Nikkor 14-24mm/2.8 --- fire in the hole?

[arthuryeo]

I almost broke up into laughter when I was reading the manual of this lens:

<blockquote>"In backlit shooting, keep the sun well out of the frame. The

sunlight could focus into the lens body and cause a fire. When the sun gets

close to the frame, it can also cause a fire."</blockquote>

<p>

In other words, don't let nasty sun sneak close to the lens. :)

<p>

For those of you who has the Nikkor 10.5 fish-eye or other super wide primes, do

they come with such warnings? Just curious ...

Never had any problems with the lenses burning or the cameras burning.

But these shots were taken using simple and inexpensive prime lenses.

<p>

I am fairly certain that none of these lenses use any scotch tape to hold them together either! :)

I'd only worry about it if I found a way to mount the lens on a Leica M. :-) Hopefully, Nikon won't be putting cloth shutters into their bodies any time soon.

[ben__evans]

Not that it would matter with a mirror in the way for most of the time...

 

By the grain in some of those shots you must have had to bring up some pretty dark shadows so the exposure time can't have been too long. However, is there any risk to the sensor for a slightly longer exposure time?

[ilkka_nissila]

Maybe this lens is just so sharp that it renders the sun as a small spot in the sensor, blasting it ;-)

70-200 f/2.8 comes with the same warning. (For outdoorsy, survivalist types: Can a fine lens do double duty as a campfire starter?)

[dan_brown4]

On a DX body the sun could focus around the periphery of the mirror, and set the mirror

box and frame on fire.

 

If possible, avoid oxigen rich environments.

They do not allow this lens to be used anywhere near the space shuttle booster rockets as its being refueled and there has been several cases of spontaneous human combustion when using this lens while drinking alcohol.

OK, no Martinis when using Nikkors from now on and carry fire-extinguishers. :)

OT: Vivek,

Two of my Nikon lenses, the 85/1.4 AiS and 135/2 AiS, actually do use scotch tape as part of

the design of the lens to hold the infinity focus setting. You can see it if you peel back the

rubberized focusing grip. One of them I purchased new, so i know it wasn't an improvised

repair from a previous owner.

[vivek iyer]

Keith, Thanks for that info.

 

I think, I should consider Nikon's warnings a bit more seriously! :)

Kent - "For outdoorsy, survivalist types: Can a fine lens do double duty as a campfire starter?"

 

Only in a survival situation, not as a standard operating procedure. The smoke will damage the coating on the rear element of the lens, as well as coating the contacts. It can also work its way between elements, condense, and cloud a lens to the point where you have to have it professionally torn down and cleaned.

 

And yes, I do know these things from personal experience. ;)
