Very happy with our Neewer TTL flashes. Godox and Yongnuo are also good budget choices.

I love my Nikon SB5000 and my SB910. Nothing negative to report at all.

Tommy II Loc: Northern Illinois

👍 I second that opinion. Works great on my D500, and the cost was minimal ( if you can still find a used one).

I have an old SB-600 that I use with my Nikon cameras. It does the job for me.

The OP doesn't say what is not so good about the SB5000.

There are many, many, made in China speedlights that will work, and work well. If you want to stick with Nikon an nice used SB-800 would serve you well. About every month or two I put batteries in mine and shoot off about 5 flashes and leave the unit fully charged, take out the batteries, and do it again in about a month or two, keeps the capacitors formed.
The neewer speedlight listed below is an Amazon choice. It is inexpensive, I have used it and it works fine.

If you want to RIDE WITH THE BRAND, an SB-800 or SB-900, or SB-910 are all excellent choices and are available mint from ebay. The following is an example.

No matter what you choose a tilting head is a must. It is easy to take nice flash shots inside. Here is a great recipe.
1. Camera on manual. Start with like 1/60 to 1/125 sec. at an F stop a couple of stops down.
2. Flash on TTL
3. Attach flash
4. Aim flash head up and behind you at about a 45 degree angle.
5. Take a quick test shot and adjust from there. easyie peesie

Thanks for all the info on the Godox flash units. I'll have to see if they have a model for my Pentax cameras. Nikon and Canon obviously!

I have a D7200 and a marvelous pair of SB 700s. They work great, close and far.

I recently bought a used SB-400 to use as an "emergency" flash, since the D850 does not have a pop up flash. I've been playing with it and believe that it will be useful for those times when I need some fill flash or it's just too dark for even the D850. It is a decent flash, with an ISO guide number of around 98 at ISO 200. It performs automatically and the head can be adjusted to bounce vertically. It will cover something likek an 18mm lens on a full frame camera. But it sits very low, and a lens of any size is likely to vignette, especially at short focal lengths. (It is fine with the 24-70 f2.8 at focal lengths greater than somewhere around 30 or 35mm.) It has no controls other than the On/Off switch and seems to get about 130 or 140 flashes from a pair of AA alkaline cells. Rcycle time can be around 3 or 4 seconds if it is operating near full power. The only thing it doesn't solve for me is replacing the focus assist light that the D850 doesn't have. It's also supposed to work with the Nikon Creative Lighting System, but I haven't tried that yet. Not sure what the functionality could be, beccause I haven't found any IR sensors yet.

For more intentional use, I still have a pair of SB-800s that I bought years ago. They have an automatic zoom head and will cover down to 14mm with the diffusion dome that comes with them. They will also use color filters and other accessories if you are into fancy flash stuff. These were replaced in teh lineup a number of years ago, and I don't see a lot of used ones for sale. They work great, especially on a bracket.

I must write off the OP as a troll! He said the SB5000 isn't very good but not saying why. In general the SB5000 is the best flash for the Nikon D500 unless someone has a special need.

GoofyNewfie Loc: Kansas City

They do. Sony, Olympus/Panasonic and Fuji as welll.

lamiaceae Loc: San Luis Obispo County, CA

Could be, even I've heard that and other Nikon flash units are great and I'm a Pentax user.

Bill_de Loc: US

He said he read some reviews. If you Google "SB5000 reviews" you can see what he is talking about.

I like mine, but not everyone was thrilled. Only 56% 5 stars at Amazon. I'm sure price had something to do with it.

OK, thanks. I do have a Fuji camera, X100T, as well and my likely be buying more, say X-Pro2, as my arthritic hands are having trouble with my heavier Pentax DSLRs. I have been considering a Yongnou flash.
