75/1.8 is not for me (family/enthusiast photographer)

Hello Corkcampbell. First I have to say that I shoot portraits/portraits and portraits with the 75mm.  It's difficult for me to judge differences in sharpness between 45mm and 75mm Zuiko, because I've used my 45mm too little to make a correct comparision. I have the OM-D since a few weeks now (coming from E5), and the 75mm is my most used lens at the moment.   Despite that, my first impression is that they are pretty much comparable in sharpness. Maybe slightly better in the 75mm. That's only my first impression (nothing scientific about that). The handling/build quality (feeling it is enough) is much better on the 75mm. Beside that I find the background blur on the 75mm of much higher quality than the 45mm (I know, I know, that's a personal taste). That's what I really like about the 75mm. You can ofcourse always look for (sharpness)tests anywere on the internet. As I said before, it took some time to change some shooting habits using the 75mm for portraits (distance), so I forced myself to use this lens as much as possible. It was well worth it, because the results are simply magic and extremely sharp! With the E5 I always wanted the SHG 150mmF2 because of it's excellent IQ/sharpness (but the price was a bit too steep for me). I now feel, that I've got that quality in the 75mm. At the moment it already feels a bit awkward to use the 45mm. I never ( and I mean never), use video, so I cannot comment on that. Others certainly can.

Oh well, I just keep on talkingtalkingtalking. Sorry for that. I hope you'll make the right choice. Maybe you can borrow or rent any of these lenses from someone. At least try them out in a shop! Good luck !
