It would be interesting to know if the new 11-20mm will cover a full frame sensor for part of the zoom range like the 11-16mm works at 16mm. That might be the best "feature" of the excellent 11-16mm.

I would imagine so - the 16mm end of my 11-16 works great on my 6D.  It's about the least expensive way buy a new FF 16mm lens with autofocus, and it's and f/2.8 too :-).

On my old 12-24mm Tokina it stopped vignetting on FF about half way through the range (~18-19mm) but then that was an f/4 lens.  I'd imagine that the new 11-20 is probably FF safe at least at the 20mm end; anything wider will depend on the design (almost certainly will vignette at anything wider than 16mm though...).

Any idea if the Canon patents on these old optical formulas have expired?

To me this seems like a "cover your butt" press release than anything else.

I only use Lithium batteries in my flashes & they work great.  They have an extremely long shelf live, good energy density, and they are noticeably lighter than other battery types I've tried, which is a big deal for me as I have a history of trouble with my right wrist.

They certainly have a faster recycle time than most rechargeables.  However, I don't go nuts with it as I know that it'll overheat the flash head.  Like this:  http://blog1.1001noisycameras.com/2010/01/30seconds-to-overheat-adventures-with-the-sb900-flash-and-nizn-aa-batteries.html

EOS Bodies / Re: Patent: Contact Cleaning Body Cap

Besides poor plating, there is the near impossible situation of plating a sharp edge or pointy pin.  You just can't do it.  Pins have to have a nice smooth radius on the end, corners the same.
Most dirty pins are actually due to a thin film of corrosion that is invisible.  It comes from cracks or porous plating, or from the sharp points and edges.
The best designs use a wiping action as the parts come together.  This wipes that microscopic film away. 
The ends of the pins in a DSLR are nicely rounded, but even so, its a weak point.  You definitely do not want to be rubbing on them more than is absolutely necessary.  The thinner that gold gets, the worse the problem is.
IMHO, the self cleaning cap is one of those designs that will do more harm than good.  The lens already wipes the contacts when its rotated into place. 

Awesome post, Spok.  Personally I think that the only EOS contacts that might benefit from regular cleaning are the plates on the lens, & that whatever cleaning a "self-cleaning lens cap" would do should be very, very light.

So far the biggest problem I've had is the design of the 24-105L rubbing through & shorting out the internal ribbon cable over time, which makes for a nasty error message at any focal length other than 24mm.

great idea, daddy likes.  Assuming the price increase vs. a normal body cap is minimal i.e. this is a <$10 product, unlike a certain German brand that wants $50 for a round chunk of plastic.  Given that it weighs about 46g that's ~$1/g, which it turns out is the same price as something you need to be smoking in order to pay that kind of money for a plastic body cap.

I'd find a contact-cleaning lens cap even more useful as I hardly ever use body caps but I use lens caps all the time.

Perhaps if Canon collaborated with more designers, we'd get more functional gear.
Thinking back of the T90 when Luigi Colani was re-interpreting camera design and seeing that this is still the major design approach of todays EOS Cameras... I think you're right.  :)

Ah, the father of modern SLR ergonomics :-)

some of his other stuff is pretty crazy though.  Even some of the cameras were pretty bonkers looking, not to mention the Darth Vader trucks...

Still, '80s design at its finest <grin>

Like Apple, Canon has realized that some of their products are as much fashion accessories as they are electronic devices (or at least they want them to be :-), and is acting accordingly.

Personally I think that statement applies to a lot of their smaller cameras, but I'd be surprised if anyone gives a crap what you carry your DSLR around in (from a fashion perspective).

Lenses / Re: Do you keep all your boxes?

I like to know if you keep all your lens boxes? I can imagine that it's useful to keep the camera box , but do you keep all the other boxes too?
Keep in mind that I am a minimalist ;)

I cut the UPC/bar code off the box with a pen knife as proof of purchase (along with the receipt) & chuck out the rest.

As much as keeping boxes around to potentially increase resale value is tempting:

 - I have a small apartment where space is at a premium; there's no place for empty lens boxes here.  The available space in the cabinet is worth way more than the few extra bucks I could potentially make several years down the road.

 - I usually end up keeping my glass for a long time, and 5 year old lens boxes tend to be so beat up that they're not presentable anyway.

