I will make something tomorrow, but let's be clear for a minute.
1. The M43 has a 2x Crop factor VS the Standard = FF (Full Frame). Meaning that your X5, X5R or X5S like the Panasonic GH4 or GH5, for example, has the same 2x Crop Factor. Meaning that your 15mm is, in fact, a 30mm one. On my GH4/5 my 8-16 is, in fact, a 16 to 32 and my 12-35 is, in fact, a 24-70mm. Got it?
2. While most M43 camera (Photo cameras) are normally all equal when it comes to shoot Photos with a 2x Crop factor, shooting videos is a different beast and higher the resolution is higher the chance you have to get a higher crop factor and this for technical reasons (Power, Heat...). The X5 is roughly the equivalent to a GH4. And while the GH4 had a 2x Crop factor on Photo and HD Video in 4K the crop factor was 2.3x. Meaning that your 15mm was, in fact, a 34.5mm.
3. I thought that the X5 had the same 2.3x crop factor as the GH4, but it seems that actually, it is a bit more than that, explaining my question... What is the official Crop factor on the X5 in HD and 4K.
Note : The GH5 comes now comes with a full readout of the sensor in 4K, meaning that the Crop factor is now 2x in 4K instead of 2.3x like on the GH4.
