Canon EF 50mm f1.8 is the king of C/P value. After several generations, the image quality, AF speed, and sunstar are already very good. The weakness of this lens is the flare and corner resolution.

Canon EF 16-35mm f2.8 L II, is the second generation wide angle zoom lens of the remarkable canon 16-35mm family. As a classic DSLR lens, this lens will deliver sharpest image at small aperture like f11 or f13, also the bokeh is nice when you try to shoot some portrait at 35mm. The edge image quality is the obvious weakness of this lens, however, there are very little other disadvantages we can found. This lens has decent sunstar start from aperture f4.0 due the asymmetry nature, which is the main difference between f2.8 L II and the f2.8 L III. Other Canon wide angle lens like EF 16-35mm f4 IS or RF 15-35mm f2.8 also don’t have this asymmetry sunstar nature, which make this f2.8 L II lens the most unique and most recognizable landscape lens. In conclusion, the EF 16-35mm f2.8 L II is undoubtedly the KING for the sunstar and landscape photography.
Canon EF 35mm f2 IS USM is a nice and light weight prime lens. It has pretty good autofocus and image stabilization performance. The main weakness of this lens is that the same price competitor, Sigma 35mm f1.4 ART, is so strong. Also the Canon EF 35mm f1.4 L II is almost a perfect lens for this focal length, so the 35mm f2 IS is rarely be mentioned. The sunstar is not very good but still fine, and the lens flare is well suppressed.
The Panasonic Leica 12-60mm lens is a versatile standard focal length zoom lens designed for the Micro Four Thirds (M43) system. It stands out with its impeccable build quality and impressive optical performance, making it a reliable choice for a wide range of shooting scenarios. One of the standout features of this lens is its ability to handle sunlight, producing beautiful sun flares and stunning sunstars that add a creative flair to your photos. This characteristic, combined with its compact and durable design, makes it an ideal lens for travel photography, where capturing dynamic and diverse environments is key.
However, like many lenses designed for the M43 system, the Panasonic Leica 12-60mm does have some limitations, particularly in low-light conditions. Whether you’re shooting night scenes or indoor environments with limited lighting, the lens can struggle to perform at its best. This is not so much a flaw of the lens itself but rather a limitation inherent to the M43 sensor format, which typically has smaller sensors compared to APS-C or full-frame systems, resulting in reduced light-gathering capability.
For the purposes of our tests, we paired the Panasonic Leica 12-60mm with the Panasonic GX85 (also known in different markets as the GX7 Mark II or GX80). This combination allowed us to fully explore the lens’s capabilities and assess its performance across a variety of conditions, including the aforementioned challenges in low light.

Panasonic Leica 15mm is a classic M43 lens. The image quality, AF speed, and build quality are great. However, the sunstar profile is a weakness of this lens. The sunstar will only be converged at F16 for strong light point.
