Lenses / Re: 85 1.2 L2 not sharp at 1.2

i even tried manual focus and AFMA.

MF via the viewfinder or via live view 10x?  Did you try Live AF?  How did you do the AFMA?

I can't see it being a general 60D issue. Unfortunately, it might be an issue with your 60D.

EOS Bodies - For Stills / Re: Thoughts on the New EOS-1D X Firmware 1.1.1

AF5 menu option 3, VF display illumination, press set, then Q, then set it to Illuminated.  But yes, I have menu item 2 set to selected/constant, but it flashes in servo with other settings there (pre focus, etc.,) except off.

Actually, with display during focus set to off but servo illumination on, the red light flashes anyway, but no points are illuminated. That seems wrong, although that may be intentional, Canon might think we want the grid display to flash or something...

Help,needed please
 I’ve just downloaded the new firmware version 1.1.1 & the auto focus point is still black in AI Servo? But still flashes red in one shot. Any ideas.
I have re downloaded the firmware twice & reinstalled it 4 times & it’s still the same not lighting up red in AI Servo.

Erm...did you turn it on in the settings?  AI Servo point illumination is off by default.

Lenses / Re: looking for equivalent to efs 17-55 f/2.8 in EF line
« on: October 23, 2012, 06:09:03 PM »
The FF equivalent of the 17-55mm f/2.8 is a hypothetical 27-88mm f/4.5 lens.  So, compared to the 17-55 on APS-C, the 24-105 on FF is wider, longer, and the aperture is 1.3 stops wider in terms of DoF for the same framing.  Yes, it's still f/4 for exposure, but the FF sensor also has at least 1.3 stops less ISO noise (more like 1.5 going from 40D to 5DII), so you can bump the ISO to make up the stop and still be ahead on noise.  Overall IQ of the 24-105 on FF is better than the 17-55 on APS-C, and you keep IS. The only thing you're giving up is the activation of the f/2.8-sensitive center AF point.

Politics and conspiracy theories aside ...
It is entirely possible the exclusion (at least for now) of the AI-servo AF illumination for 5D3 may be a technical one.

I trust we all understood why AF illumination was avoided in the first place -- interference with the on-board metering system. It was due to popular demand that Canon have since come up with a clever, although quirky, work around with the 1D X. Perhaps it is the lack of an RGB metering system that precluded the same work around from working reliably, if at all, on the 5D3 (and 7D too should they decide to). The red RGB channel could have provided the necessary reference feedback to actively tune out the LED illumination interference through software. This magic trickery may not be feasible with the color-blind 5D3/7D metering sensor.

Excellent point, and a very real possibility (although the 7D/5DIII metering isn't color-blind, it's a dual layer sensor with red/green and blue/green layers, but the point is there's no specificity in the red channel, and it may be that the 1D X just ignores that channel when the illumination flashes).

It's rather ironic that people do obsess over resolution so much when for the majority of them, their final publishing platform is the web, at low densities and tiny sizes relative to even an 8x10 print.

Hey man, don't slam on my facebooking, k?   8)

EOS Bodies / Re: Does google use Canon?
« on: October 23, 2012, 04:30:01 PM »
Not to worry, it's most likely just a post processing artifact used by Google at the request of the US Government to hide the sensitive military installations hidden in the shadows in that part of Oregon.

Wait what? Can someone elaborate on this? Does this mean the 5d3 doesn't spot meter exposure with points other than the center?

The reason why im concerned is because alot of my shots with the 5d3 always end up underexposed even though the on camera light meter says its spot on.

If you set Spot Metering on the 5DIII, it uses the spot metering circle in the center of the frame, regardless of the AF point selected. If you want to spot meter for an off center subject, you must put the metering circle on the subject, lock exposure with AE Lock, then recompose and shoot.

The 1-series bodies can spot meter at any of the 61 AF points that is selected, if that function is enabled.  Hey, >$3K has gotta buy something, right?  ;)

This was discussed in another thread.  Seems that CRguy has implemented some new software to help further reduce spam presence in the forum, and the kinks aren't all worked out yet.  I'm sure things will be back to normal, soon.  In the meantime, I guess we should be grateful the forums aren't inundated with ads for Louis Vuitton bags and DVD ripping software, right?

Your bird pic from the 1D X is far too soft.

Yeah, it's front-focused a bit, for one thing, and needed a deeper DoF - but it was overcast and near sunset, and I was already at f/4 and ISO 6400...

This was rejected for being too noisy.

Is that a 100% crop, or is that the full or slightly cropped image?

do i miss something or where is a link to the source?

It's up on PR Newswire and Business Wire - it's not uncommon for corporate press releases to hit those wire services before they get them up on their own website.

I'd reject that 2nd bird if I was a moderator.

It was in a tree and eating seeds.  I get confused easily...   :o

The new firmware update will be available, at no charge, in April 2013 from the Canon U.S.A. website and can be downloaded by end users or through Canon Factory Service Centers.

Oh, and 5DIII users have to wait 6 months to get it...
