All I can say is wow! For a wide angle zoom lens this thing is insanely Sharp and the autofocus is quite fast! Ever since I switched over to Sony full-frame cameras I have dreamt about having this wide angle, unfortunately Sony prices aren't too nice on your pockets so it took a while to pull the trigger! lol but they are quite amazing pieces of Technology. This would definitely be a 10 out of 10 recommend although it's very pricey it's a beautiful piece of equipment to have in your camera bag! It's absolutely perfect for Real Estate and gimbal work!

This thing can capture 80-90% of the tightest spots with real estate. Only down side is the F stop is 4 but with a tripod, it doesn’t really matter.

This small but solid built, pack a punch of clarity, the sharpness is incredible, the bokeh is also excellent. With a little bit of high on price but I think it worth your bucks. Fit perfectly on a full frame camera fast focus and quiet iso motor. With 12-24 focal length is just perfect as a prime len , easy light weight perfect for vlog , big frame , real estate shooting, or just outdoor.

I have several premium lenses of varying ranges but a good wide angle lens was conspicuously missing in my gear and after a thorough research I decided to go with this lens and I couldn't be happier. This is the most versatile wide angle lens so far as it allows you to shoot close to your subject and also allow you to shoot as wide as you want and crop to your preference later. I'm highly impressed with the image quality that comes out of this lens and I would say that is the best $1700 I have spent on a lens.

Love this FOV so much I ended up getting the GM version a few months later, the f4 is sharp and light, just be carefull with the front!
