Sony FE 50mm F1.4 GM or Sigma 50mm F1.4 DG DN Art or Other

Some reviews show a lot of CA with the Sigma, that would make me a bit nervous.

I don't know how the Sony compares, though.

I currently own the 50 mm 1.2 GM and it is not worth selling this lens to get the F1.4 version.

However, if the Sony 1.4 GM existed before the F1.2 version I probably would have went with the F 1.4 GM.

I have also used and owned and sold the Batis 40 mm which was a nice lens. As my needs change I will sell and buy gear. The nice thing about 40 mm I liked was the middle ground of 35 mm and 50 mm. It was unique.

I suggest if you own a zoom lens that covers the 50 mm range already set the lens at 50 mm and shoot here, dont move FL and decide if that is how you want to see the world.

Same trial for 35mm and 40 mm. Use the EXIF to confirm zoom lens position. That is what led me to the 40 mm to begin with. At that time I really did not care for the Sony /Zeiss version of the 35mm or 50 mm that is how that happened.

I would not buy the Sony GM (either one) or the Sigma at current prices. $850, $1300 or $2000 (f1.2) for a 50mm lens is loony. What do you want to use it for? Blown out background bokeh portraits? An 85 f1.8 will give better background separation at better working distances. Landscape? You'll be shooting at f/8 so why pay for f/1.4?

Don't get me wrong. I really like the 50mm focal length. I use it mostly for street, product and macro work. In all those situations I'm at f/2.8 to f/8 so f/2.8 lenses work great. The "old" Sony FE 50mm f2.8 Macro and Zeiss Loxia 50mm f2 are both fantastic. Yes, the autofocus on the Sony macro works about as fast as the "auto" focus on the Loxia. But for zone focused street shots and manually focused macro they work great.

Low light photography?

Full body portraits (of children) with some separation?

Plus the other stuff with smaller apertures.

50mm is very handy In constraint spaces, I use mine for portrait whenever I’m in such situations, albeit MF lens (No issues with MF for relatively slow moving portrait sessions) and for whole body shots.

If I really want blown out background I take my 135mm the 85 has nowhere near the separation of that… lol

50mm is very useful indoors shooting subjects - 85mm is mostly too long, 35mm not enough separation. And some like it for more 'natural' face features/rendering/compression.

Better, but still far too expensive for me.

But as we’ve established, I’m more interested in an f/1.8 or f/2 lens.

Although my 35 mm f/1.4 G Master is incredibly small for its specs and performance, it’s still annoyingly heavy to carry around for four hours. So I’m not interested in a 50 of about the same weight.
