Software & Accessories / Re: What smartphone photo apps do you use?

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

Neato!

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

Do you use the free or paid version?

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.

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.

Canon 28 f/2.8 at B&H for $259

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.

Software & Accessories / Re: Starting out: Flickr? Picasa? PBase? Other?
« on: January 12, 2012, 11:20:51 PM »
I use flickr and showcase my stuff to family using flickriver. Mostly family things. It also works as a screensaver for AppleTV and all that stuff.

I use 500px for stuff I consider better shots.

I don't update either as much as I should.

Site Information / Should karma remain on the forum?
« on: January 12, 2012, 11:00:09 AM »
A lot of issues have come up recently that seem rooted in karma. So I'll let everyone decide in a democratic fashion on whether to keep it around or not.

EOS Bodies / Re: DSLRs are a dying breed, EVIL is the future!
« on: January 12, 2012, 10:53:31 AM »
size does matter. otherwise I would have a 7d  ;)

EVF and AF will be getting better for sure and besides these two, fast primes are the reason for me to use dslr.

it seems the 650d will be my last dslr  :o
since the competition is bigger and bigger I hope it will come with a new sensor too not only with digic5.

btw I hate the fact that if you want a better camera it must be bigger.
like: you want AF-MA? buy a 7D.. pfff.

Size matters, yes.

I use an M9 and Summicron 35 for 90% of what I shoot. I love the size and weight of the thing. I can fit it almost everywhere.

However, sometimes a camera the size of a 1D Mark IV is almost necessary. I cannot imagine shooting wild life or sports with a camera even as small as an M9, nevermind something the size of a NEX-7. The size of the camera adds to its ergonomic advantages. Having easy to access dedicated buttons for nearly every function instead of an LCD driven menu system is a must. You just don't have the space on a small camera to make it great in that regard.

I think we're going to see tons of choice when it comes to size in the future, but the big DSLR isn't going anywhere.

Jobu Design I had met the folks at Jobu Design nearly two years ago at a show in Toronto. At the time I had just bought Wimberley gimbal heads for my lens rentals business and then became aware of Jobu Design.

What is relatively unique about Jobu Design is their range of different gimbal head sizes. The same head isn’t required for a Canon 600 f/4 and a 100-400L, so why pay for a really large head?

The Jobu Design Booth

From Jobu Design

Our unique BWG line of tripod heads suit both pro and amateur photographers alike. With three basic sizes and modular design components it is easy to configure a product to your own exact specifications and price-point.

Made proudly in Canada by Devonshire Manufacturing Group, Inc. We ship our products to happy customers the world over, from Tasmania to Iceland and all points in between.

I hope to do a full review of some Jobu products in the future. I’ll probably take one to Ecuador with me next month.

Short range wireless communication Canon has applied for a patent that would allow short range wireless communication between the lens and camera body, as well as the flash to camera body and live view to computer. This sort of technology could also be used for an electronic view finder.

Patent Publication No. 2012-2984

  • 2012.1.5 Release Date
  • Filing date 2010.6.16

Electrical contact

  • Increasing contact for additional functions and a loss of compatibility with legacy equipment
  • Problems such as dirt and wear

Radio

  • Not a problem unique to the electrical contact
  • Might be intercepted

Canon’s patented

  • Short-range wireless
  • Reduce the output of the radio, about 30 ~ 50mm and the radius of the wave communications
  • Communication from the reach of the waves inside of the equipment is not leaking
  • In range because there is only one model, no pairing