The watch is just a quick glance away compared to other devices such as your phone which could be in a pocket. Though i think habit has a lot to do with it. Even with my phone in my hand, sitting on a train, I always instinctvely glance at my watch to check the time so I don't miss my stop.

Agree wholeheartedly.  I began wearing a watch again when I started cycling to work.  Try pulling a phone out of your pocket on a bike just to check the time...

You know what I'd really like in terms of radio options built in to a camera:

 - GPS with an intelligent power function connected to the inertia/orientation sensors already in the camera so that it switches off the radio when the camera isn't moving.  It should also have an option to switch off the whole GPS unit when the camera goes to sleep.

 - Bluetooth 4.0 LE radio, with apps to take full control of the camera from a computer or smartphone.  The bluetooth radio is a dual-mode radio that also supports "classic" Bluetooth & will need to be paired in this mode before it can be used as a remote viewfinder (which requires more bandwidth than Bluetooth LE but should work just fine with regular bluetooth 4 if the "viewfinder" video stream is sufficiently compressed).

Lenses / Re: Selling my two Zeiss lenses. Your advice?
« on: July 27, 2014, 05:49:35 AM »
Among other awesome glass, I've got a Zeiss 35mm f/1.4 Distagon.

It's the old Contax/Yashica mount version.  It says "Made in West Germany" on it & is built like the proverbial brick latrine.  Since it's an "obsolete film camera lens" I picked it up for chump change.  I've got about 1/3 as much invested in the EOS adapter on it as I put towards the lens.

I keep it at hyperfocal at f/4 or f/5.6 most of the time, except in low-light scenarios.  I admit that other than the first year or so after I got it it mostly lived in the "storage" camera bag as it's pretty heavy compared to most of my Canon primes.

Then I got a 6D, and started using it to shoot short video clips.  The "look" this thing gives combined with the short DoF & really long focus throw makes it completely awesome for video.  The old-school straight aperture blades make for starry highlights too, which may be spiffy or a hinderance depending on the situation & personal preference.

May I suggest that you want to part with these things because you feel you have a ton of cash invested in them without a corresponding return?  Personally my mantra with lenses is "if you've got a good lens & like it, then keep it unless you get something else that totally obsoletes it.  & if you've got an emotional attachment to it (for the images you've made with it, not because it's a nice object), then keep it anyway as you'll regret selling it" (my profile icon is a long-lost friend the T90).  If you can afford to do that of course; if you're out of work & the rent is due then you've got some tough choices to make, so start with the ones you use the least.

I can't speak for the 15mm or 135, but the c/y mount 35mm f/1.4 Distagon really inspires me when I use it, especially for video.  If you get similar pleasure out of your 35 then keep it.

Personally my experience after having owned a bunch of manual focus glass is that the wide-angles are easy to use & get used a lot, and the telephotos are frustrating for anything except controlled situations like portrature where you have the time to review & go back & do it over again & again until you get what you want.  Speaking as a long-time owner of the Canon 135L, if the AF is adjusted to where it really hits right I get as much joy & satisfaction out of using the Canon 135L as the Zeiss 35.  Those are probably the two stand-out lenses in my bag that I really try to use as much as I can (whenever the situation calls for it).  I also really love the Canon 85mm f/1.8 USM as it's sort of the little brother of the 135L, and the 40mm pancake "lives" on the camera as it's a really appropriate length for a lot of situations & it makes the 6D small & light enough that I can comfortably carry it in a coat pocket or messenger bag (much to the chagrin of my Fuji X10 which has seen basically no use since I got the 6D/40mm).  The 20mm Voigtländer also fits into this category.

The 85mm USM and 20 & 40mm pancakes all fit into one Canon lens bag which I can take pretty much anywhere if I need to.  In fact ever since my 24-105L developed an electrical short that prevents it from zooming beyond 24mm, that's 20/40/85 combo in the lens bag is pretty much my go-to travel kit.  The 135L and 1.4x TC go into the shoulder bag as well when I think I'll need anything longer than the 85.

Anyway, with that little tangent over, IMHO:  sell the ones that inspire you the least, and do check out the Canon 135L as it's more versatile than the Zeiss & you might even make money on the replacement.  With a little luck Canon may even release an IS version now that there's some healthy competition in the "fast 135" space...

Awesome news for Andy & the Gura crew!

"brand & assets" sounds like they get to cherry-pick the interesting bits that they want to keep & throw out most of the fat that probably led to the bankruptcy...
