The Phoblographer’s Big Buyer’s Guide To L Mount Alliance Lenses

If you’ve joined the L Mount Alliance and want a one-stop-shop for all of your lens needs, this guide is for you.

A few eyebrows were raised when Panasonic, Leica, and Sigma joined forces to create the L Mount Alliance. This would be Panasonic’s first foray into the Full-Frame market, Sigma could have a platform they could call their own, and Leica could potentially get their lenses into more hands. The platform got off to a slow start, but now things are rocking and rolling, and a good collection of lenses are now available. We have created the L Mount Alliance lens buyer’s guide for those who have joined the L mount ranks. Here you’ll find all of our current L mount lens reviews and any future lens reviews for the platform too.

We’ve spent a lot of time testing these L Mount Alliance lenses in all sorts of conditions. Today, we’re sharing our findings for every single lens we’ve reviewed so far in an extensive guide that isn’t sponsored by any member of the L Mount Alliance. We simply wanted to put together an easy to find and simple to read guide for our readers. With that said, we have full editorial authority over what’s said in this guide. So if you’re interested in investing in the L Mount Alliance platform either through Leica, Panasonic, or Sigma, our guide will help you make better purchasing decisions.

Sigma 20mm f1.4 DG HSM Art

In our review, we said:

“The Sigma 20mm f1.4 DG HSM Art lens is sharp, contrasty, saturated, and overall delivers incredible image quality that you really can’t sit there and complain about. It’s a beautiful lens that will find its home amongst architecture photographers, street photographers, and landscape photographers. As I’m writing this review, I keep thinking about how sad I am to send it back to Sigma since the review is over.”

Sigma 30mm f1.4 DC DN Contemporary

In our review, we said:

“The Sigma 30mm f1.4 DC DN lens is quite good overall. It feels nice in hand, focuses quickly and accurately most of the time, and doesn’t give you the more typically well known Sigma color rendition. Instead, they seem to have toned it down a bit here with this lens.”

Sigma 35mm f1.2 Art DG DN

In our review, we said:

“In backlit situations with ample light outdoors, the Sigma 35mm f1.2 Art DG DN nails the focusing well. Here is where you’re not only able to appreciate the colors that the lens delivers but also the sharpness.”

Sigma 35mm f1.4 DG HSM

In our review, we said:

“Overall, we can’t really say anything very terrible about the Sigma 35mm f1.4 DG. Even though it doesn’t have weather sealing, there are options out there that can do this for you. Otherwise, it has a wonderful build quality, eye-popping image quality, and is a relative speed demon when it comes to focusing.”

Sigma 45mm f2.8 DG DN Contemporary

In our review, we said:

“Overall, the Sigma 45mm f2.8 DG DN Contemporary exhibits very good image quality. If you didn’t know any better, you’d say that this is easily the image quality that an Art or Sports lens in Sigma’s lineup would have.”

Leica SL 50mm f1.4 Summilux

In our review, we said:

“The image quality from the Leica SL 50mm f1.4 Summilux is arguably the best thing about the lens. Despite its big and heavy build mixed with slow focusing, it’s got incredibly image quality. The bokeh is gorgeous. Further, we couldn’t find a single problem with fringing or distortion.”

Sigma 50mm f1.4 DG HSM Art

In our review, we said:

“When it comes to image quality of the Sigma 50mm f1.4 Art lens, it truly is deserving of its Art moniker. This lens delivers some of the most beautiful image quality that we’ve seen and surely puts lots of the first party offerings to shame.”

Panasonic 50mm f1.4 Lumix S Pro

In our review, we said:

“The Panasonic 50mm f1.4 Lumix S Pro is a truly exceptional lens. It really delivers where it counts with image quality. This lens is not only very sharp but also delivers beautiful bokeh. Portrait photographers will appreciate the colors, as will wedding photographers and photojournalists. Those who travel will like the build quality.”

Sigma 56mm f1.4 DC DN Contemporary

In our review, we said:

 “In-focus areas are tack sharp while out of focus areas pack plenty of bokeh. Images produced by the Sigma 56mm f1.4 are consistently sharp in the center of the frame throughout the available aperture range (f1.4 to f16), with no significant loss in sharpness detected when moving towards the perimeter of the frame.”

Sigma 85mm f1.4 DG DN Art

In our review, we said:

“The Sigma 85mm f1.4 DG DN Art offers tremendous value. It retains the excellent image quality of its predecessor while addressing many of its shortcomings: It’s smaller, lighter, and features markedly improved autofocus performance.”

Sigma 14-24mm f2.8 DG DN Art

L Mount Alliance

In our review, we said:

“The Sigma 14-24mm f2.8 DG DN Art creates vivid images. We found this across both Panasonic and Leica’s cameras. The market Sigma is targeting with this lens cares about that. The saturated colors will look just as good in the rain and they will when shooting a landscape.”

Panasonic 16-35mm f4 PRO

L Mount Alliance

In our review, we said:

“In regard to the images this lens creates, it’s positively stellar. There’s less distortion than what I’ve seen with Sigma’s offering, and I find it challenging to take a bad photo with this lens. Landscape and cityscape photographers will thoroughly enjoy it. What they’ll appreciate the most is the sharpness mixed with the convenient size.”
