Newbie question about lenses

[Birger Aune <BAU@xxxxxxxxxxx>]

Hello everybody

I have a question concerning lenses and focusing for IR-photography. If I
use an apochromatic lens, will I then have to adjust the focusing when
using infrared film ?

I guess this shows that I'm quite new to this, so I've included a short  bio.
Name: Birger Aune
Profession: Chemist transformed to computer consultant
Country: Norway
Personal History of Photography:
Active amateur for the last seven years (no intentions of going
professional).
Preferred subjects: Landscape, architecture and still lifes. Getting more
into detaoils in landscape and architecture as time goes by.
Materials:
Mostly Agfa films and papers, but very open to try/test new things (but
where can I get another 24 hours a day ?)
Format:
35 mm, building a large format camera (4x5)
Other hobbies:
Cooking and Motorcycles.

I found this list after looking at George L. Smyth's home page.

I don't have a web-page, but some non-IR images are posted at
http://www.obscuar.no/klubber/okk/html/galleri.html. The web-site is in
Norwegian, and the URL is for the galleries of Oslo Camera Club.


mvh
