I suspect rapid sales decline, well certainly in photographic products anyway, although i wish so much that manufacteurs would put the price down on their product, that little bit, so that people 'on the fence' would just get off it! Also i believe in enthusiast and ameteur terms, photographers are 'holding back' on buying kit, because they know, if they wait, they can get it for a cheaper price, in some cases hundreds off the current price! I am certainly following this principle, and am sure others here on the forum, are too!
I wouldn't hold your breath waiting for prices to fall, at least not here in the UK.
Unless you're lucky, most of the stock you'll find on the shelves has been bought-in and paid for recently, since the dramatic fall of Sterling.
If the dealers have had to open a vein to pay for it, there's no chance of them offering it for sale at anything less than top dollar. Those that bought before the demise of Sterling are going to want to maximise their investment to cover escalating costs. It's a lose - lose
situation for the consumer.
Here at home (UK) we can expect to see taxes and
interest rates rising very steeply over the next few years. If, (and that's a big 'if'
) the economy eventually stabilises, don't expect to see the prices of so-called 'luxury goods'
falling, they wont. Don't expect to see taxes falling back either.
If the doom and gloom merchants are to be believed, people are going to be selling, or eating, their own children here during the next five years. I don't think it will be quite that
bad, but it will be bad.
That said, there's going to be a lot of bargains out there on second hand kit.
But, if you've got the money now, you want new stuff and
you can afford to do it, buy now.
