Awesome shots! congratulations to the winners, i was wondering what is the abstract actually a picture of though?

It's a microscopic photo of a crystal.

It took me 8 months to get the M9 approval.

She's glad now, it's a lot lighter in her purse than a full fledged DSLR  :D

It is, what I want to do is quite elaborate.

Finding an app developer has been more difficult than I thought it would be. It's apparent Canon Rumors needs an official one.

2012 is the year I get it done, come heck or high water.

Third Party Manufacturers / Zeiss Distagon T* 25 f/2 ZE in Stock

Carl Zeiss Distagon T* 25 f/2 B&H has limited quantity of the new Zeiss Distagon 25 f/2 that was announced at the end of October.

As per most of the Zeiss lenses, it’s coming highly regarded. Here’s just one review.

Hey, that's interesting. I'm not sure they can do that... I've never commissioned an app.



Wow, I figured this was the official, authorized, CR app.   None the less, I love it.

Do you use the free or paid version?

Canon General / Patents: 24mm f/2.8, 50mm f/1.2, 300mm f/4

New Optical Formula Patents A new patent showcasing 3 different focal lengths has come to light.

  • Patent Publication No. 2012-8352
    • 2012.1.12 Release Date
    • Filing date 2010.6.25
  • Example 1
    • Focal length f = 294.0mm
    • Fno = 4.14
    • = 8.42deg angle.
    • 15 sheets 11 groups configured
    • One element radial refractive index profile
    • Bowen ratio 0.78
    • Inner Focus (the second lens group for focusing)
  • Example 3
    • Focal length f = 51.5mm
    • Fno = 1.25
    • = 45.6deg angle.
    • Configuration 6 each group 10
    • Two elements radial refractive index profile
    • One aspherical surface 1
  • Example 4
    • Focal length f = 24.7mm
    • Fno = 2.86
    • = 82.4deg angle.
    • Configure each group 11 10
    • One element radial refractive index profile
    • Rear focus (the third lens group and the second lens for focusing)
  • The principle cause chromatic aberration
    • Light is refracted at the interface of the lens
    • Within the lens are not refracted rays
    • The refractive index is different for each wavelength
  • Element and the axial refractive-index distribution is
    • Refractive index change in the direction of optical axis
    • This patented technology is not used (as introduced)
  • Element and the radial refractive index profile is
    • Refractive index change in a direction perpendicular to the optical axis
    • Rays are refracted at the boundary and both the lens in the lens (chromatic aberration occurs).
    • Chromatic aberration can be corrected if appropriate refractive index profile
    • Rather than spherical or aspherical, planar (flat glass), but I (easy processing)
  • Canon’s patented
    • Elements to create a radial refractive index profile optimized for each wavelength the refractive index profile is difficult
    • Patented technology, the characteristics of chromatic dispersion (Abbe number, a partial dispersion ratio) to optimize, to compensate for chromatic aberration
    • Optimize the calculation, line d, line C, line F, to compensate for chromatic aberration of four wavelengths simultaneously in the g-line
    • Create a radial refractive index profile element as a mixture of resin

Lenses / EF 24-70 f/2.8L II [CR2]
« on: January 15, 2012, 06:00:02 PM »
Here we go again More information has trickled in about the “thorn in my side”, aka the Canon EF 24-70 f/2.8L IS II. A new version of the updated lens started to make its way to the folks lucky enough to test the lens out. There have been upwards of 5 different variations of the new lens. It’s still reported that there is no IS in any of the prototypes. One design change that has apparently been seen is a fully internal zoom function, we’re not sure if that is with all the prototypes.

I won’t even hazard a guess as to when it will be announced, though it was suggested it has been pushed back on various occasions.

I can see the collective eye rolls about this post already. I post about 2% of the stuff that comes in about this lens, I understand you’re all sick of reading about it.

EOS Bodies / Canon EOS-1D X Battery Issues?
« on: January 15, 2012, 04:19:53 PM »
Why the delay? It’s been noted that an official weight for the new Canon EOS-1D X has yet to be finalized, I’m told the battery is the reason for this. It was suggested they’re having “serious” issues with the new battery.

Firmware Another person has come forward and said Canon is working feverishly on firmware feature changes and updates to the EOS-1D X. The good news is Canon will do whatever it takes to get the camera to market in March as previously announced.

Pricing Change? I’m told the $6800 suggested price tag for the EOS-1D X isn’t written in stone.


PowerShot / New PowerShot G1 X Sample Images
« on: January 15, 2012, 04:09:20 PM »
From LensTip The folks at LensTip have posted full sized sample from the just announced Canon PowerShot G1 X. They took shots at various ISO and aperture settings.

All the sample images look very good to me. There’s some NR smearing at higher ISO, but that is to be expected.

Preorder the PowerShot G1 X from B&H for $799


Stolen at CES? The Sigma 180 f/2.8 OS Macro lens that was showcased at CES 2012 in Las Vegas, Nevada has gone missing.

The lens was one of 2 pre-production models believed to be in existence. If you took it, give it back. For the record, I touched it, but I left it at the Sigma booth.

Lenses / Canon EF 28 f/2.8 Disappears From Price List
« on: January 13, 2012, 09:04:38 AM »
From Germany According to [NL], The Canon EF 28 f/2.8 no longer appears on German price lists. This lens is one of only three lenses left from the original EOS line-up. The other 2 being the 50 f/2.5 compact macro and the 135 f/2.8 soft focus.

Another lens that has been out of stock for some time at B&H is the Canon EF 35 f/2.0. We have heard previously that a 35 f/1.8 does indeed exist.
