My SB-800 is dying. Intermittent flashing and I’ve been told since it’s discontinued, it can’t be fixed. I’ve read many many entries on your site to see if I can get a replacement, but I’m hopelessly technically lost. I have a D7100 that’s about 4 or 5 years old and doing well.
So it turns out I have another shoot on Friday. Can you give me a quick suggestion for a replacement and for a remote flash and stand with trigger? I’ve only used an on-camera SB-800, and figure I should upgrade as long as I need to buy a new piece of equipment.
You can replace your SB-800 if you want; there are quite a few available on Amazon for just over $200.
However, if you want to get your flash off your camera a good choice would be the YN-560 IV and trigger. Which is about $100 less than an SB-800 replacement. There are some light quality advantages in getting your flash off your camera. See Scott’s Lighting Interiors e-book for the full story on why and how to get your flash off of your camera.
