ISO performance X-Trans 3 vs X-Trans 4

Hi,

Until a while ago I only photographed with the X-T2, X-H1 and X100F, all X-Trans 3 sensors. When the X100V was released, I immediately updated to this camera, if only because of the new lens. I really liked the images. I am now back to an X-Pro3 (really like the X-Pro 3! Previously had X-Pro1) as I shoot a lot with prime lenses. I updated my X-T2 to the X-T3 during the winter sale. It strikes me now that the X-T3 and X-Pro3 (with X-Trans 4) handle high ISO values less well than the previous sensor. More who suffer from this? It's not a big deal, but it does strike me.

Re: ISO performance X-Trans 3 vs X-Trans 4

My X100V seems maybe a tad better than the X-T3 I had briefly but, at very high ISOs, both fall a bit short of what I can get out of the X-T2/X-T20. With some modifications to my post processing they are pretty close, though.

I think the general concensus is that the newer sensor is a bit noisier, but retains a touch more detail. Not that much in it, though!

In my experience the newer sensor does not retain more detail, and actually comes up quite a bit short if you clean up the noise enough to match the old sensor. YMMV.

I have the XT4 after previously owning an XT1 and there is slightly, emphasis on slightly, more noise at comparable high ISO, but I'm not suffering from this in the least.

The difference is basically a nit.  The X-Trans 4 is base ISO 160 while the X-Trans 3 is 200.  At base ISO my Pro3 was a little better ( but the operative term is little) than my Pro2.

At high ISO it is pretty much a wash.  There is some minor difference in the rendering but again it is a wash. My preference but not by much is the Pro3 over the Pro2 but most that preference combines from the lower base ISO.

You are correct. Very slight edge in high ISO with my X-T2 as opposed to my X-T3s.

Just requires a little more care in the PP of images.
