Lenses / Re: EF-S 17-55mm f/2.8 Going Away?
« on: Today at 01:18:46 PM »
I suspect that its going to be there for a long time.  Shortages are starting to hit due to the West Coast dock strike, so Canon may pull buy it now links.

Canon General / RIP Leonard Nimoy
« on: Today at 01:11:45 PM »
Leonard Nimoy passed away today.

Besides being in Star Trek, he was a photographer as well.  I was privileged to be one of those who watched the Star Trek series when it first came out in the 1960's. 

"Nimoy had other roles during a long career in TV, film and theater, and directed successful movies, wrote books, composed poetry, published photographs and recorded music."

A Local incident where a Drone was, in the Opinion of the rescuers interfering.

http://www.khq.com/story/28215396/drone-interferes-with-rescue

There was probably no way for the drone operator to know he was causing a issue, and no way for the Rescuers to contact the operator to ask him to stop interfering.

This type of incident hurts all those who are careful and inspires the creation of new laws.

PowerShot / Re: Advice for non-compact versatile camera plz

You can get a very good DSLR for less than a SX60.  The SX60 has not really garnered much in the way of positive comments from those who have a SX50.  A refurb SX50 can often be found for under $200.

If she is wanting a small camera, a G1X refurb is going to blow away the IQ of a SX50 or 60 (I have both).  My SX50 is strictly for long telephoto objects when I can't use my DSLR.  Its just OK.  My G1X is excellent.

There are some low cost EOS-M cameras available as well.  They are smaller than a DSLR, but have the large sensor.

Canon General / Re: Lens stuck on the dock in California

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.



"CLAIMS

 [Claim(s)]
 [Claim 1]

 [Claim 5]
 The photoelectric conversion device according to claim 3 or 4 having an adder unit for adding a signal of said first photoelectric conversion part and said 3rd photoelectric conversion part.
 [Claim 6]
 A photoelectric conversion device of a description in any 1 item of Claims 3-5 having an amplifier control part which controls an amplification factor of an output signal of said first photoelectric conversion part and said 3rd photoelectric conversion part based on an output signal of said second photoelectric conversion part.
 [Claim 7]
 A photoelectric conversion device of a description in any 1 item of Claims 3-6 having a storage time control part which controls charge storage time of said first photoelectric conversion part and said 3rd photoelectric conversion part based on an output signal of said second photoelectric conversion part.
 [Claim 8]
 A photoelectric conversion device of a description in any 1 item of Claims 1-7 having the amplifier which outputs a signal which carried out time quadrature of the current which fixes electric potential of said second photoelectric conversion part, and is outputted from said second photoelectric conversion part.
 [Claim 9]
 A focus detecting device carrying out two or more owners of the photoelectric conversion device of a description to any 1 item of Claims 1-8.
 [Claim 10]
 The focus detecting device according to claim 9,
 It has a lens which images an optical image,
 An imaging system driving the aforementioned lens according to an output signal of the aforementioned focus detecting device.
 [Claim 11]
 A first photoelectric conversion part formed with the 1st conductivity type of a semiconductor substrate,
 It is a drive method of a photoelectric conversion device which has the second photoelectric conversion part which was formed in a position deeper than said first photoelectric conversion part to a depth direction of the aforementioned semiconductor substrate, and was formed with the 2nd conductivity type,
 A drive method of a photoelectric conversion device characterized by controlling charge storage time of another side according to a signal based on either said first photoelectric conversion part or said second photoelectric conversion parts."

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.

EOS Bodies / Re: Smartphones Already Won -- Laforet

"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.
