Απάντηση: Re: Olympus EM1X φωτογραφία
Ξετρυπώσα ένα ενδιαφέρον συγκριτικό που δείχνει την υπεροχή της X στα textures (λιγότερα artifacts) σχεδόν σε ολα τα ISO :

Texture loss
Texture reproduction results show MTF50 of 1561 LP/PH with 15.1 percent artifacts (ISO 200) at high contrast. Low-contrast areas are reproduced nearly as well: 1541 LP/PH with 22.8 percent artifacts at ISO 200.
Better than the OM-D E-M1 Mark II, which produced images with MTF50 of 1064 LP/PH at ISO 200 in high-contrast areas (12.3 percent artifacts), and 915 LP/PH MTF50 in low contrast with 9.9 percent artifacts.
Images made at ISO 400 using the M1X show an MTF50 of 1508 LP/PH with 15.8 percent artifacts in high-contrast parts of the scene, and in low-contrast areas, MTF50 of 1373 LP/PH with 26.7 percent artifacts
ISO 800: 1479 LP/PH with 21.0 percent artifacts in high contrast; 1465 LP/PH with 26.7 percent artifacts in low contrast.
At ISO 3200, MTF50 in high contrast areas is 1383 LP/PH with 29.9 percent artifacts, with 1342 LP/PH with 40.6 percent artifacts at low contrast.
From ISO 6400 and above, texture reproduction becomes poorer, with, for example 1161 LP/PH at ISO 6400 in high-contrast scenes (35.9 percent artifacts), and 1168 LP/PH in low contrast (57.7 percent artifacts).
In the OM-D E-M1 Mark II, texture reproduction at ISO 6400 shows MTF50 of 492 LP/PH (7.4 percent artifacts) in areas of high contrast, and 397 LP/PH with 0 percent artifacts in low contrast.
Παρόλα αυτά μαζί με την αύξηση της λεπτομέρειας και αυτοί είδαν μια μείωση στο DR και έξτρα θόρυβο σε μεγάλες εκτυπώσεις σε σχέση με την ΕΜ1.2, έχει διαγράμματα και αναλυτικές μετρήσεις ανά ISO, ότι πρέπει για τον Ηλία...:BDBDG54:
