Wide open we are dealing with 3.6 EV in the most extreme corner. The results in the shifted area are of course very different.
Compared to normal 15mm lenses this is good, but about 0.3 EV worse than the Canon TS-E 17mm 4.0L. Wide open there is still vignetting of roughly 2.0 EV, stopped down to f/5.6 this improves only 1.6 EV and stopped down to f/11 it is still around 1.2 EV. When using the the lens centered (unshifted) you are only using the central part of the lens, so vignetting should be less of an issue. You will read more on those here when I got to check them out, they were unfortunately not available when I received this review sample.Īs this lens is a very complex ultra wide angle design I recommend using the Sigma MC-11 adapter (affiliate link) to get the best performance out of it. There is no hood available for this lens, but there will be a lens specific filter holder (rumors say 100 mm) and also a rather sophisticated Rear-Shift adapter. The build quality is pretty much in line with other recent Laowa lenses: the 15mm 4.5 Shift seems to be mostly made from metal, but to me it looks like only the markings on the focus ring and the rotator are engraved and filled with paint whereas the ones on aperture ring as well as the distance scale look like they are just printed. Laowa 15mm 4.5 Shift fully shifted and Canon TS-E 17mm 4.0L fully shifted and tilted To me personally this is all but a big deal, I never felt the tilt being very useful when it comes to ultra wide angle lenses, but if you need it you already know that and can choose your lens accordingly. Unlike on Canon’s TS-E and Nikon’s PC-E lenses there is no tilt, the Laowa can only shift. When you fully shift your lens in every direction and take a picture at every 30° rotation this is the panorama you will get, I added the Canon TS-E 17mm 4.0L and the Laowa 9mm 5.6 for comparison ( I must have hit the tripod when changing for the 17mm lens, hence the slightly horizontally tilted panorama here): The lens not featuring any electronics is an advantage here but this of course also means no EXIF data is transmitted to the camera. The ring has a high resistance and I have the feeling the mechanism is also stiffer than that of the Canon TS-E lenses, I never felt the need to use the shift lock knob.Ĭlose to the bayonet is a little lever, if you push it the whole lens can be rotated 360° (with 15° click stops) therefore allowing you to shift in every direction. Those critics may like the Laowa approach: here you have a big ring (pretty much same size as the focus ring) to adjust the shift value and on one side of the lens you have a scale that tells you the amount shifted from -11 mm to +11 mm. These have often been criticized for being rather delicate and hard to operate when wearing gloves. The Nikon and Canon lenses feature a locking knob on one side and an adjustment knob on the opposite side. Next is the shift ring and here we have a very different design compared to the Canon TS-E and Nikon PC-E lenses. Considering the complexity of this lens I wonder why the click stops are not equidistant though. The narrow aperture ring is situated right behind the focus ring and has full-stop click stops – which is always my preference – and travels ~60° from f/4.5 to f/22. The focus ring travels ~100° from the minimum focus distance (0.20m) to infinity, so the focus throw is a bit longer than that off the Canon TS-E 17mm 4.0L. The focus ring has a really nice resistance which has been the case for all the latest Laowa lenses. Regarding Shift and what it can be used for best have a look at my article Working with Tilt/Shift lenses.

Maximum Magnification: 1:5.5 (measured).Number of Aperture Blades: 5 (straight).Length: 103 mm (+adapter, without caps).Field of view: 110° (diagonally, unshifted).The new 15mm 4.5 Shift comes in Canon EF, Nikon F and later in Sony E, Nikon Z and Canon RF mount, I am reviewing a Canon EF sample here which has the following specifications: The Laowa 15mm 4.5 Shift is not to be mistaken with the Laowa 15mm 4.0 macro as it is a completely new and very different lens.
