Not a great deal.

I’ve bought a Sigma 24-70mm F2.8 EX DG Macro lens for my camera. It cost £300 in the end. I’ve had a quick experiment with it this afternoon even though the light’s not wonderful outside. It does amazingly sharp macro photography.. when I can persuade the D70 to actually focus on the tiny thing I want (instead of somehting behind or nothing in particular) and stay still enough to keep at the correct focusing distance (which at F2.8 is a problem because there’s almost zero depth of field) when pressing the shutter button and when the wind stopped and the bush/tree with the lichen came to rest. 🙂

What did surprise me was how big and heavy the lens was. It’s about double the size and three times the weight of the Nikon 18-55mm DX lens which came with the D70. It’s Huuuuuuuge!

That’s about it, really. I’m off out to listen to the choir a friend sings in (Commotio) tonight at 8pm in Merton College Chapel. The last concert was quite nice and melodic, I’m not sure about this one. They do contemporary music you see and some of it can be quite “interesting” and non-melodic. Anyway, Katie was pleased with the large version of their CD cover I printed out so as to advertise their first CD in Blackwell’s.

[update]
You can see my experiments here. Ignore the tennis ball shots that was another experiment I did last Sunday with contrast in sunlight.
