has the Sigma 150-600mm f/5-6.3 DG OS HSM Sports Lens
available for preorder. The price – $1,999.00 with free shipping.
This price point makes the new Sigma lens about twice as expensive as the Tamron 150-600mm f/5-6.3 Di VC USD
. It'll be interesting to see how the two lenses compare.

In case you didn't notice, the Tamron 150-600mm f/5-6.3 Di VC USD Lens
is currently sitting at the top of the "Most Popular Lens" leaderboard (on the home page
). Impressive image quality from a very long focal length zoom lens with a very reasonable price has driven the 150-600 VC's popularity.
The lens has become so popular that finding one in stock has become a challenge. Amazon
states "Usually ships within 1 to 3 months" for this model. The 150-600 VC is available on eBay
, but be prepared to pay a premium for it. That this lens has become difficult to find has led to theories that Tamron pulled the lens from shelves or stopped production of the lens to address a deficiency. The other report I'm receiving is that the latest models of this lens are autofocusing more accurately than the early models. (thanks Chris)
To clear things up, I contacted my Tamron rep. What I learned is that the firmware installed on this lens has indeed been updated; starting with models produced in May 2014. The firmware update was specific to the Canon-mount version and was designed to improve autofocus performance. Unless a dealer is sitting on old inventory, all lenses currently being shipped should have the updated firmware. Lenses with the original firmware can be sent to Tamron for the update.
The other clarification that I received was that unavailability of this lens is entirely due to demand exceeding supply. There have been no halts to production and no recalls issued.
If you want to add a Tamron 150-600mm VC Lens
to your kit, preorder
and be patient.

available for $2,899.99 with free shipping. Compare at $3,799.00 after $200.00 mail-in rebate. (thanks Chuck) Note:
This is likely a grey market item and not technically eligible for a Canon USA warranty.

COLOGNE, Germany – Beefing up its telephoto lens line, Canon plans to revamp an aging 100-400mm zoom and bring a novel technology called diffractive optics to more models.
Lenses are key to camera company profits: the more lenses a photographer has, the harder it is to move to a rival's system of camera bodies and lenses. And unlike camera bodies, lenses don't go out of date so fast, which means they're more profitable to sell once investments in engineering and manufacturing are paid off.
The 100-400mm zoom is a good example. Canon introduced it in 1998 with its first-generation image stablization technology, which counteracts some camera shake, and still sells it for $1,700. But a new model is in the works, said Canon technical advisor Chuck Westfall in an interview here at the Photokina show Monday. "It's definitely on the boards for replacement," he said, though declining to say when.
In addition, Canon is working to spread a technology called diffractive optics, or DO, into more lenses, he added – maybe even cheaper lenses..."

Bryan has updated the newly announced Canon lenses' placeholder pages with MTF chart comparisons. All three lenses look pretty good compared to older and/or similar lenses. Alternate product views have also been added.
