Small, sharp, fast, relatively light and comparably inexpensive. All things I love in a lens. ZY Optics has produced yet another ultra fast option for micro 4/3 shooters, but a first option available in a dedicated mount, faster than f/1.4, new for under $400.
The question now stands, how does this fit in with all the other standard/normal lens offerings within the micro 4/3 landscape? Well, more easily than you might think. While not perfect, it definitely has enough going for it to justify a look. C’mon in for my thoughts and some tests against the Pana-Leica 25mm f/1.4 Summilux…
Happy new year! I’ve been having a wonderful holiday season, largely thanks to Adorama for lending me this beaut of a lens. The Sigma Art 20mm f/1.4 is the widest, f/1.4 full frame lens, and is the newest addition to the much vaunted line of f/1.4 Sigma Art Primes available in Canon EF, Nikon F, Sony FE, Leica L and Sigma mounts. In this article, we’ll explore a bit of the more measurable aspects as well as the more touchy, feely parts of interacting with this lens. I shot this lens on both the Canon EOS 5D mkII and the Sony a7II via the EF>FE Metabones MkIV smart adapter, and it performed equally as solid on both cameras. Is this a viable option for full frame system shooters for fast, ultra wide applications? Well, seeing as there has never been a full frame compatible lens this wide, this fast, it’s forging new ground for many shooters, and that is pretty rare in this day and age. C’mon in to see some example images and read my rambling thoughts…
This little gem is on sale for $70 off right now. I’m not normally a sale pumper unless it is for stuff I use, I like and I would recommend. If you’ve been on the fence, or waiting for this lens to drop a little, here’s a great opportunity to save a good amount of money on a great little lens.

Or, if you’d also like to read the head to head (to head) between the Leica 15, and the two Lumix Pancakes (14mm and 20mm) I did a comparison article HERE.
It is a great mate to any of the micro 4/3 cameras, especially the GM bodies, and is compact and lightweight enough to go largely unnoticed in the bag. I’ve been shooting the 15mm on the new GX8 with its 20mp sensor providing great results for me.
Most of us have heard of the Sunny 16 rule by where the rule of thumb for “proper” exposure on a sunny day would be setting your aperture to f/16 and your shutter speed to 1 / x, where X = your ISO setting. Basically, at f/16 and shooting at ISO 100, we would set our shutter speed to 1/100 and you’d be set (1/200 at ISO 200, etc). Of course there are other variables to take into consideration depending on your desired outcome or subject, but it gets you close enough. Well, after some trial and error (emphasis on the latter) I came to realize that when shooting the moon, I was having a very hard time properly exposing it. Wanting to eliminate as much noise as possible, I was shooting at lower ISOs and after some more trial I found that I was coming in at about f/5.6- f/8 when spot metering and compensating for the extra brightness (I figured I should account for about 2 full stops over midtone) with the same one over rule as the Sunny 16… This got me wondering if there was in fact a night shooters rule of thumb, and there in fact is…
