So admittedly, this is not the n ☁ function of a tripod clamp, but it is, I find, a bad habit regularly present on Sigma lenses, which I also find to a lesser extent on the 150-600mm. However, I find the grip to be really inconvenient at all for freehand use, as it is too small and too stuck to the lens, so it is very difficult to hold the lens by hand via this grip (and yet I have small hands). Once the knob is tight, nothing moves, which is a very good point for the stability and safety of the object. Sigma 150mm f/2.8: Tripod Collar and Handle Using this collar also allows you to instantly switch from landscape mode to portrait mode, which is often done in macro photography, which is therefore very practical. The clamping wheel is quite large and therefore takes up a bit of space in a camera bag, but the tripod collar can be easily and quickly removed by fully unscrewing the dial and pulling on it to remove the safety catch, which is a excellent point to emphasize. The Tripod Collar and HandleĪ collar, located in front of the settings panel, provides support for the lens when mounted on a tripod, reducing pressure on the camera mount. Then, anyway, I’ve always liked flares and it happens to me regularly not to use a sun visor at all. In practice, I think that having it or not shouldn’t change much in terms of rendering. Unfortunately, I was not able to test the effectiveness of this second lens hood, as the person I bought this lens from lost it, but it should be noted that the large size of this double lens hood may possibly be a problem if you shoot fearful species very closely. Note that if you plan to use the Sigma 150mm f/2.8 on an APS-C, a second lens hood supplied with the lens must be added to maximize its effect on this type of sensor. The Sun VisorĪ classic plastic lens hood is also available and will limit stray lights and therefore avoid flares on the images. This is what we will see in an entire paragraph dedicated to stabilization and its use in the field in next paragraph. Is this technology effective and is it worth spending 300 dollars more than the non-stabilized version? In theory, Sigma advertises a gain of 4 stops by activating optical stabilization, which makes it possible to work freehand at relatively slow shutter speeds and to obtain crisp photographs.
