Testbericht
The Leica APO-Summicron-SL 90mm F2 ASPH is a high-performance prime lens, designed for the L-Mount, that sets itself apart with its remarkable optical quality and build. This lens is ideal for portrait and general photography, where sharpness and impressive bokeh are essential.
Design and Build Quality
One of the first aspects you'll notice about the APO-Summicron-SL 90mm is its stellar build quality. Designed with durability in mind, this lens boasts a weather-sealed construction, ensuring it can withstand the rigors of various shooting conditions. The metal body feels robust and solid, lending to an overall premium experience that matches the Leica brand's legacy.
Optical Performance
The optical performance of the APO-Summicron-SL 90mm is nothing short of exceptional. It incorporates advanced technologies, including aspherical elements and low-dispersion glass, which significantly reduce chromatic aberrations and distortions. The result is sharp images across the frame, even at wide open apertures. The f/2 maximum aperture not only allows for beautiful subject isolation but also performs admirably in low-light situations. Moreover, the out-of-focus rendering is creamy and smooth, making it a joy to use for portraiture.
Autofocus and Usability
This lens features a fast and precise autofocus system, which is a boon for both professional photographers and enthusiasts. The autofocus is virtually silent, making it suitable for discreet shooting environments. Additionally, the lens accommodates manual focus, with a well-damped focus ring that provides a tactile experience when fine-tuning focus, ensuring that you can achieve that perfect shot with ease.
Crop Factor Consideration
As a 90mm lens on the L-Mount, it's important to consider the effective focal length when using it on different sensor sizes. On full-frame models, it behaves as a standard telephoto lens, which is advantageous for portrait photographers looking to achieve that coveted perspective. However, if you plan to use it on an APS-C body, you'll need to account for the crop factor, which may change your intended framing.
