Great cgrindahl 2004-10-29 18:31

I hate to break the news to you Elroyie, but there isn't a lens on the market long enough to get a "closeup" of the sun... ;-) My calculation tells me that at maximum length for your lens you are out at about 896 mm with the converter. Perhaps you need to buy one of these zoom lenses.

Humor aside, you did well, in capturing this dramatic image. I find interesting the fact the sun appears to have been compressed from top to bottom, no doubt an illusion created by the earth's atmosphere. The colors, of course, are very stunning, created unfortunately, as you note, but air pollution. This is one of those rare occasions when we can be grateful for all that particulate matter... ;-)

Well done Elroyie!

Default To cdewet: Deformation

Hi Callie,
The deformation of the circle shape of the sun is caused by the long way that the light has to go through the atmosphere when the sun is low. There is a difference of the atmosphere "thickness" between the "lower" and the "upper" sides of the sun, and therefore, the effect is not equal for those parts.
It's a great shot, Anyway.
Y.

Default Re: To Yitzhak: Deformation

Hi Yitzhak
Yes, I am aware of this, But I have never seen it like this until recently. All my previous picures had the sun round, evem on the horizon. I think it is a function of teh Didital magnification. Even the edges of the sun is ragged on my pics as well.
Regards
Callie

Hi
I saw that Yizhak answered your question so I didn't interrupt, I have an example of the sun without the converter, it is also not round and the atmosphere is the right explanation, it is hapenning when the sun is 'kissing' the horizon, here are an examples:

I think that the wheather at the shooting moment has also influence, like humdity and more.

Another point, I think that the converter is adding a little bit CA to the pictures, you can see it around the sun, there are a little bit coloured edges.
