There is a whole lot of glass in this lens and therefore it feels very dense. It is possible to operate them when wearing winter gloves, but it is still not super easy (on the latest T/S lenses Canon further increased the size of the knobs). The tilt part can be rotated by 90° and has one 45° click stop.Ĭompared to Canon’s older T/S lenses the size of the knobs has been increased. When you fully shift your lens in every direction and take a picture at all the settings with a click stop this is the panorama you will get ( for portrait orientation I had to move the camera and then I did not go through all settings again, hence the greyed out parts and not perfect overlap):įor tilt you have the same two knobs but an additional locking lever if you really want to make sure not to accidentally add some tilt to your images. The shift part can be rotated by 180° and has 30° click stops. These can be adjusted if you think they are too loose or too tight. This is not a very long throw but taking into account the short focal length I never ran into any problems focusing precisely.įor shift you have a locking knob on one side and an adjustment knob on the opposite side. The focus ring travels ~80° from the minimum focus distance (0.25m) to infinity. the Voigtlander E-mount lenses (this may be due to my sample being a used one). The focus ring runs smooth and without slack but the resistance is a little lower compared to e.g. Regarding Tilt and Shift and what those can be used for best have a look at my article Working with Tilt/Shift lenses.Īs said before this lens has two points of rotation so you can set any combination of tilt and shift, as you can also see in the following pictures: from /, they can be found starting at $1500/1400€ (affiliate links) I rather recommend getting a good used one, e.g. New this lens is still pretty expensive, you can buy it from / or B&H for $2150/2000€. ![]() You may also have a look at the official page. Maximum Magnification: 1:7.1 (measured).Number of Aperture Blades: 8 (slightly rounded).Length: 107 mm (+adapter, without caps).Field of view: 104° (diagonally, unshifted).Together with the Canon TS-E 24mm 3.5L II it was the first full frame T/S lens that can do any combination of Tilt and Shift without any modifications. An average CA width of around 1px at the image borders is very good in absolute terms and even more so for an ultra-wide lens.This lens was introduced in 2009 and is still the widest T/S lens available. If you want to know more about the MTF50 figures you may check out the corresponding Imatest ExplanationsĬanon claims to have optimized to the lens with respect to lateral CAs and our findings to support this statement. The chart shows line widths per picture height (LW/PH) which can be taken as a measure for sharpness. Please note that the MTF results are not directly comparable across the different systems!īelow is a simplified summary of the formal findings. ![]() At f/16 the quality is still good to very good across the image frame. Diffraction effects decrease the quality a little at f/11. Stopping down to f/5.6 and f/8 boosts the borders well into very good territories and the extreme corners follow closely. aperture whereas the borders/corners are on a good level. The center resolution is already excellent at max. The resolution characteristic of the Canon lens is impressive. Technically the vignetting is naturally still fairly pronounced at f/4 ~1.3EV) but this is very acceptable for an ultra-wide lens - the Canon EF 16-35mm f/2.8 is worse f/4 for instance. The Canon lens has an immense image circle so it's no surprise that its vignetting figures are about as good as it gets today. ![]() The chart above has a real-world size of about 120x80cm. This is highly impressive for a lens in this class. It shows only slight barrel barrel distortion of just over 1.1% albeit based on a somewhat wavy subfrequency. Ultra-wide lenses tend to be a bit "laissez-faire" when it comes to distortion but the Canon TS-E 17mm f/4 L plays in a different league here. Let's begin with our technical analysis based on lens in its conventional setup with both the tilt as well as the shift aspect in their respective neutral settings.
