My opinion, answering your question is: Yes. The general premise of most of the guidelines seems to be "a useful life".
However, introduced in about 2007 (I think) were "Simplified Guidelines" and in certain cases a (small) business might apply what appears to be a simplified formula of depreciation to (mostly) the majority of (small) assets.
It occurs to me that lenses and cameras are simply tools of trade for a professional photographer: and accordingly taking as an example two tools with a similar life expectancy, one might get less life out of one tool used more often and more robustly or in poor conditions than the other similar tool, used less often and in different conditions.
For example, let's say a photographer has two lenses: EF 24 to 70F/2.8L USM and EF24 to 105F/4 L USM. Let's also assume he shoots a lot of open water swimming - and for open water swimming he is ON the water in a small vessel and uses almost exclusively the 24 to 70 F/2.8 for that purpose.
On the other hand, let’s say he uses the 24 to 105F/4 mainly for indoor functions, such as meet and greet; prize-giving and awards nights.
Let’s assume each lens is “used” for about the same number of hours each year – but the 24 to 70 shoots three times as many frames as the 24 to 105.
Now whilst we might assume that both lenses have a similar life expectancy I don't think there’d be much problem depreciating the useful working life of the 24 to 70 at 24 months and for the 24 to 105 might be perhaps double that period.
I have no idea how the Taxation Laws with respect to Depreciation apply in the UK, (or any other parts of the world) I assume that for every country there will be different rules.
The preceding is not: accounting; taxation or business advice.
Does that answer your question?
