Is the Lumix 42.5mm f/1.7 the new affordable reference for MFT portrait photographers? Let’s find out! I've used this lens extensively for professional assignments and private commissions, and it has come through every time. Obviously it's designed as a portrait lens, but I also find it great for street photography and reportage (which are typically the realm of 35mm equivalents). Falloff of illumination towards the corners is very well controlled, especially so for a fast aperture lens. At f/1.8 the corners are only 0.76 stops darker than the image centre and visually uniform illumination is achieved at f/2.8. m4/3 ที่ทำการละลายหลังได้ยาก แต่เลนส์ตัวนี้ก็สามารถละลายหลังได้ในระดับที่ดี เหมาะกับการใช้งานด้าน Portrait มากๆ The final point in its favour is the weather-sealing, which can come in handy if you frequently work outdoors and already use a professional weatherproof body such as the OM-D E-M1 II. The manual focus ring is also more pleasant to use.

In the two tables below you’ll see how the Lumix 42.5mm f1.7 compares against the Olympus 45mm f1.8, first in the middle of the frame, then in the corner. Note due to its slightly longer focal length, the Olympus is delivering a slightly tighter field of view and therefore resolving slightly finer details. The thing to look for in the comparisons below are the overall sharpness and contrast. First and foremost is the optical quality, particularly at the fastest apertures. Not only is the PRO much sharper when both are set to f/1.8 but it also outperforms the cheaper lens at f/1.2 – not to mention that you can achieve better subject separation.Chromatic aberration is the lens' inability to focus on the sensor or film all colours of visible light at the same point. Severe chromatic aberration gives a noticeable fringing or a halo effect around sharp edges within the picture. It can be cured in software.

No matter if on the other side of the world or in front of my door here – the degree of sharpness the Leica lens delivers is remarkable, especially wide open, turning it into a monster even in low light conditions. It's an absolutely fantastic portrait lens that's also adept at day-to-day photography if you know how to use it. So while this is mainly one for the headshot hunters, it's more versatile than it seems –and if you want to try your hand at portraiture, it's such low price and great value that you can't really go wrong.

For my part, I’m glad to own both lenses and I find great joy in each one. Thanks for reading this and see you on the streets! With the lens wide open, you can see some light fall-off in the corners, but it is not very severe, and goes away almost completely upon stopping down to f/2.8. The 42.5mm f1.7 defends itself quite well against its big sister, the Nocticron 42.5mm f/1.2, although the latter has more sharpness. Of course, the 45mm f/1.8 isn’t without its merits. Because it is so small and light, it is much easier to transport and can suit any Micro Four Thirds body in the range. It is also four times cheaper than the PRO lens, so unless you regularly shoot portraits and require the best quality Olympus has to offer, it (or its sibling within the Panasonic Lumix range) may prove a more tempting proposition.

In the past I never used lenses pouches with my larger lenses, but with these smaller rangefinder like lenses, I put all my lenses into pouches before they go into my bag. This is one disappointment I have with Olympus which Panasonic is one step ahead with even their Leica lenses. Hood and Pouch should be included in the price of this.
