Thank you David.
I see there's more to focal length measurements than I realised!
Yes, a simple rule is that with cameras like the D40, multiply the optical
focal length (the one on the barrel, and the speicifcation) by 1.5 to get
the equivalent filed of view, so the 18-55mm kit lens has the same FoV as
a 27 - 82mm lens on a film SLR, and the 70 - 300mm lens has a 105 - 450mm
FoV.
Not sure which 300mm lens I'd go for, but likely it would be a good
Nikon one). Bit vague on that!!
I think I'll consider playing with the D40 (or D40x) and a Nikon 300mm
lens without the teleconverter first to see how I get on.
Many thanks indeed.
Greg
The 70 - 300mm VR lens is excellent value for money and good optical
quality as well, not too heavy - useful if you can get close enough to the
birds!
