On a real world subject very often it will only be very slight and may even help the image a little. Of course it won't help if we crop the image.

I think the real problem would be keeping the relatively prominent mirror clean enough. We think we have dust problems now.......?

If the cards are any particular age, the a new one may be OK. Also, don't forget to format the card in the camera every time you want to delete all the images. If you don't there is a small risk of card failure.
Hope that helps!

The Pentax 55mm f1.8 lenses were pretty good for this, so I hear.

The 50mm f/4 was a dog

From the unpredictability I've now seen, I'm really only concerned about the apparent asymmetry, since this might suggest that the optics haven't been assembled quite right.
