« on: July 10, 2012, 08:05:58 AM »
From the Czech Republic
Invites for the July 23, 2012 product announcement date seem to be making their way around to folks.

It’s suspected this is when we will see the announcement of Canon’s first mirrorless interchangeable lens camera. We may finally get the official announcement for the EF 200-400 f/4L IS 1.4x lens as well.

Lenses / Patent - Canon EF 24-70 f/2.8L IS
« on: July 08, 2012, 05:48:06 PM »
You want IS?
A patent for an EF 24-70 f/2.8L IS has surfaced finally, this has been a lens that has been talked about and desired for a long time.

We mentioned some time back that there were 5 or 6 version of the new 24-70, and one of them had IS. Canon decided against an IS version for reasons to do with weight, size and cost from what I’m told.

Sadly for the ones that want an IS version of this lens, I have little faith that such a lens will be coming any time soon. Patents can sometimes appear after a product has been announced, and that’s probably what has happened here.

EOS Bodies - For Stills / Canon Rebel T4i/650D Tear Down
« on: July 07, 2012, 09:34:26 AM »
A look inside the Rebel T4i
The folks at Chipworks have torn apart a Canon EOS Rebel T4i/650D to take a look inside. There’s some good explanation about phase detection autofocus as well as a list of the manufacturers used inside the camera.

About Phase Detection Autofocus

Phase detection is where there are pairs of sensors that are blocked left and right (or top and bottom) and from the differences, the camera has the information needed to bring the image into focus. Please remember that teardown articles are generally focused on preliminary analysis because that is all we have at the time of publication (our Technology Blog focuses more on hard facts about the chips). With that in mind, we can see that unlike the Aptina sensor Canon is using a somewhat irregular pixel pattern for phase detection versus Aptina that used a set of regular lines. Our full report will include key information like SEM and bevel analysis to show the implementation in more detail and at higher magnification.

Lenses / A New EF 50 f/1.8 IS? [CR1]
« on: July 07, 2012, 09:09:49 AM »
A new 50?
A purported replacement to the EF 50 f/1.4 was mentioned today in the form of an EF 50 f/1.8 IS. The lens would be smaller than the current 50 f/1.4. There is no imminent announcement of such a lens, but Canon is working to replace the 50 f/1.4 sometime in the next year. The current 50 f/1.8 would remain in the lineup.

CR’s Take
There’s no doubt in my mind Canon is working on a couple of new 50mm lenses. With IS added to the new 24 & 28mm primes, IS in a 50 shouldn’t surprise anyone. It would be a welcomed lens if they can make it small enough to work well on a mirrorless platform.

Take this one with a grain of salt….


EOS Bodies / Issues with Stock of the EF-S 18-135 IS STM?
« on: July 07, 2012, 09:00:30 AM »
EF-S 18-135 IS STM Delay?
We’ve received a couple of reports from readers that their orders for the Rebel T4i w/18-135 IS STM kit have been cancelled without much reason given. One of the retailers cancelling the preorder was Amazon.

We’re waiting to hear some clarification on the matter. If your order has been cancelled, please let us know.


EOS Bodies - For Stills / Canon EOS Rebel T4i/650D Service Advisory
« on: July 05, 2012, 10:26:29 PM »
Here we go again…
Thank you for using Canon products.

The front rubber grips of some units of the Canon EOS REBEL T4i Digital SLR camera (EOS 650D/EOS Kiss X6i overseas models) may change color (turn white) after a short period of time. Customer support for this phenomenon is described below.

Canon continuously strives to provide our customers with high quality, reliable products that can be used with confidence. We offer our sincerest apologies to any customers who may be inconvenienced.

The front rubber grips of some EOS REBEL T4i units produced in certain lots during the sixteen-day period between May 31st through June 15th, 2012 may turn white after a short period of time. We have determined after inquiry with the rubber manufacturer and analysis, that the substance zinc bis (N,N’-dimethyldithiocarbamate) is what causes the rubber surface to turn white.

Zinc bis is not used in the production of this product. However, the quantity of rubber accelerator used in the affected production lots was slightly higher than usual. As a result the rubber grips may turn white due to a chemical reaction with the rubber accelerator and other substances. High temperature and high humidity may contribute to this condition. Zinc bis (N,N’-dimethyldithiocarbamate), which becomes deposited on the rubber surface, is created as a result of this chemical reaction.

Affected Product
Some EOS Rebel T4i digital SLR cameras produced from May 31 through June 15 may be affected.

