[0.21 lb] I haven't really gotten a chance to use it, other then a few test shots around the house. Taking it camping this weekend to get some milky way and landscape shots so I'll know more after that. Rating it 5 stars for now because of the timely shipping and the feel of the lens, the focus is smooth, and the lens feels well built.

[f/1.2] Excellent value: 10-12 Mp Optical resolution and nice price. Fits our needs perfectly.

[f/1.2] It was very difficult to find a 1/1.8 sensor format lens with a focal length of about 4 mm. This lens is perfect for my Point grey camera with that sensor format.

[0.21 lb] This is quite a nice lens. Even when wide open the image is really sharp in the centre. The colours are neutral. The build quality is excellent. The focusing feels better then my Sigma 30mm art.

[CS-mount] I wanted a wide angle lens to finish my lens line on the wide end. I wanted something pretty fast with good optics. This lens fit the bill.


I was a little hesitant to get a strictly manual lens but I have had no issues using the manual features. Plus, my Panasonic G85 does some auto functions even with the full manual lens.


The lens was longer and heavier than I expected. It's about the same length as my 100-300mm Lumix lens and a few ounces heavier. This has not been an issue since the f/2.8 handles low light pretty well even without a tripod. I really expected to see a significant fisheye distortion but was very pleasantly surprised at how little there is. This lens is already seeing use.

[f/1.2] great for closeups, portrait epic style and landscape... but most important to me... to capture the milky way at night...

[1/2.7"] I bought this for my K-50 because it was designed specifically for APS-C format cameras. Absolutely delighted with how it worked during our recent trip to Grand Teton and Yellowstone National Parks. The depth of field is amazing - when shooting in bright light I set the f-stop to 4 or 5.6 in AV mode and then set the lens using the depth of field markings. The K-50 happily chirped every time, telling me it was in focus. During the evenings for night sky shooting all I had to do was open it wide to f/2.8 and set the focus marking to infinity - I tested that during the day time as well. Perfect pinpoint stars near the center and just a trace of astigmatism at the corners - very good performance. Looking forward to using this beauty during future travels that take us into grand buildings, where the ultra-wide rectilinear performance will really be handy. Should have bought one three years ago.

[2.4 oz / 67 g] Bought 2 of these, super satisfied, very sharp and versatile zoom range.

[f/1.2] I service 5 airports and we purchased this lens to look 2,000 feet down one of our runways. I am not even using all of the zoom. It provides a good picture. I coupled it with the EverFocus EVEQ700 box camera.

[f/1.2] Exactly the proper lens for our camera
