Canon General / Re: Lens stuck on the dock in California
« on: February 26, 2015, 01:56:49 PM »
There are ships stacked up off shore that cannot unload due to the Longshoreman's strike.  A settlement has been reached, and unloading has begun.  It will take at least 2 months to clear the backlog.

Hope only 2 months - I have heard estimates of 3-6 months.

That's entirely possible, and other factors like a possible dockworkers strike are looming.  Canon is shipping the 11-24mm lens this week, so its possible to get lenses here by air or a alternate surface route.

Lenses / Re: 16-35 F4 Restock Date in Canada?
« on: February 26, 2015, 01:49:15 PM »
Hi All,

First post here!

In any case, I cannot for the life of me find the 16-35 F4 in stock anywhere in Canada (I've called coast to coast), and nowhere seems to be getting it in any time soon. Have had one on order for about 2 months now, and the store has 41 backordered. I see plenty in the states, but the dollar is too low to buy from over there.

Anyone here have the inside scoop for when they'll be shipping the next batch to Canada? I'm hoping they'll be on the boat with the 11-24 but I'm not holding my breath.
My bet is that they are with all of other Canon shipments in Long Beach, California where the Unions held the port hostage went on strike for a while.  There's a huge number of ships waiting offshore to be unloaded.  I'm sure this is the first of many temporary shortages we'll be seeing as this cascades through North America.

Canon could air-freight high priced lenses from Japan if they were in danger of missing out on sales.  I have a shipment to import, but have been waiting for the port situation to resolve, since I'm in no hurry.  Air freight is $8 a KG(Canon would pay a lot less), and I import heavy items, so the cost of air freight is about 3X the value of the item.  For lenses weighing 2KG and wholesaling for around $1,000 and more a additional $ 8-16 is not going to break the bank. 

I expect that the $3K 11-24mm lenses shipping this week came by air.

EOS Bodies / Re: Patent: Multi Layer AF Sensor
« on: February 25, 2015, 08:33:59 PM »
Does this mean we should be debating the DR of autofocus chips? :O ;D

:-)  They certainly seem to have DR on their minds.... I bet the R & D area has DR on their Coffee mugs :-)

Where did you see anything discussing DR in the patent?  I waded thru most of it and saw no mention of DR.

It can handle a wide dynamic range of lighting conditions for AF in ideal fashion, being optimized for both blaring sun and dim dungeons.

I think you are joking, but just in case ...

Here is a copy of the Claims from The Japanese patent website as converted by their translator to English.  I see no claim as to improved DR, or even a mention of it.

To answer your question, DPAF is night and day better.  Still, DSLR's are not video cameras, they are still cameras that do video.  There are a few that others have mentioned that are better at video, but the drawbacks are also numerous.

If you are just doing casual video, a 70D is a big jump over a Rebel.  It also has AFMA, which allows you to fine tune focus.  This is a big benefit for wide aperture lenses.

"This is bold prediction, but it’s clear to me that over the next several years, the standalone still camera will disappear from the hands of everyone – with the exception of a few high end professionals."

I disagree.  Cameras (still and video) have always been sought out by hobbyists, and they always will be.  Look at the impossible project, reviving interest in relatively low-quality instant film cameras.  And the number of people hauling DSLRs to their kids' events.  There will always be people who want to step away from the "entry-level," whether it is a smartphone camera or a point-n-shoot film/digital.  Smart cameramakers will simply step-up their integration with smartphones.  A digital camera is just a computer attached to a lens.  I think that enough people are yelling about the demise of the camera and the rise of the smartphone that Canon, Nikon, Sony, and Fuji are going to be willing to listen and consider how to do that.  It just won't happen as quickly or efficiently as we'd like.  The end result will be smarter cameras, and, hopefully, better lenses (since a cameraphone can't compete on optics).

There are still people who buy tube type Audio equipment and reel to reel records as well as vinyl disk players.  I have a whole room full of them. 

However, the number of buyers is so small that's its not a mass production business, and its expensive.  These are simple devices that almost anyone can manufacture, Cameras are not, so those wanting them will have a limited selection of high end cameras, or will be buying on the used market.

Capabilities and innovation in the phone market is going to bring a lot of improvements.  That's where the money is, and that's where R&D dollars will be going.

EOS Bodies / Re: Patent: Improved EF to EF-M Adaptor
« on: February 25, 2015, 12:38:19 PM »
The EOS to M adapter is basically a TC with a very slight magnification, which has different interfaces on each end. The slight magnification eliminates some of the vignetting caused by the adapter.

