Hi all.
I am seriously thinking to invest more into lenses, and i have considered the 17-40 L to fit on a 10D since the 1.6 factor provides a usefull and usable focal range (27-64mm equivalent)
However, i have never used a 35 mm camera (i have started with the D30) so i was wondering what would be the value of such a lens if i switch for a future canon body which will have a full frame sensor? 1.6 * (17-40) seems to be a usefull focal range, but what about a real 17-40 mm (especially 17 mm)?
Another solution would be the 28-70L but in this case the problem is the opposite and the minimum focale of 45 mm would limit the wide angles on the 10 D (i think in my case, i would really miss the wide angles).
Any thoughts that could help? (excuse the poor english)
Thank you
Dan
