Canon 17-40mm L f4 vs. Tokina 17-35mm f4 - head to head test

Feb 5, 2012

Hello,

Having recently upgraded to 5D mk II, I have been looking closely at the available options for an ultra wide angle zoom. I was pleased with the performance of the Tokina 11-16mm and 12-24mm lenses on my Nikon D90, so I thought it would be interesting to do a head-to-head test of the native Canon 17-40mm L f4 vs. the new Tokina 17-35mm f4 lens on my 5D mk II.

A few disclosures before getting into the results:

1. I bought and tested 4 different copies of the Canon 17-40mm lens and tested them extensively against one another. 2 of the 4 performed better than the others and very closely to one another. One of these was used to test against the Tokina lens.

2. Only one copy of the Tokina lens was tested.

3. A total of 120 shots between the Canon and Tokina were compared at 100% on a 24” color calibrated monitor. The shots consisted of three different urban scenes, using center AF point, tripod mounted, remote shutter release, and mirror lockup. Central focus target was > 10m away for all three scenes.

Results:

Sharpness:

17mm: f4 – Tokina slightly sharper centrally and moderately sharper in corners* f5.6 – very similar, center equal, Tokina slightly sharper in corners* f8 – very similar, center equal, Tokina slightly sharper in corners* f11 – very similar, peak performance at this focal length for both

24mm: f4 – Tokina soft / low contrast throughout, Canon markedly sharper f5.6 – Tokina soft / low contrast throughout, Canon markedly sharper f8 – Canon noticeably sharper but Tokina catching up f11 – very similar, peak performance at this focal length for both

28mm: f4 – Tokina soft / low contrast throughout, Canon markedly sharper f5.6 – Tokina soft / low contrast throughout, Canon markedly sharper f8 – Canon noticeably sharper but Tokina catching up f11 – very similar, peak performance at this focal length for both

35mm: f4 – Tokina soft / low contrast throughout, Canon markedly sharper f5.6 – Tokina soft / low contrast throughout, Canon markedly sharper f8 – Canon noticeably sharper but Tokina catching up f11 – Canon noticeably sharper throughout, peak performance for both

Chromatic aberrations:

Canon: mild wide open at image edges, resolved by f5.6-8 depending on focal length.

Tokina: severe at all apertures and focal lengths, though decreasing as you stop down. At 17mm the Tokina may have the resolution advantage at f4-f9 at the borders and corners, but it’s almost negated by aberrations.

Flare:

Not tested.

Build quality / handling:

Tokina is moderately but noticeably heavier mounted on a 5D body (600g vs 475g), and has a bit more girth (82mm filter size vs 77mm, chunkier overall). Zoom ring has high resistance like other Tokina wide angle lenses. Zoom direction is opposite of Canon convention (a la Nikon). Both are well built.

Overall:

The Tokina slightly outperforms the Canon at 17mm and f4, but the advantage is tempered by very high chromatic aberrations on the part of the Tokina. The sharpness advantage for the Tokina goes away as you stop down at 17mm; by f11 the two lenses perform very similarly in terms of resolution. In fact, peak performance for both lenses is around f11 at all focal lengths, where the Tokina is unfortunately still displaying significant CAs. The Tokina has very low contrast and sharpness throughout the frame at 24mm, 28mm, and 35mm at f4 through f8. It catches up to the Canon by f11 at 24mm and 28mm, but the Canon is still noticeably sharper at 35mm at all tested apertures throughout the frame.

I would say that for my intended purposes (landscape, urban photography, travel) the Canon has demonstrated consistently better optical properties. The CAs on the Tokina, while fixable in PP, can be complex and difficult to edit out, and detract from the overall subjective quality of the image. In addition I found the build and handling of the Canon lens to be more pleasing.

On the other hand, I did have to test several copies to find a great performing Canon sample. Perhaps the results for the Tokina could have been better if I had tested multiple samples but I just didn’t have the stamina for it! Having seen other examples of the low contrast and sharpness at the longer end of the range for the Tokina, and its symmetric nature across the frame, I have to think these qualities of the Tokina are no fluke.

(From Tokina lens literature) The Tokina AT-X SD 17-35mm F4 PRO FX is a compact, high performance wide-angle zoom lens for digital SLR cameras with full frame support. The lens features the company's newly developed SD-M (Silent Drive-Module) AF system for precise and quiet autofocus, and is weather-sealed.

It is not pixel peeper tack sharp wide open competes with a lot of the other lenses in this category. The price/value proposition is great.

• 9 out of 10 pointsand recommended by NickTrop (5 reviews) Cost, Build Quality, Size, Sharpness Stopped Down, Very Low Distortion Sharpness wide open Know what? If you don't want to blow a wad of cash on a wide angle zoom, this is your lens. This is a landscape lens or used to shoot interiors with a Speedlight. I always shoot such lenses mounted on a tripod, stopped down to f8, f11 where they're all about the same in terms of resolution. This is a special purpose, not a general purpose lens -- no need for speed in such a lens, therefore no need to spend three times as much for one if you're stopping it down to f8, f11 anyway and mounting it on a tripod to shoot a landscape or real estate interiors. Well-made as are all Tokinas. This Tokina also boasts impressively low distortion for its type. Build-quality belies it's comparatively low cost, and because it's a sensible (for such a lens) f4, it is smaller and lighter than most other FX wide angle zooms. A sensible, budget-friendly choice for its intended purpose. reviewed June 8th, 2018 (purchased for $399)

Value Handling

Edge softness at 17mm and 35mm at f4

I have only recently purchased this lens to use on my Canon 6D. I had, loved and sold the Canon 16-35mm F4 IS lens due to lack of use, ( I found it hard to justify having a $1349 AUD lens just sitting there as I don't work). So I sold it and purchased this lens as an ex demo from an Australian store for $220 AUD. I carried out some basic tests with an ISO test chart and was pleasantly surprised.

I found that the lens was quite soft in the corners at 17mm at f4 and still soft at 5.6, but quite reasonable at f8. At 21mm the lens is soft in the corners at f4 but at 5.6 it is good and at f8 sharp across the frame and at all focal lens f8 is the sharpest by some margin, with f5.6 from 21mm to 28mm good to very good across the frame. At 35mm the lens is again quite soft in the corners at f4 and gets to be good across the frame at f8. The lens is at it's sharpest around 21mm, with 24 to 28mm not far behind. 35mm appears to be the lenses weakest focal length.

Overall I think this lens represents good value at it's retail price of around $600 to $700 anything less than that it's a bargain.
