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?
- 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
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.
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.
All the sample images look very good to me. There’s some NR smearing at higher ISO, but that is to be expected.
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.
I use 500px for stuff I consider better shots.
I don't update either as much as I should.
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
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.
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?
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.
Patent Publication No. 2012-2984
- 2012.1.5 Release Date
- Filing date 2010.6.16
- Increasing contact for additional functions and a loss of compatibility with legacy equipment
- Problems such as dirt and wear
- Not a problem unique to the electrical contact
- Might be intercepted
- 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
