Dear members:
Is it important for a dc to have a TTL Flash?
If the dc without TTL Flash, is it a big problem ?

Without TTL, you should be turn the Brightness with your hands.
Sometime you take the photo, that may be over or lower.

It would be a problem.

Thanks for your reply ,but I have some questions .What do you mean of brightness ?
Do you mean that to adjust the size of the aperture or do some setting directly from the external flash ?

If no TTL, u still can use auto by the flash. Its not convenience as TTL but still so accurate. U need to set aperture of the camera & the flash. By the way, auto by flash doesn't have so many advanced features as TTL.
