does it get worse when you alternate between pointing at dark and light objects?

I don't think I've had quite enough time to say since sometimes I can't get it to happen at all but when it did, I got the feeling it was more pronounced When going between light and dark areas.

If so this is perfectly normal and not something you need to worry about, my EM5 does this as well to keep the sensor from blowing out when pointing a fast lens at a bright light source. Its particularly noticeable with the Panasonic 25mm 1.4 as it has rather loud aperture blades, but in reality its harmless.

I just got the two primes a little while ago and had only used them for low light shooting.  Today was the first time I had used them in bright daylight.

Thanks for the responses, really appreciated!
