Summary: I have used this flash a couple of times and have been very happy with the results. It is a little noisy, but I can live with that. It has a little weight to it, but with 4 AA batteries, no more so than what you would expect. I have had several Vivitar products in the past. I have yet to be greatly disappointed.
Pros: Consistent Output, Durable, Easy To Use, Fast Recycling, Powerful Output, Versatile
Summary: I'm a nature shooter and this flash has done wonders for me. It is great at fill light situations and with its adjusting head and diffuser and bounce screen it comes through every time. It is a little heavy but thats mostly battery weight and something you probably cant get away from.
Pros: Consistent Output, Easy To Use, Fast Recycling, Versatile
Summary: Use it on camera, with rechargeable AAs. Recharge time is less than 2 seconds in automatic mode. In full-power its about 5 seconds. For the price, this is the best little flash you can buy. Works great as a slave flash too. The zooming is a little annoying, and I don't really use it. I just set it to manual and set it all the way forward and leave it there. It adds weight to my camera, which is not a con to me, I like it to be heavy and not light and flimsy.
Pros: Consistent Output, Fast Recycling, Powerful Output
Summary: I read reviews all over the internet, trying to find a flash for my D200 that wouldn't break the bank. I finally settled on the DF400z. Yes, as most reviewers on the net will tell you, it doesn't feel as "solid" as a Nikon, but it also isn't as heavy. It works perfectly in iTTL and all other modes. The swivel and bounce have taken my photos to a whole new level....and finally....no more red eye!
Pros: Consistent Output, Easy To Use, Fast Recycling, Lightweight, Powerful Output, Versatile
Summary: it is the perfect unit for my abilities and applications. The staff at B&H have been awesome. They have helped me figure out what I needed and why. I am very happy with my setup matching my skills and usage.
Pros: Consistent Output, Easy To Use, Lightweight, Versatile
Summary: I liked the idea of being able to bounce both in portrait and landscape. The Auto zoom head and built in diffuser is nice. Exposure was good straight on. However, I had a big problem with overexposure in bounce mode, both high and average ceiling heights. It seemed to shoot a full-power flash in bounce. The buttons are a little cheesy too. I'm returning for an SB-400 even though it won't bounce in portrait.
