<p>Hi Daniel,<br>
I would recommend the FDn 2/35mm. Rumors say, that older versions should be slightly better, but as I sayed, rumors, and, because of the age, possibly more issues (e.g. yellow tinting because of radioactive elements). The lens is not cheap. Should be well maintained and adjusted to the body for perfect performance. 35mm are very versatile for many duties. Use of the lens hood BW-52A is mandatory.</p>
