fine.

Also, keep in mind that Art Morris has pretty specific needs when it comes to AF, so I'm not surprised that he's more annoyed by this than most people.

Lenses / Re: 400 DO II continues to test out as superb
« on: January 28, 2015, 09:17:13 AM »
Still amazes me that with one stop down and no IS, the vintage 400 f/5.6 is still a contender at roughly 1/5 the cost. Imagine how great it would be updating with IS and say 1/4 cost.
Having owned one for many years, it doesn't surprise me at all.  I have to say, I was somewhat disappointed when I bought my 300 f/2.8 II IS - it's better than the 400 f/5.6, but not by a huge amount.  The IS and 2 extra stops (or even 1 with 1.4x) make a massive difference, however.
