Canon EF 35-105mm f/3.5-4.5 lens on a Canon EOS 30D camera. ISO 100; f/8; 1/250th; lens at 35mm (field of view equivalent 56mm).
I am working within the limitations of the focal lengths provided by this lens. I very much like the lens and wonder if I would like it just as much on a full frame camera. Two factors hold me back. First, I'm not enthusiastic about wide angle photography or getting up close and personal; I've always favoured the telephoto end and you get bags more of that from a lens on a crop sensor camera. Secondly, even an old Canon EOS 5D dating from 2005-2008 (the original 5D) costs around £300 secondhand and is a depreciating asset. The 30D I'm using now was about £70. So I think I'll continue as I'm going.
