This is going to be subject to your tastes and where you shoot. The kit lens might be wide enough. If not, then the 16mm with the wide angle converter might make you happy. There are not a lot of choices with AF unless you get the Alpha mount converter. I prefer going a little wider than the kit, and recently purchased the 16mm with the converter. But I've not have time to test it much. I also want to try my 12-24 Nikkor on the 5N. I've seldom wanted anything wider than the 12-24 on a 1.5X crop sensor.
