Handling \/ Build quality<\/h2>\n

These lenses are almost the same. I always have to look at the aperture ring to be sure to pick the right one.
\nOnly difference: the focus ring on the 25mm has less resistance than that on my 21mm and the spacing between 2m and oo is a bit narrower on the 25mm which made precise focusing at infinity a little harder with this lens.<\/p>\n

There are almost no non moving parts to grab to mount or unmount the lens, if this is something that may bother you have a look at the Loxia Lens-Grip<\/a> from PocketPano.<\/p>\n
