Roger Cicala of LensRentals tore down Canon’s new EF 35mm f/1.4 II lens.

[…] we’re impressed with the Canon 35mm f/1.4 Mk II. The weather resistance appears better than most weather resistant lenses. […] The mechanical construction is beyond impressive. This lens is massively over-engineered compared to any other prime we’ve ever disassembled. It’s built like a tank where it counts; on the inside. Moving parts are huge and robust. Six big screws are used in locations where 3 smalls screws are common in other lenses. Heavy roller bearings move the focusing group, it doesn’t slide on little nylon collars. Read the review (and see the many pics of the teardown)…

All this engineering wizardry comes with a price. The EF 35mm f/1.4 II is not a budget lens, selling at $1,799. But then, I guess this is part of the “you get what you pay for” category. The EF 35mm f/1.4 II features Blue Spectrum Refractive Optics, an optical technology developed by Canon that corrects chromatic aberrations at an extremely high level.

DPReview posted a Canon EF 35mm f/1.4 II review from a photojournalist’s perspective. The EF 35mm f/1.4 II is praised review after review and this one is not different when it comes to the optical qualities of this new Canon lens:

Putting this new lens on my camera has made me enjoy shooting at F1.4 more and, in turn, worry less about CA. Compared to the original 35mm F1.4 there are many advantages across the board. I really have nothing bad to say about the Mark II besides its hefty size, but that’s just the standard at this point for 35mm F1.4s, anyway.

With the inevitability of more high-megapixel bodies on the way, it is important to consider that you’re not necessarily buying a lens like the Mark II just for right now: you’re buying it for the future. With cameras like the 5DS R, older lenses – even L-series lenses – can mostly still deliver decent results, but the 35mm F1.4L II is a step up in terms of sharpness, color and CA control. If a high-megapixel body is something you’re considering in the future, you’re going to want to pick up this lens. Read the review…

Renowned lens testing site photozone.de felt the pulse of Canon’s new and highly acclaimed EF 35mm f/1.4L II lens. In the conclusion they write (emphasis mine):

The Canon EF 35mm f/1.4 USM L II is certainly an improvement over its predecessor but it’s not a new world wonder either. Resolution-wise it is tack sharp in the image center. At f/2-f/2.8 it is pushing the 50mp sensor of Canon EOS 5Ds R to its limits. However, the borders aren’t quite so hot especially at large apertures. To be fair though – at large aperture you don’t tend to require sharp corners anyway and unless you super-size your posters, it’s not that significant. Most users are also using full format cameras with a much lesser resolution. Still, we are seeing the limits of what’s possible today. Read the review…

Photography Blog posted their exhaustive review of Canon’s new EF 35mm f/1.4L II lens. The EF 35mm f/1.4L II is a highly regarded lens, well suited for travel photography and journalism. In the conclusion they write:

Image quality is outstanding. Chromatic aberrations are virtually non-existent thanks to the new Blue Spectrum Refractive Optics technology, geometric distortion is impressively low for a wide-angle lens, and the Sub-Wavelength Structure Coating (SWC) coatings successfully prevent contrast loss attributable to flare. The only real optical issues are some corner shading at the maximum aperture, something that every full-frame shooter has to put up with, especially when using wide angles, and a slight lack of critical edge sharpness between f/1.4-f/2.8 and f/16-f/22.

There is nothing not to like on the EF 35mm f/1.4L II, except for the price ($1,799). Beside the excellent build quality, the EF 35mm f/1.4L II is also a lens of a new generation, planned and build with Canon’s EOS 5Ds and EOS 5Ds R in mind.
