I was mistaken about equivalent exposures on the EXIF data. Now that I
take another look at it I see that they both have the same aperture but
the 21mm has a 2/3 stop greater exposure than the 35mm. It's 1/3 stop
more sensitive on ISO and 1/3 stop greater exposure time on shutter
speed. I'd have thought the exposure bias would be in the opposite
direction. I'd expect the wider angle lens to see more sky and give the
scene less exposure. From the EXIF data:
Focal Length 35 mm 21 mm
Exposure Time 1/125 sec 1/91 sec
Aperture f/4.8 f/4.8
ISO Equivalent 160 200
