I've two new Fujicrons, a 23 and a 50. For you who are not Fuji-cognoscente, the name is a play on a line of Leicas, the Summicrons. Anyway, point is I've two new lenses and I used one to take a picture of the other, in this case the 50 was used for a shot of the 23.
Oh, that's an HP 16C, my fave calculator, on the left, for size comparison.
The two Fujicrons look similar, the 23 is just a bit shorter than the 50 no surprise. So far I'm happier with the 50 but it's early and I think I need to test them out on a trip.
