Both lenses are very good quality but anyone serious about portrait work would not choose between those two lenses between a small size difference but would base their choice on the BIG difference in focal length

Unless one shoots mostly head and shoulders portrait there is no doubt that the FOV of the Nocticron is MUCH BETTER suited to portrait work


Not my experience with the focal length of 43mm you need a lot space for more than a headshot at 1 meter the frame width is only 41 cm

This is ALL untrue . First of all the Nocticron is actually wider than the 42,5mm of the Lumix lens . there has been a few tests on you tube to show that and since I have all this 40mm something lenses I conducted a test myself and was able to determine that the Nocticron is closer to a 41mm.

It may not sound like much but in real life at the short distances you mentioned it does make a BIG difference

so to get a person in full and some headroom you need 4.5 meters in my house I have only one room that is that long

unless you photograph people over 7 feet tall this is exaggerated . normally you can get someone full length with a shorter distance than the one you mentioned

I don't have a dog in this fight (sadly, perhaps, I recently sold my Noct), but it's a little strange to see folks arguing over math. As Interceptor notes, at 41mm on m43, the vertical FOV is less than 1m.

If you're taking full body portraits with the Noct, you'd need a good 4.5+ meters, depending on the subject's height of course (5 meters gives a vertical FOV of just over 2m).
