Thanks for the kind comments, all. Ollie – having just Ebayed a Nikon 18-55 VR, I’ll keep a look out for the 70-300.
As my wife is pestering me to “get rid” of my endless masses of old photos I may have a bit of a scanning session an upload some vintage shots soon. I am a bit wary, though, as I’ve not looked through them in a while and they are all taken on the very-manual-focus T-70…….
