As if a new full-frame mirrorless camera system, four lenses, and three adapters weren’t enough, Canon threw in three more goodies: two updated super-telephoto DSLR lenses and the fastest EF-M lens to date. Canon announced a trio of new lenses on Wednesday, Sept. 5, including the new EF 400mm f/2.8L IS III USM, EF 600mm f/4L IS III USM, and for the EOS-M mirrorless line, the EF-M 32mm f/1.4 STM. While weight loss in new lenses is typically measured in ounces, Canon managed to shave off pounds from the high-end DSLR lenses, which the company says makes both lenses the lightest in the respective focal lengths yet. The 32mm, on the other hand, has the widest aperture yet for EOS-M glass.
On the outside, the third-generation 400mm F/2.8 and 600mm F/4 lenses look absolutely identical to their predecessors, aside from a slightly different nameplate. In fact, it’s not until you pick up the two lenses that you notice the difference. But when you do pick up the lens — wow. Having shot with the Mark II version of both the 400mm F/2.8, we know how heavy they are to lug around.
Somehow, Canon managed to drop the weight of both of the lenses while also adding new features. The Mark III version of the 400mm F/2.8 lens slimmed down by 2.2 lbs, while the 600mm F/4 shed 1.9 lbs, a reduction in more than 25 and 20 percent, respectively.
Aside from the weight reduction, both the Canon EF 400mm F/2.8 L IS III and EF 600mm F/4 L IS III USM also feature an improved image stabilization module that bumps it up to five stops of correction compared to the three-and-a-half stops in the lenses respective predecessors. New electronic focus rings, nine-blade aperture diaphragms, and fluorine coatings help round out the updated lenses.
The Canon EF 400mm F/2.8 L IS III USM and Canon EF 600mm F/4 L IS III USM are due out December 2018 for an MSRP of $11,999 and $12,999, respectively.
At the request of photographers from around the world, Canon has released a new EF-M 32mm F/1.4 STM prime lens for its M-series mirrorless cameras, showing that its APS-C mirrorless system might not be as dead as some have thought.
The new lens is constructed of 14 elements in 8 groups, including a glass molded aspherical lens. Its stepping motor (STM) offers smooth, quiet focusing, making it a great option for shooting video. The 32mm focal length is equivalent to roughly 51mm on a full-frame camera — a great standard focal length for almost any type of photography you can throw its way.
The EF-M 32mm F/1.4 STM will be available September 2018 for about $480.
Full-frame cameras tend to be chunky beasts, but Sigma wants to prove that big imaging doesn't need a big body. Enter the Sigma FP2, the successor to its tiny, boxy fp mirrorless camera. It keeps the same modular design but packs in some serious upgrades, including a 24.5-megapixel partially stacked full-frame sensor, improved autofocus, 6K video recording, and 70GB of built-in storage. Sigma calls it the world's smallest full-frame camera, and while it might be tiny, the same cannot be said for its price tag.

A phone thermal camera is one of those tools you don’t think you need until the first time it saves you from an expensive problem, and the Thermal Master P3 just got easier to try. For Halloween, it’s discounted with the code THERMCAM10, a 10% cut that works out to $107 off the total. It’s also fresh off a win at the 2026 Tom’s Guide AI Awards for best phone thermal camera, which is the kind of third-party nod that separates a serious tool from the cheap clip-on sensors that flood this category.
We are nearing Amazon's Prime Big Deal Days, which officially run October 6 and 7. But there is no need to wait until the sale begins to start looking. Early offers are already live, and camera gear is one category where I found enough worthwhile discounts to put together a proper creator-focused list.
I’ve deliberately gone wider than interchangeable-lens cameras here. There are pocket and action cameras, a 360 camera, an instant camera, two wireless microphone systems, and a pair of webcams covering very different budgets. Prices were checked on October 2, and as always with Amazon, they can move quickly.
