Sigma30mm F1.4 Contemporary DC DN Lens for Micro 4/3 Black

Micro 4/3 (MFT) systems have quite a few affordable and very good lenses, both Panasonic and Olympus.However when looking for a large aperture (f1.4 or larger) lens that's sharp and with shallow DoF, things get a bit complicated.Our options, with autofocus, are:Panasonic Leica Summilux DG 25mm F1.4 for USD 519.99Olympus M.Zuiko Digital ED 25mm f1.2 PRO for USD 1,199.99or this lens, the Sigma 30mm f1.4 DC DN Contemporary for USD 339.00Granted the Olympus has superior optics, is weatherproof and more solidly built but its 3.5X the cost!However the Panasonic Leica cannot claim any of those and is still a good USD 180 more.The only weird thing about the Sigma(and this depends on your needs) is its 30mm (60mm =) focal length. This makes it harder as a walk round lens but is actually more adequate for portraits. In my case it suits me fine as I'd rather have a 17mm (35mm =) as walk around lens.If you have a MFT system you should give this lens a try.

I wasn’t sure if this contemporary lens was going to have the sharpness that I desired, but after shooting with it for just one day, I can tell you that this lens is far above any Panasonic or Olympus lens of a similar price.I wanted to purchase the art series lens, but since they don’t make that lens currently, I thought I would take a chance on this lens. I am not disappointed in the least. The color rendering of this lens is incredible. The fit in my Lumix GH6 body is absolutely Perfect. On top of that, this lenses weather sealed. I have already shot in inclement weather with this lens, and the results were stunning.10/10 for sharpness, 10/10 for color, 10/10 no chromatic aberration, 8/10 focus speed. Because I am using this lens on a contrast based auto focus system, I can’t speak to how accurate this lens could be on a PDAF system, but I will say that it is pretty good.If I ever upgrade to the G9II, or the GH7, I will follow this up with a report on how it performs with such a system, but as a micro 4/3 junkie, I can tell you that this is the best lens I own now.I own several LUMIX lenses, but this Sigma is the greatest lens that I could have added to my collection. I am already planning to purchase the other two in the same series. I am very happy.

No issues solid lens and unbelievable for the price.

A fast, crisp, sharp 30MM lens. Excellent for any application.' Solid, sturdy, easy to control features. One of the best 4/3rds lenses on the market. Highly recommend'...Some examples:

The 30mm F1.4 is working well so far. It is nice a sharp at f2.0 for sure. I think it is sharp at 1.4 but I did see some images not as sharp. But, it may have been just some. I shot a party where I had a studio setup and shot a couple hundred shots during the portrait shoot. They all came out nice and sharp. Love the boca I get. Nice having F1.4. I did notice the sigma lens can struggle to focus in low light.

I always go with sigma for Sony and Nikon. This time I try it on my Lumix GX85.Best lens for the price.

- Extremely shallow depth of field. Fantastic for portrait photography and cinematic shots.- Fast auto focus- Comes with lens cap + lens hood- Robust, solid feeling lens. Slightly larger than the Lumix 25mm (1.7).Works beautifully with my GH5. This lens is replacing my Lumix 1.7 (25mm) for video interviews.Attached are freeze-frames from my video (4k video from Panasonic GH5).

Well built and handy. Sharp and fast autofocus. I use gx85 so it's very handy and light to use
