Lenses / Patent: 600 f/4 DO IS & 400 f/2.8 DO IS
« on: May 22, 2012, 08:07:42 PM »
Patent Time!
More diffractive optic patents from Canon. This time, another 600 f/4 IS DO lens and a 400 f/2.8 DO IS.

With the cost of the new super telephotos from Canon, I can’t imagine what new DO lenses would cost.

Lenses / Canon EF 40mm f/2.8 Pancake Coming [CR3]
« on: May 21, 2012, 08:44:26 PM »
It’s coming
We reported this a long time ago, it’s good to hear about it again. There will be an inexpensive “pancake” lens coming to the Canon lineup.  It will be  an EF 40mm f/2.8, non L lens. How much? I’m told less than $300 USD.

For those that don’t know, a pancake lens is a very thin, small and light lens. It could be fun mounted to the front of a 5D3 or a smaller Rebel.

Expect it to be announced in June with the T4i and a new EF-S 18-135 IS II.

A couple people have written in to inform me that their Canon GP-E2 have been listed as “shipped” from B&H. The GP-E2 is the hot-shoe and/or GPS accessory for the 1D X, 5D Mark III and 7D (USB only).

The GP-E2 is $269 at B&H

EOS Bodies / Canon EOS 70D & EOS 7D Mark II Speculation [CR1]
« on: May 21, 2012, 12:12:11 PM »
APS-C replacements soon?
The first of what will probably be many spec lists about the mentioned cameras. With the knowledge of an 18mp T4i, it stands to reason that Canon will retain the same megapixel count in the next xxD and xD APS-C cameras. Still no mention whether or not it’s an updated sensor. I would certainly hope it is.

EOS 70D

  • Digic 5
  • 18mp
  • 100% viewfinder with grid lines like 7D
  • 19 AF Points from 7D
  • Continuous AF in LiveView & Video Recording
  • September Announcement

7D Mark II

  • Dual Digic 5
  • 100% viewfinder
  • 61 Point AF from 5D Mark III
  • Announced after 70D

This is a grain of salt spec list, though I do think anything announced for Photokina would be mostly finalized by now.

Canon General / Official Discontinued List
« on: May 21, 2012, 10:05:39 AM »
Say bye!
The following products have been officially discontinued by Canon, so if you find them in stock anywhere, the time is now.

The 580EX II is highly recommended, I rent a lot of them and they’ve been bulletproof.

Everything on this list has been replaced by newer, and more expensive versions. The EF 24 f/2.8 IS, EF 28 f/2.8 IS and EF 24-70 f/2.8L II have not begun shipping yet, and we’re hearing July 2012 at the earliest. The Speedlite 600EX-RT has begun shipping in pretty good quantities.

Canon EOS-1D X

As of the end of last week, Canon is still holding to the end of June for shipments to begin. That’s what is still being told to a couple of large retailers.


Canon EOS-1D X at B&H $6799


Canon EF 500 f/4L IS II & EF 600 f/4L IS II

These two lenses are proving to be more elusive to nail down. Current Canon says they’re begin shipping in May, however 2 retailers I spoke to have said they’re now being told the end of June to the beginning of July for availability.


If any of this changes (and it probably will), I will update.

New stuff to read

I have posted a couple new articles from one regular guest at Canon Rumors, Roger Cicala from LensRentals.com and a new article from the good people at Creative Pro.


 


A History Lesson: Exploding Photographers, Disappearing Clothes, and the Development of Film

Roger Cicala has done history articles in the past, and I’ll be honest, they’re about the only ones I read top to bottom. So if you like photography history, check the article out.

EOS Bodies / Canon BG-E11 Making its Way to Retailers
« on: May 18, 2012, 03:09:18 PM »

Finally!
We’ve had spottings of the BG-E11 showing up in Australia and the UK. They should make their way around the rest of the planet fairly quickly. I’m told we’ll be able to get them in Canada next week, I assume it’s the same in the United States.

Proof! From @iSimonDavis in the UK

EOS Bodies / Canon to Announce 2 Cameras in June [CR2]
« on: May 16, 2012, 08:43:00 AM »
June is the month
Received information from various places that Canon will announce 2 new cameras in June (not including PowerShot updates).

One camera will be an EOS (650D) and the other will be a mirrorless entry.

I’m sure we’re going to start seeing more information in the coming weeks. I also expect Canon to spend a bit of marketing dollars on a mirrorless camera. Maybe we’ll see some teasers.
