Sony - FE 12-24mm F4 G Wide-Angle Zoom Lens (SEL1224G),Black

Personally, I'd avoid buying the G Master version in favor of this one. Save some money. This one has the same FOV, and if you want to take photos in a darker room, set up a tripod and use a longer exposure. If you're looking for something to shoot Astro, there are better lenses than both this and the G Master version of this. All in all, this lens has everything I need. Highly recommend for wide field landscape or real estate.

La calidad es muy buena, pero lo que no me gusto y hasta pense regresarlo si no fuera por que lo necesitaba es que a los pocos días bajo el precio bastante y con el mismo provedor.

I create photography and video tours of Realtors, Architects, and Builders. A big part of what I do is shooting video of me "walking through" a house. Showing how rooms connect together and such. This lens is perfect for that.Speed is essential for what I do. The light levels in various rooms of a house can be VERY different and as I walk from room-to-room I can't be manually dialing in ISO/Aperture settings. I need the camera to do this for me on-the-fly.This lens enables me to do that.I typically film at 16 mm but will sometimes go to 14mm for very small and cramped spaces. This lens allows for that. In order to be able to work quickly I shoot in S-Priority and Auto ISO. Here's how that helps.When shooting S-Priority and Auto ISO together the camera will work "both ends" of the histogram. That is, when I walk into a darker space like a master bedroom with darker, more intimate paint on the walls, the camera will open aperture all the way to F4 and then start boosting ISO to account for the lower light levels. When I walk out of that room into a brightly lit great room the camera will bottom out ISO and then start crushing down the aperture to protect highlights. All on the fly.I've seen the camera go all the way to f16 because the light was too bright where the camera was pointed but then as I panned to the right and moved to a different place it would go to f8 and then ultimately back to f4 again as I stepped into the less brightly lit space of the kitchen.A manual lens would not be able to do this. You need a fly-by-wire lens like this one. And this is the only fly-by-wire lens that will allow me to go wide all the way to to 14mm. I used my 16-35 f4 for a year or so before getting this lens. It worked well but I was always frustrated in those situations where I needed to go to 14mm and couldn't.Ultimately, this lens is ideal for creating walk-through real estate videos or for filming the walk-through portions of more complex films like "behind the design" style architecture documentaries.

Downsides: relatively big, heavy, and expensive; you get what you pay for.

If you need a wide angle lens, I couldn't recommend this option more! After purchasing the 16-35mm GM, it just doesn't compare in terms of versatility, and the lens quality of the G produces arguably sharper images overall. Plus, it pairs very well with the 17-28mm option on the market in case you need something with a lower f-stop for astrophotography or low light shooting. Don't even think about the 16-35 GM. Get this one instead.
