Hmm lots of lenses, 35 years and some tips.
1. Lenses that I use a lot...
Zeiss - 21/2.8, 25/2, 28/2, 35/1.4, 50/2 MP, 100/2 MP.
Canon - TS-E 17, 70-200 II, 400/4 DO
Occasional use - OM 55/1.2, 8-15L, OM 16 FE
2. Time behind the eyepiece - 35 years.
3. Tips
a. Get a full frame camera
b. Get a 28mm manual focus lens (say an OM 28/2.8 ) and a really good adapter. Fotodiox Pro is the one to spring for.
c. Learn to visualise what's going to be in the field of view, how to estimate your exposure and how to position yourself to get the best composition. Once you can do these things without thinking, you are ready for a second lens. I'd get a really good 50mm - Zeiss are bringing one out in about a year - that's about the right time frame.
d. It takes time to learn what a lens can do. DONT buy too many lenses at one go, even if you can afford it. One or two lenses a year is probably about right.
e. Take lots of pictures, take notes too, read them from time to time.
f. ETTR about 1 stop and pull it back in post.
g. Start a flickr page and use it to see how your technique is improving.
h. Look at other photographers images and see whether you know how to do what they've presented.
i. Learn to use Lightroom, buy the Nik Software bundle.
j. PRACTICE and HAVE FUN.