You can use the serial number to check whether your camera is affected by this phenomenon. If the sixth digit of the serial number is “1″ please follow the procedure below. If the sixth digit of the serial number is “2″ or higher, your camera is not affected.

1) Click on the link below to enter your serial number.

2) Enter the 12-digit serial number (reference the image below) from your camera then click the Submit button

3) One of the following messages will appear.

· “Your camera is NOT affected” ? No further action is required

· “Your camera is affected” ? Please see the Support section below

Click here to enter your serial number (hint: read this instruction before opening that page)

Caution on Use
The amount of zinc bis (N,N’-dimethyldithiocarbamate) detected during our testing was minimal. While Canon has not received any reports of injury or allergic reactions, depending on one’s health and physical condition, in rare cases when this substance comes into contact with skin, allergic skin reactions* may develop. In addition, if eyes are rubbed after contact with the substance, symptoms, such as red eyes, may develop.

As a precautionary measure, thoroughly wash your hands with water if they have come in contact with the rubber grips that have turned white. (If any medical symptoms develop, please consult your physician immediately.)

*Please note that the occurrence of allergic skin reactions depend on the target substance, length of contact with the target substance, one’s health and physical conditions, and sensitivity of one’s skin structure, and not everyone will be affected by allergic symptoms.

Preparations are underway to provide free repair service for affected cameras by replacement of the rubber grips. Once this repair service is available (ETA of mid July 2012), we will post an update on our web site and also notify registered users via email. Please register your EOS Rebel T4i, so that we can inform you via email when the free repair service will commence.

This information is for residents of the United States and Puerto Rico only. If you do not reside in the USA or Puerto Rico, please contact the Canon Customer Support Center in your region.

Thank you, Customer Support Operations

Lenses / Canon EF 24-70 f/2.8L II Delayed Again
« on: July 05, 2012, 09:34:48 AM »
Not good news
Contrary to what I was told recently by a few retailers, Canon has delayed the release of the EF 24-70 f/2.8L II again. This time until mid September 2012. The reason for the delay is said to be for “final  adjustments in production”.

CR’s Take
This is tough news for a lot of people. I own a lens rental business and not being able to find more new 24-70′s in Canada to add to stock has caused a few moments of stress. We were really hoping for a smooth switchover from version 1 to version 2.

However, if this is for quality control reasons, then the delay is worth it. No matter how much it drives us bonkers.

EOS Bodies - For Stills / My Canon EOS-1D X Has Arrived!
« on: July 04, 2012, 09:39:13 AM »
Finally eh?
My Canon EOS-1D X has finally arrived! I think I actually preordered it before it was announced.

First Impressions?
Not many yet. I have touched this camera countless times at various photography trade shows, so nothing is really new. It is really nice to actually be able to put a card into one of the slots and save some images.

I will be using this camera pretty hard for the next little while and will let you know what I think.

Availability in the United States should come on Thursday or Friday, I’ve confirmed this with B&H.

They’re coming!
We have unconfirmed reports that a few retailers in the US and Canada will be receiving their initial Canon EOS-1D X shipments this week.

We have reports they’ve shown up already in Montreal, Canada. I expect to get mine some time this week.

B&H Photo
We can’t confirm, but we’ve heard B&H Photo has told preorder customers that they expect a shipment this week. The July 4, 2012 holiday may disrupt some shipping though.

EOS Bodies / Canon Mirrorless Information [CR1]
« on: July 02, 2012, 10:59:42 AM »
A bit of information
With Canon’s expected foray into the mirrorless segment just around the corner, a bit more information has started to flow.

We’re told the new camera is in fact a new mount, I think most expected this. The camera will launch with at least 2 lenses and an EF adaptor. One lens will be a wide angle “kit” lens as well as a telephoto lens.

No word on whether or not the EF adaptor would also adapt EF-S lenses, though I would hope it did.

It is also suggested that the new primes that Canon has announced and released (24, 28, & 40mm) are the first in a series of small prime lenses meant to work well with EOS EF and the mirrorless camera.

Information about the body itself is pretty vague. It’s still suggested the camera will use the 14mp CMOS G1 X sensor. A “good” ISO range and “average” video performance. A video focused camera could be “in the future”.

EF Lens Adaptor
We have posted a couple of patents in the past about such an adaptor. You can view them here and here.

Northlight has posted a cool little diagram showing the size of the EF adaptor in comparison to the new EF 40 f/2.8 pancake.