Just to correct the current EF to EF-M adapter has no any optical elements, just hollow air. It's just a flange-distance corrector with electronics, no magnifying or reduction. Fun fact: If you put Speedbooster optics (focal reducing) in the eos-m adapter, it would turn the EOS-M cameras into a Fullframe mirrorless for 200$ new body.

We are talking about the patent for a new EOS-M adapter.  Did you miss that?  It does have lens elements in it!

I'll agree with his premise

"The key is that the software on those smartphones, and the social media platforms and instant connection to the web – ARE BETTER and cannot be overcome by camera companies that fail to integrate software within their camera bodies going forward."

The vast majority of camera users are using social web sites for their photos, and a phone which uses the vast wireless networks in place around the world has a huge advantage.

Cameras that use Wi-Fi are clunky, and can only connect with a lot of effort when and where a appropriate Wi-Fi is located.  The near field connectivity that allows you to slowly transfer images to your smart phone is not a solution.  I don't know if there is a solution that will save the camera from obsolescence.  Having a phone connection in a camera might help, but sending data over wireless is expensive, so you will have to pay for a additional device on your phone bill as well as $200 or more for the electronics.  The price then becomes a factor.

Professional users could absorb the cost, so its something that needs to be offered now on high end cameras.  I expect Samsung to be the one to do this.

I could see this patent used in a TC.  AF gets slow at times using a TC, and this could speed it up.  The EOS to M adapter is basically a TC with a very slight magnification, which has different interfaces on each end. The slight magnification eliminates some of the vignetting caused by the adapter.

Landscape / Re: Landscape paradise: Colorado vs. Pacific Northwest
« on: February 24, 2015, 11:22:09 PM »
I live less than a days drive from most spots in the Northwest, from Yellowstone to Port Angeles to Medford Oregon, Even Salt lake City.  Yet, I've never really taken a photo trip, except to Yellowstone, and there I was not well equipped.

I envy those who are willing to make the effort, I may do it yet.  I only need to drive 5 miles to see the rolling wheat fields, they are bright green right now.  They should be covered with snow, but the weather is weird. I've thought of setting up once every week or two at the same spot and capture the various phases of the wheat growth from brown soil to snow to green to gold to stubble.

As always, its interesting to see the comparisons of the lenses in a way that no other reviewer can show us.

I will be interested in seeing the results from the new Canon ultra wide zoom.  They probably will not be spectacular due to the extreme wide angle, but at the price, they should be no worse than these.

I gave up on buying ultra wide lenses, because I have no talent for using them, and no matter how good a lens is, the talent of the photographer is 10X more important.
They definitely have some cool test gear and interesting reviews.  I like that they test multiple copies, too.

Also, your comment about giving up on ultrawides cracks me up!  I find them incredibly frustrating to use as well as the slightest tilt or the most invisible of objects (in the viewfinder at least!) always seems to ruin the shot.  The reason I love photography is for the challenges it requires so these are right up my alley.    Be prepared for some really lousy 11mm shots when I first get my 11-24 f/4, though ;D


I think my ultra wide shots are in a class by themselves, and probably would make your worst ones look wonderful by comparison.  I just do not have the ability to capture a beautiful panoramic scene that I see as a beautiful photo.  I think its a matter of practice and experimentation, but I've never found the time.  I intended to purchase a Nikon 14-24mm lens to go with my D800, but was turned off by some of the negative issues that pertained to my use so I never reached that point.

Since the price in Canada is generally quite a bit less right now, I'd try to get one in Canada.  Everyone in the US seems to have them in stock, so the Canadian stores should be getting large quantities soon.

Third Party Manufacturers / Re: Sigma 30mm F1.4 Art slow focus in liveview.
« on: February 24, 2015, 10:43:37 PM »
Third party lenses seem to struggle in live view as a general rule, its often mentioned in reviews.

The exception is in dual pixel cameras where live autofocus is not contrast detect.

Canon contrast detection as used in live view for standard sensors requires that the focus group move back and forth rapidly while the output is analyzed to determine the sharpest auto focus.  I'm guessing that the back and forth focus is slower and that slows down live AF. Another requirement is that aberrations must not interfere with the analysis software while the focus group is moving, perhaps another factor.

If I were using third party lenses on a crop camera in live view, I'd get a 70D or a 7D.

There are no dual pixel sensors for FF as of yet, so you have to suffer.

EOS Bodies - For Stills / Re: Upgrading firmware for 6D from 1.1.3
« on: February 24, 2015, 10:35:47 PM »
There is a section on CR describing the changes.

http://www.canonrumors.com/2014/12/canon-eos-6d-firmware-1-1-6-released/

I'd say its worthwhile.  The update came out 2-1/2 months ago and very few had issues after installing it.
