Has also been done with a K10D

I think their land management is quite good. Without it the South West coast path would be impossible as there would be too many private land owners not wanting open access. Same in other parts of the country.

+1 for Arctic Butterfly in 4 years with a K10D only once have I done a wet clean thanks to mine.

That works so well!

Did the SR compensate for panning or did you have a tripod?

It is a dust mite living on your sensor!

I think it is a weather balloon really.

It does depend on the job though. For example doing school portraits with hotshoe flashes would be daft as you would run out of power or blow the flashes up given the numbers and time constraints.

Where portability is key compact stands and hotshoe flashes win out. The 58s give me an average of 600 flashes on a single set of eneloops with recycle times under one second for most power levels. It only goes up when using anything above 1/4 or as the voltage drops (the real killer) and that is after a good 400 pops.

I really didn't think my last post through though.

I'd add some isopropanol for cleaning off the vinegar as otherwise it will leave a sticky and conducive residue.

Free parking and entry to all NT and Scottish NT properties. I think it OS rather good value considering a single visit can set you back £10 easily. Make 6 or 7 visits and you break even, make more visits and you're laughing. Couples memberships are even better value as they are £85ish. Luckily me and my wife still come in as young people so that is about £23 each.

Why buy huge studio flashes when I can achieve the same with a bunch of off camera hotshoe flashes?

DVD-RAM is fully rewritable and can be done real time. You don't burn DVD-RAM disks like any other DVD. They act like a slow hard disk. Nothing thrown away!
