lens filters

Archived from groups: rec.photo.digital.slr-systems (More info?)

As a newbie with a brand new Nikon D70s, I am looking to buy a filter,
mainly to protect the lens. I'll be going to the beach and hope to get some
photos there. Is there any filter that is better? I have the standard
18-70mm lens for now. Thanks Mo.

A Circular Polarizer will protect your lens and improve most of your
outdoor shots.

Ditto. A polarizer is great to reduce reflective glare off of water and
improve colour with clear skies, but in reduced lighting conditions you will
probably want to remove it.

Are you using the Tiffen, Heliopan or B+W hot filter? I can't afford the
B+W, can't find a source for the Heliopan, so I'm waiting for my Tiffen
to arrive. The D-70's IR filter is pretty poor, which is why it makes a
pretty good IR camera with a Hoya R72 on the lens.

The D70 is way too sensitive to IR, so your choice is good. I've got the
B+W 486 filters in 52mm and 77mm, and while they're less needed with the
D2x, I'll still use them for people shots, especially in direct sunlight.

Those would not be a good choice for lens protection, though, as they are
quite expensive and take about 6 weeks to get to you. I don't leave them
on my lenses. (I don't normally use any filters for lens protection.)

Mine are all Tiffen, FWIW.

But there is a web site which documents how to remove the IR
filter in the D70 to get better exposure values, so it must do
something. :-)

Enjoy,

My Tiffen arrived in 3 days and costed me about $90.00 including 1st class
mail shipping. I'll probably leave it on the kit lens. It's got a lens cap
on it 99.999% of the time. I didn't put a mark on the UV filter that was on
it for the last 14 months so I'm not too worried.

I just stuck on a UV filter (the lighter variety) for protection and leave
it on all the time. They also make clear filters.

You might also try shooting the glowing coals on a BBQ grille,
at dusk, both with and without the Hot Mirror filter, and see how
*those* compare. I *think* that the shot without the filter will show a
significant magenta shift.

I must admit that I got most of mine used from eBay auctions --
after the first for the "28-105mm f3.5-4.5 D" which I used on the
NC2000e/c before the D70.

Enjoy,
DoN.
