Patent: Canon EF 600 f/4L IS III & EF 600 f/4 DO IS

Patent: Canon EF 600 f/4L IS III & EF 600 f/4 DO IS

A new patent showing the 600mm f/4 optical formula. Is Canon already working on the replacements to the current super telephoto lenses? It’s quite possible! Although I suspect we’re talking 7-10 years from now. These sort of patents could also be for technology that will appear in  other lenses. Such as the upcoming replacement of the EF 800mm f/5.6L IS.

I do expect we’ll be seeing more DO lenses in the future. There seems to be an awful lot of patents for DO optical formulas. I suspect the cost of production is the hinderance to bringing these lenses to market at the present time. We already have $11,000 200-400 f/4 lenses and $18,000 800mm lenses. I suspect we’re at the ceiling of what people will pay for a lens…. or not. :)

Canon has released a firmware update for EF300mm f/2.8L IS II USM, EF400mm F2.8L IS II USM, EF500mm f/4L IS II USM and EF600mm f/4L IS II USM lenses. This firmware update will be performed by Canon Service Centers. Please contact us using the contact information listed at the bottom of this page.

Firmware changes:
Firmware Version 1.1.1 incorporates the following enhancement:

1. Changes the control algorithm of the focus drive, and enhances the drive’s responsiveness for more precise focus and adjustments. In particular, the new firmware enhances the AI servo AF capability of the lenses to track objects that move irregularly in sports events, such as soccer or rugby.

Affected Products:
Firmware Version 1.1.1 is for lenses with Firmware Version 1.0.0. If the lens’ firmware is already Version 1.1.1, it is not necessary to update the firmware. The serial numbers (10 digits) of the lenses equipped with Firmware Version 1.0.0 are as follows:

EF300mm f/2.8L IS II USM:
The third digit in the serial number is either 0, 1, 2, or 3 (xx0xxxxxxx, xx1xxxxxxx, xx2xxxxxxx, xx3xxxxxxx).

EF400mm f/2.8L IS II USM:
The third digit in the serial number is either 0, 1, 2, or 3 (xx0xxxxxxx, xx1xxxxxxx, xx2xxxxxxx, xx3xxxxxxx).

Canon EF 600 f/4L IS II Review

Canon EF 600 f/4L IS II Review

A great Canon EF 600 f/4L IS II field review
Arash Hazeghi has posted a review on his blog for the new EF 600 f/4L IS II super telephoto lens. It’s a terrific review with wonderful photographs, much better than the one we did ever so quickly. If you’re into bird photography, definitely check this review out.

Conclusion

….Especially given the fact that the EF 600mm f/4L IS II is the sharpest, fastest and lightest 600mm super-telephoto lens currently on the market that eclipses the competition. At the end of the day, value for money is a relative figure. For handhold photographers who desire to produce top notch flight images, the EF 600mm f/4L IS II can significantly increase field productivity making it the best option on the market for this group of photographers. After spending just two weeks with the lens, I can state with confidence that the EF 600mm f/4L IS II is the most impressive product from Canon I have used to date and I am not easy to impress, therefore, highly recommended!

First Impression – Canon EF 600 f/4L IS II

First Impression – Canon EF 600 f/4L IS II

What do we think?
I have posted our initial impressions of the new Canon EF 600 f/4L IS II. My professional outdoor photographer friend Ethan Meleg took the lens for a day to see how it performed.

Visit Ethan on Twitter | Facebook | Blog

As with all reviews at Canon Rumors, there’s absolutely no technical stuff. We just try to tell you what we think about it in real world situations. There will be lots of pixel peeping coming in the near future I’m sure from the sites that do it great.

We’ll update the review in the coming months, we just haven’t had enough time to put it through all the various situations we might use a 600mm lens for.

Rebates & BG-E11 Shipping Updates

Canon Rebates Extended
The Canon rebate program that was set to expire at the end of May has been extended until the end of June. This is the double up savings program if you buy a camera body along with a lens. There are also instant rebates on lens purchases only.

The 5D Mark III isn’t found in stock in too many places, so at least you get an extra month if you’ve been waiting to take advantage of the rebate when buying a 5D3.

Click to go

Visit B&H for the rebate portal.

BG-E11 Shipping Everywhere
I’ve received notifications that B&H and Adorama have begun shipping the BG-E11 to preorder customers.

Sigma Lens Rebates
Sigma has rebates going on until July 31, 2012. Visit B&H for more.

Canon EF 500 f/4L IS II & EF 600 f/4L IS II Availability
Various smaller retailers have received lenses. I know of a couple of 500′s that appeared in Toronto, and I received my 600 today.

I know B&H is expecting a shipment this week, however there is a preorder wait list. They expect the first 2 shipments to cover what is already preordered. I am unsure about the status with Adorama.

B&H: 500 f/4L IS II | 600 f/4L IS II Adorama: EF 500 f/4L IS II | EF 600 f/4L IS II

If you’re a retailer and get a 500 or 600 in stock that isn’t spoken for, please let me know and I can let the readers of CR know.

5D Mark III Stock
Stock of the 5D Mark III is low at the moment. Shipments for the camera should start arriving near the end of this week. I’m waiting to hear from the large retailers.
