Anyone get harsh shadows with a 10mm lens??

[Kristian]

I've got a Sigma 10-20mm lens.
At night i just use the flash on the camera and most of the time experience a harsh shadow which seems to go from bottom left to bottom right.

Anyone got any ideas?

The flash is not able to cover the angle captured by the lens. You also can have problems with the lens blocking the flash. You need some type of 180° flash to cover such a wide angle of view

Pop up flash is no bueno. My Sigma 10-20mm works fine.

It must be the flash because i dont get the shadows without using it.
I have a larger one, i'll try that out.

Its the wide angle of the lens thats all, I get them with my 11-16mm tokina as well.

If you have an external flash, see if it has a bounce card or diffuser to help spread the light. If it doesn't come with either, get a Sto-Fen Omnibounce (cheap and small) or a Gary Fong Lightsphere (much better IMHO, but looks goofy and is bulky).

This happens to me whenever I use the fisheye even with my external flash (which is a shitty sunpack). Wouldn't a diffuser help out with spreading the light?

 

[PRND[S]]

Yes, but the diffuser will eat up quite a bit of the flash power, so you either need to crank up the power, ISO, or live with a shorter flash range.

The diffuser built into the flash may not be able to cope with the extreme field of view of the fisheye. You may need something like the Omnibounce or Lightsphere which can spread the light much further.

It has less to do with the lens then with the Flash power, camera settings, distance from subject and situation. It's a combination of these settings. If you don't want to get an external flash you should try one of these: Gary Fong Puffer, but there are cheaper versions also. Also play with bouncing flash if you get an external one. I find that the diffuser (Stoffen-type) do not "eat up" enough of the flash power. Even at 1/128th power it's still too much.

Not shooting Auto/AV helps also, not sure what mode you shoot in.
