Beautiful image fike!

I'd say the reason most people are told not to shoot directly into the sun is because they may think that if they can get away with it using a wide angle lens, pointing a super telephoto at it may not brighten up your day as one may think. I'm thinking a wicked headache. Smiley Of course the trend these days is for manufacturers to cover their a**es in every ridiculous way they think they need to. Smiley

Cheers,
Jay

Because lens flare reducing contrast?  Smiley

That is the most substantive reason I have heard. It still won't stop me.  Contrast isn't everything.

A few reasons. The already mentioned 'looking into the sun' which can cause vision problems.

Using telephoto lenses magnifies the problems and with very long lenses can lead to burned and melted shutters. Not a good thing for the camera.

There is a lot of scary warnings about stuff like this, but I haven't heard or seen anyone who has actually damaged their camera with too much sun.

It's said that a swan's wingbeat is strong enough to break a man's arm. I've never met anyone who's had an arm broken by a swan.

simply note that your sensor may be damaged.

Not burned, but some areas may have some problems (higher moise, color cast,...)

And you may discover that far later and don't imagine that it comes from sensor high overexposure.

Have a Nice Day.

But as a lot of photographers I've taken shots with sun in the frame Wink Wink Wink

So I am buying what you guys are selling. I have recklessly ignored this recommendation to not shoot into the sun.
And you did well! Very nice image.
I know it sounds quite mundane but... Which lens, please? It seems very resistant to ghosting.

Why do all the manufacturers tell you not to?  Is it because they are afraid you are going to fry your eyeball with a telephoto lens or something?
Frying your eyes through a ground glass seems much less probable to me than simply while staring at the sun with naked eyes, as the visual pain in the latter situation may tell you (once it's a tad too late) ; the ground glass should scatter much if not all of the energy.
Frying the sensor itself would involve a longish exposure, which is not compatible with our sensors' sensitivities : I'd say that the energy level necessary to fill (saturate) a pixel is a few orders of magnitude below the energy level that may fry it.
Frying the shutter seems much more probable, and one may well point that it's the only fact reported hereabove. Wink

For me, the main reason is to avoid complaints about ghosting and flare.
Remember the the EPL2 "red dots" problem? Just ghosting (but way worse than usual, perhaps because it might have been created at the sensor).

Maybe we need a contre jour thread, just as we have one for rocks, clouds & trees?

The brightness of the solar image does not change with focal length, but f-number. A wide-angle lens is not safer.
