Dear C-Hing, hope this photo is up to your expectation la,
it is a very good lens, focus ring is very smooth (not loose), with
good resistance and not tight, good build, but won't be water proof,
it is indeed hard to use, and won't be used often, and if you want to use it
for travel since it is 24mm, (think twice), because if you ask someone who
knows just little about how to use entry level DSLR, will have difficultly taking
a picture for you when you hand it over to him,
my experience is no one knows how to use it when you hand it over,
it takes time to learn the basics of this lens, and takes a little less than a life time
to master it, hard to perfect, but sure is fun, I wish I could have a PCE-85 f2.8 someday,
as it will be the best prodcut lens there is to own,
I will just a few more picture of this lens with it in Tilt and Shift position,
thank you so much for viewing,
I really hope my picture could explain a little more than with is given by the catalog, as it does the least of giving anything worth reading.........
sincerely
