Sigma 24mm f/2 DG DN Contemporary (I-Series)

Jonathan-Mac · Jul 18, 2023

I just got this and haven't had much chance to use it and all of that has been close subjects rather than the landscapes or cityscapes I imagine it's also ideal for. I've done some portraits of my daughters which came out nice - f/2 is fast enough for a de-focused background and as long as you centre the subject a portrait can be nice. The f/3.5 version didn't allow me to do this.

It's very, very sharp in the centre wide open. The picture of the flower is a bit glowy and I'm not sure if it's a missed focus or a quality of focusing so close as the tomato shows no glow even at 100% and it's focused just as close.

Thanks for sharing these.

The flower is back-focused.

I hadn't been planning on it but decided at the last minute to take the 24mm f/2 on my recent holiday to Venice, Montenegro and a few Greek islands. It didn't get much use off the cruise ship (except in Venice before we boarded) as I was using the 24-70mm f/2.8 Art to avoid lens changes, but I have been very, very impressed with it's performance. The speed is nice to have and photos have a vibrancy that I think the 24-70/2.8 lacks. I found it particularly useful for handheld night shots where I think I used it wide open down to 1/15s with no problems.

I used this lens for my first foray into astrophotography this past weekend and it looks to me like it did a god job. The first shot is a long composite exposure, which is a feature I hadn't used before but it's perfect for this kind of shot. The second is a much shorter exposure, just thirty seconds, to avoid trails (though you can see if zooming in to 100% that all the points are elongated).

The most difficult part was focusing properly on the stars. That and cursing when a plane flew over and ruined the shot.
