This is exciting news, Alfie! Where are you working as a photojournalist? We
knew you were thinking of giving up your day job for a career in
photography, but you had asked about various photojournalism programs - I
remember something about your asking about MIT - so I just naturally assumed
you were going to go to grad school and then head out into the field. But
now you're facing bayonets? Wow! Where was that? It must have been pretty
hairy!

As to filters, since the Promasters didn't degrade the images produced by
your Nikon lenses, I wouldn't think there's any reason to switch to a really
high-end filter such as Hoya.

But Jim Brick is the real expert on the use of filters to protect lenses -
he has particularly strong opinions on the use of UV filters - so you might
ask him to weigh in.

Hi Leica folks,

A few summary questions:

1) If I buy a Leica lens with a dented filter rings, how much would it cost
to straighten it out to install a filter? Would it be fairly complicated?

2) I was wondering whether a filter on a Leica lens can "degrade" the lens
resolution and image and increase vignetting. Perhaps this varies among
filter brands from Promaster (lower end which I use without too much
trouble, used on my Nikons previously) to B and W, Hoya, and Heliopan which
are multicoasted and very exceptional. Being a photojournalist, I need the
filter pretty much all of the time since I work in rough spots and can't
spare my lenses to the potential abuse (or poking fingers and bayonets).

3) Do you use a filter on your Leica lenses all of the time, some of the
time, or never! If not at all, I guess that you keep the cap on in that
case?

4) I know that a UV filter can increase flare but in most cases the hood has
been totally helpful in that respect. Unless you're a sour Noctilux fan
here.

5) Which filter brands do you recommend? Or experienced? Or hated? Or
disrecommend?

Thanks for your commentaries and hopefully some positive enusing can occur.

Alfie
