[0.565 lb] I've been using this lens for almost 3 weeks. It feels well built and hard. This is a completely manual lens, so you will have to figure out how to focus properly. Fortunately, Sony cameras have an option to enlarge the image both in the view finder and the screen, so it definitely help to make sure your image is sharp. The extra wide angle of this lens is stunning; perfect for small spaces, or if you want a quite impressive effect when taking close ups. I noticed very little distortion on my images, but definitely a bit of vignetting. In general, I'm very satisfied with this lens.

[7 x 5.5 x 1.7"] Put it onto one of my small fuji bodies. It has stayed there making me wonder what camera I will put my 23 onto. I had a 15mm voigtlander that I loved. Just set the aperture to 4.5 or 5.6, set the infinity distance to 4.5 or 5.6, control exposure with shutter speed and you are good to go: everything is in focus. This can capture interiors and outdoor scenes with a focus object like nothing else. Great for combined interior/ exterior through a window shots.

[0.565 lb] I bought it for some specific shots in a commercial and that lense do the job very well. Feels very good quality and super light.

[0.565 lb] I am not one to uncritically praise third-party lenses, and I own quite a few, but this one stands out in my collection. It's small, light, fun to shoot, and optically very, very good. It's not just good for the price, it's good, period. (If you have the budget, you can get marginally better optics from a top-tier German manufacturer, but dollar-for-dollar this one is an excellent value.) And its flaws are really minor; you will only see them by pixel peeping in just the right kind of images. It's also quite resistant to flare and ghosting, producing very nice landscapes and sunstars. Bottom line, you can make a lot of great images with this lens.

[7 x 5.5 x 1.7"] As a hobbyist and amateur photographer, I really loved this. I took it on a big 20-mile hike, and it's the best because of its light weight. Every ounce really makes a difference! It's my only lens that is light enough that it doesn't tip the body on my XT4 over. It's ultra wide frame makes it great for landscapes and astrophotography. I look forward to getting more creative with my framing too. No regrets here!

[7 x 5.5 x 1.7"] I got this at below market value and it is absolutely worth it. it makes Grand Central look even bigger than it already is!

[0.565 lb] So compact and build quality is so good! Does the job perfectly every time.

[0.565 lb] Purchased this lens in 2018 so I feel qualified to write a review. This lens is so fun. It's ridiculously small, and ridiculously sharp. I've used this lens extensively for personal work as well as professional work. It renders buildings beautifully dramatized due to its extreme field of view. There truly is no barrel distortion, even at such a wide angle. I am passionate about architecture and it's my go-to lens anytime I want great photos of a space. The one thing I wish different were the vignetting when shooting wide open. When stopped down the vignetting disappears. It's extremely sharp the entire aperture range. Build quality is pretty solid. I am not careful with my gear and it has taken quite a few bumps. The lens cap and hood are very high quality.

[0.565 lb] This lens is a gem for real estate shots, it gives me great results and zero distortion is wonderful.

[0.565 lb] As the headline says, I'm loving the super wide angles this lens gives me. It's a bit finicky to use on my Canon M6, but once I set the menu options properly I was off and running. In fact, with the amazing DOF at f/11 and f/16, I may just turn off focus peeking. The lens could be a bit sharper--I would give it 4.5 if I could, but am happy enough to round it up to 5 stars.
