+242 ptsâThatâs great. With the price drop of the A7 IV the A7 III on the used market will also go down, which means I can finally afford the A7 II.â

Best Praise
+53 ptsâNot Topaz, just Lightroom. I've never tried Topaz, maybe I should. I think that the noise pattern of the A9iii is particularly easy to fix. I don't get such great results from my A7Rv.â
