Personally, I'd buy second hand, and if you end up not using it much you can sell it on without losing much.
Try your 12-32 at both 20mm and 25mm to see which focal length suits you best.

How does the olympus 25 compare with the panasonic 25?The only 20mm I can think of is the Panasonic 20mm f1.7.
If that's the one... it's compact and has good image quality but the focus is relatively slow when compared to other lenses. I replaced mine with the Olympus 25mm f1.8.
You could also think about the Olympus 17mm f1.8 as mentioned by AMcUK. It's an excellent metal bodied lens with a good manual focus option with end stops and markings. I think all MFT lenses should be built like it
Good luck choosing.
Hi was in st Jessops and they have a Panasonic 25 mm for £145 he also said I should have looked at Fuji xt 20
