EF Mount for your iPhone 3 or iPhone 4
I was waiting, and waiting, and Photojojo finally did it. A lens mount adaptor for your EF lenses and the iPhone 3 & 4!
I love cool and unique “why the heck not” products. I hope to get my hands on one and adapt an EF 800 f/5.6L IS to it and go birding. That’s right…. birding with an iPhone!
The iPhone 4 version is $249 USD and the iPhone 3 version is $190. A steal for most photography accessories.

A new epic Zeiss
You can buy the new Zeiss 35 f/1.4 for Canon from B&H for $1843.00
You can also rent it from LensRentals.com for as little as $64.50 + shipping.
I’ve heard amazing things about this lens. The guys at LensRentals are crazy about it, or just crazy.

We previously reported Sigma would be updating some of their large primes.
[PR] via [EG] & have posted a patent for a new Sigma 500 f/4 supertelephoto lens.
With the price of the new Canon offerings, there’s going to be lots of room for other companies to make big glass more affordable.

![More Sigma Primes Coming? [CR1]](http://www.canonrumors.com/wp-content/themes/magnet/scripts/timthumb.php?src=http://www.canonrumors.com/wp-content/uploads/2011/03/2266_550_sigma_85.jpg&a=t&h=100&w=200)
Sigma adding to the prime lineup
With the success and quality of the Sigma 50 f/1.4 and 85 f/1.4, I’m told they’ll be adding more fast primes to the lineup over the next 18 months.
Lenses on the horizon may include a 24 f/1.4, 35 f/1.4 and 135 f/2.
Sigma will also continue to update lenses by adding OS to them. The 300 f/2.8 may be the first to get OS along with the 500 f/4.5. With the pricing of the new Canon lenses in these focal ranges, I wouldn’t be shocked to see Sigma do something 20% cheaper.

We’ve reported previously that certain Tamron lenses do not work fully with the Canon EOS 7D. The outer crosstype AF points do not work properly. It was discovered that Tamron used Lens ID’s that Canon no longer supported.
Canon made official what we already knew.
The following cameras are affected.

First reports of repaired lenses.
The first set of Tamron owners have received lenses back from Tamron correcting the cross-type sensor issue with certain Canon DSLR bodies.
The 17-50 f/2.8 VC was sent in and Tamron’s official statement for the fix was “autofocus adjustment”. This is a bit deceptive, what actually was done was a lens ID change from 37 to 137 (85 f/1.2L II lens ID).
Tamron Japan has not officially admitted that there is an issue. Perhaps this is being done to avoid a mass recall of lenses.
Cost of repair?
For the moment, the lens ID switch is covered under the standard warranty. No word on out of warranty products yet.

What’s coming from Zeiss?
Zeiss will introduce some zooms in 2011 for ZE (Canon) and ZF (Nikon). None of the zooms will go longer than 200mm.
A longer Zeiss prime in the 135mm range will also be announced.
Zeiss 35 f/1.4
Initial reports I’ve received say the lens is awesome. I cannot wait to try it out.

UPDATE #2
New Information about that phenomenon, which is not just a Tamron phenomenon anymore. A guy at the DSLR-forum replaced the Lens-IDs with an EF adapter and found out that the cross-type sensors won’t work on Lenses with the following IDs: 27, 30, 35, 37, 38, 193, 194, 195).
So Tamron was just unlucky by taking the wrong IDs.
The following Canon lenses are also affected:

thanks Jorg
UPDATE
The Tamron 70-200 f/2.8 is also confirmed to have the issue with the 40D, 50D and 7D outer focus points not being crosstype.
7D Affected
A few days ago we reported some Tamron lenses weren’t using the outer crosstype sensors on the Canon 50D.
Tamron Europe has confirmed the Canon 7D and Tamron 17-50 f/2.8 VC also exhibit the same issue.
We’re still waiting for an official response from Tamron in Japan.

Interesting issue with Tamron Lenses
I received this information a while back, I didn’t post it until there was some kind of response from Tamron.
The following is a direct quote from the folks that found the problem. Tamron’s response is at the bottom.
i am a member of the german dslr-forum (www.dslr-forum.de), which is probably the biggest german speaking community regarding all DSLR-topics (not only Canon). We observed a phenomenon where the followings lenses won’t use the outer cross-type sensors of EOS 40/50/60/7D cameras right.
The lenses that show this problem are (all Tamron):
To get a bit more into the detail of the problem – on the 40/50/60D cameras the outer cross-type sensors only work as line-type sensors. To be a bit more correct, they actually work in the same direction as they would work on cams like the 30D or like the 400/450/500/550D. When it comes to the 7D the outer sensors are also only working as line-type sensors (but it seems, that the EF 50 1.2L also has problems to use them correct).
The center cross-type sensor does work at least as a single-cross type sensor (infact we don’t now how to test if the center sensor is working as a dual-cross-type sensor like it’s supposed to work with those f/2.8 and better lenses).
Tamron seems to not know about this behaviour so far. Well – at least, they didn’t confirmed the problem and only said, that they will investigate this.
Maybe a small addition – the Tamron 17-50 VC uses the same lens-ID as the EF 35-80 – maybe you’ll have the chance to check whether this Canon-lens performs correctly or not.

Tamron Europe’s Official Response
Dear Mr. S.,
we were able to reproduce the situation where the Tamron 17-50 VC (B005) and the Tamron 60 Macro (G005) won’t use the Canon EOS 50D cross-type sensors correctly.
We have given this information to Tamron in Japan and we are expect an answer very soon.
Best regards
Tamron Europe GmbH
Thanks Joerg

Update
