Thinking of something narrower: Panasonic 42.5 F/1.7, Olympus 45mm F/1.8 or Sigma 30mm F/2.8

I'm thinking about getting a narrower prime, for closer crop photos. I have the Olympus 12mm F/2 and Panasonic 20mm F/1.7. 30mm is a little different to 20mm and will give me 60mm instead of 40mm, the other options are the 42.5mm and 45mm which are just about the same at around 85 to 90mm, or there abouts. The Sigma is the cheapest option.

I've discounted the Olympus 60mm and 75mm options as they're really too long for indoor use, I've tested it out with my 14-42 at 30mm and 40-150 at 45mm, I can't really decide. I've got a slightly obscure normal lens at 40mm so I could go with a 60mm or an 85mm or 90mm option. I really can't decide, the Sigma option is very cheap, and I like a slightly wider lens, but it just might not do it for me.

Don't discount the Canon EF 40 2.8 STM with Kipon AF adapter.

No AF-C but in that regard it is just like an 20 1.7 on a GX7.

But not at all like the Oly 45 or Pan 42.5 - the lenses Hithertoo is asking about.

The adapter will cost twice as much as the lens but together is still not THAT expensive and the lens is VERY sharp at 2.8 and makes a nice portrait lens on M4/3

The Pan/Oly lenses also are very sharp wide open while also being 1.5 stops brighter. No compelling reason for this combo unless...

I think while still being useful on both FF and APSC cameras.

...you also have Canon cameras...

The Kipon adapter with this lens is now quite useful with firmware 2.5 as there was a distortion issue that has gone and AF (AFS) is quite fast ....at least with a GX7.

...which Hitherto's gear list shows is not the case.

The Canon/Kipon combo is bigger, heavier, more expensive, and lacks C-AF. Is there some other reason to consider it?
