I agree that f/4.5 is fine for many situations. It's mostly indoors and in the street at night that the exposures get a tad long. I will try pushing the film at some point. I'm afraid I have a sentimental attachment to the Aero - did some cool astrophotography with it as a kid. I suppose though I might find a loon on the auction site that would give me $1000 for it!
