Tag Archives: Canon 40mm


A few days ago I received the latest Canon 40mm F/2.8 STM Pancake lens. The lens runs under $200 dollars on B&H (here) and delivers some stunning images. A little dark around the edges on full frame cameras, but it's very nice and lightweight for traveling photographers. A few people have commented about using it for video, and there's focus noise that you need to account for.

If you're shooting with an external audio recorder, or even a remote wireless LAV, you need not be concerned. I'm usually aware of in camera noise that gets picked up, especially when shooting with the loud Image Stabilization motors on the 24-105mm F/4L. The 40mm F/2.8 noise is heard in auto focus and even when the lens is switched to manual focus. If you're planning on using in camera audio, then check out video.




Received the new Canon 40mm F/2.8 STM pancake lens from B&H today. Wow, I really like it. Sure, it was made with their STM tech for full time auto focus in video mode for the new EOS T4i, but put all that aside, there's just no other options for Canon shooters who want a super low profile lens with auto focus.

I mounted the 40mm to the Canon 5D Mark III Full Frame camera, and you can see how the edges have a slight vignette (darker around edges). I personally like the look of this, and might consider this to be a more stylized lens for full frame cameras. If you want to have even exposure throughout the image, you can always program this lens into Adobe Lightroom's Lens Correction feature. On a T4i or other cropped cameras, you will see less of this vignetting.

It's too bad Canon doesn't have a smaller mirrorless body available (yet). As you can see from the image below, when placed on to the Canon T4i, the camera is about the same width as my Sony NEX-7 + Sigma 30mm (seen on the left). There's another example of how small this 40mm pancake lens looks on a Canon 5D (on the right).

The 40mm focal length is a good distance for this type of lens, and it was a focal range Canon was missing in their lineup. It's not too close and not too wide. It's lightweight, fast, and low profile to fit into small bags for traveling.

Rokinon 35mm vs Canon 40mm. Close focal distance, major size difference.

With a max aperture of F/2.8 it's not the fastest lens in Canon's line, but the build quality is great and the price is right at only $199. I highly suggest trying this lens out, and because it takes up minimal space in the bag, there's a good chance you'll want this with you all the time. They were out of stock on initial release, but are currently available via B&H (Click Here).

Just got news that the latest Canon 40mm F/2.8 STM lens will start shipping this Friday. For T4i owners, this STM lens is designed specifically for the Auto Focus feature of the T4i to be quiet and fast.

I did not opt in for any lenses when I purchased the Canon EOS T4i, but I should be this pancake lens next week to see how usable the Auto Focus is. I was testing out the Touch Screen focus feature on the T4i with my other L lenses, and it seems to be fairly accurate. This new 40mm is listed as an EF (not EF-S) so it should be a decent focal length for both Full Frame and APS-C cameras. Available for Pre-Order now.
