The 70-200 f4 is underappreciated. It's a great, sharp lens, and a bargain at about $500 used, if you don't need the IS model.

I've been shooting with the tamron for a while. its a great lens. no I would not dream of trying to shoot HH at over 100mm for most things. a real tripod / head / follow focus is required. that said, the tamron is internal zoom / focus so your matte box can stay put. thats a big help. only minus to me is the focus throw is short, maybe 90 deg or so, which even more mandates a FF to get some control back.

how you getting on with the Tamron James - has it been worth it?

Not had it out on a wedding yet, as soon as I do I'll post my thoughts.

Havent had time to put all my new toys that I got in NYC to the test as as soon as I got back, straight into making a dent in the stack of weddings to get edited.

Prob another week or two before I get some proper time to test them.

The main testm I'll be doing is actually audio, got the zoom, the tascam, and the juiced link, will test all 3, pick my fav, and sell the other 2.

Again, will post my thoughts on all my new toys :)

ps, i have used my new sigma 30mm 1.4, love it, focus ring is bit 'rough' though, not as smooth as say the canon 17-55, or the tamron 70-200, or the tonika 11-16.

But I'm loving it for low light meduim wide shots
