.... This is why many of us keep our most expensive lenses locked away and hardly ever use them, and never outside....


It's a fact...

Yes, it's already starting to turn stale. All that dry air in Botswana has accelerated the process.

What, does she own a camera store? Is she heavily invested in Canon shares? Maybe she's trying to make a sale.

Why would a lens go bad after 3 years? There's no expiry date on glass. If there is, it's way longer than our lifetimes. Yes, technology moves forward. Yes, there's better glass available now then there was 20 years ago, but it doesn't mean any of your current lenses have somehow gone bad.

Is it possible that she's talking about the tax value of the lens in a business?

I don't know the details, but I think you can get tax benefits/discounts/wha​tever for assets and the value of the asset deprecates each year till by the 4th year you no longer get benefits.

In that case it might make financial sense to sell the old lenses and buy new ones - gaining both newer models and a tax benefit?

That would depend on how your business is set up and how you are deducting business expenses. Normal "business" expenses can be itemized for 3 years, but hardware can be depreciated by 5 years. Then what would get complicated about selling your old stock to get new stock to depreciate: your financial gains in selling your old gear should be reported as income. So in simple situations, it doesn't make much financial sense. I've been self employed as a medical animator. I would do itemized deductions on any computer hardware, but got most my deductions through office expenses, conferences, and education material.

The sister in law should be more specific about what she means. If she did mean the value of the lens depreciates (or tax reasons), then there may be reasons. However, the value of lenses certainly doesn't depreciate the way camera bodies or computers do. I still have a Canon AE-1 and FD mount lenses (30+ years).:rolleyes: Looking through the lens, it doesn't look mushy.:-)

Yeah, I don't think even depreciation makes sense here.

I don't want to become known as the POTN Brainiac, so I've avoided posting that she is ABSOLUTELY right! Someone hinted at it above: glass is a liquid. As such (duh!), it flows. If you look closely at some of the early European church glass windows, they are becoming distorted after standing in place for 500+ years. The glass in your lenses will do the same. If you leave your lens laying on its side, all the glass WILL flow to the downward side in... let me estimate here... Oh, maybe 5 or 6 million years. But, and this is the point the lady is aware of: IT BEGINS AS SOON AS YOU SET THE LENS DOWN! If you stand it on the objective end, things will sag that direction and you will soon (500,000 to 600,000 years) have noticeable pincushion distortion. Stand them on the projection end and you will have, just as quickly, barrel distortion.

All is not lost, however. The real secret, and much cheaper than buying new L-glass every three years, is to store your lenses in a casing polisher. Here is the largest one I could find: https://ads.midwayusa.​com …0N2gfEEAQYBSABE​gIyvvD_BwE (external link)

That one should easily hold a 70-200 2.8, or a 100-400L. If you are fortunate enough to be able to afford BIG glass, you'll need a big tumbler. This one holds up to 300 pounds so you can do all your long glass at the same time: https://www.northernto​ol.com …0wIQnDEAQYAyABE​gLgWfD_BwE (external link)

These things may seem a bit costly, but remember, they are saving you from having to replace all you glass every three years! You are welcome.

For the L-addicts, who simply must have the best, take a look at this one!: http://www.mixertrucks​.com …rete-Mixer-Truck/?id=2635 (external link)

EDIT:
Someone help me, please. I have way too much time on my hands!

Oh well for scientific conversation: glass actually isn't a liquid. It isn't a true solid either: it's considered an amorphous solid. There are older glass examples from Egypt that do not have any kind of sag to them. It's thought that the reason medieval glass might look to have more mass at the bottom is either intentional or the glass making methods weren't to par.

Fact or Fiction: Glass a Liquid? (external link)

I think what really muddies the water with camera lenses is that when they're being made, they're also not pure glass but have mixtures/coatings of elements like fluorite or quartz. So with modern technology, it might be more than 500,000 years from which you set the lens down in which there will be noticeable distortion. Then again, what if you set the lens down, and in a few hundred years, biological contaminants start having their way....maybe instead of just a tumbler, you should also autoclave from time to time;-)a

Great response! If you can't afford an autoclave, a large pressure cooker can accomplish much the same thing.

For a time after college, I worked at a company that manufactured ethylene oxide sterilizers. Horrible, horrible stuff (toxic, explosive, carcinogenic, etc) - but it's what you use when you need to sterilize endoscopes or things like that without burning them up in an autoclave.

New market for fungus-filled lens rehab?  :p

Ummm...not quite.

Tax Pro here. Depreciation is too complicated an issue to address in a comment in photography forum. Consult a tax pro for advice specific to your situation.

Depreciation is a deduction that allows taxpayers to recover the cost of tangible property over its useful life. In general, costs of tangible property must be deducted over the life of the property. To determine how much you can deduct per year, you take into account a lot of factors, including the class life of the asset. The class life of photographic equipment hasn't been designated by law, so it falls into the catch-all seven year property class and may be deducted over seven years. (Computer equipment has been designated as five year property). Your asset may be eligible for a more advantageous deduction rather than spreading the cost over seven years. It may be eligible to be expensed (deducted in the year it is placed in service), it may be eligible for special bonus depreciation, or it may be eligible for a Section 179 deduction where the entire cost of the property is deducted the year it is placed in service. Again, consult a tax pro.

As for "normal" business expenses being deducted over 3 years, I'm not sure what you mean by "normal." if you are a cash basis taxpayer (like most self-employed people), you report income and deductions in the year that they are actually received or paid (not including depreciable property which is treated differently). Also, when you say you "do itemized deductions", are you using the common definition of the word, ie listing items separately? Or do you mean you are deducting your business expenses as a personal itemized deduction on Schedule A? The latter would be a no-no.

You are correct that the sale of business assets results in income. If you trade in your old gear for new, it may be eligible for a "like-kind" exchange and some tax savings.

Well then you should know that 3 years is considered the most conservative and common property depreciation, 5 years for computers, office equipment, or cars, and 7 years for property that can't be placed in other category. The gist of my post wasn't to get into specifics of tax law: just showing how under normal circumstances, I don't see how selling claimed depreciated lenses for new ones gives any financial benefit (from an ordinary tax point of view). If you want to question my tax history, I am conservative and itemize equipment during situations it makes more sense then including in the standard deductions.

I'm sitting here trying to figure out how that is relevant. Do lenses really only last longer than 3 years in the US? I've taken some of my lenses to Germany and England. They seemed OK.
