is a fantastic wide aperture lens which is commercially available, affordable and a great value. Personally I tend to get bored if I am walking around with a 50mm lens but with that lens, the challenge of manual focus, the ability to take photos with hardly any light, and the ability to take dreamy photos like people have never seen I have so much fun. They make it for all the major camera brands.
Overall I am impressed with Chinese lens manufacturers who make other lenses like

which again are a great value and let me take pictures you haven't seen before.
I'd probably opt for the 50mm f/1.2 since it's 1/3 the price of the f/1.05 (£90 vs £260 for the M43 mount) if I didn't already have double-digit number of 50s in PK mount that I use with an adapter (and they're surprisingly good for 30-50 year old lenses.)
(I've got a 7A 10mm f/3.5 that I've not really got around to using much but now the UK is heading into Fake Summer, there's more light to make it useful.)
But I do wish my Sony 50 was a little less noisy/slow. Suppose I should pick up the GM version at some point.
Come on now.
I hate blur, how do I remove all of it?
Or, multiple exposures and HDR.
Smaller sensor, tighter aperture. So yes, more light or a more sensitive sensor.
