EOS Bodies / Re: Auto_focus Acting Up
« on: January 15, 2013, 04:39:03 PM »
I have the same problem with both of my bodies, in low light and trying to AF on fast-action.  It boils down to the fact that I just don't think the 1DX's AF is as good as all the hype when it was first released

I believe this is true.  The Ai Servo AF on 1Dx and 5D III does not seem to warrant all the initial hoopla, especially in Ai Servo.  However, I just got my 5D MkIII back from Canon Service, where I had it cleaned and checked before the warranty ran out.  I did mention to them that the Al Servo mode seems to have tendency to misfocus, and the service summary mentions:

"Confirm autofocus to factory standard (Ai Servo).  It was found that the adjustment of the AF assembly was incorrect, causing the focus to operate improperly.  Electrical adjustments were carried out on the AF assembly.  Product function was confirmed."

There is no way to perform proper A-B testing of Ai Servo in exact same situation pre and post "AF adjustment," but I do believe the Al Servo focusing is working perceptibly better now, which is very difficult to quantify. If your recent Canon body is having unusually worse-than-expected Ai Servo performance, it may (or may not) be worth it to have Canon Service check it out before warranty runs out.  They probably need a cleaning anyway..

Reviews / Re: Review - Canon EF 50 f/1.2L

The only people who bash the 1.2L are the people who can't afford it.

That is not true.  I can easily afford it.  I bought it  I used it.  I returned it.  The focus shift issue was the reason I returned it.  I don't care how sharp or not sharp a lens is if I cannot focus it accurately. 

Do you remember the date code on that 50L and on which camera body?  Reading through the large amount of user reviews out there, one gets the feeling Canon changed *something* with the 50L in the last couple/few years without official announcement, either some sort of hardware/firmware change or maybe even change/tightening of QC.  People with the latest batch of 50L and camera bodies seem much happier than before, e.g. I am very happy with sharpness and focusing of 2011 50L + 5D MkIII combo, with -3 lens microadjustment.

I don't know about that, but despite all the bashing about its sharpness, according to Lensrentals testing, the 50L is the sharpest lens from f/1.2 to f/2.0 including alll Canon, Zeiss, Nikon, and Sigma 50mm choices. 

What I love about the 50L is how it retains such nice contrast and color below f/2.0, which is something my Canon 50 f/1.8 or 50 f/1.4 could not do, not to mention the superior bokeh of 50L .


The X100s is looking on paper to be a very capable street shooter...

I'm sure the X-Pro 2 is going to be very similar.


Personally, I'm thinking X-E1 MkII with the new sensor and a bit improved EVF down the line is what I (and many) would like to wait for at a lower price point than X-Pro 2.

The more I use the 50L for portraits, the more I am appreciating its slightly more "human" rendering of sharpness.  Most of us non-models without full make-up are shown in a more glowing and forgiving light IMO compared to other bitingly sharp lenses.

Why fix what ain't broke?   ???

My thoughts exactly.  I love my 35L to pieces, which also happens to be smaller and lighter than Sigma. 

On the other hand, if Sigma can come up with a 50 mm f/1.2 with super sharpness and great bokeh, that might be something to consider instead of my 50L.  And no, I've tried the Sigma 50 f/1.4, and that is not good enough.

35L is smaller and lighter, which I appreciate very much for all-night shooting.  My copy of 35L is already super sharp, and I really don't need it any sharper in the center; if so, it might even be too sharp for people shots.  In fact, if I plan to shoot portraits, I may grab the 50L over 35L for a little softer rendition..

Will not on my shopping cart until I see FF sensor.

X2 but I'm afraid the chance of that in Canikon land is very, very slim.

OOF lights at f1.4 showing mild ringing/onion:

At f/1.4, aren't the round lights overly football-like in shape? 

Third Party Manufacturers / Re: 5Dmk3 doesnt play with kenko teleconverters
« on: December 03, 2012, 07:35:26 PM »
To get the Kenko 1.4x to cooperate with your 5DmkIII, you must first disable AFMA and then *take one picture*. After that you can swap on your TC and everything should work normally – apart from having AFMA. You can also re-enable AFMA immediately as long as your TC+lens combo doesn't actually use it (i.e. has +0 setting).

I tested this with 100L and 200L/2.8 using the "blue dot" TC.

I just tested this with 5D III, 100L, and Kenko 1.4x "blue dot," and nope, it still doesn't work.  After the "workaround," when I press shutter, the camera STILL freezes up, with taking the battery out the only way to revive it.

I always welcome any good third party lenses.  That really is the only way to force Canon from pricing their lenses so stratospherically in the long run. 

BTW. For the gallery.  For the several Sigma lenses I've used, I have noticed a little bit of color balance difference from Canon L glass.  Anyone else notice this?

« on: November 18, 2012, 09:24:10 PM »
Well, when Canon releases the next 50mm, I sure hope it can match the sheer sharpness of the f/2.5 compact macro, while improving on its 6-blade bokeh, with USM.  Add wider aperture, hopefully at least to f/1.8 and retain 1:2 macro ability, and there's a lens I would definitely buy!

Canon General / Re: Travel to Thailand/Laos should I bring my 5d mkiii?
« on: November 17, 2012, 06:43:36 PM »
Thailand is a great place and worthy of bringing your top gear.  Last time I went to a humid place, I noticed quite a bit of condensation on the lens as the Hotel-cooled camera/lens was taken outside to humid air.  I would recommend bringing an air-tight plastic bag of some kind to keep your camera/lens in when you walk out of air-conditioned hotels.  If you take them out once temperature equalizes between camera and air, you can avoid condensation.  If you have to shoot something right away, make sure to bring lens cloth, as you will likely need to keep wiping away condensation from your lens until camera comes to outside temperature.
