For 35 bucks

It might be worth a shot.

ExpoImaging has just announced a new DSLR attachment for the amateur photographer who wants better flash capability, but doesn’t feel the need to buy an external flash. It’s called the Rogue Safari Pop-Up Flash Booster, and once mounted to your Canon or Nikon SLR, it promises to provide up to 8x more light and a lot more range from your less-than-capable pop-up flash.

1. It looks like just a focusing lens

So my guess is what it will do is extend the range of your flash, which might work for telephoto lenses. I would assume that with a normal or wide angle lens you're going to get a lot of light falloff outside the center. One big problem people have with pop up flashes is leaving them extended when not in use and breaking them off. I would expect this attachment to increase the likelihood of this happening.

For around the same price you can get a used Vivitar 285HV which is a very powerful flash that will cover both wide angle and telephoto. You also get bounce capability. You have to be careful about buying one because the older ones had a very high sync voltage and will blow up the electronics on modern cameras. You can use a voltmeter across the contacts and if it's less than 10v, it's one of the newer ones (which are the most prevalent these days). The main drawback that this type of flash has is it lacks any sort of TTL capability, however in automatic mode (thyristor controlled) it works great so long as you set it to the aperture setting your camera is using. This pretty much forces you to shoot in full manual exposure or aperture priority modes, but I'm in aperture priority 90% of the time anyway.

2. Correct. It is designed for 100mm lenses or longer.
