Connect a Nikon D50 to a Centon F. H.4.5 flash?

I have a Nikon D50 that i recently got as a present for my birthday and i have a Centon F. H.4.5.flash that i have had for years. I was wondering if there was a way that i can use both of them. I have heard about a TTL, but i don't know exactly what it is or what one i should get that would connect the two.

Not familiar with your flash, and Google isn't either.

So, some general guidelines…

If your flash has a standard hot shoe, it will mount on the camera. Simple enough. What it does after that, I can't say, as I don't know what kind of flash that is.

I can almost guarantee that it is not a TTL flash unit. TTL means "through the lens", meaning the camera measures the flash output and controls that output. Each camera maker has their own version of a TTL flash system, and they are not compatible with each other. Your camera uses a system called i-TTL, older Nikons use D-TTL, Canon uses E-TTL, Sony has ADI, and so on. Each is different, and incompatible with each other.

Your flash is probably either a manual flash, meaning you have to control the power settings yourself, or an auto thyristor unit. Thyristor flashes have a light sensor on the front, and use that sensor to measure the light reflected from the scene. Either type requires that you shoot in manual mode.

Some will get on here and tell you that the flash will fry your camera because the trigger voltage is too high.
