I wish they'd knock a couple of grand off the Sigma 500mm 1:4.5 lens. Not much chance though.

That reminds me, I haven't watched "War of the Worlds" for a while

There are free Excel Templates available that should help with simple accounting needs. Your son's accountant may already have one or more templates that he/she would prefer to be used. No point in reinventing the wheel when it's been done so many times before.

To keep track of cash I think you only need three ledgers to show sales, purchases, and bank account.

That said, Sage Instant Accounting is very good and preferred to Quickbooks by many accountants.

Here's a link to the manual. In the specifications it just makes a reference to an optional 6V adapter.

I thought I'd have a go anyway and yes, it's your image

Then I had a play

I tried it in LR4 but couldn't get close to DrO's image quality.

If I'm walking around a city or town, 12-24 or 16-50.
Walking in the woods, 60-250, 300, 150-500, 180 macro, or 100 macro.
When I go out not knowing where I'll be walking, I take them all, and more.

There's no 'one size fits all' lens for me, but the 18-250mm would cover most of my needs except for tight city landscape shots, if I had one.

I think most, if not all wireless triggers are generic, that is, they all work with everything (in theory anyway). With some, you may not get full synch shutter speed.

You'll not get P-TTL or TTL control with them because they use only the centre contact of your camera/flash, so you'll need to learn full manual control of your camera and flash setup. The flash meter will help you a lot.

At the top end, you have Pocket wizards preferred by many professionals, but they are very expensive. I use Seculine Twinlink products which have the benefit of both IR and radio triggering and work up to 100 metres outdoors. A popular option is the Cactus V5 system which I believe can also be configured as a wireless remote shutter.

I had a bad experience with the cheaper PT-04 type and cannot recommend them, but I know others have had good experiences with them. I had one transmitter and 3 receivers. Within 6 months, two of the receivers died and I switched to Seculine which have never misfired or let me down.

Looks like he's looking at what he's just stepped in.

My apologies, I totally forgot that the DS uses AA cells, and you are correct, they are wired in series to provide a nominal 6V (4 x 1.5V) with Alkaline cells.

Have you tried a fresh set of batteries? It's probably worth buying a set of 4 Duracell Ultra's or similar just to eliminate battery issues.
