Re: G5x Digital teleconverter vs crop

Thank you Olf for taking the time to post a response.

Unfortunately I do not understand the details of your first paragraph. I am a retired electrical engineer and this optical stuff is a bit "over my head" 

I think I get your second paragraph, as I also did some "trial and error" tests and noticed that in digital tele converter setting for example at 2x setting, the entire lens range is doubled, at the 24 mm wide angle I get 48 mm, and at the max zoom I get 200. If I understand your comment correctly digital zoom provides a better magnification at the wide angle setting (24mm), same as if I would use the optical zoom only.

The third paragraph goes over my head again, sorry. But if I get this right, I should use optical zoom only and crop in post processing (crop) with Photoshop Elements. I am not shooting RAW, too much work imho. I read that using digital zoom all the way (17 x or ~ 400mm)  has a big IQ impact. So, I would like to limit my use to either digital tele converter (2x setting) or digital zoom to a max of 8.4x, (yellow bar)  which would be the optical zoom times two. What I don't understand is if the IQ at the 2x tele converter setting is exactly the same as the "2x" going the digital zoom route to 84.x or do those two software tools use a different algorithm, resulting in one of the setting having a better IQ than the other? If so, which provides better IQ

If you have the time, and the patience with me, please elaborate on the third paragraph please.

Thanks,

Wolfgang
