I recently bought a Panasonic gx7 and the Panasonic 14mm f2.5, and I also have a couple of old Olympus OM lenses (28mm f2.8 and 50mm f1.4) I'm looking to get another lens the question I have is wether I should get the Panasonic 20mm 1.7 or the Olympus 45mm f1.8. Which lens would be a better buy for me (I mostly do street photography and landscapes)

I have both plus the 14. The 20 is a bit better for the street.

The 45 has, by design, field curvature which makes it not so good for landscape but it is good for portraits. Others suggest the Panasonic 42.5mm f1.7 instead of the 45.

My suggestion if you want something in between, is the Sigma 30mm f2.8. I also have this lens and it is very nice. It will be better than your old Olympus 28 f2.8.

But the OP mentioned in a later post that low light and depth of field were big concerns. That makes f2.8 no so good. If it were okay, I’d opt for one of the f2.8 zooms, not an APSC designed lens with a M4/3 mount.

Have you actually used the Sigma 30mm f2.8? it is quite small and very good IQ.

Over Christmas I did a lot of night street photography with my 12-40 set to f2.8 and it was just fine.

So f2.8 is not a limitation.

As you can see above, I responded to the OP's request for the two mentioned lenses and also gave an alternative. As did others

So, how come you did not flag the others who gave alternate suggestions?

Hi!

What does flagging mean? Your comment come from notifications. I have not read whole chain which is, of course, bad habbit. But original question was pretty clear. 20 or 45?

You are right though, there would be plenty of lenses what to suggest: Sigma 30/1.4, Oly 25/1.8, Oly 17/1.8, Oly 12-40 you mentioned, plus all the Panasonics...
